on detecting OpenCL compute capability

[Ghislain Vaillant <ghisvail@gmail.com>]

Hi all,

I have been packaging a few OpenCL libraries lately. For most of them, 
the test suite can only be run from an OpenCL capable machine.

Do we have an "official" mean to detect OpenCL compute capability within 
d/rules? I saw an example in ViennaCL where a small program is compiled 
for that purpose, but that sounds more like a hack to me.

How about using the clinfo utility for this purpose? Has anyone tried 
detecting OpenCL compute capability with it?

Best regards,
Ghis
