如上图所示，我试图用cmake在QT Creator中编译一个QT5项目，并希望添加antlr包。

信息。Qt 5.12.8, Antlr 4.8, 编译器尝试过：mingw gcc Linux 都不能用。

为了包含Antlr 4.8，我使用提供的CPP包从源码中构建Antlr。

这是我正在做的项目。https:/github.comMrDiverArmSimulatortreeArmParsersrcasmeditorAsmEditor。

我将 antlr4 包括在下面 https:/github.comMrDiverArmSimulatorblobArmParsersrcasmeditorAsmEditorCMakeLists.txt#L14-L21。

通常情况下，当我用它编译一些东西时，它工作得非常好。但这次当我试图包含antlr的头文件时，我得到了这样的错误信息。

似乎很像它找不到。std::unique_ptr<Token> 但我不能改变很多，因为这些都是antlr的源头，而且它们确实在工作。

所以我真的不知道该从哪里寻找问题。如果我在设置中选择它为目标，库本身的编译也很好。

我尝试了什么。

• 在外面编译antlr库，然后把它链接到cmake文件中。
• 改变 Lexer.h 锉 #include <memory>.
• 在没有QT Creator的情况下编译QT项目(导致大量的错误，因为我无法让QT的链接工作)
• 在项目之外编译所有与Antlr相关的文件（没有QT也能完美工作，但不是我真正需要的）。
• 使用不同的编译器和不同的系统。
• 搜索问题与 moc 但似乎并不影响它。但我怀疑我在moc上看的不够仔细。

The problem is that Antlr has methods like "emit" that conflict with the Qt reserved word "emit". The solution is to disable the flag "no_keywords" (in qmake add

, and in CMake add

答案

. Then you must make the following conversions: 如果我不能用普通的cmake编译的话，那就太麻烦了。CONFIG += no_keywords谢谢你的帮助。add_definitions(-DQT_NO_KEYWORDS) 如上图所示，我试图在QT Creator中用cmake编译一个QT5项目，并想添加antlr包。信息。Qt 5.12.8, Antlr 4.8, 编译器尝试：mingw gcc。
