I followed cocotb officials instructions to install package on windows with miniconda3 and :
conda install -c msys2 m2-base m2-make
but I'm blocked on this error :
(base) PS C:\Users\me> pip install cocotb

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for cocotb
Failed to build cocotb
ERROR: Could not build wheels for cocotb, which is required to install pyproject.toml-based projects
(base) PS C:\Users\me>
I tried with global option :
pip install --global-option build_ext --global-option --compiler=mingw32 cocotb
With exactly the same error.
It seems to be a verilator install error. I don't need verilator, maybe there is an option to not install it ?
I finally managed to install cocotb with following procedure on msys2.
$ pacman -Syu
[close then re-launch terminal]
$ pacman -Su
$ pacman -S –needed base-devel mingw-w64-x86_64-toolchain
$ pacman -S git
$ pacman -S mingw-w64-x86_64-ghdl-llvm
$ pacman -S mingw-w64-x86_64-gtkwave
$ pacman -S mingw-w64-x86_64-python-scipy mingw-w64-x86_64-python-matplotlib mingw-w64-x86_64-python-numpy
$ pacman -S --needed make mingw-w64-x86_64-gcc mingw-w64-x86_64-python3-pip mingw-w64-x86_64-python3-setuptools mingw-w64-x86_64-python3-wheel
$ pip install --no-build-isolation cocotb
$ pip install --no-build-isolation pytest
$ pip install --no-build-isolation cocotbext-axi
I tested this procedure on other windows computer with succes.
