Compilation failed on Windows and Mingw

I'm trying to compile pbrt-v4 on windows using Mingw, I got this error:

I'm sorry, I've only now noticed the previous issue. https://github.com/mmp/pbrt-v4/issues/297

Assalamu alaykum. Hey bro, can you share with me your compiled build for windows?

[MoamenAbdelsattar]

وعليكم السلام ورحمة الله وبركاته yes sure, but I'm getting another error probably due to corrupt installation of min-gw. I've got exams to study for and I can't find enough time to fix the error, so give me few days, sorry for that. Also please note that I'm building without gpu support because I don't have Optix installation.

Oh, no problem but unfortunately I need CPU/GPU build for my addon for Blender.

[MoamenAbdelsattar]

Good luck, but if you are going to distribute an addon, you should NEVER take the build from someone else. You should build pbrt yourself. The build from someone else can be malicious, and you will be responsible for any harm happening to the users of your addon.
