Compiling ffmpeg with --prefix option

[Abhijit Das]

Hello Everyone,

I am trying to compile the ffmpeg source code following the guideline
below. I am using ubuntu 11.10
http://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide

This is an excellent guide. But I have a small problem.  I wanted to
install all the binary and libraries in /opt/ffmpeg including libvpx and
libx264.

However when I try to configure ffmpeg it is throwing error:
ERROR: libvpx decoder version must be >=0.9.1

So it seems ./configure could not locate the libraries I compiled before in
/opt/ffmpeg/lib

How do I make ./configure happy? How do I specify the library path to
search for as an option to ./configure?

Thanks -Abhijit Das

LDFLAGS possibly?

Untested example:

sudo apt-get update
sudo apt-get -y install build-essential git yasm
cd
mkdir -p junk/src
git clone git://git.videolan.org/x264
cd x264
./configure --prefix=$HOME/junk --enable-static
make
make install
cd
git clone --depth 1 git://source.ffmpeg.org/ffmpeg
cd ffmpeg
./configure --extra-cflags="-I$HOME/junk/include" \
--extra-ldflags="-L$HOME/junk/lib" --enable-gpl --enable-libx264
make

My test static build script includes...

./configure \
--extra-version=by_Tim \
--enable-static --disable-shared \
--prefix=$SYSROOT/usr/local \
--libdir=$SYSROOT/usr/local/lib64 \
--samples="../fate-suite/" \
--extra-cflags="-static -I$SYSROOT/usr/local/include" \
--extra-ldflags="-static -L$SYSROOT/usr/local/lib64" \
--progs-suffix="_$build_date" \

Having set $SYSROOT to my desired location.
