[Buildroot] Problem involving libc/libc_so.a(pread_write.os)

I am trying to set up Buildroot on a host running ubuntu, my target
being a powerpc 405, running version 2.4.26 of the Linux kernel.

This is what I did, after checking Buildroot out of SVN:

$ make menuconfig

-> In the menu, I changed GCC compiler version to 4.1.2 (although in a
previous attempt I left the default choice in place and ended up with
the same result)
-> Changed Target Architecture to powerpc
-> Kernel Headers left at Linux 2.4.31 (since 2.4.26 is not in the

$ make

When prompted, I chose:

Target Processor Type


  STRIP -x -R .note -R .comment lib/libc.a
  AR cr lib/libc.a
  STRIP -x -R .note -R .comment lib/uclibc_nonshared.a
  AR cr lib/uclibc_nonshared.a
  AR cr libc/libc_so.a
  LD libuClibc-0.9.29.so
libc/libc_so.a(pread_write.os):(.text+0x14): undefined reference to
make[2]: *** [lib/libc.so] Error 1
make[1]: *** [lib/libc.so.0] Error 2
make[1]: Leaving directory
make: ***
Error 2

After this point, I tried changing different settings, but ultimately,
subsequent attempts always got me the same error.

$ make clean
$ make


make MAKE="make -j1"

                PREFIX= \

make[1]: *** [install_runtime] Error 1
make[1]: Leaving directory
make: *** [/home/epc/dev/buildroot/build_powerpc/staging_dir/lib/libc.a]

Can anyone help me figure out what is going wrong?

Thank you very much!
