用cmake编译gtk程序：gssdp
使用cmake来编译gtk的程序，这里用gupnp中的gssdp的例子来讲解一下。
1、gssdp代码
svn co http://svn.o-hand.com/repos/gupnp/trunk/gssdp gssdp
2、安装cmake
apt-get install cmake
3、编写CMakeLists.txt
project (GSSDP)
include_directories (/usr/include/glib-2.0 /usr/lib/glib-2.0/include
/usr/include/gtk-2.0 /usr/lib/gtk-2.0/include /usr/include/atk-1.0
/usr/include/cairo /usr/include/pango-1.0 /usr/include/freetype2
/usr/include/libpng12 /usr/include/pixman-1 ./ /usr/local/include/gssdp-1.0
/usr/include/libglade-2.0 /usr/include/libsoup-2.4)
aux_source_directory (libgssdp LIB_FILE)
add_library (gssdp SHARED ${LIB_FILE})
set (TOOL_FILE tools/gssdp-device-sniffer.c)
add_executable (gssdp-device-sniffer ${TOOL_FILE} ${LIB_FILE} )
target_link_libraries (gssdp-device-sniffer gssdp soup-2.4 gtk-x11-2.0
gdk-x11-2.0 atk-1.0 gdk_pixbuf-2.0 m pangocairo-1.0 pango-1.0 cairo
gobject-2.0 gmodule-2.0 dl glib-2.0 glade-2.0)
4、解释
其中include的内容和连接库的内容可以使用pkg-config --cflags gtk+-2.0和pkg-config --libs gtk+-2.0里获得，并将他们前面的"-I", "-l"去掉，加入到上面的CMakeLists.txt中
5、编译
在gssdp目录下，建立一个build目录
gssdp/build# cmake .. -- Check for working C compiler: /usr/bin/gcc -- Check for working C compiler: /usr/bin/gcc -- works -- Check size of void* -- Check size of void* - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Configuring done -- Generating done -- Build files have been written to: /home/yutao/study/gupnp_svn/gssdp/build gssdp/build# make Scanning dependencies of target gssdp [ 7%] Building C object CMakeFiles/gssdp.dir/libgssdp/gssdp-socket-source.o [ 15%] Building C object CMakeFiles/gssdp.dir/libgssdp/gssdp-marshal.o [ 23%] Building C object CMakeFiles/gssdp.dir/libgssdp/gssdp-error.o [ 30%] Building C object CMakeFiles/gssdp.dir/libgssdp/gssdp-resource-browser.o [ 38%] Building C object CMakeFiles/gssdp.dir/libgssdp/gssdp-resource-group.o [ 46%] Building C object CMakeFiles/gssdp.dir/libgssdp/gssdp-client.o Linking C shared library libgssdp.so [ 46%] Built target gssdp Scanning dependencies of target gssdp-device-sniffer [ 53%] Building C object CMakeFiles/gssdp-device-sniffer.dir/tools/gssdp-device-sniffer.o [ 61%] Building C object CMakeFiles/gssdp-device-sniffer.dir/libgssdp/gssdp-socket-source.o [ 69%] Building C object CMakeFiles/gssdp-device-sniffer.dir/libgssdp/gssdp-marshal.o [ 76%] Building C object CMakeFiles/gssdp-device-sniffer.dir/libgssdp/gssdp-error.o [ 84%] Building C object CMakeFiles/gssdp-device-sniffer.dir/libgssdp/gssdp-resource-browser.o [ 92%] Building C object CMakeFiles/gssdp-device-sniffer.dir/libgssdp/gssdp-resource-group.o [100%] Building C object CMakeFiles/gssdp-device-sniffer.dir/libgssdp/gssdp-client.o Linking C executable gssdp-device-sniffer [100%] Built target gssdp-device-sniffer
6、运行
#cd ../tools
#../build/gssdp-device-sniffer
7、link情况
#ldd ../build/gssdp-device-sniffer
linux-gate.so.1 => (0xb7f80000)
libgssdp.so => /home/yutao/study/gupnp_svn/gssdp/build/libgssdp.so (0xb7f74000)
即link的内容是自己编译出来的libgssdp.so
8、编译目录信息
build# ls CMakeCache.txt CMakeFiles cmake_install.cmake gssdp-device-sniffer libgssdp.so Makefile9、编译中可能需要的库
apt-get install libsoup2.4-dev
