I'm trying to build the latest gpc (gpc-20070904.tar.bz2) with Adriaan's patches on a Macintosh OS X 10.5.2. with Intel. I configure with ../gcc-4.1.2/configure --enable-languages=pascal,c --enable-threads=posix --prefix=/Developer/Pascal/gpc412 but the "make bootstrap" fails with Undefined symbols: "___sysctl", referenced from: ___enable_execute_stack in _enable_execute_stack_s.o ld: symbol(s) not found /usr/bin/libtool: internal link edit command failed make[3]: *** [libgcc_s.dylib] Error 1 make[2]: *** [libgcc.a] Error 2 make[1]: *** [stage1_build] Error 2 make: *** [bootstrap] Error 2 What am I missing?
