About the source codes of the toolchain: 1. I am sorry, for the previous version that we did not include the source codes of the uclibc. 2. We made our toolchain from "buildroot", it comes from http://buildroot.uclibc.org. 3. And, to get the toolchain source codes that we used, you could untar the tgz file that named "cross-i386-linux-gcc.tgz" or "cross-i386-linux-gcc.tar.bz2", and it will be stored to /opt.It is big, because we left all the source codes inside it for GPL checking. command: cd / tar xzvf cross-i386-linux-gcc.tgz or tar xvfj cross-i386-linux-gcc.tar.bz2 of course, you have to become root first. 4.You may read the file "README" in /opt/buildroot, and it will help you to rebuild the cross complier if necessary. Unless you know what you are doing, please, use the binary codes that we gave you in "cross-i386-linux-gcc.tgz" or "cross-i386-linux-gcc.tar.bz2". It is enough for most people. --That's all--
