Error linking with libgfortran version (pardiso and lapack libs)

[fcostela <francisco dot costela at gmail dot com>]

Hi all,

I am trying to compile a program that requires both LAPACK and Pardiso
libraries on a Centos 4.5 x86_64 using gcc/gfortran. I am linking with the
file libpardiso400_GNU430_IA64.so that was compiled with gcc/gfortran 4.3. 
I compiled LAPACK 3.2.1 using my current gfortran version 4.1.2 on my Centos
(I could not update it to 4.2 or higher).

However, when I compiled I got this error:
/root/pardisolib/libpardiso400_GNU430_IA64.so: undefined reference to
`_gfortran_os_error'

I checked that my libgfortran version did not include that reference. Then I
downloaded newer gfortran versions (4.3.1) to link with libgfortran.so.3

This solved the problem about _gfortran_os_error but I got new errors
concerning the LAPACK lib:
/root/lapack-3.2.1/lapack_LINUX.a(dlamch.o)(.text+0xb04): En la funciÃn
`dlamc2_':
: undefined reference to `_gfortran_pow_r8_i4'
/root/lapack-3.2.1/lapack_LINUX.a(ilaenv.o)(.text+0x7a): En la funciÃn
`ilaenv_':
: undefined reference to `_gfortran_copy_string'

These two functions are not included in libgfortran.so.3. I found that the
right version of gfortran that might solve both errors is gfortran.4.2.3
(libgfortran.so.2). However I have not been able to find it for Centos
x86_64. It looks like there is no libgfortran.so.2 compatible for this
machine (or I could not find it!)

Any idea about how to link both libs together? It would be more than
appreciated.

Thanks for the help.

Regards,

Francisco
