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

4. make

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

# Error file shows the following:

try changing the source path to /usr/include or wherver the glibc
headers are included think tht path you have given is the linux kenel
include files u dont expect to find stdlib.h

It could be that the configure portion of the build failed.

"--targrt" must be spelled "--target"

You could also try looking at Karim's Yaghmour's site:
http://www.embeddedtux.org & buy the book Building Embedded Linux Systems by
the same author.
