glibc-2.1.2 cross-compile problem

I'm having a problem compiling glibc-2.1.2 using the xppc cross-compilation toolset. I (believe I) have followed the instructions for patching glibc
and all seemed fine, but I get the following, any help much appriciated!:

Are you running gcc-2.95.2?

I wasn't, but I grabbed it yesterday afternoon and been trying to compile it as per the instructions at
http://members.home.net/mmporter/linux/cross/ which I found in your FAQ. I grabbed and compiled the latest binutils okay. But.... can't get gcc to compile. It took a little pursuading before it would use the new binutils, and now complains about stdio.h being missing:

/usr/local/src/gcc-2.95.2/gcc/xgcc -B/usr/local/src/gcc-2.95.2/gcc/ -B/usr/local/powerpc-linux/bin/ -c -DHAVE_CONFIG_H -g -O2 -I. -I./../../include choose-temp.c

Aaaaaarrrrggggghhhhhhhhhhh!

The cross-tools want to have the target system header files
available in a directory called "sys-include" underneath the target triplet in the installation directory. The target triplet directory wants to look like /usr on the real system and the gcc-fixed header files will go into the regular "include" directory.

Are you sure you followed the directions on my site? You need to configure your build of gcc with "--with-newlib" then link to your kernel headers, then build glibc.

Yes... after all they are not complex instructions.

I sorted that problem (stdio.h missing) by copying the newlib headers into /usr/local/powerpc-linux/include. So it gets past that now. But....

/usr/local/src/gcc-2.95.2/gcc/xgcc -B/usr/local/src/gcc-2.95.2/gcc/ -B/usr/local/powerpc-linux/bin/ -c -g -O2 -I. -I. -D_IO_MTSAFE_IO iogetline.c -o pic/iogetline.o /usr/local/src/gcc-2.95.2/gcc/xgcc -B/usr/local/src/gcc-2.95.2/gcc/ -B/usr/local/powerpc-linux/bin/ -c -g -O2 -I. -I. -D_IO_MTSAFE_IO iogetline.c

                 from libioP.h:47,
                 from iogetline.c:26:

libio.h:30: _G_config.h: No such file or directory make[1]: *** [iogetline.o] Error 1 make[1]: Leaving directory `/usr/local/src/gcc-2.95.2/powerpc-linux/libio'

So now I'm where Graham Stoney was at Date: Thu, 12 Aug 1999 14:34:44 -0400.
I *think* it is looking for _G_config.h from my host includes, but it simply isn't putting the path on the command line. Which I think it did at one point, or at least on of those -I. was -I./../../include. Arghh I'm must be going mad, or stupid. Surely its should not be as bad as this?

Any help very much appreciated!

Hi Elizabeth,

Can't remember what I did to solve this, but I got past it somehow. Try doing a "make install", and see if it installs enough of the compiler to go ahead with the glibc build. I found I had to build gcc in two passes, firstly with --with-newlib, and then without once glibc was installed.

Agreed. Funnily enough though, it's better than it used to be. I remember when I was a lad, before "configure" was around...

Good luck,
Graham
