[oe] fortran and octave

[Alain2210]

Hello,

I would like to bitbake octave for org.openembedded.dev.
But octave needs fortran ou f2c.
It seems that fortran has been remove from gcc-cross_4.1.2.bb (or perhaps
before).
So I have tried to
1) add fortran in gcc-cross_4.1.2.bb but I get an error.
2) compile octave with f2c without success. (even with the f2c of the host)

So what is the good way to compile octave and/or fortran and/or f2c ?

Thanks,

Alain
