x86_64-w64-mingw32-g++ 编译失败，g++ 工作正常

Question

我正在尝试在 linux 上交叉编译适用于 windows 的程序，但 mingw32 编译器出现 g++ 不存在的错误。

命令：

g++ *.cpp -o game -lGL -lGLU -lglfw -lftgl -lopenal -lalut -I/usr/include/freetype2

完美地编译程序。然而，mingw32 等效项（据我所知）输出以下错误：

    /usr/bin/x86_64-w64-mingw32-g++ *.cpp -o game.exe -I /usr/x86_64-w64-mingw32/include -L /usr/x86_64-w64-mingw32/lib -lGL -lglu -lglut -lglfw -lfreetype -lftgl -lopenal -lalut -I/usr/x86_64-w64-mingw32/include/freetype2

在我看来，mingw32 不喜欢 TEXT 类使用 OBJECT 构造函数的复制构造函数。我有几个类使用相同的格式并且不会引发错误。这可能是 ftgl.h 的问题，因为 TEXT 是唯一使用它的类，但这看起来太像语法错误了。

感谢任何/所有帮助。

在 Windows 上，TEXT 是一个宏函数，它告诉编译器在定义 UNICODE 时将传递给它的字符串作为 UTF-16 使用，否则作为 ANSI 字符串使用。由于预处理器在实际编译之前执行，它对您定义的类一无所知。它认为您正在调用宏函数，该函数只接受一个参数。这就是为什么它给你错误。重命名你的类来解决问题。
