Question

我从include / git2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;
}

当我使用GCC编译时，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。知道我做错了吗？

Answer 1

当您从include / git2复制eveything到/ usr / include时，似乎覆盖了一些头文件。

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

您可能需要在gcc文档中引用search path。

Answer 2

对于记录，您应该使用构建系统来安装标头。这些标题不会自己包含在内。如果你想使用libgit2，你应该包括git2.h。

如何在不收到此错误的情况下使用libgit2中的C头文件？
