Linux deployment to appimage, am I doing right?
-
I managed to cross compile and run app in both Windows and latest linux with Qt5. (QApplication desktop app)
And then I wanted to compile this on Ubuntu:jammy Linux desktop with Qt6 And succeed, but resulted in backward incompatible Appimage binary. (specific glibc shared object file not found error occured) I followed this instruction
After several tries with https://github.com/wheybags/glibc_version_header, Later I found on wiki that Qt6 needs glibc version at least >= 2.28
Should I just go back to still-supported oldest linux distribution with Qt5? Is it the only way to make backward-compatible Appimage binary?
