[Clfs-support] CLFS for ppc on LFS 6.3 host

Tue Jul 8 13:26:33 PDT 2008

Ken,
First, thank you for going to the trouble of helping me.
In answer to your question 1 below, I did apply all patches stated in chapter 5 of the book, and I did set STARTFILE_PREFIX_SPEC to "/tools/lib/" in gcc/config/rs6000/linux.h.  As I follow the steps I double check that sed operations and the like actually provide expected results, using diff or otherwise.
As regards question 2: CLFS_HOST="i686-cross-linux-gnu"; CLFS_TARGET="powerpc-unknown-linux-gnu".
For question 3, my command history is gone for all but the last attempt which does indeed compare correctly with the book, which incidentally built to completion with success.   Unfortunately the target for which I need to build ppc binaries is running a kernel version 2.4.21, which will not load and run a binary (hello world) built using my clfs cross compiler.
When I compiled and linked a hello world program with my clfs cross compiler without -static switch, the binary would report "file not found" when it was run on the target.  It was necessary to compile and link with -static switch to get the binary to run and report: FATAL: kernel too old, followed by Segmentation fault.  I suppose that the file not found indication was that the binary could not load a necessary library module.
The system integrator that supplied the target systems also has provided rpms for gcc, binutils, glib of the same vintage as their kernel, so I am now going to attempt to build the cross compiler using the package versions supplied by the integrator, although no patches are provided.

My goal is to be able to build a PAM aware passwd package, to be able to strengthen up the passwords on the target systems. 
Again, thank you sincerely for helping.  Please let me know if you have any other suggestions.  Regards,  Anthony Drake.

I'm baffled.  I've just completed this from one of my x86 LFS-6.3
systems.  Mine was fine, as I expected.  What baffles me is that
I've got a lot more going on.

Mine has a _lot_ more after it leaves libdecnumber, and among other
things that includes creating crtbegin.o and such like.

At this point mine has
[...]MULTILIB_CFLAGS="" T= crtbegin.o crtend.o crtbeginS.o
crtendS.o crtbeginT.o ecrti.o ecrtn.o ncrti.o ncrtn.o crtsavres.o

make[4]: `crtbeginT.o' is up to date.
cat ../../gcc-4.2.4/gcc/config/rs6000/eabi-ci.asm >ecrti.S

it then runs through ecrtn.S ncrti.S ncrtn.S crtsaveres.S and then
creates mcrtn.o and crtsaveres.o.

Like I say, I've really no idea why yours is so different.  But
then, I try not to get too involved in the mechanics of the
toolchain.  It seems to think that a lot of the basic object files
(those which get linked into the executables gcc builds) don't need
to be made or re-made, which implies it might be confused about what
architecture it is building for, or where it should be building.

First question: for each of the two gcc builds, did you apply all of
the patches listed for that build, and only those patches, and did
you successfully add the STARTFILE_PREFIX_SPEC to the end of what
was in gcc/config/rs6000/linux.h ?

Second question: what do you have for CLFS_HOST and CLFS_TARGET ?  I
hope you're going to tell me i686-pc-linux-gnu and
powerpc-unknown-linux-gnu.

Third question: did you pass all the correct options to the binutils
configure ?
