About using SiftGPU with cuda

[flymaxty]

Hi,
I found that if I want to use siftgpu with cuda, I have to comment the following line in siftgpu's makefile
siftgpu_enable_cuda = 0 (line 17)
but the doc did not say that. Is there something wrong for my steps? or you just forget to comment it? :)

That's a bug. I forgot to take this out after changing the test in line 11. Didn't notice, since I don't use cuda. I'll throw the line out, thanks.

Ok, fixed in indigo and hydro branches.

Thank you for your quick reply! :)

Oh, there's other problem I forgot to say, in x64 platform, the following line has a little problem:
simple_find_cuda = $(shell locate /usr/local/cuda/lib/libcudart.so*)
the libs is in /usr/local/cuda/lib64/ not /usr/local/cuda/lib/ in x64 platform.

Hi flymaxty. I couldn't find a sensible way to check for cuda. The current way didn't work and the out-of-the-box build fails if cuda isn't installed. I therefore now disabled cuda in siftgpu's makefile. I am afraid this will interfere with your setup, but should be easy to fix for you: just change "siftgpu_enable_cuda = 0" to "... = 1" in line 11 of the mentioned makefile.
