Alright, slowly but surely. I've checked out ld.so.conf and the libraries appear to be setup correctly. The output of ldconfig -v shows (among other things): /opt/pgsql/lib: libpq.so.2.1 -> libpq.so.2.1 * There is no entry for the generic libpq.so * libpq.so is a link to libpq.so.2.1 Is this potentially the problem? Are there solutions? Thanks for all of the help already. - Steve On Tue, 01 August 2000, jpenny@universal-fasteners.com wrote:

Well, I'm getting somewhere. The make and make install on the PoPymodule completed with no errors, but now in python the import PoPy returns the following:

Traceback (innermost last): File "<stdin>", line 1, in ? ImportError: /usr/lib/python1.5/site-packages/PoPymodule.so: undefined symbol: PQfsize

This is defined in libpq, so, it appears that PoPy is doing using libpq as a shared library. This makes sense. Now, you know where libpq lives. edit (as root) /etc/ld.so.conf. Add the path to the library as the last line in this file. Then run ldconfig.

You might want to man ld.so and man ldconfig before you do this. This is not the kind of info to take on blind trust.

This is from the PoPy-1.2.1 tarball.

On another note, ZPyGreSQLDA appears to be up and running.

Thanks for all of the help.

Folks -

I could use a hand here - I'm trying to compile the PoPy module for python so I can use the ZPoPyDA to connect to my PostgreSQL database.

I keep getting the same compile error -

gcc - shared PoPymodule.o -lpq -o PoPymodule.so /usr/i486-suse-linux/bin/ld: cannot find -lpq

I have compiled other binaries on this machine, including Zope 2.2. Python runs fine, I just don't know enough about ld to understand the error. (I get the same error trying to compile ZPyGreSQLDA.

This message is saying that the postgres library libpq cannot be found by the linker (postgres was formerly called PostQuel, hence pq). Not having Suse, which I have heard has somewhat unusual layout, I cannot tell you for sure what to do...

but try find / -name "libpq*"

THis should find any libpq's on your system

Then if libpq is in /usr/lib/foo, do export LD_LIBRARY_PATH=/usr/lib/foo gcc - shared PoPymodule.o -lpq -o PoPymodule.so

...

Any pointers would be greatly appreciated.
