获取“字段具有不完整类型”和“冲突类型” [英] Getting “field has incomplete type” and "conflicting types"

问题描述

我正在尝试从源代码构建pjsip，并在ubuntu上由gcc支持视频。当我成功完成运行./configure并使dep，我运行make，我有错误以下：

  ../ src / pjmedia / ffmpeg_util.c：46：18：error：field'codec_id'has incomplete type 
 ../src/pjmedia/ffmpeg_util.c:148:13：error：冲突类型为'pjmedia_format_id_to_CodecID'
 ../src/pjmedia/ffmpeg_util.h:23:13：注意：以前的声明'pjmedia_format_id_to_CodecID'在这里
 ../src/pjmedia/ffmpeg_util.c：在函数'pjmedia_format_id_to_CodecID'中：
 ../src/pjmedia/ffmpeg_util.c:154:35：警告：[默认启用]指针和整数之间的比较
 ../src/pjmedia/ffmpeg_util.c:155:6：错误：解除引用指针到不完整的类型
 ../src/pjmedia/ffmpeg_util.c:155:6：warning：语句没有影响[-Wunused-value] 
 ../src/pjmedia/ffmpeg_util.c:160 ：5：error：取消引用指向不完整类型的指针

 ../src/ pjmedia /的ffmpeg _util.c：在顶层：

解决方案

看起来你看到的大多数错误根植于事实枚举CodecID 未找到。不确定您的来源可能在哪里，但此提交讨论将其重命名为 AVCodecID 。你确定你有最新的来源吗？

解决方案

Looks like most of errors you are seeing are rooted in the fact enum CodecID is not found. Not sure where it might be in your source, but this commit discusses renaming it to AVCodecID. Are you sure you have an up-to-date source?
