[MEncoder-users] Problem with configure script

[Josef Wolf]

Hello,

I am trying to recompile mencoder to adjust MAX_SKEW_DELTA in
stream/tvi_v4l2.c as suggested in

  http://lists.mplayerhq.hu/pipermail/mplayer-users/2010-April/079686.html

but the configure script bails out with

  Checking for Nemesi Streaming Media libraries ... no
  Checking for LIVE555 Streaming Media libraries ... no
  Checking for FFmpeg libavutil ...
  Error: You need static or shared libavutil, MPlayer will not compile without!
  
  Check "configure.log" if you do not understand why it failed.
  make: *** [configure-arch-stamp] Error 1
  jw at ubuntu:~/dvd/mencoder/mplayer-1.0~rc3+svn20090426$

But I _have_ libavutil installed. In configure.log, I find those lines:

  ============ Checking for FFmpeg libavutil ============
  
  #include <libavutil/common.h>
  int main(void) { av_gcd(1,1); return 0; }
  
  cc -W -Wall -O2 -march=i586 -mtune=i586 -pipe -g \
    -I. -I/home/jw/dvd/mencoder/mplayer-1.0~rc3+svn20090426/debian/include
    -Ilibdvdread4 -I/usr/include/freetype2     -lncurses -lfreetype -lz   -lXext \
    -lX11 -lpthread -lXvMC -l  -o /tmp/mplayer.7UrWSB/mplayer-conf--26000 \
                           ^^^^^^
    /tmp/mplayer.7UrWSB/mplayer-conf--26000.c -lavutil
  
  cc: /tmp/mplayer.7UrWSB/mplayer-conf--26000: No such file or directory /tmp/mplayer.7UrWSB/mplayer-conf--26000.c: In function 'main': /tmp/mplayer.7UrWSB/mplayer-conf--26000.c:2: warning: implicit declaration of function 'av_gcd'

Notice the missing library name between the -l and the -o switch when the
compiler is called. Is this a bug in the configure script? How can I work
around this?

BTW: Will MAX_SKEW_DELTA be changed in some future release of mencoder?
