Subject: Using libpq without LD_LIBRARY_PATH

Greetings,
I am trying to get a simple C program to compile and run without having to
define the LD_LIBRARY_PATH environment variable. First I tried this:
gcc -o test -I/usr/local/pgsql/include -L/usr/local/pgsql/lib -lpq test.c
With LD_LIBRARY_PATH defined the program runs fine, without LD_LIBRARY_PATH
defined I get this error:
ld.so failed: Can't find shared library "libpq.so.2.0"
So, I changed my compiler like to this:
gcc -o test -I/usr/local/pgsql/include test.c /usr/local/pgsql/lib/libpq.a
This produced a linker error like this:
fe-auth.o: Undefined symbol `_crypt' referenced from text segment
*** Error code 1
So, I added -lcrypt to the whole mess, like this:
gcc -o test -I/usr/local/pgsql/include -lcrypt test.c
/usr/local/pgsql/lib/libpq.a
Then I get the following warning:
ld: symbol __GLOBAL_OFFSET_TABLE_ remains undefined
Where does all this stop? Can I static link with libpq? If so, how is it
done? As a last ditch effort I added symbolic links in my /usr/local/lib
directory to libpq.a, libpq.so and libpq.so.2, and compiled like this:
gcc -o test -I/usr/local/pgsql/include -lpq test.c
This compiled okay, but when I run the program I get this warning:
/usr/libexec/ld.so: warning: /usr/local/lib/libpq.so.2: minor version -1
older than expected 0, using it anyway
Any insight would be greatly appreciated.
Thank you,
Matthew Hagerty
