I have to cross compile toolchain for arm processor (armv5TE). I took latest binutils version 2.15 and compiled for the architecture arm-linux. It compiled fine. We took latest source code for gcc version 3.4.2 and started to build gcc for c language. But we end up in the compilation error "unistd.h and stdio.h : No such file or directory". Now how can we resolve this issue. Any procdeure to compile latest gcc with latest kernel 2.6.8.1 is available or not. Could anybody give me the suggestion regarding this....
