[Buildroot] gcc 4.2.4 toolchain

[Buildroot] gcc 4.2.4 toolchain

[Andrew Chambers]

Hello,

Recently ive tried to build a custom mips linux kernel version 2.6.28 under
the buildroot-2012.02. However all gcc versions listed do not support
some deprecated gcc inline assembly syntax being used extensively.

Is it possible to use gcc 4.2.4 with buildroot-2012.02 . I manually added
it to the buildroot menu but when attempting a mips build the toolchain i
recieve the following errors while building the cross compiler ...

                 from
/Users/andrewc/Desktop/buildroot-2012.02/output/toolchain/gcc-4.2.4/gcc/unwind-sjlj.c:36:
/Users/andrewc/Desktop/buildroot-2012.02/output/toolchain/gcc-4.2.4/gcc/gthr-posix.h:43:21:
error: pthread.h: No such file or directory

i have tried using linux threads and native posix options , but both
require pthread which cant be found.

4.2 support got removed back in Dec 2011, so perhaps give
buildroot-2011.11 a try?

Hi Andrew,

It is pretty simple to add back gcc 4.2.4 support to buildroot. The
issue you see here is due
to a missing patch, which should be available in the older releases as
Peter suggested. The
patch in question is called 1001-gcc-4.2.x-inhibit-libc.patch but it
is probably safest just to
add back all the 4.2.4 patches.
