[Gmsh] Singular value decomposition requires LAPACK

[Vadivelan C]

Hi Dave,

Thanks for your quick reply. BTW, i have installed lapack, blas libraries
using yum. I have checked

[velan at scram ~]$ ls /usr/lib/{*lapack*,*blas.*}
-rw-r--r-- 1 root root 5.6M 2008-07-08 22:58 /usr/lib/liblapack.a
-rw-r--r-- 1 root root 483K 2008-07-08 22:58 /usr/lib/libblas.a
-rwxr-xr-x 1 root root 4.0M 2008-07-08 22:58 /usr/lib/liblapack.so.3.1.1

-rwxr-xr-x 1 root root 354K 2008-07-08 22:58 /usr/lib/libblas.so.3.1.1
-rwxr-xr-x 1 root root 221K 2008-09-16 13:25 /usr/lib/libgslcblas.so.0.0.0

liblapack.so.3.1.1
lrwxrwxrwx 1 root root   16 2009-06-02 11:21 /usr/lib/libblas.so ->
libblas.so.3.1.1

Which shows, lapack library was installed. During gmsh installation i have
done following steps

./configure --prefix=/home/soft/gmsh-2.3.1
--with-blas-lapack-prefix=/usr/lib/

But still i am getting those errors. Can you tell me how to find whether
lapack/blas libraries was configured during gmsh installation. I couldnt
find anything on config.status files.

Thanks
