Re: help, build Cross GCC

[Wang Yong <wung_y@263.net>]

hi, Dan:
i am now building a gcc for powerpc on i686. i have downloaded 
binutils-2.9.5.0.16 and gcc-2.95.2. i need the latest version of gcc
for i want to build program for powerpc403 and powerpc401.
and then, i first built binutils by these step:
1. decompress the binutils-2.9.5.0.16.tar to a temp directory.
2. chdir to that directory and run "./configure
--target=powerpc-linux-gnu"
3. run "make" and "make install"

after all these done, i build binutils to /usr/local/bin. 
next i begin to build gcc:
1. decompress the gcc-2.95.2 to another temp directory.
2. chdir to that directory and run "./configure
--target=powerpc-linux-gnu"
3. run "make" and "make install"

but this time, i failed. make told me it failed to find stdlib.h and
uinstd.h
when build libgcc2.a. then i tried to modify the Makefile and this line:
CFLAGS = -g -O2 -Dinhibit_libc

after run make, another error came out :-(

--------------------
somebody told me i must install lib and include file for the ppc first. 
but where to download them. 
do you think i still miss something.  would you please show me the right
step to build?

regards,
Wang
