Hi, I'm trying to port the new gnustep libobjc2. When I compile it, I get the following warning:
clang -DTYPE_DEPENDENT_DISPATCH -DGNUSTEP -D__OBJC_RUNTIME_INTERNAL__=1 -D_XOPEN_SOURCE=500 -D__BSD_VISIBLE=1 -DNO_SELECTOR_MISMATCH_WARNINGS -g -O0 -fno-inline -O2 -pipe -g -O0 -std=gnu99 -fPIC -fexceptions -c block_to_imp.c -o block_to_imp.o block_to_imp.c:35:10: warning: implicit declaration of function 'asprintf' is invalid in C99 [-Wimplicit-function-declaration] if (0 > asprintf(&tmpPattern, "%s/objc_trampolinesXXXXXXXXXXX", tmp)) ^ 1 warning generated. usually this is just a missing header file, and man asprintf says, stdio.h should be included, but I checked and that's already the case. In stdio.h the declaration of asprintf function is surrounded with a #ifdef __BSD_VISIBLE But that's given on the command line, so I think clang should pick it up. Googling told me to check for _GNU_SOURCE too, but that's also given on the command line. So this may be a basic question, but I don't get it. Any other idea from someone? Sebastian
