warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings]

比如 char* what() const { return "Wind"; }

会有：

[Warning] deprecated conversion from string constant to
'char*' [-Wwrite-strings] char* what() const { return "Wind"; }



改成：

const char* what() { return "Wind"; }

就好了。

只要在编译的时候加入一个参数就可解决：

g++ -Wno-write-strings main.cc

如果是 Android NDK 编译警告可以再 Android.mk 文件加入一行：

LOCAL_CPPFLAGS += -Wno-write-strings
