I wonder what library you recompiled locally using pgi, if not the blas
lapack. I only had to link gsl and fftw (both c libraries I guess).
Futhermore I didn't have any problems linking gcc created c object (at
least not at the linking phase), anyway I compiled octopus again using
pgcc (that bytheway doesn't like the c++ way to put comments // and I had
to substitute with /* */) and nothing changed.
I also linked the acml instead of blas/lapack, but again this was not the
Maybe something that has changed between 1.4 and 1.99 makes the
latter not working.
