如何从libgit2使用C头文件而不会出现此错误？ [英] How do I use C headers from libgit2 without getting this error?

问题描述

  #include<< p>< ; stdio.h中> 
 #include< repository.h> 
 
 int main（void）{
 puts（Hello，world！）; 
返回0; 
} 
  

当我使用GCC进行编译时，出现以下错误：

  maxwell @ UNIX-PC：〜$ gcc ok.c 
从/usr/include/common.h包含的文件中： 16：0，从/usr/include/repository.h:10获得
，从ok.c获得

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

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？

解决方案

为了记录，您应该使用构建系统来安装标题。这些头文件并不包含在内。如果你想使用libgit2，你应该包含 git2.h 。

I took everything from include/git2 to /usr/include, then tried compiling the following program:

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

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

When I compile this with GCC, I get the following error:

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,
                 from ok.c:2:

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

I see the error that says only to use inttypes.h only with Visual Studio, so how do I call repository.h from a program compiled with GCC? I really want to use some data structures defined in repository.h. Any idea what I am doing wrong?

解决方案

For the record, you should use the build system to install the headers. These headers aren't made to be included themselves. If you want to use libgit2, you should include git2.h.
