LIBPATH: Setting library search paths

Under normal circumstances, you only need LIBPATH if shared libraries are located in different directories at run time rather than at compile time. To use LIBPATH, set it at run time to the names of any directories that contain required user libraries, plus /usr/lib:

   # Compile and link
   xlf95 -L/usr/lib/mydir1 -L/usr/lib/mydir2 -lmylib1 -lmylib2 test.f

   # When the libraries are in the same directories as at compile
   # time, the program finds them.
   a.out

   # If libmylib1.a and libmylib2.a are moved to /usr/lib/mydir3,
   # you must set the LIBPATH variable:
   export LIBPATH=/usr/lib/mydir3:/usr/lib
   a.out
