i found a working solution . but don't understand why it is like this, can
someone explain it?
first i compiled openssl
cd build/openssl*
./config --prefix=/usr/tmp/tmp/ffmpeg-static/target no-shared
make
make install
then librtmp
cd build/rtmp*
# patch rtmpdump makefile to include -ldl
sed
if i don't add --extra-libs=-ldl, it errors out saying ld can not find
ldl
no i don't have a static openssl installed in your system, i think the
installed one is dynamic.
if i don't static compile it , it errors out with error message like ld
can not find -lssl

Does your linking command line which is throughing this error even have
-lrtmp or librtmp.a in it?

first i compiled rtmpdump as follows
git clone git://git.ffmpeg.org/rtmpdump
cd rtmpdump
make SYS=posix SHARED=
make install prefix=/usr/tmp/tmp/ffmpeg-static/target SHARED=
i checked in the target dir , the .a and .pc files are there.
then in ffmpeg folder i run configure as
./configure
if i remove the -static from the configure command line , by using
./configure --enable-librtmp --prefix=/usr/tmp/tmp/ffmpeg-
static/target --extra-cflags=-I/usr/tmp/tmp/ffmpeg-static/target/include
--extra-ldflags=-L/usr/tmp/tmp/ffmpeg-static/target/lib -lm
--extra-version=static --disable-debug
