I know this is confusing. Giving you an example did not work. These are your requirements:
(try requirement 1a first)
1. All machines need to have exactly the pathnames to libraries
1a: Or all binaries have to know how to find the libraries
2. The actual names you set up have to exist everywhere.


You achieve 1a a single way:
LD_LIBRARY_PATH variable that shows how to find the library you want. This has to be in the environment variable set up for any user that runs the code: .profile, .bashrc, etc.

Example LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/path/to/library:${LD_LIBRARY_PATH}

"/path/to/library" is an example do not use it.

I can not know which if that jumble of output for libfunctorxxxxxx is where the correct library is. I AM GUESSING.

You will select the path that exists on the machine the process runs on
if
Code:
/export/build/nwwls/devspace/cm/delivered/prospect/prospect_core/Patches/8.0.7/P6/backup/pm/lib/ln/rwav/libfunctor2312d10g.so

exists:
Code:
export LD_LIBRARY_PATH=/export/build/nwwls/devspace/cm/delivered/prospect/prospect_core/Patches/8.0.7/P6/backup/pm/lib/ln/rwav/:${LD_LIBRARY_PATH}

if
Code:
/u04/net/rtp-netapp1/vol/build/nwwls/devspace/cm/delivered/MIDDLEWARE/middleware_cpp/prospect_core/8.0.7.10.01/server/pm/lib/tp/libfunctor2312d10g.so

then
Code:
export LD_LIBRARY_PATH=/u04/net/rtp-netapp1/vol/build/nwwls/devspace/cm/delivered/MIDDLEWARE/middleware_cpp/prospect_core/8.0.7.10.01/server/pm/lib/tp/:${LD_LIBRARY_PATH}

You do this on all 3 machines. You validate this by setting LD_LIBRARY_PATH, and executing the command
Code:
ldd example_program_name

where example_program_name is the name of your compiled code file
Keep twiddling the LD_LIBRARY_PATH until all libraries show in the ldd output.




You achieve #1 two possible ways
Way #1. Add symbolic links as paths on the production box to match development
-- this requires no change in compilation

Way #2: Add symbolic links (extra set of paths to libraries) on development, AND
change the link statement to follow the new symbolic path.
-- requires that you change compilation -- you have two make files

gsl-config - script to get version number and compiler flags of the installed GSL library SYNOPSIS
gsl-config [--prefix] [--version] [--libs] [--libs-without-cblas] [--cflags] DESCRIPTION
gsl-config is a tool that is used to configure to determine the compiler and linker flags that should be used to compile and link programs that use GSL. It is also used internally to the .m4 macros for GNU autoconf that are included with GSL. OPTIONS
gsl-config accepts the following options: --version Print the currently installed version of GSL on the standard output. --libs Print the linker flags that are necessary to link a GSL program, with cblas --libs-without-cblas Print the linker flags that are necessary to link a GSL program, without cblas --cflags Print the compiler flags that are necessary to compile a GSL program. --prefix Show the GSL installation prefix.
