OS: Windows 10
IDE: Visual Studio 2015
I need to use the AsmJit library (https://github.com/asmjit/asmjit) inside my Qt GUI Application. But is is somehow incompatible. When certain headers are included from QT (QWidget etc.), things start to break.
Most errors originate from this line:
ASMJIT_INLINE Error emit(uint32_t code, const Operand& o0, const Operand& o1, const Operand& o2, const Operand& o3) {
return _emit(code, o0, o1, o2, o3);
}
Where ASMJIT_INLINE is defined as __forceinline.
When I compile it in VS2015, it is giving the following error:

After thinking about this I think the only reason that asmjit doesn't compile with Qt is that qt defines emit macro, which collides with asmjit's emit function. So after expanding the macro the code:
ASMJIT_INLINE Error emit(uint32_t code,
const Operand& o0,
const Operand& o1,
const Operand& o2,
const Operand& o3) { return _emit(code, o0, o1, o2, o3); }
Becomes:
ASMJIT_INLINE Error (uint32_t code,
const Operand& o0,
const Operand& o1,
const Operand& o2,
const Operand& o3) { return _emit(code, o0, o1, o2, o3); }
Using Qt with 3rd Party Signals and Slots (https://doc.qt.io/qt-5/signalsandslots.html) mentions it:
no_keywordstells Qt not to define the moc keywords signals, slots, and emit, because these names will be used by a 3rd party library, e.g. Boost. Then to continue using Qt signals and slots with the no_keywords flag, simply replace all uses of the Qt moc keywords in your sources with the corresponding Qt macros Q_SIGNALS (or Q_SIGNAL), Q_SLOTS (or Q_SLOT), and Q_EMIT.
Adding no_keywords to Qt project is the same as passing -DQT_NO_KEYWORDS to the compiler (basically defining QT_NO_KEYWORDS to 1).
This could be fixed on asmjit side as well, however, asmjit is doing nothing wrong. You would have the same problem with many other libraries like boost.
