Note: not a dup of #136425. After upgrading to gcc 4.1.1, I built octave without any problem. Then recently I noticed it was linked to libg2c which only existed in my gcc-3.4.5 dirs. I have now removed all older compilers from my system and now only have gcc-4.1.1. When I try to rebuild octave, I get the following: >>> Emerging (1 of 1) sci-mathematics/octave-2.1.73 to / >>> checking ebuild checksums ;-) >>> checking auxfile checksums ;-) >>> checking miscfile checksums ;-) >>> checking octave-2.1.73.tar.bz2 ;-) * You need one of these Fortran Compilers: gfortran g77 * Installed are: gfortran g77 >>> Unpacking source... >>> Unpacking octave-2.1.73.tar.bz2 to /var/tmp/portage/octave-2.1.73/work * Applying octave-2.1.73-gcc4.1-gentoo.patch ...

If you need support, post the topmost build error, and the call stack if relevant. But of course I don't have g77: gcc-4.1.1 only comes with gfortran. I'm guessing when I built octave before when I still had the old gcc-3.4.5 on my system it used g77 from gcc-3.4.5. Note: # g77 gcc-config error: g77 wrapper: Unable to determine executable. CTARGET=i686-pc-linux-gnu exec=g77 # gfortran i686-pc-linux-gnu-gfortran: no input files So either octave really needs g77 (I've heard some fortran stuff doesn't compile with gfortran), or this is a problem with gcc-config/fortran.eclass. Again, note this part from above: * You need one of these Fortran Compilers: gfortran g77 * Installed are: gfortran g77 Which is a little wierd because I do not have a g77 compiler.

One additional clarification: I stated that octave was linked to libg2c: that was apparently not correct because I rebuild lapack and blas (they were previously built with gcc-3.4.5) and now my (previously installed) octave works fine.
Interestingly, this doesn't show up on my laptop which is using gcc-config 1.3.13-r2 (hasn't been upgraded to eselect-compiler yet): * You need one of these Fortran Compilers: gfortran g77 * Installed are: gfortran back on my desktoo system I noticed the following lines in /etc/eselect: compiler/i686-pc-linux-gnu-3.4.4.conf: alias_gfortran=g77 compiler/i686-pc-linux-gnu-4.1.0.conf: alias_g77=gfortran compiler/i686-pc-linux-gnu-3.4.5.conf: alias_gfortran=g77 But gcc-4.1.1 doesn't have such a line. I also noted that i have a /usr/bin/g77 on my desktop that no package seems to own! I deleted that file and now the fortran.eclass correctly notes that we only have gfortran.

I found all these files in /usr/bin with dates different from my newly rebuilt gcc-4.1.1: -rwxr-xr-x 1 root root 9100 May 27 16:05 g++32 -rwxr-xr-x 1 root root 15448 May 27 16:04 g77 -rwxr-xr-x 1 root root 9100 May 27 16:05 gcc32 -rwxr-xr-x 1 root root 9100 May 27 16:05 i686-pc-linux-gnu-g++32 -rwxr-xr-x 1 root root 15448 May 27 16:04 i686-pc-linux-gnu-g77 -rwxr-xr-x 1 root root 9100 May 27 16:05 i686-pc-linux-gnu-gcc32 I moved them all away, did did my "eselect compiler set 1" and resource /etc/profile. Now it works. Closing "next-time-investigate-before-you-post-a-bug" ;-)
Look in /etc/eselect/compiler/ and remove every line from the files that says something like alias_gfortran=g77 and alias_g77=gfortran. They are extremely broken and gcc no longer installs them like this.
I added to /etc/compiler/i686-pc-linux-gnu-4.1.1.conf "alias_g77=gfortran" to the globals section and everything worked...
(In reply to comment #6) > I added to /etc/compiler/i686-pc-linux-gnu-4.1.1.conf "alias_g77=gfortran" to > the globals section and everything worked... CORRECTION: I added this line AND I executed "eselect compiler select 1" with 1 standing for gcc-4.1.1 and then everything worked fine.
If i do that: cd /usr/bin ln -s gfortran-4.1.1 gfortran ln -s gfortran g77 Working here, but i don't know if in the future have a problem with this. Someone know?
