[Beignet] Compiling Beignet on Ubuntu 14.04

[Matthias Peter Walther]

Hello everyone,

I'm trying to compile Beignet on Ubuntu 14.04 here. When I run make, I
always get this error:

$ make
[  0%] Compiling
/home/mpw/gits/beignet/build/backend/src/libocl/src/ocl_workitem.cl
/bin/sh: 1: CLANG_EXECUTABLE-NOTFOUND: not found
make[2]: ***
[backend/src/libocl/usr/local/lib/x86_64-linux-gnu/beignet/ocl_workitem.bc]
Fehler 127
make[1]: *** [backend/src/libocl/CMakeFiles/beignet_bitcode.dir/all]
Fehler 2
make: *** [all] Fehler 2

I tried to google it, but no success. Any suggestions what is missing here?

Thanks for reading.
