    ’https://github.com/jrottenberg/ffmpeg/blob/master/docker-images/3.4/Dockerfile’,
    and I changed the docker file to a shell file. Download all source files,
    compile all dependency source and ffmpeg 3.4.1 source.
    The following is my changed shell script.

    #

    Now I write a simple code, save as a 0_hello_world.c file.

    #

    #include "libavcodec/avcodec.h"
    
#include "libavformat/avformat.h"
    
#include 
    
#include 
    
#include 
    
#include 
    
#include 
    
#include 
    
#include 
    
#include "libavutil/error.h"
    
int main(int argc, const char *argv[])
    
{
    
av_register_all();
    
int response = 0;
    
char *pchar;
    
// pchar = av_err2str(response);
    
return 0;
    
}

    #

    Use the follow command for make, it’s OK.

    #

    gcc -g -Wall -o build/hello_world -lz 0_hello_world.c 
    
-lavformat -lavcodec -lswscale 
    
-I/opt/ffmpeg/include -L/opt/ffmpeg/lib

    #

    But when I use the "av_err2str" function(uncomment this line) :
    ’pchar = av_err2str(response) ;’
    compile show the following error :

    #

    gcc -g -Wall -o build/hello_world -lz 0_hello_world.c 
    
-lavformat -lavcodec -lswscale 
    
-I/opt/ffmpeg/include -L/opt/ffmpeg/lib
    
0_hello_world.c: In function ‘main’:
    
0_hello_world.c:16:9: warning: variable ‘pchar’ set but not used [-Wunused-but-set-variable]
    
char *pchar;
    
^
    
/usr/bin/ld: /tmp/ccgJJ9CV.o: undefined reference to symbol 'av_strerror@@LIBAVUTIL_55'
    
/opt/ffmpeg/lib/libavutil.so.55: error adding symbols: DSO missing from command line
    
collect2: error: ld returned 1 exit status
    
Makefile:10: recipe for target 'hello_world' failed
    
make: *** [hello_world] Error 1

    #

    As I know "av_register_all" use the "libavformat/avformat.h" header ; "av_err2str" use the "libavutil/error.h" header.
    Both the two headers I have included, why "av_err2str" is not OK ?
    I guess this is my environment not OK. How can I find the error ?
    I have checked my LD_LIBRARY_PATH, it is OK.
