Building gcc for powerpc

Hi All,

# As I am building cross toolchain for ppc 8xx CPU. # The following steps were performed

1. Built binutils
2. Configured the linux kernel (menuconfig)(ofcourse with make clean etc.)
3. Building gcc (pass 1)

• Step 3 expanded: i. extracted the code from gcc-2.95.3.tar.gz ii. Applied libchack solution iii. ran configure as: ../gcc-2.95.3/configure --targrt=powerpc --prefix=/usr

--with-headers=/usr/src/linux/include --enable-languages=c

--disable-threads

1. make

• Here I get errors that says: stdlib.h not found and unistd.h not found.

# Error file shows the following:
