Greetings all
I need to complie la.c (available in grass source code) in order to user LAPACK/BLAS libs
To do so, I saw that there is a makefile at \lib\gmath\ and I copied my gmath folder to my GRASS installation lib folder (c:/grass6/lib/gmath) in order to compile la.c
I used the following command:
gcc -c c:/la.c -I c:/grass/include
But nothing happened. has anyone tried to compile la.c (from gmath) in order to have access do LAPACK/BLAS libs in Windows? Or is it necessary to firtst first install LAPACK/BLAS libs from their website?
Thanks
Best regards,
Antonio R.

You don't need to copy anything.
However, you do need to ensure that:
1. The macros HAVE_LIBLAPACK, HAVE_LIBBLAS and HAVE_G2C_H are defined
in <grass/config.h>, otherwise la.c will compile to an empty object
file (one which contains no code).
2. The variables LAPACKLIB and BLASLIB are defined in
include/Make/Platform.make.
3. You have the <g2c.h> header (which defines the fortran types in
terms of C types), and suitable versions of the BLAS and LAPACK
libraries (where "suitable" means that the implementations match the
prototypes in <grass/blas.h> and <grass/lapack.h>.
