gcc-4.2 setting for gfortran

[Miroslav ILIAS]

Dear all,

on our opteron machine we have this gfortran:

.gfortran --v
Using built-in specs.
Target: x86_64-unknown-linux-gnu
Configured with:
/home/tob/projects/gcc-4_2-branch/configure--enable-languages=c,fortran
--prefix=/projects/tob/gcc-4.2
Thread model: posix
gcc version 4.2.0 20070416 (prerelease)

When compiling a big program system (mix of fortran and C codes) on this server,
I got this error:

gfortran -g -fdefault-integer-8 -ff2c -fautomatic -fno-f2c -o

/home/tob/projects/gcc-4_2-branch/libgfortran/fmain.c:18: undefined reference to

On other server with this setting the compilation above works:

.gfortran-4.1 --v
Using built-in specs.
Target: x86_64-linux-gnu
Configured with: ../src/configure -v --enable-languages=c,c++,fortran,objc,obj-c
++,treelang --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/l
ib --without-included-gettext --enable-threads=posix --enable-nls --program-suff
ix=-4.1 --enable-__cxa_atexit --enable-clocale=gnu --enable-libstdcxx-debug --en
able-mpfr --enable-checking=release x86_64-linux-gnu
Thread model: posix
gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)


Could someone help me on how to properly install gcc/gfortran ? Thanks.
