Re: gfortran

It *is* picking up gcc48.

It's not picking up gcc49. If only gcc49 is installed, it overlooks it and starts building gcc48 as a dependency.

If I install gcc48, it builds fine.

According to the message, either one should work:

=> Full dependency gcc48>=4.8: NOT found

I wonder why it is not picking up gcc48,

I've committed a requested change by Rin today to allow use of
GFORTRAN_VERSION=5 for example so it will pick up lang/gcc5.

Should GCC 4.9 alone not satisfy the requirement?

On my NetBSD 7 box, after adding PKGSRC_FORTRAN=gfortran to /etc/mk.conf:

That's not the point. The point is that all the alternative packages
like gcc49 etc are much more heavy by including things like the Java
backend. You can easily select a different implementation, but for
casual users, it is way too heavy.
For the record: I prefer something that’s heavy to something that does not compile at all. I submitted a PR a while ago where I tried to install some package on Linux, and it tried and failed to build g95. gfortran worked.

If a user does a bootstrap, then bmake package-install and gets a failed build until they manually configure the right fortran compiler (something that they most likely do not care about), then that’s a terrible experience.

If g95 is a good default for some platforms and not a good one for others: perhaps we can have a default that’s set in platform Makefiles?

Or, perhaps a USE_GFORTRAN variable in mk.conf, to let the user indicate
that gfortran should be used for all package builds?
You can already select a different fortran backend with PKGSRC_FORTRAN.
