Problem in compiling glibc headers for ppc

["mojtaba" <kernelppc at gmail dot com>]

Dear all,
I am trying to create a cross compiler for ppc using crosstools. My target
is: powerpc-405-linux-gnu.

When it goes to the " install glibc headers needed to build bootstrap
compiler .." part, I get this error during configuration:
" configure: error: this configuration requires -mlong-double-128 IBM
extended format support".

As I thought this phase may not be necessary for gcc 4.2.2 I just tried to
omit it. But in further phases I got some stupid errors regarding some
header files like unistd.h or hthread.h. Anyway, It would be grateful if you
can help me on this.

Regards,
Mojtaba

My build system is ubuntu 2 2.6.22 i686 GNU/Linux The glibc version is 2.7


This is the complete log:


crosstool: binutils built ok
+ echo Install glibc headers needed to build bootstrap compiler -- but
only if gcc-3.x
Install glibc headers needed to build bootstrap compiler -- but only if
gcc-3.x
