一、环境
1、操作系统版本
CentOS 6.2 64位
uname -a的输出：
Linux localhost.localdomain 2.6.32-220.17.1.el6.x86_64 #1 SMP Wed May 16 00:01:37 BST 2012 x86_64 x86_64 x86_64 GNU/Linux
版本：1.6.1
下载链接：
~ahze/distfiles/mpeg4ip-1.6.1.tar.gz
二、编译
1、编译mpeg4ip需要的库
yum install libtool
然后进入到mpeg4ip的目录，运行./bootstrap进行配置，如果出错，是因为bash版本及名称的问题，修改bootstrap文件中第一行，改sh 为bash.或运行 bash ./bootstrap。
提示如下：
*** ffmpeg encoder is not installed*** xvid encoder is not installed*** x264 encoder is not installed*** lame encoder is not installed*** faac encoder is not installed*** twolame encoder is not installed
安装相应库：
yum install ffmpeg-devel xvidcore-devel twolame-devel x264-devel
编译：make
2、编译中的错误处理
2.1 报错内容：
In file included from config_opts.cpp:1:/include/mpeg4ip.h:126: error: new declaration ‘char* strcasestr(const char*, const char*)’/usr/include/string.h:369: error: ambiguates old declaration ‘const char* strcasestr(const char*, const char*)’
解决办法：
vi include/mpeg4ip.h
注释掉函数声明，如下所示：
2.2 报错内容：
cc1plus: warnings being treated as errorssys_decoder_blkdec.cpp:190: error: suggest parentheses around ‘&&’ within ‘||’sys_decoder_blkdec.cpp:205: error: suggest parentheses around ‘&&’ within ‘||’
如图所示：
解决办法：
vi common/video/iso-mpeg4/src/Makefile
去掉Werror
vi命令：%s/-Werror//
2.3 报错内容：
type_basic.cpp:320: error: ‘<anonymous>’ has incomplete typetype_basic.cpp:320: error: invalid use of ‘Void’type_basic.cpp:320: error: prototype for ‘Void CMotionVector::setToZero(<type error>)’ does not match any in class ‘CMotionVector’./../include/basic.hpp:441: error: candidate is: Void CMotionVector::setToZero()
解决办法：
vi common/video/iso-mpeg4/src/type_basic.cpp
2.4 报错内容：
cc1: warnings being treated as errorsconfig.c: In function ‘enter_chn’:config.c:636: error: array subscript is above array boundsconfig.c:637: error: array subscript is above array bounds
解决办法：
vi player/lib/audio/faad/Makefile
去掉Werror
2.5 报错内容：
/usr/local/include/libavutil/common.h: In function ‘int32_t av_clipl_int32(int64_t)’:/usr/local/include/libavutil/common.h:154: error: ‘UINT64_C’ was not declared in this scope…
解决办法：
涉及到标准c和c99的问题，在出问题的文件中加上下面三句话就好了
#ifndef UINT64_C#define UINT64_C(value)__CONCAT(value,ULL)#endif
重新开始吧!下次我会吸取教训，不让自己犯同样的错误的;
