Running tests with CMake #28
Description
NOTE: Building with CMake still works fine - only the tests are affected.
As I discovered while testing #26, there is some sort of CMake bug in NVcaffe.
Sometimes, when you build with CMake and try to make runtest, you get thousands of lines of errors. The errors seem to occur intermittently - I've tried v0.12.*, v0.13.*, with/without cuDNN, with/without CNMeM, with/without parallel build (make --jobs=4), etc. I think this only happens when Caffe is using CUDA.
Unfortunately, the Caffe TravisCI build doesn't actually build the tests when using CUDA and CMake (see here and here).
How to reproduce
mkdir build
cd build
cmake ..
make all runtestError
Sometimes the tests build and run without a hitch. More often, CMake dumps thousands of lines of output. I'm not sure what's relevant, but here are the first 20 lines and the last 20 lines:
