Lapack/blas and Gotoblas

[Ben Tay]

Hi,

The result I get for lapack is

/usr/lib/liblapack.a  /usr/lib/liblapack.so  /usr/lib/liblapack.so.3
/usr/lib/liblapack.so.3.0  /usr/lib/liblapack.so.3.0.3

but for blas, there's no match. However, my school's tutorial said lapack
and blas can be used with the option -llapack -lblas.

Is there some other directory where they are usually install?

I'm wondering if I can use lapack + gotoblas together? I tried to specify
the libraries but ./configure failed.

Thank you.
