我从include / git2到/ usr / include，然后试着编译下面的程序：
#include <stdio.h> #include <repository.h> int main(void) { puts("Hello, world!"); return 0; } 当我用GCC编译这个时，我得到以下错误：
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:33:2: error: #error "Use this header only with Microsoft Visual C++ compilers!"

我发现只有在Visual Studio中才使用inttypes.h的错误，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。 任何想法我做错了什么？
为了记录，您应该使用构建系统来安装标题。 这些头文件不会被包含在内。 如果你想使用libgit2，你应该包括git2.h
当你从include / git2复制到/ usr / include时，似乎有些头文件被覆盖。
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!"
正确的做法是使用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
