hi all,

I'm tring to compile grass-5.7.0 with blas (atlas-3.7.8) and lapack
(lapack-3.0) support.

from atlas-3.7.8 compilation I have:
drwxr-xr-x root/root usr/
drwxr-xr-x root/root usr/include/
-rw-r--r-- root/root usr/include/cblas.h
drwxr-xr-x root/root usr/lib/
-rw-r--r-- root/root usr/lib/libatlas.a
-rw-r--r-- root/root usr/lib/libcblas.a
-rw-r--r-- root/root usr/lib/libf77blas.a
-rw-r--r-- root/root usr/lib/libtstatlas.a

and from lapack-3.0 compilation:
drwxr-xr-x root/root usr/
drwxr-xr-x root/root usr/lib/
-rw-r--r-- root/root usr/lib/lapack_linux.a
lrwxrwxrwx root/root usr/lib/liblapack.a -> lapack_linux.a

those libraries are obviously perfect and they are succesfully utilized
from programs like octave-2.1.59 and R-2.0.0 .

This is my grass-5.7.0 configure :
./configure --prefix=$PKG/opt --exec-prefix=$PKG/opt \
    --enable-64bit-vis=no --with-cxx --with-fftw --with-proj \
    --with-motif --with-blas --with-lapack \
    --with-mysql=no --with-odbc=no --disable-nls \
    --with-opendwg --with-opendwg-includes=$ODA --with-opendwg-libs=$ODA

I succesfully compile grass but there is no support for blas/lapack.

First, the BLAS library has to be called libblas.* (i.e. it can be
linked using -lblas).

Second, I'm not sure whether anything can actually use BLAS/LAPACK at
present. If those libraries are enabled, some additional functions are
available in the gmath library. However, I'm not sure whether anything
actually uses those functions.
