[MPlayer-dev-eng] How to test main function in subreader.c?

[Sunsik Park]

Thank you,
I show you that I did, step by step.

1.configure

./configure --prefix=/home/keti/mplayer/ --disable-ftp --disable-tv
> --disable-tv-teletext --disable-tv-v4l2 \
> --disable-tv-v4l1 --disable-dvdread --disable-network --disable-dvdnav
> --disable-dvdread-internal --disable-qtx \
> --disable-xanim --disable-win32dll --disable-faad-external
> --disable-faad-internal --disable-theora --disable-pnm \
> --disable-png --disable-fbdev --disable-tga --disable-md5sum
> --disable-tremor-internal --disable-mp3lib \
> --disable-real --disable-libmpeg2 --disable-iconv

2. I edited subreader.c

  -#define DUMPSUBS

#include "subreader.h"
> #include "stream/stream.h"
>
> /* by LukePark*/
> #define DUMPSUBS
>
> #ifdef HAVE_ENCA
> #include <enca.h>
>

 -  main in subreader.c

#ifdef DUMPSUBS
> int main(int argc, char **argv) {  // for testing
>     sub_data *subd;
>
>     if(argc<2){
>         printf("\nUsage: subreader filename.sub\n\n");
>         exit(1);
>     }
> /* by LukePark */
> //    sub_cp = argv[2];
> //    subd = sub_read_file(argv[1]);
>
      subd = sub_read_file(argv[1],0); /* subreader.c:2364: error: too few
> arguments to function 'sub_read_file'*/
>
>     if(!subd){
>         printf("Couldn't load file.\n");
>         exit(1);
>     }
>
>     list_sub_file(subd);
>
>     return 0;
> }
> #endif

3. make

 -  I edited libvo/sub.c. because  "sub_utf8"  defined  in sub.h as "extern
int sub_utf8"

4. make

5.make

subreader.o: In function `main':
> subreader.c:(.text+0x49b9): multiple definition of `main'
> mencoder.o:mencoder.c:(.text+0x3e1): first defined here

  - I del main function in mencoder.c ( as comment)

 6. compiling is successful
 7. execution

I can't confirm any result of  "list_sub_file" function. I know , becauset I
deleteed main function  in mplayer.c and mencoder.c

How can I solve this problem ?
