I tried rewriting the settings in different ways. This should work: "C:\msys64\ucrt64in\g++.exe" "%File%"
but it doesn't exe. There may be a discrepancy between these two programs. But it doesn’t matter, it’s quite enough to write the code in the editor and compile it separately. It's not critical, and I can work with this. -- <https://forum.pspad.com/read.php?2,78535,78537> PSPad freeware editor https://www.pspad.com
