Hey all, I've been trying to get safecode up and running for a while
now and am simply not having much luck. As far as I can tell I'm
following the instructions on the site correctly, but I'd really
appreciate it if you'd take a look and see if there was anything
obvious that I'm doing wrong.

For background, I'm running Ubuntu 10.04 on a fairly beefy x86_64 machine.

The issue occurs after I go through what appears to be a modestly
successful build routine. The script I'm using to build is:

#! /bin/sh

set -e

# We do all of this in /tmp to make sure we're building locally
cd /tmp

# Get mainline llvm
echo "Getting llvm..."
svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm

# Get all the projects we need
echo "Getting safecode projects..."
cd llvm/projects
svn co http://llvm.org/svn/llvm-project/poolalloc/trunk poolalloc
svn co http://llvm.org/svn/llvm-project/safecode/trunk safecode
svn co http://llvm.org/svn/llvm-project/cfe/trunk clang

# Configure everything
echo "Configuring..."
cd ..
./configure

# Make everything
echo "Making..."
make -j16 tools-only > /tmp/make_tools.out
cd projects/poolalloc
make -j16 > /tmp/make_poolalloc.out
cd ../safecode
make -j16 > /tmp/make_safecode.out
cd ..

# Install
echo "Installing..."
cd ..
sudo make install > /tmp/install_all.out
cd projects/poolalloc
sudo make install > /tmp/install_poolalloc.out
cd ../safecode
sudo make install > /tmp/install_safecode.out

# Go home
echo "Done."


I can provide the various output files if you want, but there's
nothing in them that immediately appears to be an error. It does emit
a pair of these warnings:

/tmp/llvm/Makefile.rules:1192: Bytecode libraries require LLVM capable
compiler but none is available ****

I'm not clear on why this is; I have both llvm-gcc and clang installed:

user@machine:/tmp$
 which llvm-gcc
/usr/bin/llvm-gcc
user@machine:/tmp$
 which clang
/usr/local/bin/clang

Regardless, when I attempt to compile the test program given at
http://safecode.cs.illinois.edu/docs/UsersGuide.html I get the
following linker errors:

clang: error: linker command failed with exit code 1 (use -v to see 
invocation)

I can provide the output of the -v option if it helps, and apologies
if this is something really obvious- I'm new to LLVM as well as
safecode. Thanks for your time and assistance in any event,
