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

22 ==============================
24 You can find documentation on cmake at: http://www.cmake.org/
26 cmake is designed to support out of tree builds. So much so, that
27 in tree builds do not work properly in all cases.
29 How to do out of tree build (Unix/Linux):
31 2) Assuming, you are in the top directory of the wireshark source
35 5) cmake ../<Name_of_WS_source_dir>
36 6) make (or cmake --build .)
37 7) (as root) umask 0022 && make install
40 in step 5), you may override the defaults for features:
41 cmake -DENABLE_CAP=OFF ../<Name_of_WS_source_dir>
42 will disable the capabilities check.
45 On OS X, you may want to run cmake like this:
46 cmake -DENABLE_CAP=OFF -G "Unix Makefiles"
49 After running cmake, you can always run "make help" to see
50 a list of all possible make targets.
53 Cmake honors user umask for creating directories as of now:
54 http://public.kitware.com/Bug/view.php?id=9620
55 To get predictable results please set umask explicitly.
57 How to do out of tree build (Win32/64):
58 [This is early alpha and while the build should build all executables except
59 the GUIs don't waste your time testing unless you are willing to fix things
61 1) Follow http://www.wireshark.org/docs/wsdg_html_chunked/ChSetupWin32.html
63 1a) Set WIRESHARK_BASE_DIR=c:\wireshark (the parent directory of the
65 1b) set WIRESHARK_TARGET_PLATFORM=win32 (or win64)
66 1c) set QT5_BASE_DIR=c:\Qt\Qt5.1.1\5.1.1 (or whatever)
68 3) mkdir c:\wireshark\build
69 4) cd c:\wireshark\build
70 5) cmake -G "NMake Makefiles" -DBUILD_wireshark=OFF path\to\sources
71 (i.e. in case your sources are located at c:\wireshark\trunk, use "..\trunk")
72 5a) cmake path\to\sources (this will build for the latest Visual Studio version found)
73 6) nmake /X- VERBOSE=1 (or cmake --build . -- VERBOSE=1 )
74 6a) Wireshark.sln (this will run up Visual Studio with the cmake built solution
75 7) In case you want to test the executable(s) inside the build tree:
76 Run setpath.bat whenever it gets updated (there is a message in each cmake
77 run whether it is necessary or not).
81 - Can create project files for some MS and Apple IDEs.
83 - Easier to understand/learn
84 - Doesn't create any files in the source tree in case
86 - One build infrastructure even including Windows
92 - Everyone who wants to build from source needs cmake
93 - Current state of documentation isn't really better than
94 autofoo documentation, in some respect it's even worse
95 (you need to buy a book to get an explanation as to how
102 All the executables now build from clean source on:
103 * 32bit openSUSE 11.3: (gnu)make and gcc
107 * 64bit Debian Wheezy
109 What needs to be done?
110 ======================
112 - Add back platform specific objects.
113 - Fix places in the cmake files marked as todo.
114 - Guides are not installed.
115 - Release notes are not built.
116 - Build source package (using CPack).
117 This is obsolete if we decide to release VCS snapshots instead
118 - Build rpm package (using CPack).
119 - Build dpkg package (using CPack).
120 This is obsolete, we should call CMake from debian/rules instead, using dh
122 - Add back checkAPI target.
123 - Test and add support for other platforms (BSDs, OSX,
124 Solaris, Win32, Win64, ...)
