We used openMVG to run SFM, and transformed its output into openMVS. But we have met a problem as following: pic I saw there are some similar problems in the "issues"，but i still can't find a way to solve it. Can anybody help me? I will be very grateful.

It seems like OpenMVS was not compiled with JPEG support. Make sure you point CMake to the JPEG library during OpenMVS configuration.

Thanks for your solution, but why i can't find the "JPEG" choice in cmake? How to point cmake to the JPEG library?

In fact,I can't find the jpeg library during OpenMVS configuration,either.So I have trapped by this problem for a week.I will be very grateful if you can offer a more detailed answer!!

Is JPEG_INCLUDE_DIR and JPEG_LIBRARY defined in your CMakeCache?

This may not be the exact issue raised my the OP but there is a problem with the code only recognising .jpg and not.jpeg extensions which was the reason i was getting a bunch of different errors. libs/IO/Image.cpp just needs a small change to recognise both file extensions.

I cross posted a similar response to one of the other open issues related to similar errors which may have been caused by this specific problem.
