Windows support

[johndoe46]

Hello,

Thank you for your work on the python bindings of gmic.

Is Windows 64 support still on your radar ?

I can provide testing.

[myselfhimself]

Hello sorry for missing this, yes it is on my radar.. in the trimester if I do it myself. Otherwise I would need for someone who has Windows and is befriended with the MSVC compiler and Python's binary modules building, or who would accept me to lead her/him by a videoconference call or so, if he has Windows computer and is a tech person. Even the Windows virtual machine I had downloaded had a failing MSVC license... and I was short in available time back then..

Linked to #5

I'm not familiar with the MS build tools but they are installed on my system, so I guess I can execute whatever commands you need.

I can already send you the pip trace:

[myselfhimself]

Hello, clÿ: Ligne de commande warning D9002ÿ: option '-std=c++11' inconnue ignor‚e this is enough to require MSVC knowledge as it would imply that the setup.py file should have specifities for Windows...

I need to see how frequent libgmic static objects are released.. it could spare a lot of work...

[myselfhimself]

Just asked for advice on the related pixls.us thread.

Hello @johndoe46 , I have private feedback from some who managed to have gmic-py for Linux working on Windows thanks to WSL (Windows subsystem Linux) and optionnally windowed display works if https://sourceforge.net/projects/vcxsrv/ is installed. Would you like to go on this way while waiting for someone to release gmic-py for Windows?

Simple question... is gmic-py support for libopenCV a MUST for you?

[johndoe46]

Hello @myselfhimself ,

Thanks for the feedback.

Yes, WSL (version 2) is good and I use it for development needs, however it's not something that is installed out of the box on all windows pcs, so we can't count on it for software distribution. (on a side note, MS is currently adding support for graphic apps: https://www.pcworld.com/article/3543763/windows-10-moves-closer-to-true-linux-with-graphical-support-for-wsl2.html ).

gmic-py libopencv support is probably not a must for us.

We're not in a hurry anyway, I just think gmic+python is an incredible opportunity for imagery software in general and should see a wide adoption (which means win64 support).

Thank you for your time.

[myselfhimself]

OK !! yes it is good to strategize this way! And yes WSL2 looks much nicer..

For info someone in my network uses libopencv + gmic-py numpy support + gmic-py + wsl, feel free to tell me if you would like me to put you through to that person Have a nice day!

Hi, i'm not very experienced in programming, but I in high need of gmic implementation in python code for windows desktop application. By forum and git discussions it looks like possible, but I have no idea how. Can you advice me any way to dig into?

[myselfhimself]

Hello @Elessar11777 I recommend you use WSL or WSL2 (Ubuntu on Linux.. ie. windows subsystem) and run pip install gmic in the Linux shell. gmic-py was never successfully compiled for Windows, it is not impossible but not done. If you have development skills and Visual Studio for C++ development on Windows this can be tried but can take maybe 8-16 hours together by shared screen on week-ends...

[myselfhimself]

On https://gmic.eu/download.html see the Src - Windows paragraph G'MIC compiles well with Msys2

[myselfhimself]

With msys2 you will need python headers and libs, possibly from the python msys2 pacman packages: https://packages.msys2.org/search?t=pkg&q=python (python or mingw-w64-python)
