Is building from source for linux still working

[ghost]

Im very new with linux so you'll have to bear with me if I've done anything very wrong.
I've been following the HowToBuild.md but i'm getting errors while trying to build.
I tried the "for QTCreator" and "for command line builders" but they both gave a bunch of errors, here is the QTCreator output

My build steps are

and I use ctrl+b to build
I've commented out DEFINES += QV_WITHOUT_OPENGL and DEFINES += QV_PORTABLE in QVproject.pri

I've never seen this compilation error. I think it's probably due to the gcc version rather than the Linux version. I think it is effective to add a compile option to prevent error detection or lower the version of gcc.

If you know how to fix the source code to prevent this compilation error, please send me a pull request :)

What environment used for 1.1.1?
Got same error when tried to build with Ubuntu 20.04 default qt5 installation from repositories.
