[parisc-linux] ELF tool chain builds hello world!!!

[Paul Bame]

To build the limping tool chain, grab the latest CVS bits for
binutils, gcc, and glibc, and follow a recipe somewhat like this
(it's not exact unfortunately, but should contain all the tricks):


PREFIX=$HOME/xc

cvs co binutils glibc gcc
cd gcc
ln -s ../binutils gcc/binutils

mkdir build-gcc
cd build-gcc
../gcc/configure \
	--disable-nls \
	--disable-shared \
	--target=hppa1.1-linux \
	--host=i586-pc-linux-gnu \
	--prefix=$PREFIX \
	--with-headers=/opt/puffin/include \
	--with-libs=$PREFIX/lib \
	--with-libc

make # need libiberty.a
# build until binutils is complete
cd binutils; make install

PATH=$PREFIX/bin:$PATH

cd ../..; mkdir build-glibc; cd build-glibc

../glibc/configure \
	--disable-nls \
	--without-nls \
	--disable-shared \
	--disable-profile \
	--enable-static-nss \
	--build=i586-linux \
	--host=hppa1.1-linux \
	--disable-sanity-checks \
	--with-headers=/opt/puffin/include \
	--prefix=$PREFIX

make # fails pretty soon

cp ../glibc/csu/crt?.S csu/
make # gets pretty far then fails looking for crtbegin.o

cd ../build-gcc
## Remove $PREFIX/bin from your $PATH!!!
## Repeat GCC configure from above then...
make install  # This installs the rest of gcc just in case...

cd ../build-glibc; make
make install MAKEINFO=

cd $(dirname $(find $PREFIX -name crtbegin.o))
ln -s $PREFIX/lib/* .

# Now you should be able to compile hello world

# The problem is that not all the headers seem to be available, in
# two categories: 1) some headers for example glibc/string/memory.h
# which ought to be installed as ...../include/string/memory.h, aren't
# and 2) things in <sys> like <sys/mount.h>
