Comment (by LigH):
Following this suggestion, I got a new library installed, but the issue
persists for me.
This libOpenCL.a contains symbols clCreateImage3D(@44) and
clCreateImage2D(@36), but not clCreateImage(@28) alone (one of the symbols
reported as missing while trying to link avutil-56.dll).
The OpenCL.def used does not contain this export either. Snippet from the
header (whole file will be attached):
{{{
;
; Definition file of OpenCL.dll
; Automatic generated by gendef
; written by Kai Tietz 2008
;
}}}
Is this content specific to my hardware? If so, maybe that's the reason
why my build is not as hardware independent as expected?
