Re: Problem building 64-bit gm2 on Solaris 11.3/sparc

Hello John,

ah - yes indeed - I've added:

 mcflex.o: mcflex.c m2/gm2-libs/gm2-libs-host.h
        $(CC) -I$(srcdir)/m2/mc -g -c $< -o $@   # remember that
mcReserved.h is copied into m2/mc

which builds on an x86_64 debian system - how does it fare on the sparc?

Gaius
