LD has some default paths (like /lib and /usr/lib) hardcoded. On some systems, the linker is modified to add non standard paths (/opt/lib /sw/lib /usr/local/lib, /usr/X11R6/lib) to these default paths, and some systems don't do this. BSD typically doesn't. (and requires /usr/local/lib to be included) Darwin, as a BSD derivative, seems to follow this. I can only guess about the reasons, but two good ones are: - running contributed software unmodified (GPL is considered non-free from BSD perspective and "dangerous"). Unlikely since they do other mods, but maybe good enough to be a historical one. There was a lot of opposition to switching to the GNU toolchain in the past. - (the better IMHO) Non-core directories could be writable to a wider audience, leading to all kinds of trojan security dangers. This is also the reason why BSD separates /usr/lib and /usr/local/lib > Is there any documentation where this can be found? Is there a place > where I can put this info in the FPCWiki? More buildfaq work I think. But it is standard on *BSD and Unix in general (Solaris also has a few added paths, since the GNU toolchain is not globally installed). When I added this on my mac-mini I didn't even give a second thought. (-Fu issues) Odd. Do the Lazarus makefiles maybe disable fpc.cfg ? Try building with -OPT='-vt' or va and examine the (huge) output. _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
