Created attachment 411004 [details, diff] Patch from upstream, fixes the problem. Patch taken from upstream Git repo works.
while the patch from upstream fixes the compilation problem I would guess from a first glance that the code will start leaking memory afterwards (release() called on an auto_ptr without deleting the object manually afterwards). I guess it is not a critical problem since the relevant code part is in a cli utility.

Is this due to hit the Portage tree soon? Current libclc will not compile for me without downgrading other packages.
*** Bug 562234 has been marked as a duplicate of this bug. ***
mesa-11.0.3 with USE="opencl" seems to require this package, and is thus unable to upgrade from my current mesa-11.0.0. I'm wondering if this is why my X server can't load nvidia's GLX module, but that's a different inquiry. The point is, there's a patch that seems at least somewhat functional, so here's my vote as well for getting this into the tree.
What is holding up this patch?
fixed in libclc-0.2.0_pre20151006
(In reply to Chí-Thanh Christopher Nguyễn from comment #8) > fixed in libclc-0.2.0_pre20151006 Confirmed; builds and installs on my machine.
