当我试图编译libburn中的测试文件夹时，Gcc抛出错误

Question

Libburn

所以，在我安装了libburn之后，我转到了与libburn代码一起提供的测试文件夹。然后是libburner.c文件。我试图用gcc(gcc-libburn.c-o outputfile(编译它，但即使头文件存在，它也会给我这些错误。

请帮帮我。

在C:中创建软件时，通常会涉及到三种工具

1. 一个编辑器来编写源代码
2. 一个编译器，用于将源代码转换为目标代码，目标代码主要由机器代码组成，其引用尚未解析
3. 链接器，用于将目标代码的分离部分链接(绑定(到可执行文件中，该可执行文件已解析所有引用

您可以将任何应用程序用作编辑器，以创建正确格式的源代码。我甚至听说有人用微软Word做这个，因为当时的记事本无法处理大于64KB的文件。

您显然将GCC用作编译器和链接器。

你没有提到任何编译问题，它显然没有报告任何错误。无论如何，测试应用程序的源代码包含行#include "libburn.h"或类似内容。通过这种方式，编译器知道应用程序可以调用某些函数，并且可以检查应用程序是否以正确的方式不调用这些函数。

您写道要构建的命令行是gcc libburn.c -o outputfile，我认为这是错误的。应该是gcc libburner.c -o outputfile。

此命令行缺少指向库libburn的链接的参数。因此，链接器报告了许多"未定义的引用"。

将-lburn添加到命令行，或者添加其他合适的内容。您也没有提到构建的主机和目标系统，这取决于具体情况。

注意：命令行同时包含两个步骤：编译和链接。请花一些时间研究并学习如何从命令行使用GCC
