[Beignet] beignet 0.9.2-2 looking for MesaOpenCL on Intel laptop, fedora 21

[David Liebman]

Hello.

I have compiled PyOpenCL for my fc21 computer. My computer has an Ivy 
Bridge chipset and fc21 sports Beignet version 0.9.2-2.fc21. I am having 
trouble with a simple program that computes sums. This is the program 
listing:

import pyopencl as cl
import numpy
import sys
import time

class CL(object):
     def __init__(self, size=10):
         self.size = size
         self.ctx = cl.create_some_context()
         self.queue = cl.CommandQueue(self.ctx)

     def load_program(self):
         fstr="""
         __kernel void part1(__global float* a, __global float* b, 
__global float* c)
         {
             unsigned int i = get_global_id(0);

            c[i] = a[i] + b[i];
         }
          """
         self.program = cl.Program(self.ctx, fstr).build()

     def popCorn(self):
         mf = cl.mem_flags

         self.a = numpy.array(range(self.size), dtype=numpy.float32)
         self.b = numpy.array(range(self.size), dtype=numpy.float32)

         self.a_buf = cl.Buffer(self.ctx, mf.READ_ONLY | mf.COPY_HOST_PTR,
                                hostbuf=self.a)
         self.b_buf = cl.Buffer(self.ctx, mf.READ_ONLY | mf.COPY_HOST_PTR,
                                hostbuf=self.b)
         self.dest_buf = cl.Buffer(self.ctx, mf.WRITE_ONLY, self.b.nbytes)

     def execute(self):
         self.program.part1(self.queue, self.a.shape, None, self.a_buf, 
self.b_buf, self.dest_buf)
         c = numpy.empty_like(self.a)
         cl.enqueue_read_buffer(self.queue, self.dest_buf, c).wait()
         print ( "a", self.a)
         print ( "b", self.b)
         print ( "c", c )

def add(s=10) :
     starttime = time.clock()
     matrixmul = CL(s)
     matrixmul.load_program()
     matrixmul.popCorn()
     matrixmul.execute()
     endtime = time.clock()
     print s, endtime - starttime

if __name__ == '__main__':
     add(1)
     add(2)
     add(3)


This is the error I get when I run the program:

[dave at localhost awesome-test]$ ./arrays_opencl.py
Traceback (most recent call last):
   File "./arrays_opencl.py", line 3, in <module>
     import pyopencl as cl
   File 
"/usr/lib64/python2.7/site-packages/pyopencl-2014.1-py2.7-linux-x86_64.egg/pyopencl/__init__.py", 
line 28, in <module>
     import pyopencl._cl as _cl
ImportError: libMesaOpenCL.so.1: cannot open shared object file: No such 
file or directory

NOTE: I do not have libMesaOpenCL on this computer. I uninstalled it and 
then re-installed pyopencl when I fedup'd to fc21. In fc20 Beignet 
worked correctly.

also for the record, this is the configuration line that I used when 
installing pyopencl:

[dave at localhost awesome-test]$ ./configure.py 
--cl-lib-dir=/usr/lib64/beignet --cl-libname=cl
