[Ffmpeg-devel] compile vorbis error in ffmpeg using MinGW

[FCG WANG Baohua]

Dear All:
 I use the ffmpeg-0.4.9-pre1 version, add "--enable-vorbis" option to compile the ffmpeg.
I had download the libvorbis-1.1.2 and libogg-1.1.3 and build , install successfully.
But when I compile the ffmpeg. it shows the following error:

It seem that it cannot find the libogg. But I had put it in /MinGW/lib and  /MinGW/MSYS/local/lib, How could I do? thanks !
