make PythonAPI does not work on Windows 10

[xuyanwen2012]

Hello there,
My lab members and I have been stuck on this for many days already.
We are trying to build Carla on Windows 10 machines, and the CarlaUE4 actually runs ok. make launch works perfectly, and Unreal is working, and we can play it. However, when trying to make the PythonAPI, make PythonAPI, we have encountered many issues.

It is telling me Carla lib has been successfully installed but it is showing tons of linker errors. And I don't see any dist files been generated.

And I therefore could not run the example python scripts.

• I am using the x64 Native Tools Command Prompt for VS 2017
• I have Desktop Development with C++ && Windows 8.1 SDK checked
• I am using ```Python 3.7.6``

Does anyone have encountered similar situations before? Please advise what should I do next.

Thank you very much.

I'm also getting an error, although it's not the same.

Traceback (most recent call last): File "setup.py", line 131, in <module> ext_modules=get_libcarla_extensions(), File "setup.py", line 91, in get_libcarla_extensions libs = [x for x in os.listdir('dependencies/lib') if any(d in x for d in required_libs)] FileNotFoundError: [WinError 3] The system cannot find the path specified: 'dependencies/lib'

Could it be related?

I'm not sure if this exactly the issue, but it smells like it. See #1466.

The errors you show above smell specifically like errors with boost, although I'm not entirely sure what a fix for those would be.

@xuyanwen2012 I have the exact same issue. Have you found the solution yet?

Not yet, I am temporary getting around with this by switching to Linux (WSL). Although WSL have other issues that does not let me to launch the UE4editor, but at least the make PythonAPI can work. So I had my server running on Windows and the client running in WSL (kinda sucks, but at least it works).

Same here....seems like Windows was never built for driving simulator APIs :) ... possibly PACMan at the most.... Also, if we try the pypi version or the one that ships with the latest windows release i.e. carla 0.9.5 it throws the same "dependencies/lib" error..... made me believe I need to build it from scratch.. suffered miserably.... switched to linux instead...

Hi @xuyanwen2012 , I faced the same problem and managed to get around it. After compiling Carla client and server, instead of "make PythonAPI", I did:

cd PythonAPI/carla
python setup.py install

This generated the /dist folder and the ".egg" file within. I am able to run the .py examples now.
Hope this helps in your case.

Hi, I faced a similar issue recently, i solved the issue my opening the command prompt x64 Native Tools Command Prompt for VS 2017 with admin rights and followed steps mention in comment from @carfloresp ( path to carla\PythonAPI\carla and run python setup.py install)

@ixfd64 Its been a few years but did you find way to solve this?

I am still facing the dependencies error. The dependencies folder is still not created.

I don't remember the exact details as it's been a while. However, I think the issue went away for me after I pulled the latest code several months later.
