Hi Everybody,
I am not sure if this is the right mailing list to ask
what I want to ask. Please direct me to the right place,
if there is a better list.
Close to a year ago, I wrote a C program using libpq package.
It took me a week to debug, but I got it compiled and I have
been using it regularly. The program is named pivot and compiled
on a Redhat linux (AMD 64-bit) machine with the command:
cc -I/pgsql/pgsql836/include -L/pgsql/pgsql836/lib -lpq -o pivot pivot.c
And I just tried recompiling it on that machine and it compiles without a
complaint. I now need to re-compile it on a Intel 32-bit machine running
centOS. When I issue the same command on the centOS machine, I get
complaint:
/usr/bin/ld: cannot find -lpq
collect2: ld returned 1 exit status
I thought that this meant that the shared library named libpq.so.bla
is missing. But to my surprise, I find libpq.so.4.1 in /usr/lib
directory. (There is also a symbolic link libpq.so.4 pointing at
libpq.so.4.1 in the same place.)
So, I don't know what the complaint is about.
Can someone please clue me in?
Thank you in advance.
Regards,
Tena Sakai
