while building QT 6.1.0 for Windows I got the following compiler error:

@Dmitriano said in Compiler errors while building QT 6.1.0 for Windows:
E:\PFiles\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin\c++.exe
As you can see the gcc compiler is picked up. Make sure it's not in your PATH and the MSVC development environment is properly set up (vsvars.bat etc.) so configure.bat is using MSVC instead gcc.
Why do you want to compile Qt by yourself? -

Why do you want to compile Qt by yourself?@Christian-Ehrlicher I compile QT by myself because I prefer QT with -DQT_NO_EXCEPTIONS=1, it disables try/catch block surrounding QThread's loop.
I removed MinGW from the PATH and looks like it started to build.
