add OCE to DYLD_LIBRARY_PATH [ perhaps osx specific? ]

[jf---]

/Library/OCE/0.5.0/env.sh is a really useful script.
However, you still need to set the DYLD_LIBRARY_PATH for the libs to be found.
The following line accomplishes this on OSX.
It would be useful to have all nessecities for loading OCE in a single shell script, this way you only have to add
source /Library/OCE/0.5.0/env.sh in your ~/.bash_profile and be on your way

# make sure that the lib can be loaded
platform=`uname`
if [ $platform = "Darwin" ];
    then export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:$CASROOT/lib
fi;

On Linux, this env.sh script is useless, it would be nice if OSX users do not need it too. In fact, I kept it in the distribution only because some OCC-based applications may rely on these environment variables, but I would really like to get rid of this script.

This issue has been discussed on the mailing list months ago, see this thread (search for discussions about RPATH):
http://groups.google.com/group/oce-dev/browse_thread/thread/384bdf24ba811443

We (well, you OSX owners ;)) have to figure out how to make RPATH work out-of-the-box.

hello Denis,

I fully agree with you, we should be using RPATH since it would make our
lives a lot easier.
Linking with absolute paths is silly, of course...

Though isn't it a good courtesy to keep the env.sh?
In the sense that it provides a reference to OCC env vars.
