    I have a cross-platform application and I want to compile it on Mac OS X 10.4.11
    There are some functions for using load, and free external library and get its functions and they are defined for each platform by #if defined(_WIN32) || defined(_WIN64) and #elif defined(__Apple__).

    But there is errors like
    NEXT_ROOT environment variable ignored because -syslibroot specified
    Undefined symbols:
    .............../.../.../ppc/someIM.o reference to undefined _LibraryFree
    ... same as above for _LibraryGetFunc
    ... same as above for _LibraryOpen
    internal link edit command failed

    I specified MacOSX10.3.9.sdk for SDKROOT_ppc and MacOSX10.4u.sdk for SDKROOT_i386.

    Is there anyone guess what the problem is ?
