Have you tried to use ldd against the _libfoo.so to check if it is
able to get all the libraries it needs?

I've tried with ldd and the library aren't loaded. I don't use my *.i
interface so is quite difficult modify it (realy, the libraru is
supplied with make).

Any suggests?

Re: __stack_chk_fai l_local

The ldd should point you to the library which is not loaded.

Maybe the library you need is not in one of the normal locations in
your Linux/Unix path.

Normally, the linker looks for library under /lib and /usr/lib, and
maybe other paths specified in /etc/ld.so.conf

If you know the library is installed in your system, you can force the
linker to look for it, either modifying your /etc/ld.so.conf (better
if you know what you're doing, however) or, just setting the
LD_LIBRARY_PATH variable:

export LD_LIBRARY_PATH =/some/non/standard/lib/dir/

python -c "import foo"

Another possibility, which you can check googling a little, is that
you've two different versions of the libarary around your system, and
that you're loading the wrong one (i.e., python is looking at the
wrong one)

again, setting the LD_LIBRARY_PATH should help

Marco
