Watch the elog messages. It will tell you at some point to either enable
fortran or emerge some other package that I forget the name of. That one
package pulled several dependencies on my rig. YMMV.
Well, as I said in another post, I do have -fortan in my make.conf and
there are no problems. I do not have programs installed that need a
fortran compiler. And I do not have kde-meta installed; that's a waste
of resources. I only install what I actually need.
You have no programs, that *need* fortran, but it could well be, that you have
programs installed, that perform better when compiled with a fortran compiler.
I think of sci-libs/fftw here as an example. It's used by programs like
blender, imagemagick and maybe some others. The developers of said library use
fortran, because they benchmarked it. If you disable fortran, you use the
slower C fallback solution. If you disable fftw in those packages, you get a
slower implementation too afaik.
After all, gentoo is a source based distribution. We all already have a couple
of languages installed. There's a C compiler a standard user will never use.
There's a C++ compiler only used by programmers. We all have them, only to
compile programs, that need them.
Why not enable fortran, even if it's only optional, to get the best of the
available implementations? In the end it's only one programming language more
installed on your system.
Because there is absolutely no clue in the USE descriptions that this is
the "best implementation" or whatever.
