no f77 on gcc (x86_64-pc-linux-gnu-3.4.2)

Hi

I'm running gentoo on my dual opteron 248 machine. I've installed it from stage 3 and gcc x86_64-pc-linux-gnu-3.4.2 was installed by default.
Even though I had "fortran" and "f77" on USE, aparentely I don't have f77 running.
'gcc -v'shows ammong other things: "--enable-languages=c,c++"

I've tryed to emerge gcc using 'USE="fortran f77" emerge gcc' and it installed gcc x86_64-pc-linux-gnu-3.4.3 which has f77 but no cpp (--enable-languages=c,f77) !!!!

I don't have a clue about what I have to do to get gcc to compile c, c++ and fortran.

Part of the purpuse of all this is to try to emerge R, which aparentely doesn't work with f2c, wich I already installed. From my understanding of it R needs all three compilers to work.

Can anyone help me out with this?

Cheers

Sounds like a bug to me. What's your output on emerge -pv gcc?

This is the output of emerge -pv gcc:

These are the packages that I would merge, in order:

Check the meaning of the USE flag nocxx (I hate these turned around flags, but nonetheless)

The price you pay for stupidity is humiliation...!

I was actually aware of the existence of the nocxx flag and its function (!?). I was however so certain that I hadnt checked it that I didnt bother to have a look at it, but there it was in USE on my make.conf. Another lesson learned the hard way! I removed nocxx from my USE and re-emerged gcc and voila:
--enable-languages=c,c++,f77

anyway, thanks for lokking at this.

It seems you've solved your problem. For the record, I installed R a month ago, no problems, after using USE-flag g77 (not f77). Upgraded to R 2.0.0 last night, and it all works beautifully.
