When installing GCC 4.3.4 on Ubuntu 11.10, following these instructions, I am encountering many errors at the make stage. The full dump is here, but the important parts seem to be some missing files, starting with:
/usr/include/features.h:323:26: error: bits/predefs.h: No such file or directory
/usr/include/features.h:356:25: error: sys/cdefs.h: No such file or directory
/usr/include/features.h:388:23: error: gnu/stubs.h: No such file or directory
In file included from ../../.././libgcc/../gcc/tsystem.h:90,
from ../../.././libgcc/../gcc/libgcc2.c:33:
/usr/include/stdio.h:36:25: error: bits/types.h: No such file or directory
In file included from ../../.././libgcc/../gcc/tsystem.h:90,
from ../../.././libgcc/../gcc/libgcc2.c:33:
Does anyone have any ideas why these can’t be found? A google search indicates they are standard C headers.
(N.b. at the configure stage I had to install dependencies GNU MPFR and GMP).
You have to install the libc-dev package.
