Обсуждение: Library Error

I just installed PostgreSQL on a Linux machine and it seems to run fine.  However, I cannot do anything to it since I get the following error message everytime I run any program (except initdb, that worked):

psql: error in loading shared libraries: libpq.so.2.1: cannot open shared object
 file: No such file or directory

The file does exist in the /usr/local/pgsql/lib directory, I do have permissions for it, and I put lib in my path, yet it still complains.  Is there a .conf file parameter missing somewhere?  A configure param?

Any help would be appreciated.

I too have had the same problem.  Admittedly I haven't had
time to read too much about the finer points of installation, or
even administration for that matter.

I simple added /usr/local/pgslq/lib to my LD_LIBRARY_PATH and
that took care of it.

Add this to your environment:

LD_LIBRARY_PATH=/usr/local/pgsql/lib:$LD_LIBRARY_PATH

(lib doesnt need to be in $PATH, that's just for executables, this is a shared library)

You need to run ldconfig to tell the system where to find it.  (Read the
man page for detailed instructions.)

Alternatively, make sure that LD_LIBRARY_PATH includes /usr/local/pgsql/lib,
and is exported in your environment.
