如何在不收到此错误的情况下使用libgit2中的C头文件？

Question

我把所有东西从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:

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

我看到的错误仅表示只使用Visual Studio中的inttypes.h,那么如何从使用GCC编译的程序中调用repository.h？我真的想使用repository.h中定义的一些数据结构.知道我做错了什么吗？

当您将include/git2中的eveything复制到/ usr/include时,似乎会覆盖一些头文件.

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

您可能希望在gcc文档中引用搜索路径.
