I'm trying to build OpenCASCADE 7.7.0 using adm/qmake/OCCT.pro, which is not shown in document
and I have such complie problem:
cd FoundationClasses\ && ( if not exist Makefile D:\QT\qt-5.15.2-x64\5.15.2\mingw81_64\bin\qmake.exe -o Makefile D:\OpenCASCADE-7.7.0-vc14-64\opencascade-7.7.0\adm\qmake\FoundationClasses\FoundationClasses.pro -spec win32-g++ "CONFIG+=debug" "CONFIG+=qml_debug" ) && D:/QT/qt-5.15.2-x64/Tools/mingw810_64/bin/mingw32-make -f Makefile

How do I resovle it ?

The current version of qmake scripts considers only Visual Studio compiler on Windows platform (hense, -EHa flag passed to compiler). So that you will need tuning scripts (win32 branches) for handling Mingw-w64 / gcc on Windows platform.
