1 Explain the cmake build system for wireshark
5 To find out the current state of the cmake implementation for
6 Wireshark, please take a look at "What needs to be done?" below.
7 Basically this is an experiment and if we find out that it works
8 and we like cmake more than autofoo we might switch one day.

20 ========================================================
22 You can find documentation on cmake at: http://www.cmake.org/
24 cmake is designed to support out of tree builds. So much so, that
25 in tree builds do not work properly in all cases.
27 How to do out of tree build (Unix/Linux):
29 2) Assuming, you are in the top directory of the wireshark source
33 5) cmake [options] ../<Name_of_WS_source_dir>
34 6) make (or cmake --build .)
35 7) (as root) umask 0022 && make install
38 In step 5) you may need to override the defaults for features. Common
41 # Disable the POSIX capbabilities check
44 # Enable debugging symbols
45 -DCMAKE_BUILD_TYPE=Debug
53 # Make ccache and clang work together
54 -DCMAKE_C_FLAGS='-Qunused-arguments'
56 # Force Python path on Windows. May be needed if Cygwin's
57 # /usr/bin/python is present and is a symlink
58 # http://public.kitware.com/Bug/view.php?id=13818
59 -DPYTHON_EXECUTABLE=c:/Python27/python
61 # Disable building an application bundle (Wireshark.app) on Mac OS X
62 -DENABLE_APPLICATION_BUNDLE=OFF
65 After running cmake, you can always run "make help" to see
66 a list of all possible make targets.
69 Cmake honors user umask for creating directories as of now:

71 To get predictable results please set umask explicitly.
73 How to do an out of tree build using Visual C++ 2013:
74 [This is advanced alpha and should build all executables except the GTK3
75 Wireshark for 32-bit.]
76 1) Follow http://www.wireshark.org/docs/wsdg_html_chunked/ChSetupWin32.html
78 1a) Set WIRESHARK_BASE_DIR=c:\wireshark (the parent directory of the
80 1b) set WIRESHARK_TARGET_PLATFORM=win32 (or win64)
81 1c) set QT5_BASE_DIR=C:\Qt\5.3\msvc2013_opengl (must match the Qt component path
83 1d) If you want to use Visual Studio make sure that the paths to Python and
84 Cygwin are available to GUI applications. The Python path MUST come first.
86 2a) Build the zlib library, e.g.
87 cd %WIRESHARK_BASE_DIR%\wireshark-%WIRESHARK_TARGET_PLATFORM%-libs\zlib125
88 cmake -G "NMake Makefiles" . # msbuild will not do because of configuration path
90 3) mkdir c:\wireshark\build
91 4) cd c:\wireshark\build
92 5) Run one of the following to create the build environment:
93 cmake -G "NMake Makefiles" path\to\sources (i.e. in case your sources are located at c:\wireshark\trunk, use "..\trunk")
94 cmake path\to\sources (this will build for the latest Visual Studio version found)
95 cmake -G "Visual Studio 12" ("12" builds for VS2103. Use "11" for VS2012 or "10" for VS2010.)
96 cmake -G "Visual Studio 12 Win64" (Win32 is the default)
97 6) Run one of the following to build Wireshark:
98 nmake /X- VERBOSE=1 (or cmake --build . -- VERBOSE=1 )
99 Open Wireshark.sln in Windows Explorer to build in Visual Studio
100 msbuild wireshark.sln /m /p:Configuration=RelWithDebInfo
101 7) In case you want to test the executable(s) inside the build tree:
102 Run setpath.bat whenever it gets updated (there is a message in each cmake
103 run whether it is necessary or not).
107 - Can create project files for many IDEs including Qt Creator, Visual Studio,
110 - Easier to understand/learn
111 - Doesn't create any files in the source tree in case of out of tree builds
112 - One build infrastructure for all of our tier 1 platforms (including Windows)
117 - Everyone who wants to build from source needs cmake
118 - Current state of documentation isn't really better than
119 Autotools documentation. In some respects it's even worse
120 (you need to buy a book to get an explanation as to how
127 All the executables now build from clean source on:
128 * 32 bit openSUSE 11.3: (gnu)make and gcc
131 * 32 bit Ubuntu 10.04
132 * 64 bit Ubuntu 14.04
133 * 64 bit Debian Wheezy
136 * 32 bit Windows using Visual C++ 2013
137 * 64 bit Windows using Visual C++ 2013
140 The Buildbot runs CMake steps on Ubuntu, Win32, Win64, OS X, and Solaris.
142 What needs to be done?
143 ======================
145 - Add back platform specific objects.
146 - Fix places in the cmake files marked as todo.
147 - Guides are not installed.
148 - Build source package (using CPack).
149 This is obsolete if we decide to release VCS snapshots instead
150 - Build packages using CPack: tarball, Windows installer + PortableApps, OS X
151 installer dmg, RPM, SVR4. This includes setting OS target version stuff
152 appropriately for OS X. We currently use NSIS for the Windows installer but
153 should probably use WiX instead.
154 - Add back checkAPI target.
155 - Add support for cmake configurations.
156 - Automatically figure out if *shark is running from the build directory
157 (making WIRESHARK_RUN_FROM_BUILD_DIRECTORY unnecessary like it is with
162 run/qtshark: Mach-O 64-bit x86_64 executable
164 so what you're running from the build directory is the executable
165 itself. autofoo includes libtool in our case, so what you're running
166 from the build directory is a script that then runs the executable,
167 and the executable is in a .libs directory; the code that checks for
168 "running from the build directory?" checks for that.
170 We could perhaps check for the pathname containing "run/", although
171 that wouldn't help if we ran it while *in* the "run" directory;
172 getting an absolute path for the executable would be necessary for
174 - Get plugins loading when running *shark from the build directory.
175 That might involve handling ".libs" and "run" differently.
176 - Get cross-compilation working (or ensure it does). It works with autofoo.
177 - Handle -DFORTIFY_SOURCE=2 appropriately. (Do a Web search for
178 "cmake fortify" for some information.)
179 - Add support for Visual Studio code anlaysis similar to ENABLE_CODE_ANALYSIS in
181 - Define the GTK_DISABLE_ and GDK_DISABLE_ values as appropriate if we
182 care about supporting the GTK+ version.
