Hi, Which version of cmake are you using for precompiled header ? Here is the ouptut of gcc when compiling headers: /usr/bin/c++ -I/home/heefre/svn/trunk/voxgratia/opal/include;-I/home/heefre/svn/trunk/voxgratia/ptlib_unix/include;-I/usr/include/xsd;-I/usr/include;-I/home/heefre/svn/trunk/FsmCompiler/language/cpp/include;-I/home/heefre/svn/trunk/voxgratia/OpalTester/include;-I/home/heefre/svn/trunk/voxgratia/OpalTester/src;-I/home/heefre/svn/trunk/voxgratia/OpalTester/build/src;-I/usr/local/Trolltech/Qt-4.2.0/include;-I/usr/local/Trolltech/Qt-4.2.0/include/QtGui;-I/usr/local/Trolltech/Qt-4.2.0/include/QtCore;-I/usr/local/Trolltech/Qt-4.2.0/include/QtDBus;;;-DP_USE_PRAGMA;-D_REENTRANT;;;;;-DPTRACING;-Wall;-Werror;-DQT_GUI_LIB;-DQT_CORE_LIB -x c++-header -o /home/heefre/svn/trunk/voxgratia/OpalTester/build/src/std_includes.h.gch/.c++ /home/heefre/svn/trunk/voxgratia/OpalTester/src/std_includes.h Every argument is separated by a colon, hence the compilation fails Frederic Heem
