안녕하세요 고수님들

ffmpeg 라이브러리는 포팅 하였는데 doc/examples/decoding_encoding.c 파일을 컴파일이 안됩니다.

아래와 같이 ffmpeg 라이브러리를 포팅 하였습니다.

./configure --target-os=linux --arch=armv7 --enable-cross-compile --cc=/usr/local/arm/arm-2009q3/bin/arm-none-linux-gnueabi-gcc --cross-prefix=/usr/local/arm/arm-2009q3/bin/arm-none-linux-gnueabi- --enable-shared --enable-avresample --enable-libvorbis --prefix=/mnt/mtd6/ffmpeg

make

make install

doc/examples들을 컴파일 하고 싶은데 되지 않습니다. 알려주세요.....

 make시 에러
