--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-05-05 09:11:44 UTC --- Shouldn't this be Component=bootstrap not c++ ? I assume the linux-libc-dev package is installed? That provides asm/errno.h What compiler are you using to bootstrap? If it's the standard system compiler it should know to look in /usr/include/x86_64-linux-gnu, if not then it's a bug in the Ubuntu gcc package What is the output of "gcc -v -x c /dev/null -c" ?
