error C2248 when run python setup.py install

[JunHill]

Hi, I'm facing an issue with building the simulator in Windows 10. After cloning the git repo, I installed Python dependencies with conda as instructed:

conda env create -f environment.yml

Then I ran the following command to build the simulator:

python setup.py install

and end up with this error:

subprocess.CalledProcessError: Command '['cmake', '--build', '.', '--config', 'Release', '--', '/m']' returned non-zero exit status 1.

I scrolled up a bit and see the following lines in red:

Have you run conda activate evogym before running python setup.py install? Also, do you have cmake installed beforehand on your machine?

[JunHill]

yes and yes.

I installed cmake with:

pip3 install cmake

after it said that i didn't have one

[jagdeepsb]

I think that might not be sufficient. I'd recommend installing cmake here and then adding C:\Program Files\CMake\bin (or the relevant directory) to your path variable.

[jagdeepsb]

Sorry I take that back, it seems like you can run cmake from the terminal. Another potential issue: are you using the 2017 version of Visual Studio Build Tools? The 2019 version in particular is currently not supported.

[JunHill]

Thank you for your quick reply! I was using the version 2019 of VS build tools. After changing VS build tools to 2017 version and deleting the caches in the build folder, I can now install the simulator and run gym_test.py.
