Yes, LD_LIBRARY_PATH would need to include the path at run time to the
Intel compiler library, including libcprts, same as when you run the
compiler, unless you linked -static. Normally, we would not build a lam
requiring this library, as the default for Intel icc 8.x is to use
libstdc++ (if present at installation on a .rpm supporting distro) rather
than libcprts. We use g++ rather than icc anyway, unless we know we have
C/C++ code which depends on icc for performance. If you link with Intel
Fortran, non-static, you will need that library path, but normally not for
STL support. There is no problem using g++ (in the normal ranges) together
with Intel Fortran.
If you start a dynamic linked lam without LD_LIBRARY_PATH set correctly,
you may have to lamhalt or kill lamd, set the correct PATH, and
lamboot. When running on the x86-64 OS, you must have the consistent
version of PATH and LD_LIBRARY_PATH, as there is nothing automatic to take
care of getting the proper version (32- vs 64-bit) of either lam or the
libraries. Sorry if "slackware 10 pc" carries more information than it
appears.
