building clang for target off

Hello,
I am trying to build clang with GPU support, in particular with support for OpenMP target offload.
I want to build for a Xeon+Nvidia GPU.
I did this:
git clone https://github.com/clang-ykt/openmp.git
and built the OpenMP libomp.so
Then I try this:
git clone https://github.com/clang-ykt/libomptarget.git
but now I am ask for a user name, guest does not seem to work:

git clone https://github.com/clang-ykt/libomptarget.git
Cloning into ‘libomptarget’…
Username for ‘https://github.com’: guest
Password for ‘https://guest@github.com’:

Is this not a public branch of the repo?

I am interested to hear other peoples experience with this.
Thanks in advance,
Gabriele

Hi,

for the n-th time: This is not an officially supported Clang version. Trunk does not yet support offloading to Nvidia GPUs, see http://clang.llvm.org/docs/OpenMPSupport.html.

Regarding your problem: This repository does not exist or I'm also unable to find it. I think libomptarget is now integrated into the openmp repository, you might need to enable it with a CMake flag.

Jonas
