Hello once again, In all the documentation found on the web it says that after building binutils and gcc I should be able to compile the MIPS Kernel sources. Or my problem is that I can not compile the sources. Any ideas why ? The compilation gives me the following error: cc1: warnings being treated as errors. I used binutils 2.8.1 with the patch and egcs 1.0.3a along with add-ons ( crypt and linuxthreads ). Another question : in all the docs that I found says apply patch binutils--mips.patch, gcc--mips.patch and the same for glibc. I did a search for binutils-2.8.1-mips.patch and I did not find anything. Can anyone tell me where to find those patches ? Regards, Nicu
