 135 # The code below has been temporarily removed, because...
 136 # With GNUstep -make on any platform, when you compile a
 137 # framework, it is supported by creating a link like
 138 # Librairies/libMyFramework.dylib ->
 139 # Frameworks/MyFramework.framework/Versions/Current/libMyFramework.dylib, to
 140 # mitigate the fact that FSF GCC supports to link frameworks with the -frameworks
 141 # flag only on Darwin .
 142 # Well concerning library GNUstep -make on Darwin, the problem lies in the fact
 143 # the Darwin linker seems to be unable to link the library when you pass the
 144 # flag -lMyFramework to compile an application which depends on it, strangely it
 145 # links the framework directly.  You can see that with otool -L
 146 # Whatever/MyApplication.app/MyApplication which will output
 147 # MyFramework.framework/MyFramework and not libMyFramework.dylib .
 148 # So because a framework is linked when it is present even when you want to
 149 # link the equivalent library, the application will not find the framework when
 150 # you launch it with DYLD_FRAMEWORK_PATH empty. To correct that, we must
 151 # set DYLD_FRAMEWORK_PATH in any cases until the Darwin linker behaves correctly.
