New Arch - PA-RISC

The following are notes for the build when comparing to CLFS 1.0 MIPS. These are edits I would do to the book at this point, as well as issues I am running into along the way.

In section 3.3 - Additional Packages for MIPS 64 Bit

Remove ArcLoad?-4.5

Not applicable to PA-RISC

Remove Colo-1.2.1

Not applicable to PA-RISC

Remove DVHtool-1.0.1

Not applicable to PA-RISC

Add PALO-1.14

Bootloader for PA-RISC systems. Latest version is 1.14-CVS20060409. Link: http://cvs.parisc-linux.org/download/palo-1.14-CVS20060409.tar.gz

In section 5.3 - Build Variables

Change line

export LFS_TARGET="mips64el-unknown-linux-gnu"

to

export LFS_TARGET="hppa-unknown-linux-gnu"

remove the line

export LFS_TARGET="mips64-unknown-linux-gnu" /* orig. for different sub-arch of MIPS /*

In section 5.5.1 - Installation of Linux-Headers

change: cp -Rv include/asm-mips /tools/include/asm to: cp -Rv include/asm-parisc /tools/include/asm

In section 5.7 - Cross GCC-4.1.1-Static

remove from configure: --with-abi=64 (abi is a MIPS-specific feature)

In section 5.7 - Cross GCC-4.1.1-Static:

The following error occurs when following the CLFS 1.0 MIPS-64 instructions:

I find this strange, as it only occurs when compiling source in the gcc/config/pa directory. I have tried passing CPPFLAGS=-I/usr/include and CFLAGS=-I/usr/include and it still does not find it. If I modify line 32 of gcc/config/pa/linux-unwind.h to include </usr/include/signal.h> then it finds that one file just fine. I am wondering why it is not finding this signal.h which does exist in /usr/include. I have also installed build-essentials on this debian-3.1r1 host system. I have installed linux-libc-headers-2.6.12.0 per a thread on google, and the issue reproduces.

Resolved above issue by adding CFLAGS and CPPFLAGS to the environment as opposed to the command line.

In section 5.4 - Build Flags

Remove the line: export BUILD64="-mabi=64" # not compatible with this arch

In section 5.7 - Cross GCC-4.1.1-Static

remove from configure: --disable-threads #required for glibc-2.4 to compile

Check for Gentoo Patches for toolchain. Any toolchain versions are ok for now.

SCRAP 1.x branch for HPPA (for now at least)

Begin basing build off of 2.0 ARM for now. New changelog notes to follow...

This patch is from http://sourceware.org/ml/binutils/2006-05/msg00245.html . It has been accepted and applied to the binutils cvs.

http://www.linuxfromscratch.org/~jciccone/binutils-2.17-hppa_tls-1.patch

32bit PC-RISC (hppa) was added a while ago and nothing has been reported broken.
