Hi, I just tried that, and I think I have been using the current default:
NicolasMacBook:~ nicos$ port installed cctools The following ports are currently installed: cctools @921_0+llvm70 (active) The reason I have been mentioning how old as might be is that the one provided by cctools returns version 1.38, which quite behind compared to the version provided by binutils, for example. /opt/local/bin/as -v Apple Inc version cctools-921, GNU assembler version 1.38 Cheers, Nicolas > On Jan 22, 2019, at 0:23, Chris Jones <jon...@hep.phy.cam.ac.uk> wrote: > > Hi, > > What exactly version (and variants) of cctools do you have installed ? > > Perhaps try force removing it, then reinstall, to make sure you are using the > current default variants. > > Chris > > On 21 Jan 2019, at 2:47 pm, Nicolas Pavillon <ni...@macports.org > <mailto:ni...@macports.org>> wrote: > >> Hi, >> >> I stumbled on some issues with the fortran compiler that I cannot really >> understand.
