[fercaba]

Hi, i just install aparently succesfully lapack libreries.
But, when y try to compile and link with lapack i get the following errors:

Does anybody have an idea?

Thanks!

Just add the BLAS library -
make blaslib is the command
then make

Julie, it was not necessary to build the BLAS library. I had run "make all" and modified the makefile exchanging a comment on 2 lines.

# lib: lapacklib tmglib
lib: blaslib variants lapacklib tmglib

Originally the # was on the second line.

The BLAS library had been built, therefore, i had to add -lblas to compile the program, had only used -llapack

Another question, why the BLAS library is called librefblas by default instead of libblas as it mentioned in make.inc?

Thank you very much for everything

[admin]

We call it the Reference BLAS, because this is the reference implementation of the BLAS library.
This reference library won't give you any performance.
In order to get better performance you need to get an optimized BLAS library.
See http://www.netlib.org/blas/faq.html#5 for more info.
Hope it helps
