Hi,
We have run all the tests in libDAI 0.3.2 and no errors were found.
We also didn't change anything in makefiles and just followed the instructions as prescribed in the documentation.
But when we try to compile example_imagesegmentation.cpp under the examples folder, we get this error:
How can we fix this?
