我想安装 OpenCV 2.1.0（在 Ubuntu 11.10 上），但是在 make 之后（我在 make 之前的步骤：http: //www.doc.ic.ac.uk/~strasdat/rss2010videos/INSTALL.txt）我得到：

make: *** [all] Chyba 2
我在 cvcap_ffmpeg.cpp 文件中添加了这个：
#ifndef UINT64_C
#define UINT64_C(c) (c ## ULL)
#endif
#if LIBAVCODEC_VERSION_MAJOR < 53
#define CodecType AVMediaType
#define CODEC_TYPE_UNKNOWN AVMEDIA_TYPE_UNKNOWN
#define CODEC_TYPE_VIDEO AVMEDIA_TYPE_VIDEO
#define CODEC_TYPE_AUDIO AVMEDIA_TYPE_AUDIO
#define CODEC_TYPE_DATA AVMEDIA_TYPE_DATA
#define CODEC_TYPE_SUBTITLE AVMEDIA_TYPE_SUBTITLE
#define CODEC_TYPE_ATTACHMENT AVMEDIA_TYPE_ATTACHMENT
#define CODEC_TYPE_NB AVMEDIA_TYPE_NB
#endif
它解决了之前的一些问题。
我尝试像这里一样安装 ffmpeg -> https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide，但它没有改变。有人可以帮我解决这些错误吗？
感谢
