Thread: libpq

Hi!

Compiling the following returns me - executing the result.cgi - the
error:
./result.cgi: can't load library 'libpq.so.2'

gcc -lpq -I/usr/include/mysql -I/usr/local/pgsql/include
-L/usr/local/pgsql/lib -L/usr/lib/mysql program.c
-o result.cgi -Wall -DUNIX -lmysqlclient -lm

All files are at its places. I use PostgreSQL 7.1.3.

What I'm doing wrong?

Thanx
Steve

You didn't mention what platform you're on.

You've not told the dynamic loader to have the directory where you've put
libpq.so.2 in its search path. Set an appropriate LD_LIBRARY_PATH, or (at
least on GNU/Linux) update /etc/ld.so.conf and rerun "ldconfig".

HTH,
