I've had a couple issues building clBLAS so far today. I already had a problem where the build could not find the file ../clBLAS/src/library/blas/AutoGemm/UserGemmKernelSources/UserGemmClKernels.cc

I looked in the repo and saw that that file was generated by a python script, and I had the python script right there so I just ran it and that seemed to take care of the first error. However, this new issue seems to be related to the previous one somehow, but i'm not really sure how to proceed.

UserGemmClKernels.cc is in the repo here: https://github.com/clMathLibraries/clBLAS/blob/master/src/library/blas/AutoGemm/UserGemmKernelSources/UserGemmClKernels.cc

initUserGemmClKernels() is defined in that file. if you do a git status does it say that you are missing a file?

nathan-sixnines commented 8 years ago

Well that was fairly straightforward.

The file I had generated locally and the one in the repo were different, mine was missing that definition. I wonder how I lost that file to begin with.

TimmyLiu commented 8 years ago

Actually, I think you caught a bug. I just did some test if I do make clean, userGemmClKernels.cc is deleted. I think we need to modify somewhere in cmake so that this file is not treated as a generated file.

fixed by PR #213 in develop branch.
