++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++ [[ChapterTools]] == Tool Reference [[ChToolsIntro]] === Introduction This chapter will provide you with information about the various tools needed for Wireshark development. None of the tools mentioned in this chapter are needed to run Wireshark; they are only needed to build it. Most of these tools have their roots on UNIX like platforms, but Windows ports are also available. Therefore the tools are available in different "flavours": * UNIX (or Windows Cygwin): the tools should be commonly available on the supported UNIX platforms, and for Windows platforms by using the Cygwin UNIX emulation * Windows native: some tools are available as native Windows tools, no special emulation is required. Many of these tools can be installed (and updated) using http://chocolatey.org[Chocolatey], a Windows package manager similar to the Linux package managers apt-get or yum. [WARNING] .Follow the directions ==== Unless you know exactly what you are doing, you should strictly follow the recommendations given in <>. ==== The following sections give a very brief description of what a particular tool is doing, how it is used in the Wireshark project and how it can be installed and tested. Documentation for these tools is outside the scope of this document. If you need further information on using a specific tool you should find lots of useful information on the web, as these tools are commonly used. You can also get help for the UNIX based tools with `toolname --help` or the man page via `man toolname`. You will find explanations of the tool usage for some of the specific development tasks in <>. [[ChToolsWindowsPowerShell]] === Windows PowerShell PowerShell 2.0 or later is required for building Wireshark and the NSIS package. Windows 7 and later include compatible versions. If you are running Windows Vista and have thus far managed to not install PowerShell 2.0, either directly or via anything that requires it, you must now install PowerShell 2.0. You can download it from https://www.microsoft.com/powershell[] === Chocolatey Chocolatey is a Windows package manager that can be used to install (and update) many of the packages required for Wireshark development. Chocolatey can be obtained from the http://chocolatey.org[website] or from a DOS command prompt: ---- C:\>@powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin ---- or a Powershell prompt: ---- PS:\>iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1')) ---- [[ChToolsCygwin]] === Windows: Cygwin Cygwin provides a lot of UNIX based tools on the Windows platform. It uses a UNIX emulation layer which might be a bit slower compared to the native Windows tools, but at an acceptable level. The installation and update is pretty easy and done through a single utility, 'setup-x86.exe' for 32-bit Windows and 'setup-x86_64.exe' for 64-bit Windows. The native Windows tools will typically be a bit faster but more complicated to install, as you would have to download the tools from different web sites and install and configure them individually. [NOTE] .You must have Cygwin installed ==== As there's no Windows native bash version available, at least a basic installation of Cygwin is required in any case. This may change in the future as packaging systems such as NuGet and Chocolatey mature. ==== Although Cygwin consists of several separate packages, the installation and update is done through a single utility, 'setup-x86.exe' or 'setup-x86_64.exe', which acts similarly to other web based installers. Alternatively you can install Cygwin and its packages using Chocolatey. ==== Installing Cygwin using the Cygwin installer You will find 'setup-x86.exe', for 32-bit systems, and 'setup-x86_64.exe', for 64-bit systems, at http://www.cygwin.com/install.html[]. Click on the link for the appropriate setup utility to download it. After the download completes, run it. All tools will be installed into one base folder. The default is 'C:\cygwin'. The setup utility will ask you for some settings. The defaults should usually work well, at least initially. If, at the "Choose A Download Source" page, you use the default "Install from Internet" setting, you will need to choose a download site at the "Choose A Download Site" page. See the list of mirror sites at http://cygwin.com/mirrors.html[] to choose a download site appropriate to your location. At the "Select Packages" page, you'll need to select some additional packages, which are not installed by default. Navigate to the required Category/Package row and click on the "Skip" item in the "New" column so it shows a version number for the required package. After clicking the Next button several times the setup will then download and install the selected packages (this may take a while, depending on the package size). Under: 'Start->Programs->Cygwin->Cygwin Bash Shell' you should now be able to start a new Cygwin bash shell, which is similar to the standard Windows command line interpreters (command.com / cmd.exe) but much more powerful. [[ChToolsCygwinPackages]] ==== Add/Update/Remove Cygwin Packages If you want to add, update, or remove packages later you can do so by running the setup utility again. At the "Select Packages" page, the entry in the "New" column will control what is done (or not) with the package. If a new version of a package is available, the new version number will be displayed, so it will be automatically updated. You can change the current setting by simply clicking at it, it will change between: * 'A specific version number.' This specific package version will be installed. * 'Skip.' Not installed, no changes. * 'Keep.' Already installed, no changes. * 'Uninstall.' Uninstall this package. * 'Reinstall.' Reinstall this package. ==== Installing Cygwin using Chocolatey Chocolatey supports Cygwin as an external package source. To install Cygwin itself run ---- PS$>choco install cygwin # You might also need to install cyg-get: PS$>choco install cyg-get ---- Chocolatey installs Cygwin in 'C:\tools\cygwin' by default. One or more Cygwin packages can be installed using "cyg-get": ---- PS$>cyg-get sed asciidoc ---- [[ChToolsGNUChain]] === GNU compiler toolchain (UNIX only) [[ChToolsGCC]] ==== gcc (GNU compiler collection) The GCC C compiler is available for most of the UNIX-like platforms. If GCC isn't already installed or available as a package for your platform, you can get it at: http://gcc.gnu.org/[]. After correct installation, typing at the bash command line prompt: ---- $ gcc --version ---- should result in something like ---- gcc (Ubuntu 4.9.1-16ubuntu6) 4.9.1 Copyright (C) 2014 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. ---- Your version string may vary, of course. [[ChToolsGDB]] ==== gdb (GNU project debugger) GDB is the debugger for the GCC compiler. It is available for many (if not all) UNIX-like platforms. If you don't like debugging using the command line there are some GUI frontends for it available, most notably GNU DDD. If gdb isn't already installed or available as a package for your platform, you can get it at: http://www.gnu.org/software/gdb/gdb.html[]. After correct installation: ---- $ gdb --version ---- should result in something like: ---- GNU gdb (Ubuntu 7.8-1ubuntu4) 7.8.0.20141001-cvs Copyright (C) 2014 Free Software Foundation, Inc.

Type "show copying" and "show warranty" for details. This GDB was configured as "x86_64-linux-gnu". Type "show configuration" for configuration details. For bug reporting instructions, please see: . Find the GDB manual and other documentation resources online at: . For help, type "help". Type "apropos word" to search for commands related to "word". ---- Your version string may vary, of course. [[ChToolsDDD]] ==== ddd (GNU Data Display Debugger) The GNU Data Display Debugger is a good GUI frontend for GDB (and a lot of other command line debuggers), so you have to install GDB first. It is available for many UNIX-like platforms. If GNU DDD isn't already installed or available as a package for your platform, you can get it at: http://www.gnu.org/software/ddd/[]. [[ChToolsGNUmake]] ==== make (GNU Make) [NOTE] .GNU make isn't supported either for Windows GNU Make is available for most of the UNIX-like platforms. If GNU Make isn't already installed or available as a package for your platform, you can get it at: http://www.gnu.org/software/make/[]. After correct installation: ---- $ make --version ---- should result in something like: ---- GNU Make 4.0 Built for x86_64-pc-linux-gnu Copyright (C) 1988-2013 Free Software Foundation, Inc.

There is NO WARRANTY, to the extent permitted by law. ---- Your version string may vary, of course. [[ChToolsMSChain]] === Microsoft compiler toolchain (Windows native) To compile Wireshark on Windows using the Microsoft C/$$C++$$ compiler, you'll need: . C compiler (`cl.exe`) . Assembler (`ml.exe` for 32-bit targets and `ml64.exe` for 64-bit targets) . Linker (`link.exe`) . C runtime headers and libraries (e.g. 'stdio.h', 'msvcrt.lib') . Windows platform headers and libraries (e.g. 'windows.h', 'WSock32.lib') + // Can we drop support for CHM? . HTML help headers and libraries ('htmlhelp.h', 'htmlhelp.lib') ==== Toolchain Package Alternatives The Wireshark 2.0.x releases are compiled using Microsoft Visual $$C++$$ 2013. The official Wireshark 1.12.x and 1.10.x releases are compiled using Microsoft Visual $$C++$$ 2010 SP1. The official 1.8 releases were compiled using Microsoft Visual $$C++$$ 2010 SP1 as well. The official 1.6, 1.4, and 1.2 releases were compiled using Microsoft Visual $$C++$$ 2008 SP1. Other past releases, including the 1.0 branch, were compiled using Microsoft Visual $$C++$$ 6.0. Using the release compilers is recommended for Wireshark development work. The older "Express Edition" compilers such as Visual $$C++$$ 2010 Express Edition SP1 can be used but any PortableApps packages you create with them will require the installation of a separate Visual $$C++$$ Redistributable package on any machine on which the PortableApps package is to be used. See <> below for more details. However, you might already have a different Microsoft $$C++$$ compiler installed. It should be possible to use any of the following with the considerations listed: .Visual C++ 2013 Community Edition IDE + Debugger?:: Yes Purchase required?:: http://www.visualstudio.com/en-us/downloads/download-visual-studio-vs#d-community[Free Download] SDK required for 64-bit builds?:: No CMake Generator: `Visual Studio 12` .Visual C++ 2010 Express Edition IDE + Debugger?:: Yes Purchase required?:: http://www.microsoft.com/express/Downloads/#Visual_Studio_2010_Express_Downloads[Free Download] SDK required for 64-bit builds?:: Yes.

The version of '$$vcredist_x86.exe$$' or '$$vcredist_x64.exe$$' _must_ match the version for your compiler including any service packs installed for the compiler.] .Visual Studio 2010 IDE + Debugger?:: Yes Purchase required?:: Yes SDK required for 64-bit builds?:: No CMake Generator: `Visual Studio 10` Remarks:: Building a 64-bit installer requires a a $$C++$$ redistributable ('$$vcredist_x86.exe$$').footnoteref[vcredist] You can use Chocolatey to install Visual Studio, e.g: ---- PS:\> choco install VisualStudioCommunity2013 ---- ==== cl.exe (C Compiler) The following table gives an overview of the possible Microsoft toolchain variants and their specific C compiler versions ordered by release date. |=============== |Compiler Package|cl.exe|_MSC_VER|CRT DLL |Visual Studio 2013|12.0|1800|msvcr120.dll |Visual Studio 2010|10.0|1600|msvcr100.dll |Visual Studio 2010 Express Edition |=============== After correct installation of the toolchain, typing at the Visual Studio Command line prompt (cmd.exe): ---- > cl ---- should result in something like: ---- Microsoft (R) C/C++ Optimizing Compiler Version 18.00.31101 for x86 Copyright (C) Microsoft Corporation. All rights reserved. usage: cl [ option... ] filename... [ /link linkoption... ---- However, the version string may vary. Documentation on the compiler can be found at http://msdn.microsoft.com/en-us/library/wk21sfcf.aspx[Microsoft MSDN] ==== link.exe (Linker) After correct installation, typing at the Visual Studio Command line prompt (cmd.exe): ---- > link ---- should result in something like: ---- Microsoft (R) Incremental Linker Version 12.00.31101.0 Copyright (C) Microsoft Corporation. All rights reserved. usage: LINK [options] [files] [@commandfile] ... ---- However, the version string may vary. Documentation on the linker can be found at http://msdn.microsoft.com/en-us/library/t2fck18t.aspx[Microsoft MSDN] [[msvc-runtime-redistributable]] ==== C-Runtime "Redistributable" Files Please note: The following is not legal advice - ask your preferred lawyer instead. It's the authors view and this view might be wrong. Depending on the Microsoft compiler version you use, some binary files coming from Microsoft might be required to be installed on Windows machine to run Wireshark. On a developer machine, the compiler setup installs these files so they are available - but they might not be available on a user machine! This is especially true for the C runtime DLL (msvcr*.dll), which contains the implementation of ANSI and alike functions, e.g.: fopen(), malloc(). The DLL is named like: msvcr'version'.dll, an abbreviation for "MicroSoft Visual C Runtime". For Wireshark to work, this DLL must be available on the users machine. Starting with MSVC7, it is necessary to ship the C runtime DLL (msvcr'version'.dll) together with the application installer somehow, as that DLL is possibly not available on the target system. [NOTE] .Make sure you're allowed to distribute this file ==== The files to redistribute must be mentioned in the redist.txt file of the compiler package. Otherwise it can't be legally redistributed by third parties like us. ==== The following MSDN link is recommended for the interested reader: * http://msdn.microsoft.com/en-us/library/ms235299.aspx[Redistributing Visual C++ Files] In all cases where '$$vcredist_x86.exe$$' or '$$vcredist_x64.exe$$' is downloaded it should be downloaded to the directory into which the support libraries for Wireshark have been downloaded and installed. This directory is specified by the WIRESHARK_BASE_DIR or WIRESHARK_LIB_DIR environment variables. It need not, and should not, be run after being downloaded. ===== msvcr120.dll / vcredist_x86.exe / vcredist_x64.exe - Version 12.0 (2013) There are three redistribution methods that MSDN mentions for MSVC 2013 (see: http://msdn.microsoft.com/en-us/library/vstudio/ms235316(v=vs.120).aspx["Choosing a Deployment Method"]): . 'Using Visual $$C++$$ Redistributable Package'. The Microsoft libraries are installed by copying '$$vcredist_x64.exe$$' or '$$vcredist_x86.exe$$' to the target machine and executing it on that machine (MSDN recommends this for applications built with Visual Studio 2013) . 'Using Visual $$C++$$ Redistributable Merge Modules'. (Loadable modules for building msi installers. Not suitable for Wireshark's NSIS based installer) . 'Install a particular Visual $$C++$$ assembly as a private assembly for the application'. The Microsoft libraries are installed by copying the folder content of 'Microsoft.VC120.CRT' to the target directory (e.g. 'C:\Program Files\Wireshark') To save installer size, and to make a portable version of Wireshark (which must be completely self-contained, on a medium such as a flash drive, and not require that an installer be run to install anything on the target machine) possible, when building 32-bit Wireshark with MSVC2013, method 3 (copying the content of 'Microsoft.VC120.CRT') is used (this produces the smallest package). ==== Windows (Platform) SDK The Windows Platform SDK (PSDK) or Windows SDK is a free (as in beer) download and contains platform specific headers and libraries (e.g. 'windows.h', 'WSock32.lib', etc.). As new Windows features evolve in time, updated SDK's become available that include new and updated APIs. When you purchase a commercial Visual Studio or use the Community Edition, it will include an SDK. The free Express (as in beer) downloadable C compiler versions (V$$C++$$ 2012 Express, V$$C++$$ 2012 Express, etc.) do not contain an SDK -- you'll need to download a PSDK in order to have the required C header files and libraries. Older versions of the SDK should also work. However, the command to set the environment settings will be different, try search for SetEnv.* in the SDK directory. ==== HTML Help HTML Help is used to create the User's and Developer's Guide in .chm format and to show the User's Guide as the Wireshark "Online Help". Both features are currently optional, and might be removed in future versions. ===== HTML Help Compiler (hhc.exe) This compiler is used to generate a .chm file from a bunch of HTML files -- in our case to generate the User's and Developer's Guide in .chm format. The compiler is only available as the free (as in beer) "HTML Help Workshop" download. If you want to compile the guides yourself, you need to download and install this. If you don't install it into the default directory, you may also have a look at the HHC_DIR setting in the file docbook/Makefile. ===== HTML Help Build Files (htmlhelp.c / htmlhelp.lib) The files 'htmlhelp.c' and 'htmlhelp.lib' are required to be able to open .chm files from Wireshark and show the online help. Both files are part of the SDK (standalone (P)SDK or MSVC since 2002). [[ChToolsDebugger]] ==== Debugger Using a good debugger can save you a lot of development time. The debugger you use must match the C compiler Wireshark was compiled with, otherwise the debugger will simply fail or you will only see a lot of garbage. [[ChToolsMSVCDebugger]] ===== Visual Studio integrated debugger You can use the integrated debugger of Visual Studio if your toolchain includes it. Open the solution in your build directory and build and debug as normal with a Visual Studio solution. To set the correct paths for Visual Studio when running Wireshark under the debugger, add the build output directory to the path before opening Visual Studio from the same command prompt, e.g. ---- C:\Development\wsbuild32>set PATH="%PATH%;C:\Development\wsbuild32\run\RelwithDebInfo" C:\Development\wsbuild32>wireshark.sln ---- for PowerShell use ---- PS C:\Development\wsbuild32>$env:PATH += ";$(Convert-Path run\RelWithDebInfo)" PS C:\Development\wsbuild32>wireshark.sln ---- When Visual Studio has finished loading the solution, set the executable to be run in the debugger, e.g. Executables\Wireshark, by right clicking it in the Solution Explorer window and selecting "Set as StartUp Project". Also set the Solution Configuration (usually RelWithDebInfo) from the droplist on the toolbar. NOTE: Currently Visual Studio regards a command line build as incomplete, so will report that some items need to be built when starting the debugger. These can either be rebuilt or ignored as you wish. The normal build is an optimised release version so debugging can be a bit difficult as variables are optimised out into registers and the execution order of statements can jump around. If you require a non-optimised version, then build using a debug configuration. [[ChToolsMSDebuggingTools]] ===== Debugging Tools for Windows You can also use the Microsoft Debugging Tools for Windows toolkit, which is a standalone GUI debugger. Although it's not that comfortable compared to debugging with the Visual Studio integrated debugger it can be helpful if you have to debug on a machine where an integrated debugger is not available. You can get it free of charge from Microsoft in several ways, see the http://msdn.microsoft.com/en-us/library/windows/hardware/ff551063%28v=vs.85%29.aspx)[Debugging tools for Windows] page. You can also use Chocolatey to install WinDbg: ---- PS:\> choco install windbg ---- To debug Wireshark using WinDbg, open the built copy of Wireshark using the File -> Open Executable... menu, i.e. C:\Development\wsbuild32\run\RelWithDebInfo\Wireshark.exe. To set a breakpoint open the required source file using the File -> Open Source File... menu and then click on the required line and press F9. To run the program, press F5. If you require a non-optimised version, then build using a debug configuration, e.g. `msbuild /m /p:Configuration=Debug Wireshark.sln`. The build products will be found in C:\Development\wsbuild32\run\Debug\. [[ChToolsBash]] === bash The bash shell is needed to run several shell scripts. [[ChToolsGNUBash]] ==== UNIX and Cygwin: GNU bash The bash shell is available for most of the UNIX-like platforms and as the bash package from the <>. If bash isn't already installed or available as a package for your platform, you can get it at http://www.gnu.org/software/bash/bash.html[]. After correct installation, typing at the bash command line prompt: ---- $ bash --version ---- should result in something like: ---- GNU bash, version 3.1.17(6)-release (i686-pc-cygwin) Copyright (C) 2005 Free Software Foundation, Inc. ---- However, the version string may vary. [[ChToolsWindowsBash]] ==== Windows native: // MinGW? PowerShell? **** This section not yet written **** [[ChToolsPython]] === Python Python is an interpreted programming language. The homepage of the Python project is http://python.org/[]. It is used to generate some source files. Python 2.5 or later (including Python 3) should work fine but Python 2.7 is recommended. Python is either included or available as a package on most UNIX-like platforms. Windows packages and source are available at http://python.org/download/[]. The Cygwin Python package is *not* recommended since `/usr/bin/python` is a symbolic link, which causes confusion outside Cygwin. You can also use Chocolatey to install Python: ---- PS:\> choco install Python2 ---- Chocolatey installs Python 2 into 'C:\tools\python2' by default. You can verify your Python version by running ---- $ python --version ---- on UNIX and Linux and ---- rem Official package C:> cd python27 C:Python27> python --version rem Chocolatey C:> cd \tools\python2 C:\tools\python2> python --version ---- on Windows. You should see something like ---- Python 2.7.9 ---- Your version string may vary of course. [[ChToolsPerl]] === Perl Perl is an interpreted programming language. The homepage of the Perl project is http://www.perl.com[]. Perl is used to convert various text files into usable source code. Perl version 5.6 and above should work fine. [[ChToolsUnixPerl]] ==== UNIX and Cygwin: Perl Perl is available for most of the UNIX-like platforms and as the perl package from the <>. If perl isn't already installed or available as a package for your platform, you can get it at http://www.perl.com/[].

They aren't officially supported but _should_ work. [[ChToolsGit]] === Git client The Wireshark project uses its own Git repository to keep track of all the changes done to the source code. Details about the usage of Git in the Wireshark project can be found in <>. If you want to work with the source code and are planning to commit your changes back to the Wireshark community, it is recommended to use a Git client to get the latest source files. For detailed information about the different ways to obtain the Wireshark sources, see <>. You will find more instructions in <> on how to use the Git client. [[ChToolsUnixGit]] ==== UNIX or Cygwin: git Git is available for most of the UNIX-like platforms and as the Git package from the <> If Git isn't already installed or available as a package for your platform, you can get it at: http://git-scm.com/[].

[[ChToolsGitPowerShellExtensions]] === Git Powershell Extensions (optional) A useful tool for command line git on Windows is https://github.com/dahlbyk/posh-git[PoshGit]. Poshgit provides git command completion and alters the prompt to indicate the local working copy status. You can install it using Chocolatey: ---- PS:\>choco install poshgit ---- [[ChToolsGitGUI]] === Git GUI client (optional) Along with the traditional command-line client, several GUI clients are available for a number of platforms. See http://git-scm.com/downloads/guis[] for details. // [[ChToolsUnixGitGUI]] // XXX Add Gui client section [[ChToolsPatch]] === patch (optional) The patch utility is used to merge a diff file into your own source tree. This tool is only needed, if you want to apply a patch (diff file) from someone else (probably from the developer mailing list) to try out in your own private source tree. It most cases you may not need the patch tool installed. Git and Gerrit should handle patches for you. You will find more instructions in <>on how to use the patch tool.
