I was compiling gcc-4.3.4.tar.bz2 package using gcc version 4.4.1, I think, but for example g++ was some older version. So I decided to compile package that included all compilers to get same version for all, and selected 4.3.4.

After the error message above I thought that I can anyway to install other parts of gcc package and made "make install" with success. But there is anyway some bug with the fortran part of the package. uname -a gives the following text "2.6.18.2-34-default #1 SMP Mon Nov 27 11:46:27 UTC 2006 i686 i686 i386 GNU/Linux" -- Summary: Make command failed with fortran when compiling source Product: gcc Version: 4.3.4 Status: UNCONFIRMED Severity: major Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: karvonen dot jorma at gmail dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41362
