pb compiling cross gcc, binutils, glibc and so on ...

[BREUVART Jean-Charles]

Hello world !

I'm trying to create a cdk, the host is a PIII runnning RedHat 8.0 (kernel
2.4.18), and the target is GNU kernel 2.4.20 running on a PPC755B
proprietary board. I've read lots of HOWTOs but I haven't succeeded yet !!!

RedHat 8.0 comes with gcc 3.2, binutils 2.13.90.0.2, make 3.79.1, I don't
know how to get the libc version ...

One told me that gcc 3.2 wasn't a nice version to create a cross-compiler
(actually, I've tried and this seems to be true), so I've downloaded from
www.gnu.org the following :

 - gcc-2.95.3.tar.gz and gcc-core-2.95.3.tar.gz
 - binutils-2.13.90.0.4.tar.gz and binutils-2.12.90.0.7.tar.gz
 - glibc-2.3.tar.gz and glibc-linuxthreads-2.3.tar.gz
 - make-3.80.tar.gz
 - linux-src-2.4.20.tar.gz

I' succeeded in building a native gcc 2.95.3 and make 3.8, and used them to
create the famous Hello world C program, actually all that stuff works. But
I still remain to encounter pb while creating the cdk !!!

here is what I did :

 1. restrict $PATH to /sbin:/bin:/usr/sbin:/usr/bin
 2. build a native gcc core 2.95.3 from scratch in /usr/src/gcc-2.95.3/ dir,
and install it in /usr/local/ (the default) :
      - cd /usr/src/gcc-2.95.3/
      - make clean
      - make distclean
      - ./configure --enable-languages=c,c++ ; this uses my RedHat
distribution's cc, which link to gcc
      - make bootstrap
      - make install
 3 build make 3.80 in /usr/src/make-3.80/ dir, and install it in /usr/local/
(the default) :
      - cd /usr/src/make-3.80/
      - make clean
      - make distclean
      - CC=/usr/local/bin/gcc ./configure (I don't know if it's better to
use gcc 2.95.3 or gcc 3.2, however, this uses RedHat distribution's binutils
!)
      - make
      - make install
 4. build binutils 2.12.90.0.7 for powerpc cross compile, and install it in
/opt/powerpc-linux/ :
      - cd /usr/src/binutils
      - make clean
      - make distclean
      - CC=/usr/local/bin/gcc ./configure --target=powerpc-linux
--enable-shared --with-newlib --prefix=/opt/powerpc-linux (I still don't
know if it's better to use gcc 2.95.3 or gcc 3.2)
      - make
      - make install
5. build gcc core 2.95.3 for powerpc cross compile, and install it in
/opt/powerpc-linux/ :
      - cd /usr/src/gcc-2.95.3/
      - make clean
      - make distclean
      - CC=/usr/local/bin/gcc ./configure --target=powerpc-linux
--enable-shared --enable-languages=c --with-newlib
--prefix=/opt/powerpc-linux
      - add /opt/powerpc-linux at the end of $PATH, otherwise make doesn't
find powerpc-linux-as, powerpc-linux-ld and so on
      - make

Here is the trouble :

choose-temp.c:29: stdio.h: Aucun fichier ou r?pertoire de ce type
choose-temp.c:30: sys/types.h: Aucun fichier ou r?pertoire de ce type
choose-temp.c:32: unistd.h: Aucun fichier ou r?pertoire de ce type
choose-temp.c:35: stdlib.h: Aucun fichier ou r?pertoire de ce type
choose-temp.c:38: sys/file.h: Aucun fichier ou r?pertoire de ce type

there aren't any of those in /opt/powerpc-linux/ or its subdirs

this the same trouble I had when I tried to build directly a cross gcc
2.95.2 for powerpc-linux with my RedHat distribution's gcc and binutils ...

So here are my questions :

 - did anyone do that before ?
 - does a pre-compiled version of such a cross dev toolsets already exists
for x86-pc-linux or sparc-sun ? I heard about "ELDK"
by Wolfgang Denk
 - is what I did wrong ?
 - where should the cross gcc build process search for those headers ? How
to indicate it ?
 - must I use native binutils or cross binutils to build a cross gcc ?
 - to build the bin utilities, including binutils, for the embedded linux
kernel's filesystem that will run on the PPC755B, I think I'll use the cross
gcc to build them from their source code ? I think that the one build in 4.
won't run, they only run on my host ?

if needed, I can change my host and use a Sun Workstation runnning SunOS
5.5.1 ...

So thanks in advance.

Jean-Charles Breuvart

[Claus Gindhart]

A good and stable binary package of a complete gcc cross toolchain
is supplied with SuSE Linux 8.0.

This is the version:
----
claugi@claugi-wnt:~> /opt/cross/bin/powerpc-linux-gcc --version
2.95.3
---
I used with cross-toolchain succesfully on various PowerPC platforms.
It is no problem to install a SuSE RPM on a redhat system, if you
have no fear to do a "rpm -i --nodeps".

Unfortunatley these funny guys decided to remove this package in
their new 8.1 package; but maybe they have it still available for
download, or You can purchase a 8.0 version.

Hello,

You can get the libc version by directly executing /lib/libc.so.6

These errors tell you it can't find the header files for your specific target
platform.
You can either copy these from an existing PPC system, or build glibc from
scratch for your system.
A good guide for creating glibc from scratch is to be found at:

http://penguinppc.org/embedded/cross-compiling/

I hope this helps.

It's true that there are no any of those files. They are in glibc which you have not compiled yet.

I was given this script ... it works ;-)

Just match the directory structures ;-)

Maybe it will help ... make sure you have bison,flex,tetex installed ...

Good luck,
