[FFmpeg-user] How to build ffmpeg statically with librtmp support

[Han Jiang]

my lasted attemp in the build script is

# comment out the "require_pkg_config librtmp ..." line
# this line assumes you have installed librtmp to your /usr/lib64
# but here i want a "static" build
sed -i.bak '/enabled librtmp/s/^/# /' configure
CFLAGS="-I$TARGET_DIR/include" LDFLAGS="-L$TARGET_DIR/lib -lm" ./configure
--prefix=${OUTPUT_DIR:-$TARGET_DIR} --extra-cflags="-I$TARGET_DIR/include
-static" --extra-ldflags="-L$TARGET_DIR/lib -lm -static"
--extra-version=static --disable-debug --disable-shared --enable-static
--extra-cflags=--static --pkg-config-flags="-static" --disable-ffplay
--disable-ffserver --disable-doc --enable-gpl --enable-pthreads
--enable-postproc --enable-gray --enable-runtime-cpudetect --enable-libfaac
--enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis
--enable-libx264 --enable-libxvid --enable-bzlib --enable-zlib
--enable-nonfree --enable-version3 --enable-libvpx --disable-devices
--enable-librtmp

and the error is
