++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++ [[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 [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 <>. [[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 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. All tools will be installed into one base folder. The default is 'C:\cygwin'. 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. 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. [[ChToolsGNUChain]] === GNU compiler toolchain (UNIX only) [[ChToolsGCC]] ==== gcc (GNU compiler collection) The GCC C compiler is available for most of the UNIX-like platforms and as the Devel/gcc package from the <>. 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 (GCC) 3.4.4 (cygwin special) (gdc 0.12, using dmd 0.125) Copyright (C) 2004 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 and as the Devel/gdb package from the <> 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 6.5.50.20060706-cvs (cygwin-special) Copyright 2003 Free Software Foundation, Inc. GDB is free software, covered by the GNU General Public License, and you are welcome to change it and/or distribute copies of it under certain conditions. Type "show copying" to see the conditions. There is absolutely no warranty for GDB. Type "show warranty" for details. This GDB was configured as "i686-pc-cygwin". ---- 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 and as the ddd package from the <>. 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 ==== Although some effort is made to use make from the Cygwin environment, the mainline is still using Microsoft Visual Studio's nmake. ==== GNU Make is available for most of the UNIX-like platforms and also as the Devel/make package from the <>. 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/[].

[[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`) . Make (`nmake.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 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. "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++ 2010 Express Edition (recommended) 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. config.nmake MSVC_VARIANT:: MSVC2010EE 32-bit environment setup:: `%PROGRAMFILES%\Microsoft Visual Studio 10.0\VC\vcvarsall.bat x86` 64-bit environment setup:: `%PROGRAMFILES%\Microsoft Visual Studio 10.0\VC\vcvarsall.bat x64` Remarks:: Installers created using express editions require a $$C++$$ redistributable ('$$vcredist_x86.exe$$' or '$$vcredist_x86.exe$$').footnoteref[vcredist,'$$vcredist_x86.exe$$' (3MB free download) is required to build Wireshark-win32-wireshark-major-minor-version:[].x.exe, and '$$vcredist_x64.exe$$' is required to build Wireshark-win64-wireshark-major-minor-version:[].x.exe.

Please note: The following is not legal advice - ask your preferred lawyer instead. It's the author's view, but this view might be wrong. The myriad of http://anonsvn.wireshark.org/wireshark-win32-libs/tags/[Win32 support lib] port projects all seem to believe there are legal issues involved in using newer versions of Visual Studio. This FUD essentially stems from two misconceptions: . Unfortunately, it is believed by many that the Microsoft Visual Studio 2003 EULA explicitly forbids linking with GPL'ed programs. This belief is probably due to an improper interpretation of the http://msdn.microsoft.com/visualc/vctoolkit2003/eula.aspx[Visual Studio 2003 Toolkit EULA], which places redistribution restrictions only on SOURCE CODE SAMPLES which accompany the toolkit. . Other maintainers believe that the GPL itself forbids using Visual Studio 2003 since one of the required support libraries (MSVCR71.DLL) does not ship with the Windows operating system. This is also a wrongful interpretation, and the http://www.gnu.org/licenses/gpl-faq.html#WindowsRuntimeAndGPL[GPL FAQ] explicitly addresses this issue. The situation is similar for Visual Studio 2005 and later. It should be perfectly legal to compile Wireshark, distribute, run it if it was compiled with any MSVC version > V6. ==== 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 2005|8.0|1400|msvcr80.dll |Visual $$C++$$ 2005 Express Edition |.NET Framework 2.0 SDK |Windows SDK for Windows Vista and .NET Framework 3.0 Runtime Components |Visual Studio 2008|9.0|1500|msvcr90.dll |Visual Studio 2008 Express Edition |Visual Studio 2010|10.0|1600|msvcr100.dll |Visual Studio 2010 Express Edition |=============== After correct installation of the toolchain, typing at the command line prompt (cmd.exe): ---- > cl ---- should result in something like: ---- Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 15.00.30729.01 for 80x86 Copyright (C) Microsoft Corp. All rights reserved. usage: cl [ option... ] filename... [ /link linkoption... ---- However, the version string may vary. [[ChToolsNMake]] ==== nmake.exe (Make) Nmake is part of the toolchain packages described above. Instead of using the workspace (.dsw) and projects (.dsp) files, the traditional nmake makefiles are used. This has one main reason: it makes it much easier to maintain changes simultaneously with the GCC toolchain makefile.am files as both file formats are similar. However, as no Visual Studio workspace/project files are available, this makes it hard to use the Visual Studio IDE e.g. for using the integrated debugging feature. After correct installation, typing at the command line prompt (cmd.exe): ---- > nmake ---- should result in something like: ---- Microsoft (R) Program Maintenance Utility Version 6.00.9782.0 Copyright (C) Microsoft Corp 1988-1998. All rights reserved. NMAKE : fatal error U1064: MAKEFILE not found and no target specified Stop. ---- However, the version string may vary. Documentation on nmake can be found at http://msdn2.microsoft.com/library/dd9y37ha(VS.71).aspx[Microsoft MSDN] ==== link.exe (Linker) **** This section not yet written **** [[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 links are recommended for the interested reader: * http://msdn2.microsoft.com/library/ms235299(VS.80).aspx[Redistributing Visual C++ Files] * http://msdn2.microsoft.com/library/ms235291(VS.80).aspx[How to: Deploy using XCopy] * http://support.microsoft.com/?scid=kb%3Ben-us%3B326922&x=10&y=13[Redistribution of the shared C runtime component in Visual $$C++$$ 2005 and in Visual $$C++$$ .NET] 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_LIB_DIR setting in the 'config.nmake'. By default it is 'C:\wireshark-win32-libs'. It need not, and should not, be run after being downloaded. ===== msvcr80.dll / vcredist_x86.exe - Version 8.0 (2005) There are three redistribution methods that MSDN mentions for MSVC 8 (see http://msdn.microsoft.com/library/ms235316(VS.80).aspx["Choosing a Deployment Method"]): . 'Using Visual $$C++$$ Redistributable Merge Modules'. (Loadable modules for building msi installers. Not suitable for Wireshark's NSIS based installer) . 'Using Visual $$C++$$ Redistributable Package'. The Microsoft libraries are installed by copying '$$vcredist_x86.exe$$', '$$vcredist_x64.exe$$', or '$$vcredist_ia64.exe$$' to the target machine and executing it on that machine (MSDN recommends this for applications built with Visual Studio 2005 Express Edition). . '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.VC80.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 MSVC2005, method 3 (copying the content of 'Microsoft.VC80.CRT') is used (this produces the smallest package). As MSVC2005EE and DOTNET20 don't provide the folder 'Microsoft.VC80.CRT', when 32-bit Wireshark is built with either of them method 2 is used. You'll have to download the appropriate version of '$$vcredist_x86.exe$$' from Microsoft for your compiler version. A portable version of 64-bit Wireshark is not built, so method 3 is used for all 64-bit builds. You'll have to download the appropriate version of '$$vcredist_x64.exe$$' or '$$vcredist_ia64.exe$$' from Microsoft for your target processor and compiler version. * For 32-bit builds using Microsoft Visual $$C++$$ 2005 Express Edition without Service Pack 1, you need '8.0.50608.0', from: "Microsoft Visual $$C++$$ 2005 Redistributable Package (x86)": http://www.microsoft.com/download/details.aspx?id=3387[]. * For 64-bit x86 (x64) builds using Microsoft Visual $$C++$$ 2005, any edition, without Service Pack 1, you need '{fill this in}', from: "Microsoft Visual $$C++$$ 2005 Redistributable Package (x64)": http://www.microsoft.com/download/details.aspx?id=21254[]. * For IA-64 builds using Microsoft Visual $$C++$$ 2005, any edition, without Service Pack 1, you need '{fill this in}', from: "Microsoft Visual $$C++$$ 2005 Redistributable Package (IA64)": http://www.microsoft.com/download/details.aspx?id=16326[]. * For 32-bit builds using Microsoft Visual $$C++$$ 2005 Express Edition with Service Pack 1, you need '8.0.50727.762', from: "Microsoft Visual $$C++$$ 2005 SP1 Redistributable Package (x86)": http://www.microsoft.com/download/details.aspx?id=5638[]. * For 64-bit x86 builds using Microsoft Visual $$C++$$ 2005, any edition, with Service Pack 1, you need '{fill this in}', from: "Microsoft Visual $$C++$$ 2005 SP1 Redistributable Package (x64)": http://www.microsoft.com/download/details.aspx?id=18471[].

Please report to the developer mailing list, if you find a different version number! ==== 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, it will include an SDK. The free (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. Prior to Windows Vista, the name "Platform SDK" was used; starting with Vista, the name was changed just to "Windows Software Development Kit" or "Windows SDK". The full names of the SDKs can be misleading; for example, the SDK for Vista was called the "Microsoft Windows Software Development Kit for Windows Vista and .NET Framework 3.0 Runtime Components", which really means the Windows SDK for Windows Vista and Platforms (like WinXP) that have the .NET 3.0 runtime installed. ==== 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). Simply set HHC_DIR in 'config.nmake' to use it. [[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. However, setting up the environment is a bit tricky, as the Windows build process uses makefiles instead of the .dsp/.dsw files usually used. **** This section not yet written **** [[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 at: http://www.microsoft.com/whdc/devtools/debugging/default.mspx[] (as links to Microsoft pages change from time to time, search for "Debugging Tools" at their page if this link happens to be outdated).
