构建SFML和V8 我试图用SFML作为C++游戏引擎的图形主干。我也在使用V8 JavaScript引擎。问题是，要让V8编译，我必须使用-stdlib=libstdc++，要让SFML编译，我必须使用-stdlib=libc++。显然，我不能同时使用这两种方法，那么我如何解决这个问题呢

顺便说一句，我在MacMini上使用Xcode，但它也不能通过终端工作

使用

-stdlib=libstdc++

时，SFML会给我这些错误：

当使用

-stdlib=libc++

时，V8会给我这些错误：

您需要使用相同的std库重新编译SFML和/或V8，因为它们不兼容。我不知道是否适用于V8，但SFML也应该能够与libstdc++一起工作（在生成makefile时，将

CMAKE_CXX_标志

和

CMAKE_C_标志

设置为

-stdlib=libstdc++

）。但是，您将无法在libstdc++中使用C++11特性
