Hi, When macports compiles and links an application are the shared library paths hard coded into the binary? I s this the typical behaviour on OS X? Best Regards, Simon.

When a binary file is compiled, during the configuration step there is usually an option that determines the shard library path. If you wanted to change the location of shared libraries you'd have to re-run the configure script with the new library directory and then recompile the software.

Hi, Thanks for the reply. Maybe I misunderstand but I though, on Linux, the run-time linker had a set of search paths to look for shared libraries? Best Regards, Simon. On 14 Jan 2008, at 13:37, Matrix Mole wrote:

I always thought that there was some kind of lib directory option in the ./configure script that could be set, if not it'd default (usually to /usr/local or whatever had been coded by the programmer).

Unfortunately, my programming experience and knowledge is extremely limited, and I might be mistaking shared libraries with runtime dependent libraries. I'm hoping if I'm incorrect then someone can show me where, but this is how I've understood it for a while now.

I guess Simon is talking about ld.conf that exists on Linux, and for which there is no Mac OS X equivalent.
