--- Comment #9 from angelo <angelo70 at gmail dot com> --- Hi Andreas, thanks. Not sure if i have to open another bug tracking. Now, with headers in sysroot, issue is solved so this bug can stay closed, but i get another error. /home/angelo/archivio/aziende/sysam/buildall/gcc-5.2.0/libgcc/config/m68k/linux-atomic.c:198:13: internal compiler error: in emit_library_call_value_1, at calls.c:4401 Very similar to this https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53833 Regards, angelo
