Please delete /usr/bin/i686-pc-linux-gnu-g77. gcc4 uses gfortran
Yes, but some apps use g77 explicitly (like lapack-3.0). What to do?
Encountered this bug when trying to emerge fftw on a fresh amd64 install with gcc-4.1.1 being the primary compiler. It apparently relies on explicitely calling g77. On the other hand, I also have an i686 laptop on which I use gcc-4.1.1 too and if I try using g77, the wrapper automagically call gfortran, which is not the case on my amd64 box. The latter gives me gcc-config error: g77 wrapper: Unable to determine executable. CTARGET=x86_64-pc-linux-gnu exec=g77 Would it be a bug in the eselect-compiler package, not installing wrappers correctly on every platform? PS. It it helps, both of my machines are ~arch
I can confirm this bug on a previously working ~x86 athlon-xp machine. This bug depends on the AC_PROG_F77 macro finding /usr/bin/g77 before /usr/bin/gfortran. This should not be a problem if g77 was correctly configured, but there obviously is an error. A workaround is to override the macro by doing echo 'export F77=/usr/bin/gfortran' >> /etc/portage/bashrc
The problem is that g77 used to be an alias to gfortran in the configs, but that was in error and was removed. Removing the alias still left the dangling wrapper. If you remove the wrapper or switch to 3.4 then back to 4.x (which removes the wrapper), you sould be fine.

bug #135688 can also cause the /usr/bin/{g77,gfortran} wrapper to remain when it shouldn't, so could be causing this effect.

Recently while emerging updated fftw-3.1.2 I also received the error: gcc-config error: g77 wrapper: Unable to determine executable. CTARGET=x86_64-pc-linux-gnu exec=g77 This happened on both ~x86 and ~amd64 testing systems with gcc-4.1.1. Yesterday I've found an easy, working solution, faster than switching compilers (which obviously takes a long time): # emerge -av =gcc-config-1* # emerge -av =gcc-config-2* The above solution worked great for fftw - it started to use gfortran instead of g77, so it compiled/installed fine without any other problems.

i'm using gcc 4.1.2 only here, on ~amd64. i removed /usr/bin/i686-pc-linux-gnu-g77 as suggested in previous comment. if i do : farfalla bin # /usr/bin/gfortran gcc-config error: /usr/bin/gfortran wrapper: Could not determine which compiler to use. Invalid CTARGET or CTARGET has no selected profile. and fftw will never compile. I dont know what to do.

I dont know what to do. > Same here and I noticed the message during the configure of other builds such as libXrandr (although it does seem to build okay). But shouldn't all this go in a bug about gcc-config, such as #157694 or rather one with a higher severity than "normal"? It's certainly not an eselect-compiler bug anyway.
