Sergey Tachenov <stachenov at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |stachenov at gmail dot com --- Comment #2 from Sergey Tachenov <stachenov at gmail dot com> 2013-04-03 16:50:11 UTC --- I have just encountered it with 4.8.0. Instead of adding /dev/null, I have changed ifneq ($(SHLIB_MKMAP),) to ifneq ($(SHLIB_MAPFILES),) I'm not sure if it doesn't break anything, though, as in my case the resulting libgcc.map isn't created at all. The build completed anyway, and the resulting GCC seems to be working fine, though.
