Qt5 C++ application compilation from prompt
-
Try to use these commands:
qmake -makefile
mingw32-make
"./release/app".pro
QT += core gui widgets CONFIG += c++11 SOURCES += \ main.cpp TARGET = appIt works with Qt6. Perhaps this will work with Qt5.
Edited 1/12/2023. Added

qmakecommand that built this makefile is expectingg++to invoke version 7.3 64Bit and link against Qt libraries built with GCC 7.3 64Bit.
It is possible that GCC 7 and GCC 8 libraries are binary incompatible (do not know, haven't looked) and thisnis the cause of the link-time issue.Try:

Would you mind to provide more information or how are others supposed to help you based on that information?

@8Observer8
OK.
undefined reference@Robert-M, сould you show your current .pro file in full?

@Robert-M Have you tried forcing the correct compiler/linker as I requested a few days back?
