error log file

I am trying to build the most recent Beignet source (acquired here [https://01.org/beignet/downloads]) on my Ubuntu 14.04 system.

I thought I had all the dependencies but after I create the build directory and call cmake ../ if fails complaining about `drm_intel_get_pooled_eu' not being found.  I have libdrm-intel1 and libdrm-dev installed so I don't know what the problem is here.  I have attached the cmake error log file.

I have since learned that my versions of llvm and clang were not correct.  After updating those the cmake passes but now I am stuck with the make call where the output errors out like so:

Hi Charles,
Could you provide the LLVM and clang version you are using?
And could you try to rebuild the beignet with a git clone https://cgit.freedesktop.org/beignet/ , this may help you to find which files are generated and easy to reset to initial state.

Thanks
Xiuli

Xiuli,

As per your request I checked the LLVM and clang versions.  Somehow it was using the 3.4 clang version.  I swore I had set this correctly but I guess it didn't change.  After switching to 3.6 (LLVM = 3.6 as well), resetting the git repo and rebuilding it completed without a problem.

Thanks for your time,
Charles
