Not building on Ubuntu 13.10 64

[VincentSC]

Trying to build it a fresh checkout, but when at 95% an error is hit. llvm (3.2), webcl-clang-dev and webcl-validator are up-to-date. What I did different was creating symbolic links to clang and webcl. What is going wrong?

We recently updated validator to work with unmodified llvm/clang 3.4 unfortunately readme.md was not updated in change. I'll update build instructions tomorrow. Issue #71 is about readme update.

Thank you for the quick answer. I think I saw it in the mailinglist, now you say so. I now did:

git clone http://llvm.org/git/llvm.git
git clone http://llvm.org/git/clang.git
ln -s ../../webcl-validator/ clang/tools/webcl-validator
ln -s ../../webcl-validator/ clang/
cd build
make -j4

That seems to be working. Great!
