pythonocc-core installation issue

[sohertz]

Hello, I am currently installing pythonocc but face several issues. I am following the INSTALL instructions (https://github.com/tpaviot/pythonocc-core/blob/master/INSTALL.md)

I crate a local copy of the repository, create the "cmake-build" folder and proceed to the first "cmake"

D:mypath> cd pythonocc-core D:mypath\pythonocc-core> mkdir cmake-build D:mypath\pythonocc-core> cd cmake-build D:mypath\pythonocc-core\cmake-build> cmake ..

I got lots of VC++ Project Filters in the pythonocc-core folder. And then, I cannot find how to make the command line "make and make install" work properly (I launch cmd with administrator rights) but get always the same message:

D:mypath\pythonocc-core> make

mingw32-make.exe: *** No targets specified and no makefile found. Stop.

I also saw that this Cmake File exists: cmake_install but there is actually no Makefile that could be a target for the make line. Do you have any idea what went wrong and how to solve that? Any advice would be very helpful, thank you for your attention.

see https://github.com/tpaviot/pythonocc-core/blob/master/ci/conda/bld.bat , it's the way pythonocc-core is built on windows, using ninja

The installation.md may not be up to date, sorry

Thank you for your reply. So I installed ninja and used the command line in the cmd prompt. I got following message:

Configuring incomplete, errors occurred! See also "D:/IfcOpenShell-master/deps-vs2017-x86-installed/Python34/Lib/pythonocc-core/build/CMakeFiles/CMakeOutput.log".

Do you know how I could fix this? Is it possible to add some arguments in the request?

I had the same issue with Python 3.6. Could not find Python3 after I installed Python 3.6 to C:\Program Files\Python3
