i've used sys-devel/crossdev-20150716 by typing "crossdev avr" cross-avr/binutils-2.25.1-r1 emerged fine, but gcc failed in stage1 with : checking for avr-gcc... /home/notmpfs/portage/cross-avr/gcc-4.9.3/work/build/./gcc/xgcc -B/home/notmpfs/portage/cross-avr/gcc-4.9.3/work/build/./gcc/ -B/usr/avr/bin/ -B/usr/avr/lib/ -isystem /usr/avr/include -isystem /usr/avr/sys-include checking for suffix of object files... configure: error: in `/home/notmpfs/portage/cross-avr/gcc-4.9.3/work/build/avr/libgcc': configure: error: cannot compute suffix of object files: cannot compile Reproducible: Always

I tried another gcc version, using --g 4.8.5, but the result is the same
If you have binutils-config-5, then try downgrading to binutils-config-4, or try my patch from bug #562460
I indeed do have binutils-config-5 installed. I tried masking it, but i have other packages requiring it: >=sys-devel/binutils-config-5 required by (sys-libs/binutils-libs-2.25.1-r1:0/2.25.1::gentoo, installed) So I tried patching my /usr/bin/binutils-config with + if [[ ${TARGET} != ${HOST} ]] ; then + for x in lib* ; do + atomic_ln "${LIBPATH}/${x}" "${dstlib}" "${x}" + done + fi then uninstalled cross-avr/binutils and restarted 'crossdev avr'. I'm not sure about the result. I think it worked slightly more than previously, but it still fails in some configure, though differently.

(seems like i have the same error as Alexander Tsoy)
Alexander : but #147155 doesn't prevent emerging, it's "only" that the emerged stuff doesn't work. And even if this bug has been there for years, there are workarounds.
(In reply to Thomas Capricelli from comment #13) Yes. Although ldscripts symlink fixed this error, I got another linker error later at configure phase. Here is the workaround that works for me: # echo 'cross-avr/gcc sanitize' > /etc/portage/profile/package.use.mask/cross-avr-nosanitize IIUC address sanitizer is not supported on avr. So this issue should be fixed either in crossdev (GUSE="-sanitize") or even in toolchain.eclass (do not add "sanitize" to IUSE for unsupported CTARGETs).
So this is a dupe of bug #525910 (just found it :/ )
(In reply to Alexander Tsoy from comment #14) That did it! Thanks for the hint. I know have an avr-4.9.3 (again, i had an old old that i removed because i thought it would be easy for crossdev to build a more recent one ..)
