Where does Python look for libraries?

[ACB]

I have been trying to get the gdmodule installed and have run into an issue.
When I import gd I get the following error.
[color=blue][color=green][color=darkred]
>>> import gd[/color][/color][/color]
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/local/lib/python2.3/site-packages/gd.py", line 10, in ?
import _gd
ImportError: /usr/local/lib/libgd.so.2: Undefined symbol "libiconv_o pen"

But, when I run
nm libiconv.so
in the directory with the iconv library I get an entry like this
00011fe0 T libiconv_open

so I know the functionality is there. So, my question. Does python have a
way to add search directories for locating libraries?

Thanks.

Python has sys.path
If you want to add dirs into your PYTHONPATH add them to sys.path

The OP seems to be asking about C libraries dynamically linked to extension
modules, not Python libraries.

No. You will have to read your OS's documentation on how to make sure
libiconv.so is in a location your dynamic linker will look for shared libraries.
If you are on Linux, then probably

$ man ld.so

will tell you the appropriate information.
