Hi, All,

I am a newby for ppc embedded linux. When trying to build the cross compi=

chain, I got some error message in making glibc (binutils and gcc are suc=

built).

Error message is:

My environments are:
=20
kernel: 2.26.     25
gcc & powerpc-linux-gcc: 4.3.2
binutils:2.18
glibc:2.7, configured with  linuxthreads enabled and nptl disabled.

glibc 2.7 does not support linuxthreads.  It is nptl only.  And you
should really be using nptl anyway.
