(please see the attach pic) 2. i saw there are some test sample files in uclibc/test, and it seem crossng will not compile it and we have to compile them by ourself. 3. I can get x86 with uclibc which crossng made for me, and I use it to compile some simple program. But how can I activate the new dynamic loader instead of the default one for testing the toolchain? appreciate your help :) miloody
