Re: Problems linking to libpq - Mailing list pgsql-novice

Thanks for the sugestion, but no luck!

I tried the single line command you sugested :
> cc -I/usr/local/pgsql/include jim.c -L/usr/local/pgsql/lib -lpq -o jim
However, I got the same result.

I checked the directory /usr/local/pgsql/lib and libpq.so was there.
However it was a Symbolic Link to libpq.so.2.2
I copied libpq.so.2.2 to libpq.so but it made no difference.

I am running SCO Unix Version 3.2 release 5.0.5

I am using the standard SCO Unix Compiler which is called "cc".
