Problems building: nvcc fatal : Failed to preprocess host compiler properties.

[dscho15]

I'm trying to build the project, I'm running ubuntu 20.04, PyTorch 1.8.0 and Cuda 11.4.

At the fourth bullet point

cd $ROOT/lib/point_matching_loss
sudo python setup.py install

I get the following error:

nvcc fatal   : Failed to preprocess host compiler properties.

Not really sure how to fix it, anyone experiencing the same?

I think the problem is about your gcc. try if you have gcc on your machine
