[英]Conflicting typedefs when cross compiling for windows on linux
I am trying to cross-compile an application for Windows using MinGW-w64.我正在尝试使用 MinGW-w64 交叉编译 Windows 的应用程序。 My project uses GLFW and the error seemed to have come from it.
我的项目使用 GLFW,错误似乎来自它。
Here is part of the compiler output:这是编译器 output 的一部分:

I have done some research online and found out that the error was caused by MinGW-w64 including the native Linux headers.我在网上做了一些研究,发现错误是由 MinGW-w64 引起的,包括本机 Linux 标头。 However, I checked the CPLUS_INCLUDE_PATH mentioned in one of the sources I found, and it was empty.
但是,我检查了我发现的其中一个来源中提到的 CPLUS_INCLUDE_PATH,它是空的。 And there's not much else I can find about this problem.
关于这个问题,我找不到太多其他信息。
What can I try and do here to solve the problem?我可以在这里尝试做什么来解决问题? Thanks in advance.
提前致谢。
Additional information:附加信息:
I'm using CLion as my IDE and it uses CMake. To make it cross-compile for Windows I changed the C and C++ compilers specified in the 'toolchains' settings like so:我将 CLion 用作我的 IDE,它使用 CMake。为了使其针对 Windows 进行交叉编译,我更改了“工具链”设置中指定的 C 和 C++ 编译器,如下所示:
I've solved the problem by creating a CMake toolchain file that looks like this我通过创建一个如下所示的 CMake 工具链文件解决了这个问题
# the name of the target operating system
set(CMAKE_SYSTEM_NAME Windows)
# adjust the default behavior of the FIND_XXX() commands:
# search programs in the host environment
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
# search headers and libraries in the target environment
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
