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
