[Solved] Failure building wheel, even with g++

[Jarelk]

Our team is running into trouble installing lap in Docker (using nvidia/cuda:10.1-cudnn7-runtime-ubuntu18.04 as base image). Even with g++ installed.

Here is the log for g++ --version:

#9 0.520 g++ (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0 #9 0.520 Copyright (C) 2017 Free Software Foundation, Inc. #9 0.520 This is free software; see the source for copying conditions. There is NO #9 0.520 warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Log of install failure attached.

Thanks for the report. Could you provide the Dockerfile to make it easier to reproduce the error? The base image above does not provide g++, python and any of the python dependencies.

Thank you for taking the time. I've rewritten these a bit for readability, but these should still reproduce the bug (I tested it).

I build the image using the command line docker-compose -f docker-compose.yml build

Thanks, the build is missing python headers:

...
#17 122.1   lap/_lapjv.cpp:4:10: fatal error: Python.h: No such file or directory
#17 122.1    #include "Python.h"
#17 122.1             ^~~~~~~~~~
#17 122.1   compilation terminated.
...

Adding the headers to your dockerfile should solve it:

apt install python3.8-dev

Let me know if this helped.

That fixed it, thank you!
