第一篇博客，简单记录最近关于rtmp的移植于使用，参考了雷大神的文章 RTMPdump 使用说明     在此说明，感谢分享

zlib

git clone https://github.com/madler/zlib.git -b v1.2.11 --depth=1
CHOST=arm-himix200-linux ./configure --static  --prefix=${PWD}/../../

make

openssl

wget https://www.openssl.org/source/openssl-1.0.2u.tar.gz
tar -zxf openssl-1.0.2u.tar.gz

cd ./openssl-1.0.2u/
./Configure linux-armv4 no-asm no-shared --prefix=${PWD}/../../ --cross-compile-prefix=arm-himix200-linux-
``

librtmp

git clone git://git.ffmpeg.org/rtmpdump --depth=1

vi rtmpdump/librtmp/Makefile

———移植———————————————————————————————————————————————————————————

rtmpdump 官网（http://rtmpdump.mplayerhq.hu/）上的打包版本都比较低，
源码下载
git clone git://git.ffmpeg.org/rtmpdump

make SYS=posix CROSS_COMPILE=arm-hisiv300-linux- INC=-I/usr/include

rtmpdump 依赖库有 zlib 和  openssl（或者是POLARSSL  GNUTLS，这三个都是ssl协议库目前流行的就是openssl了 ），

arm-himix200-linux-gcc -Wall -I../../../include -DRTMPDUMP_VERSION=\"v2.4\" -DUSE_OPENSSL -O2 -fPIC -c -o rtmp.o rtmp.c
In file included from handshake.h:86:0,

             from rtmp.c:152:

dh.h: In function 'DHInit':
dh.h:256:12: error: dereferencing pointer to incomplete type 'DH {aka struct dh_st}'
MP_new(dh->g);

解决方法： 仔细核对编译路径，一定是路径出问题了。

XCFLAGS=-I../include #增加编译选项，包括依赖库的路径
XLDFLAGS=-L../lib #增加交叉编译工具链选项

2、zlib的移植

下载连接 http://www.zlib.net/   
http://zlib.net/zlib-1.2.8.tar.gz

git clone https://github.com/madler/zlib.git -b v1.2.11 --depth=1

# export PATH=$(pwd)/raspberrypi/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin:$PATH

CHOST=arm-himix200-linux ./configure --static  --prefix=../libz # 默认：--prefix=/usr/local/

make

git clone https://github.com/madler/zlib.git -b v1.2.11 --depth=1

Cross compile zlib with shared & static lib
Setup config >> libz.a libz.so

$ CHOST=arm-hisiv400-linux-gcc ./configure –-prefix=$HOME/openssh/package/zlib

  1. Cross compile zlib with static lib
    Setup config >> libz.a
    $ ./configure --static –prefix=$HOME/openssh/package/zlib/
    Edit Makefile

$ vi Makefile

  1. Find and replace the following:

    CC=arm-hisiv400-linux-gcc
    LDSHARED=arm-hisiv400-linux-gcc
    CPP=arm-hisiv400-linux-gcc -E
    AR=arm-hisiv400-linux-ar
    RANLIB=arm-hisiv400-linux-ranlib

  2. Complie and install zlib

$ make
$ make install

3、rtmpdump 移植

git clone git://git.ffmpeg.org/rtmpdump --depth=1

rtmp源码包一共有两个Makefile，分别修改他们 
make CROSS_COMPILE=arm-none-linux- INC=-I/my/cross/includes

1.修改编译 librtmp

$vi librtmp/Makefile
prefix=${PWD}/..
XCFLAGS=-I/home/ubuntu/cpp/3rdpart/libssl/include -I/home/ubuntu/cpp/3rdpart/libz/include  #增加编译选项，包括依赖库的路径
XLDFLAGS=-L/home/ubuntu/cpp/3rdpart/libssl/lib -L/home/ubuntu/cpp/3rdpart/libz/lib #增加交叉编译工具链选项
XCFLAGS=-I../../../include
XLDFLAGS=-L../../../lib
CROSS_COMPILE=arm-himix200-linux-

修改编译 rtmpdump

修改根目录下的Makefile 
$vi Makefile

prefix=${PWD}/output
XCFLAGS=-I./include
XLDFLAGS=-Llib -L/home/ubuntu/cpp/3rdpart/libssl/lib -L/home/ubuntu/cpp/3rdpart/libz/lib 
CROSS_COMPILE=arm-himix200-linux-

本地编译可能需要dl库，增加链接库选项{
#LIB_OPENSSL=-lssl -lcrypto $(LIBZ)
LIB_OPENSSL=-lssl -lcrypto $(LIBZ) -ldl
}

修改

修改完后直接 make   ； make install
