Hi Martial,

The compiler call that issues an error about dgelss links with
/usr/local/lib/liblapack.a /usr/local/lib/libf77blas.a 
/usr/local/lib/libcblas.a,
which seems correct.

According to the lapack and blas libraries name, you are linking with ATLAS.
Please check the version of ATLAS that you are linking with.
The regular ATLAS library contains only a subset of LAPACK API in liblapack.a, thus may 
miss dgelss. As you are using TAUCS, my recommendation is to download TAUCS from 
www.cgal.org/download.html, which contains a full LAPACK library on Linux (and fixes for 
TAUCS).

Best regards,
