#linux #c

本文解决在使用libavutil/common.h头文件时遇到的UINT64_C宏定义错误，通过添加特定代码段即可解决。

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

我的是：common.h头文件出错

/usr/local/include/libavutil/common.h

添加如下，即可解决


#ifndef   UINT64_C

#define   UINT64_C(value)__CONCAT(value,ULL)

#endif

/usr/local/include/libavutil/common.h 里面的common.h出错了 主要是c和c++区别 在common.h的最上面添加 #ifndef   UINT64_C #define   UINT64_C(value)__CONCAT(value,ULL) #endif 问题就可以解决 如果ubuntu11.04可以根据h

嗯，用户遇到了编译错误，提示‘av_image_alloc’未声明，建议‘av_max_alloc’。之前已经介绍过这个函数可能的错误原因，但这次的问题明显不同，是编译时找不到函数声明。 首先，我应该想到这可能是因为头文件没有...

原来，为了让pkg-config可以得到这些信息，要求库的提供者，提供一个.pc文件，.pc文件里面存放的是一些头文件及库的地址。这些.pc文件默认放在/usr/share/pkgconfig里面，如果你改变了.pc的存放路径，必须要让计算机知道，所以需要修改 PKG_CONFIG_PATH。ffmpeg 默认是用C文件来编译的，如果某个CPP文件想引用ffmpeg中的某些函数或者头文件，有可能出现。方法：运行live\genWindowsMakefiles.cmd，生成VS能够编译的*.mak文件。

包含libavutil\common.h，由于里面#include ,会出现找不到inttypes.h的问题， 即使把inttypes.h的路径加上去之后，也无法编译通过，反而会出现一大堆问题。 解决办法如下： 删除#include 这句，加上下面一大段 //Howard 2013-03-04 ， 解决包含inttypes.h以后出现的Bug //#include //Howard
