Issue trying to build LLVM and clang

I'm trying to build LLVM and clang on my machine (Ubuntu 12.04). I followed the instructions on http://clang.llvm.org/get_started.html up to step 6 (build LLVM and clang). When I make, I get a whole load of warnings about potentially incompatibly plugin versions (to do with dragonegg?). But the whole thing fails with these messages:

llvm[2]: Linking Debug+Asserts executable llvm-tblgen
/usr/bin/ld: /home/peter/llvm/build/Debug+Asserts/bin/llvm-tblgen: hidden symbol `llvm::Type::~Type()' isn't defined
/usr/bin/ld: final link failed: Bad value
collect2: ld returned 1 exit status
make[2]: *** [/home/peter/llvm/build/Debug+Asserts/bin/llvm-tblgen] Error 1
make[2]: Leaving directory `/home/peter/llvm/build/utils/TableGen'
make[1]: *** [TableGen/.makeall] Error 2
make[1]: Leaving directory `/home/peter/llvm/build/utils'
make: *** [all] Error 1

So any help you could give me would be really helpful.

Thanks

I ended up deleting the llvm folder and checking everything out again, and it worked, so I'm just putting it down to bad timing.

You may want to use the existing LLVM packages, as provided by your distributions.

This askubuntu question about LLVM 3.1 could be relevant.

And you should at least do apt-get build-dep llvm-3.1-dev to ensure all dependencies are available.

You could also ask help on some LLVM related mailing list.
