ImportError: *.so: cannot open shared object file: No such file or directory
I want to use the function stats.norm.isf, but no matter how I try to import it I end up with the error "ImportError: <libname>.so: cannot open shared object file: No such file or directory". The .so files cited do exist in /usr/lib (as symbolic links to other .so files that also exist in that directory). From what I've read, that's where they're supposed to be - but I think the Python installation is in a nonstandard location. Is that the problem? How can I work around it? Is there some way I can stitch together pieces of Scipy code in my script to directly access stats.norm.isf functionality and bypass these problems? I'm running Scipy 0.8.0/Python 2.6.3 under Red Hat Enterprise Linux ES release 4 (Nahant Update 5) on a Dell PowerEdge 1950.

No it won't be possible if you cannot run (Fortran) extensions. norm.isf uses scipy.special, which uses _cephes. Josef

I believe RHEL 4 uses g77 as its default fortran compiler, so you have a custom gfortran build somewhere, am I right ? If so, you need to add the paths where libgfortran.so and liblapack.so are to the environment variable LD_LIBRARY_PATH. Given that scipy has been built (by someone else for you ?), you may want to ask them about it for the exact locations of those libraries. cheers, David
