LibBSD PowerPC motorola_shared BSP PCI Support

[Heinz Junkes]

I am currently trying git rtems6.

../source-builder/sb-set-builder --prefix=$HOME/.rtems --log powerpc_beatnik.log --no-clean --target=powerpc-rtems6  --with-rtems-bsp=beatnik 6/rtems-powerpc 6/rtems-kernel

works …

Unfortunately It fails here:

../source-builder/sb-set-builder --prefix=$HOME/.rtems --log libbsd.log --no-clean --target=powerpc-rtems6 --with-rtems-bsp=beatnik --host=powerpc-rtems6 6/rtems-libbsd
