Moreover I advise you to read (even fast read) the documentation "man cmake" or "http://www.cmake.org/HTML/Documentation.html ". >From my experience with different collegue/friend "standalone" startup time with CMake is from 1 to 3 days where you find yourself "lost".

Seems you need to link with OpenGL. Try add the following to FIND_PACKAGE(OpenGL) IF (OPENGL_FOUND) MESSAGE(STATUS "Looking for OpenGL - found : ${OPENGL_gl_LIBRARY}") GET_FILENAME_COMPONENT(GLPATH ${OPENGL_gl_LIBRARY} PATH) LINK_DIRECTORIES(${GLPATH}) ELSE (OPENGL_FOUND) MESSAGE(STATUS "Looking for OpenGL - not found") ENDIF (OPENGL_FOUND) > > SET(Libraries fltk_images fltk_gl fltk arcball vecmat) > > SET(CurrentExe "TopMod") > FILE(GLOB SRC *.cc) > ADD_EXECUTABLE(${CurrentExe} ${SRC}) > TARGET_LINK_LIBRARIES(${CurrentExe} ${Libraries}) ADD GL library TARGET_LINK_LIBRARIES(${CurrentExe} ${OPENGL_gl_LIBRARY}) -- Erk _______________________________________________ CMake mailing list [email protected] http://www.cmake.org/mailman/listinfo/cmake
That code seemed to work for OpenGL, thanks. I am still getting some unresolved symbols, but none that have anything to do with OpenGL: /usr/bin/ld: Undefined symbols: _ClipRect _GetPort _GetWindowPort _SetPort _SetRect _GetWindowPortBounds _AECountItems _AECreateDesc _AEDisposeDesc _AEGetNthPtr _AEGetParamDesc searching for these terms on google always show me something that is Apple specific, and I found one old mailing list post about how CMake thinks I'm not compiling on a OS X anymore, and that I need to trick it into changing the compiler. I checked out my CMakeCache.txt file in my project directory, and I found these lines: //C compiler. CMAKE_C_COMPILER:FILEPATH=/usr/bin/gcc //CXX compiler. CMAKE_CXX_COMPILER:FILEPATH=/usr/bin/c++ I'm not sure if the CXX compiler is correct, or if it should be g++. I tried changing it there but it didn't go anything. Any ideas? thanks for the help, dave
