I'm having trouble installing lapack & blas & making it work on my dual
P4 processor LINUX WS. I just want to learn how to use the dual
processors on the one machine for the time being & all I'm doing is
solving a large complex system of eqs. Everything seems to build OK.
For example, I can untar BLAS & LAPACK, & successfully build & test
blas_LINUX.a, then copy it into the top lapack directory (lapack-3.1.1)
& successfully build & test lapack_LINUX.a. However, when I build (with
g77) my fortran application containing a call to lapack's cgesv, the
linker cannot find cgesv_, no matter what lib directives I use or the
order I give them in the Makefile. Also, do I need to buy a 3rd party
OMP package like Portland Group because g77 can never see the OPM
directives in the fortran comments if I want to parallelize my own
code? Are both problems related?
