Hi Ulf - Your directory listings look OK. Ideally, you'd actually use
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
as the Python files install location since that's the normal for MacPorts.
But, using /opt/local/lib/python2.7/site-packages is OK and an easy default.
Both should be in the default PYTHONPATH; you can see this via the command
{{{
python -c "import sys; print sys.path"
}}}
So, you should not have to set PYTHONPATH to anything special for this install.
If you have Python files installed elsewhere, you might still need it for
those files.
The "otool" listing for the RDS library:
{{{
> libgnuradio-rds.dylib:
libgnuradio-rds.dylib (compatibility version 0.0.0, current version
0.0.0)
}}}
is fine since nobody is going to be linking against it. Ideally, this first
entry would be the actual path/name combination
("/opt/local/lib/libgnuradio-rds.dylib"), but since it won't be used for
anything else it doesn't really matter. If you want to correct it, you can do
so via:
{{{
install_name_tool -id /opt/local/lib/libgnuradio-rds.dylib libgnuradio-rds.dylib
}}}
If you do the "otool" command on "_rds_swig.so", I think you'll find that it
contains:
{{{
_rds_swig.so (compatibility version 0.0.0, current version 0.0.0)
libgnuradio-rds.dylib (compatibility version 0.0.0, current version
0.0.0)
}}}
and this is where the issue is because the dylib cannot be found since DYLD
does not know where to look for it (DYLD can do a lot of things, but it does
-not- do arbitrary searches, generally, very well). Again, the actual path to
the .so is not important since this library ("shared object") will never be
linked to, just used by Python.
You can change this incorrect linkage via:
{{{
install_name_tool -change libgnuradio-rds.dylib
/opt/local/lib/libgnuradio-rds.dylib _rds_swig.so
}}}
and then Python should be able to load RDS correctly.
Hope this helps! - MLD
