Windows compilation error

[zanxueyan]

The following error occurs when the last step of make-j12 is executed:
`MINGW64 /d/webots

make -j12

Makefile:58: pwd -W | tr -s / '//'/resources/Makefile.os.include: No such file or directory
make: *** No rule to make target 'pwd -W | tr -s / '//'/resources/Makefile.os.include'. Stop.
`
What should I do? Please give guidance, thank you!

Did you follow precisely the instructions from https://github.com/cyberbotics/webots/wiki/Windows-installation/?

[zanxueyan]

Yes,I follow the documentation steps exactly until I get an error as shown in the figure

[zanxueyan]

Since I am not familiar with Linux, I would like to use Visual Studio for debugging and compilation under Windows.Can I achieve this result?

[omichel]

Unfortunately, we do not use Visual Studio to compile Webots. Instead, we use gcc (which comes with MSYS2 on Windows). But it is possible to compile robot controllers using Visual Studio.

Thanks

[zanxueyan]

I operated according to the steps again, and there was no mistake last time, but there was a new mistake

[zanxueyan]

Modified the code in generate Proto list.py as shown below，OK

Strange, this not needed on my computer. May I ask you to type "which python" and "python -VV" to determine which version of python your are using?

[zanxueyan]

python -VV

Python 3.10.5 (main, Jun 18 2022, 01:16:30) [GCC 12.1.0 64 bit (AMD64)]

[zanxueyan]

python -VV

Python 3.10.5 (main, Jun 18 2022, 01:16:30) [GCC 12.1.0 64 bit (AMD64)]

[omichel]

May I ask you also to give me the output of the following:

printenv LANG
printenv LC_CTYPE

I have:

LANG = en_US.UTF-8
LC_CTYPE = en_GB.UTF-8

Also, can you try to set:

export PYTHONIOENCODING=UTF-8

before you start the script?

I had this error before, it seems to happen when you dont source https://github.com/cyberbotics/webots/blob/master/scripts/install/bash_profile.windows within mingw.. I still dont understand why

[omichel]

That is likely because the bash_profile.windows is calling in turn https://github.com/cyberbotics/webots/blob/master/scripts/install/msys.sh which changes the PATH environment variable to include the msys2 binaries ahead of the default windows binaries.

[omichel]

The problem should be fixed in #4982.
