qtdeclarative: failure to build JIT compiler on X32 ABI

    XMLWordPrintable

Details

    • Linux/X11

    Description

      X32 ABI is an ABI for X86_64 that uses 32bit-long pointers while operating in long mode (64bit registers etc).

      QtDeclarative fails to build JIT with the following build error:
