Hello, In this moment, cmake support for tqtinterface, arts and kdelibs are ready for building tests. Some info about cmake build system: 1) preffered mode for building are "out-of-source", which prevent sources to be "polluted" with generated files and compiled objects (in kde4 out-of-source mode are mandatory). For example, tqtinterfaces will be configured in this way: mkdir /tmp/tqtinterface cd /tmp/tqtinterface svn co svn://anonsvn.kde.org/home/kde/branches/trinity/dependencies/tqtinterface mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX=/usr ../tqtinterface make -j 3 make install DESTDIR=/tmp/tqtinterface/install 2) There are some standard rules to activate/deactivate features: For example, kdelibs have: WITH_LIBART, WITH_ARTS, WITH_TIFF, etc (for rest of options check kdelibs/CMakeLists.txt) For compile kdelibs with arts and tiff and without aspell, we will run: cmake -DWITH_ARTS=ON -DWITH_TIFF=ON -DWITH_ASPELL=OFF <path_to_sources> 3) If we need to alter standard install directories we have variables like BIN_INSTALL_DIR, SYSCONFDIR, XDG_MENUDIR. Example: cmake cmake -DCMAKE_INSTALL_PREFIX=/opt/kde3 -DSYSCONFDIR=/etc <sources> 4) Enabling RPATH: cmake -DCMAKE_INSTALL_RPATH=/usr/kde/3.5/lib ################################### (almost) complete example, kdelibs for ubuntu: cmake -DCMAKE_INSTALL_PREFIX=/opt/kde3 \ -DINCLUDE_INSTALL_DIR=/opt/kde3/include/kde \ -DSYSCONFDIR=/etc \ -DWITH_LIBIDN=ON -DWITH_SSL=ON -DWITH_LIBART=ON \ -DWITH_ALSA=ON -DWITH_ARTS=ON -DWITH_CUPS=ON \ -DWITH_JASPER=ON -DWITH_OPENEXR=ON -DWITH_ASPELL=ON \ -DWITH_TIFF=ON -DWITH_LUA=OFF \ <path to kdelibs sources> LUA support are disabled because is not done yet. If you won't using RPATH, ensure that LD_LIBRARY_PATH is correcty set, otherwise kdelibs will fail when will try to use mcopidl. For testing, are preferable to use big number of concurrent compile processes (-j 10, for example), to check if all dependencies are compiled in proper order. -- Serghei
