i'm using a tru64 system. I tred to install a math tool, OOF, but it
needs LAPACK. So I installed a compaq software cxml which was said
including the lapack. But the math tool cant find "libblas", which is
supposed to be the library of BLAS.
anyone know how to solve this porblem? thanks a lot!

when you compile lapack, there is an option to turn on/off the blas. turn it
off.
or you can add -llibblas in your Makefile.

i get the lib file?

I installed a package(cxml) provided by Compaq. And all the tests in
LAPACK/BLAS were passsed. But when i run "sh ./configure" to configure
the math tool i want to install, it still can not find "libblas", following
is the code in the configure file to test blas. should i make any changes?
thanks!
...
AC_CACHE_SAVE
dnl Checks for libraries.
AC_ARG_WITH(blas,
[ --with-blas=-lblas Specify library (or libraries) for BLAS],

if test "x$withval" != "xno" ; then

what if you pass the full path of your libblas.a?

well, the problem is i cant find that libblas.a
the compaq software installed some "lapack-equivalent", dont know how it works.
sigh, the system is totally a mess, esp to me
even rpm cannot be installed, even for the package i download form tru64 website.

the problem is only it can't find the libs. 8-)
