Trouble with gsl on install

[Steve Piccolo]

Hi there,

I'm trying to get mlpy installed on my Linux (RedHat 4, 64 bit)
servers. I've installed numpy, and that seems to be working fine. I've
installed gsl 1.14 and didn't seem to get any errors. I've also
installed mlpy (latest version) without any error messages. But when I
go to the Python prompt and type import mlpy, it gives me the
following error message:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.6/site-packages/mlpy/__init__.py", line
29, in <module>
from _dwt import *
ImportError: /usr/local/lib/python2.6/site-packages/mlpy/_dwt.so:
undefined symbol: gsl_wavelet_bspline

I'm not super familiar with Linux, so I'm not sure what to do. I know
that my gsl header files are in /usr/local/include/gsl and I think my
gsl shared object files are in /usr/lib64.

Any help would be greatly appreciated.

Thanks,
-Steve

Dear Steve,
probably you should set the LD_LIBRARY_PATH environment variable.
Open a shell and try the following:

$ export LD_LIBRARY_PATH=/path-to-shared-libs:$LD_LIBRARY_PATH
(probably /usr/lib64)

then

$ python
>>> import mlpy

You can you can make it permanent editing the .bashrc file.

That doesn't seem to have done the trick. I also tried pointing LD_LIBRARY_PATH to /usr/local/lib/gsl, which is where the gsl_wavelet header file is, but that didn't work either. Do I need to reinstall MLPY with this environment variable set? Any other ideas?

Steve,
try
$ ls /usr/local/lib/gsl | grep gsl

and show me the result.

LD_LIBRARY_PATH should point to the directory that contains the shared
object files (libgslcblas.so and libgsl.so).

These .so files were in /usr/local/lib (not in a gsl sub-directory). When I pointed LD_LIBRARY_PATH to /usr/local/lib, it worked.

Thanks!

P.S. Nice library!
