"error: unknown argument: '-g'" with Beignet

[Ralf Stubner]

When working with ArrayFire on a Debian system with Beignet installed, I encountered a bug that I reported there: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=881054

I have the impression that it is similar to #20, but now for an Intel GPU. I was able to circumvent this issue by rebuilding the Debian package for clBLAS with the relevant parts commented out:

clBLAS/src/library/blas/generic/common.c

Lines 541 to 543 in cf91139

 // Nvidia runtime does not appear to support the -g flag, at least in their OpenCL v1.1 runtime 
 if( target.ident.vendor != VENDOR_NVIDIA ) 
     addBuildOpt( opts, BUILD_OPTS_MAXLEN, "-g" ); 

However, I am wondering if a proper solution within clBLAS would be possible. Could the vendor check be extended to also include Intel (at least together with beignet)?

Here an excerpt from clinfo:

  Device Name                                     Intel(R) HD Graphics Skylake ULT GT2
  Device Vendor                                   Intel

I also experienced this issue with clBLAS with Beignet on an Intel Skylake GPU. Let me know if any additional information is helpful.

Thanks. Do you know when the next release is planned?

I don't know for sure but next release will not be ever released in my opinion. Community has CLBlast with active maintainer (good job, @CNugteren ) and AMD has it's new rocBLAS to play with.
