Hi Simon, On MacOS X 10.3.9 the 'gc-gnulib' (or 'gc-des') module fails to build:
depbase=`echo gc-gnulib.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\ gcc -std=gnu99 -DHAVE_CONFIG_H -DEXEEXT=\"\" -DEXEEXT=\"\" -DNO_XMALLOC -DEXEEXT=\"\" -I. -I.. -I../intl -Wall -g -O2 -MT gc-gnulib.o -MD -MP -MF $depbase.Tpo -c -o gc-gnulib.o gc-gnulib.c &&\ mv -f $depbase.Tpo $depbase.Po In file included from gc-gnulib.c:65: des.h:62: error: conflicting types for `des_setkey' /usr/include/unistd.h:196: error: previous declaration of `des_setkey' make[3]: *** [gc-gnulib.o] Error 1 The declaration in /usr/include/unistd.h looks like this: int des_setkey(const char *key); which is clearly different from the one in gnulib's des.h: extern void des_setkey (des_ctx *ctx, const char * key); Bruno
