gfortran [solved]

Hi,

I need to compile some Fortran 90 code, and was wondering what the best way to do that would be (preferably without borking my system).

Is it safe to install gcc 4 (which includes gfortran?) - it has a weird keyword, and seems to depend on unstable libraries. I would not want to use gcc 4 for the system, only for the fortran code.

What's the best way to do this?

Thanks,

_Max_

you could install gcc-4 in a chroot.
AFAIK - you have to install dev-libs/mpfr before gmp, which "USE=fortran emerge gcc" calls

gcc-4 also seems to depend on an unstable version of binutils. If I put all the appropriate packages/ keywords into package.keywords, emerge -pv \>gcc-4 seems to want to upgrade binutils (which I would rather not).

So how do I go about installing gcc-4 in a chroot? By hand, or is there now some feature in portage that will make this easy?

Were I you, I would consider installing a binary.

Yes, yes, yes... Just what I needed - thank you!

Pure genius.

GNU Fortran is not in a usable state.

I suggest you download the free trial of Intel Fortran.

Thanks for pointing that out. I installed ifc 7 as well, and now have g95, gfortran, and ifc 7. I guess the intel is likely to be the most reliable. Let's see then...
