That would be great! I'll add your notes to the README and will also
make them available on The Pure website.

In fact, I now seem to recall that the install wasn't all that
difficult, it's just the documentation on the LLVM website which is
confusing. I actually followed the "Building the LLVM GCC Front-End"
page (http://llvm.org/docs/GCCFEBuildInstrs.html) rather than the
"Getting Started" guide, which is much shorter (you'll have to fiddle
with some of the options, though, because that page actually talks about
building the Ada frontend).

So IIRC this is the procedure I followed (please, someone should verify
these steps, as it's been a while since I've done this):

*Step#1:* Unpack the sources from both llvm-2.2.tar.gz and
llvm-gcc4.2-2.2.source.tar.gz to some directory SRCDIR and go there (cd
SRCDIR). You can find the downloads here:
http://llvm.org/releases/download.html#2.2
(Just ignore all the binary packages and get only those two source
tarballs.)

*Step#2:* Rename the source directories:

mv llvm-2.2 llvm
mv llvm-gcc4.2-2.2.source llvm-gcc-4.2

*Step#3:* Make a build directory llvm-objects for llvm and go there:

mkdir llvm-objects
cd llvm-objects

*Step#4:* Configure, build and install LLVM (set prefix to wherever you
want it to, and use ENABLE_OPTIMIZED=0 instead of ENABLE_OPTIMIZED=1 to
build LLVM with checking enabled):

../llvm/configure --prefix=/usr/local
make ENABLE_OPTIMIZED=1
sudo make install

*Step#5:* Make a build directory llvm-gcc-4.2-objects for llvm-gcc and
go there:

cd ..
mkdir llvm-gcc-4.2-objects
cd llvm-gcc-4.2-objects

*Step#6:* Configure, build and install llvm-gcc (you might wish to add
other languages like ada and fortran to the --enable-languages option):

../llvm-gcc-4.2/configure --prefix=/usr/local --enable-languages=c,c++ \
--enable-checking --enable-llvm=$PWD/../llvm-objects --disable-shared \
--disable-bootstrap --disable-multilib
make
sudo make install


That should be all, IIRC. I'm not sure whether you actually have to
install llvm-gcc (steps 5 and 6) if you only want to compile another
LLVM application, but those are the steps I followed on both my
development box (SUSE 10.1) and my laptop (SUSE 10.3), and it allows me
to build Pure just fine.

HTH,
Albert
