hi,
maybe Rob could answer better than me, BUT ... some little remarks below :

Hi,
I hope anyone can help me out on this. I posted this message just before the whole mac-pc+linux discussion, so it dissapeared pretty quick, but if there's someone out there that can solve my 'issue', I would be pleased.
I'm following Rob Canning's instructions for building pdp_pidip on osx2.8; http://www.robcanning.utvinternet.com/pidip-install-osx.html#installlibs but ran into the following problem when i try to install the Imagemagick. [before installing ImageMagick i edited the .info file with --enable shared]
ibtool: install: warning: relinking `libMagick++.la'

I think there's something wrong with the way the libs are linked. [or unable to link] and i found the following lines in the FAQ of gcc:
Dynamic linker is unable to find GCC libraries
This problem manifests itself by programs not finding shared libraries they depend on when the programs are started. Note this problem often manifests itself with failures in the libio/libstdc++ tests after configuring with |--enable-shared| and building GCC
so, they basically, "hum, this problem happens, that's interesting", but don't they give a way to fix it ??
[http://www.gnu.org/software/gcc/faq.html#rpath]
As a reaction on the Finklist i got the following answer:
As you've discovered, ImageMagick has trouble building shared libraries on Darwin/OS X. That's exactly why the package maintainer did *not* choose to include the --enable-shared flag in the .info file.
they also do this for Linux and there's absolutely no reason for that. considering that Rob managed to do that compilation on OSX, it seems to be a wrong choice on their side.
good luck, sevy
But; does anyone know how I can install imagemagick with --enable shared without getting in trouble? Sara
