    I used the -avx parameter when configuring and compiling the qt source.
    Compiling succeeds.
    However, after making .exe file,when executing it.
    It prompts:

    Incompatible processor. This Qt build requires the following features:
    Avx avx2
    Aborted. Incompatible processor: reminder of missing feature 0x8400-avx

    How should I solve this problem?
    I'm using an open source license.
    Does it have anything to do with licenses?

      @smallcsduck Does your CPU support AVX/AVX2?

              @smallcsduck Is it possible that AVX is disabled in your BIOS/UEFI?

                Apart form this - what do you think you will gain from compiling for AVX only?

                  I like to explore.
                  I certainly want to give this a try.
