x86_64-w64-mingw32-g ++编译失败，g ++正常工作

Question

I'm trying to cross-compile a program for windows on linux, but the mingw32 compiler is getting errors that aren't present with g++.

the command:

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

compiles the program perfectly fine. However the mingw32 equivalent (as far as I can tell) outputs the following errors:

    /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

It looks to me that mingw32 doesn't like the copy constructor where the TEXT class is using OBJECT's constructor. I have several classes that use the same format and don't raise errors. It might be a problem with ftgl.h, because TEXT is the only class that uses it, but this looks too much like a syntax error.

any/all help is appreciated.

Answer 1

On windows, TEXT is a macro function that tells the compiler to use the string passed to it as UTF-16 when UNICODE is defined, and as an ANSI string otherwise. Since the preprocessor is executed before the actual compilation, it knows nothing of the class you defined. It thinks you are making a call to the macro function, which accepts just one argument. This is why it's giving you the error. Rename your class to solve the problem.
