我将所有内容从 include/git2 带到 /usr/include，然后尝试编译以下程序：

#include <stdio.h>
#include <repository.h>

int main(void) {
    puts("Hello, world!");
    return 0;
}

当我用 GCC 编译它时，我收到以下错误：

maxwell@UNIX-PC:~$ gcc ok.c
In file included from /usr/include/common.h:16:0,
                 from /usr/include/repository.h:10,
                 from ok.c:2:

                 from /usr/include/repository.h:10,

/usr/include/inttypes.h:284:11: error: unknown type name ‘__cdecl’

我看到错误说只能在 Visual Studio 中使用 inttypes.h，那么如何从使用 GCC 编译的程序中调用 repository.h？我真的很想使用 repository.h 中定义的一些数据结构。知道我做错了什么吗？

当您将所有内容从 include/git2 复制到 /usr/include 时，似乎某些头文件被覆盖了。

In file included from /usr/include/common.h:16:0,
                 from /usr/include/repository.h:10,
                 from ok.c:2:
/usr/include/inttypes.h:33:2: error: #error "Use this header only with Microsoft Visual   C++ compilers!"

正确的方法是使用 gcc 的-Iinclude_path选项来包含其他头文件，并使用“-D macro_def”来定义要与预处理器一起使用的宏。

gcc -I repository_h_path  -D some_macro  ok.c

您可能需要参考 gcc 文档中的搜索路径。

作为记录，您应该使用构建系统来安装标头。这些标头本身不会被包含在内。如果你想使用 libgit2，你应该包括git2.h.
