Georg-Johann Lay <gjl at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID --- Comment #4 from Georg-Johann Lay <gjl at gcc dot gnu.org> 2012-11-01 08:26:21 UTC --- Don't configure GCC in the source tree. Read the online documentation on configuring GCC again. If you configured in the GCC sources, remove the sources and retrieve them again to be sure they are not messed up by the configure in the source tree. You must have a working avr-binutils in the path. Alternatively, you can build and install avr binutils with the same --prefix before configuring avr-gcc. You don't need to add it to the path in the latter case. You need binutils 2.23 or higher for avr-gcc 4.7, see the GCC 4.7 release notes.
