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

[Eric P Caillibot]

Hello,

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
list) 

$ make

When prompted, I chose:

Target Processor Type
> 1. CLASSIC (CONFIG_CLASSIC) (NEW)

...

  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: ***

Error 2


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

$ make clean
$ make

...

Can anyone help me figure out what is going wrong?

Thank you very much!
