c++ - 如何解决mingw-w64 MSVCRT依赖问题

Question

我正在使用Go1.12 + msys2/mingw-w64(9.2.0)构建golang项目，它显示错误:

经过研究，我确定这是mingw64的msvcrt兼容性问题。
我知道有这样的解决方法: unresolved external symbol __imp__fprintf and __imp____iob_func, SDL2
但这并不能解决我所有的问题。

我尝试链接该库:LDFLAGS:-L％filepath％-llegacy_stdio_definitions，没有任何变化。

是否有补丁可以修复它，还是我必须构建自定义版本的mingw64？

Answer 1

因此，我本人回答了我的问题，此案已经结案。

是的，Mingw64使用msvcrt。

以下是一些技巧，可以帮助解决Mingw64和msvcrt之间的依赖关系问题。
主要目标是让编译器加载正确版本的MSVCRT库系列。

1.更新Mingw64。

2.在Mingw64 \ include_mingw.h(或x86_64-w64-mingw32 \ include)中 check out MSVCRT_VERSION ，确保版本号与您的Windows版本匹配或进行修改。

3.看看链接器选项，例如“#cgo LDFLAGS:-Lxxx”，不要弄乱库路径。删除任何不必要的库路径设置，让链接程序自行查找库。

确保所有内容都使用相同的库构建。
