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.

#34605: kdelibs4 @4.8.2_0 __KDE_HAVE_GCC_VISIBILITY not defined in <prefix>/include/kdemacros.h --------------------------------+------------------------------------------- Reporter: iandw.au@… | Owner: sharky@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.0.4 Keywords: | Port: kdelibs4 --------------------------------+------------------------------------------- Comment(by iandw.au@…): Looking at the CMake output for kdelibs4 @4.8.2_0, Macports is using the clang compiler to build kdelibs4 @4.8.2_0 and other ports that depend on it, such as kdegames4 @4.8.2_0. kdelibs4 configures its CMake macros accordingly, but they do not necessarily work when they encounter a different compiler. When I compile my own code with clang (KDE Games' SVN trunk and my contributions), everything works fine. However, OS X on my machine is configured with /usr/bin/c++ linked to a different compiler --- llvm-g++-4.2 --- and the KDE macros fail when I use that compiler, leading to linker errors. I have also written about this on https://bugs.kde.org/show_bug.cgi?id=300429 -- Ticket URL: <https://trac.macports.org/ticket/34605#comment:6> MacPorts <http://www.macports.org/> Ports system for Mac OS
