Beginner: Trouble setting up LAPACK & BLAS with pgf90
Posted: Wed Jul 11, 2012 4:37 pmHello to who ever is reading this 
I am having trouble with getting LAPACK and BLAS to work. I have tried my best to search around the interweb for step by step install that I could tweak for my own. However, I am new to this install/building process with make files.
If this question is handled in an existing post i must have missed it or been to naive to understand what it was i was reading. If this is the case please let me know.
To start, I believe that I must create a make file specifically for the pgf90 compiler. So... next step model one of the make.inc.* files?

BLASLIB = ../../librefblas.a
LAPACKLIB = liblapack.a
TMGLIB = libtmglib.a
I am not sure what I should change and or not change with respect to the pgf90 compiler. I have searched around for a knowledge base to answer these questions as well, but alas I have not been succesful.
Any help will be appreciated greatly
