Thank you John and William for the replies! @John: I downloaded the Fortran files from http://www.netlib.org/lapack/double/ <http://www.netlib.org/lapack/double/> (the link "dgesv.f plus dependencies"). In file dgesv.f the subroutine is declared as
SUBROUTINE DGESV( N, NRHS, A, LDA, IPIV, B, LDB, INFO ) with capital letters. @William: after looking for a while for a solution I discovered that R had "embedded" all the things I needed, so I just got rid of F77_NAME/CALL in my C code and simply called dgesv_ as declared in Lapack.h (adding as you suggested #include <R_ext/Lapack.h> in the preamble). So I did not changed the previous declarations of DGESV in my C file to lower case. On the one hand, it seemed (and seems) to me quite odd that my old code did not work and I would like to know why, even if it not a priority anymore. On the other hand, I am happy to have found a new, and, I suppose, more "R-package" oriented way, to use Fortran's linear algebra routines in my C code. N.
