</span>What you are seeing looks absolutely normal. Buildroot creates its own<br>
sysroot, output/host/usr/powerpc-unknown-linux-gnu/sysroot, and copies<br>
the necessary stuff from the originally sysroot location to this<br>
Buildroot sysroot. This is done so that all other libraries built by<br>
Buildroot get installed into this Buildroot specific sysroot, instead<br>
of being copied back to the original sysroot, which would pollute your<br>
toolchain.<br>
<br>
So, if the build fails, please post:<br>
<br>
- Your complete .config file.<br>
- The last 100-200 lines of the build output.<br>
<br>
Also, please try to reproduce with Buildroot 2014.11. Buildroot 2011.02<br>
is very very old, and we've fixed/improved the external toolchain stuff<br>
significantly since 3 and half years.<br>
<br>
Thanks,<br>
<br>
Thomas<br>
