c++ - 在 QtCreator 中链接 SDL2

Question

所以我想使用 Qt 作为我的 SDL 应用程序的编辑器。当我尝试在 Qt 中创建一个空白项目并链接库时，它就是找不到 SDL2/SDL.h。这是我的 .pro 文件中的内容:

mac: LIBS += "-F$$PWD/../Control Libraries/" -framework SDL2
INCLUDEPATH += "$$PWD/../Control Libraries/SDL2.framework/Versions/A/Headers"


mac: LIBS += "-F$$PWD/../Control Libraries/" -framework SDL2_mixer
INCLUDEPATH += "$$PWD/../Control Libraries/SDL2_mixer.framework/Versions/A/Headers"


mac: LIBS += "-F$$PWD/../Control Libraries/" -framework SDL2_ttf
INCLUDEPATH += "$$PWD/../Control Libraries/SDL2_ttf.framework/Versions/A/Headers"

我找不到任何人发布如何让它工作，但我知道必须有一些方法。它只需单击一下即可在 Xcode 中运行，所以我只是做错了什么吗？谢谢。

错误信息如下:

编辑:我已经得到它所以我可以包括，但不是，这是一个问题，因为 SDL 混合器和 SDL rtf 都使用

当路径中有空格时，您应该使用双引号，例如:

INCLUDEPATH += "$$PWD/../Control Libraries/SDL2.framework/Versions/A/Headers"

除非你确实希望它们是单独的参数，例如:

mac: LIBS += "-F$$PWD/../Control Libraries/" -framework SDL2_mixer

问题编辑后:所以你有 #include <SDL2/SDl.h> .好像大小写错了，应该是

#include <SDL2/SDL.h>
