I am using Ubuntu Linux 10.10, with which, comes Clang based on LLVM 2.8. When I use Clang to build google-test, it complains that “variadic template” is a C++0x feature and is not yet supported.
However, the Clang installed by Homebrew on my Mac OS X 10.7 (Lion) is based on LLVM 3.0 and works well with google-test.
The homepage of LLVM listed pre-built Clang and LLVM 3.0 for Ubuntu 11.04 and 11.10. So I guess I would have to upgrade to at least Ubuntu 11.04.
FreeBSD 9.0 comes with Clang based on LLVM 3.0.
