Hi, I have submitted a patch that needs to be modified to define _GNU_SOURCE for definitions of various glibc functions, like get_current_dir_name, declared in unistd.h if _USE_GNU is defined. __USE_GNU is defined by using the feature macro _GNU_SOURCE.
Not declaring get_current_dir_name creates problem for 64-bit architectures: warning: implicit declaration of function ‘get_current_dir_name’ [-Wimplicit-function-declaration] warning: assignment makes pointer from integer without a cast [enabled by default] Potential problems can arise see: http://wiki.debian.org/ImplicitPointerConversions Is the following construct OK? #ifdef __GNUC__ #define _GNU_SOURCE #endif ... #include <unistd.h> ... #ifdef __GLIBC__ new_path = get_current_dir_name(); ... #endif Testing against __GLIBC__ does not work since no libc header files have yet been included, leading to __GLIBC__ undefined. An alternate solution would be to use __GNU__ for both conditions, but that would make the patch Hurd only (do we want that?) -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
