--- Comment #25 from anlauf at gcc dot gnu.org --- (In reply to Jürgen Reuter from comment #24) > Here is a first reproducer without the need for OCaml, unfortunately a bit > too big to be uploaded, here is the link: > https://www.desy.de/~reuter/downloads/repro001.tar.xz > the tarball contains Fortran files that compile to two binaries, ./whizard > and ./whizard_check. Unfortunately, there is no main.f90, which is needed to build whizard. The Makefile needs to be modified to take into account that pythia.f needs preprocessing, e.g.: %.o: %.f $(FC) $(FCFLAGS) -c $< -cpp Furthermore, one needs to compile serially; parallel make does not seem to be supported. Can you please provide the missing file?
