Glibc compilation errors

So here are the errors. I get these when i'm trying to compile glibc for the toolchain.

Code:

I should note that i'm using Ubuntu 9.04 and instead of version 2.6.27.4 of the kernel i decided to use a newer release that supports ext4(2.6.29.2).

I read in another post that a solution could be recompiling GCC but i haven't tried it since it takes a lot of time.

Testing if the new gcc is as good as the system one :
That is very easy to find out :
Just make a test compile of glibc, using your system gcc,
/usr/bin/gcc ( 4.3 ), and a different 'configure'.
( From scratch, in a new unique directory in /home/"user"/ ).

Well i did what you suggested and gcc(from the host system) doesn't seem to be able to compile glibc.

The question is what should i do? Should i try to install another version of gcc on the host system(maybe 4.4) and then recompile gcc from the toolchain ?

I guess, you will have to repeat all steps connected
to glibc. ( Don't try gcc-4.4, (my opinion), gcc-4.3 is OK.)

Else ask in the LFS forum, remember all information :
Host, LFS version, chapter. ( See 1.5.1 ).

Well either Ubuntu is cursed or gcc 4.3 isn't capable of compiling Glibc. But gcc 4.4 compiles glibc fine, so i think i'm gonna switch to it.
