New description:
The file <prefix>/include/kdemacros.h is apparently generated by the CMake
script <prefix>/share/apps/cmake/modules/FindKDE4Internal.cmake, where the
KDE build tries to establish the compiler environment. After my kdelibs4
@4.8.2_0 install, I found that no other libraries I compiled and built
with #include kdemacros.h could be linked to applications code (I have a
development version of KDE Games on Apple). The reason was that GCC
visibility of library classes and symbols was not available, because
kdemacros.h did not have !__KDE_HAVE_GCC_VISIBILITY defined.
Macports 2.0.4, XCode 4.2.1 and OSX 10.7.4 are giving me the symbolic link
/usr/bin/c++ -> llvm-g++-4.2 When I force definition of
!__KDE_HAVE_GCC_VISIBILITY in my CMakeLists.txt, everything compiles and
links OK and works fine. So I guess llvm-g++-4.2 is a GCC-like compiler,
but is not being recognised as such.
