Re: [trinity-devel] cmake debug help - amarok

All, In the following code from amarok/ConfigureChecks.cmake: # konqsidebarplugin.h if( WITH_KONQSIDEBAR ) tde_save( CMAKE_REQUIRED_DEFINITIONS CMAKE_REQUIRED_FLAGS CMAKE_REQUIRED_INCLUDES CMAKE_REQUIRED_LIBRARIES ) set( CMAKE_REQUIRED_DEFINITIONS ${TQT_CFLAGS_OTHER} ) set( CMAKE_REQUIRED_INCLUDES ${TDE_INCLUDE_DIR};${TQT_INCLUDE_DIRS};${CMAKE_INCLUDE_PATH} ) set( CMAKE_REQUIRED_FLAGS "-include tqt.h" ) set( CMAKE_REQUIRED_LIBRARIES -L${TQT_LIBRARY_DIRS} ${TQT_LIBRARIES} ) check_cxx_source_compiles(" #include <konqsidebarplugin.h> int main(int, char**) { return 0; } " HAVE_KONQSIDEBARPLUGIN_H ) tde_restore( CMAKE_REQUIRED_DEFINITIONS CMAKE_REQUIRED_FLAGS CMAKE_REQUIRED_INCLUDES CMAKE_REQUIRED_LIBRARIES ) if( NOT HAVE_KONQSIDEBARPLUGIN_H ) tde_message_fatal( "konqsidebarplugin.h are requested, but not found on your system" ) endif( ) endif( ) What is this code checking? check_cxx_source_compiles(" #include <konqsidebarplugin.h> int main(int, char**) { return 0; } " HAVE_KONQSIDEBARPLUGIN_H ) I can find the '#include <konqsidebarplugin.h>' bit in: amarok/src/konquisidebar/universalamarok.h, but what does the rest of the check_cxx_source_compiles look for? 'int main(int, char**) { return 0; }' isn't in the code: /chroot/david/build/src/amarok> grep -r 'int main(int, char\*\*)' * ConfigureChecks.cmake: int main(int, char**) { (void)new QGLWidget((QWidget*)0, \"qgl\"); return 0; } " ConfigureChecks.cmake: int main(int, char**) { return 0; } " It's nowhere else in the amarok code -- this is what is causing the konqsidebarplugin cmake failure. I can't explain why it isn't seen on Darrell's build -- we should have the same amarok code... That's why I need help understanding exactly what this check_cxx_source_compiles code is looking for.
