Hi all
I wonder what the policy/methodology is concerning compiler selection. I
perused the MacPorts guide but couldn't find anything. Am I right in the
assumption that MacPorts automatically comes with its own gcc compiler
suite and requires it to be present (I think I read something like that
somewhere in the FAQ)? If so, on which one can I rely to be there?
gcc32, gcc40/1/2 or apple-gcc40? just because the executable have all
different names...
My problem actually is that a port which I'm preparing requires gfortran
which doesn't come with Apple's system gcc but is in port:gcc42. I could
simply do "configure.fc ${prefix}/bin/gfortran-mp-4.2, but what if
someone has another gcc installed? I could depends_build on gcc42 but if
a gcc suite is required by MacPorts anyways I wouldn't like to impose
something which might install another compiler suite unnecessarily.
So, currently I do a hacky
set gfortran [lindex [lsort -decreasing [glob \
-type f "${prefix}/bin/gfortran*"]] 0]
configure.fc ${gfortran}
and hope to get the compiler with the highest version number. For my
installation this works, but I'm quite unhappy with it.
Does anyone know a better solution to that problem?
Thanks for the help
Michael
