imx6移植librtmp

一.openssl交叉编译

1.下载

https://www.openssl.org/source/

版本不要太高，刚开始版本高了，有些函数取消了，链接不上

使用1.0.1f即可

2.编译成共享库

./config no-asm shared --prefix=/usr/local/arm/openssl

3.修改Makefile

CROSS_COMPILE=arm-none-linux-gnueabi-

4.make

make install

 

二.zlib交叉编译

1.下载

http://www.zlib.net/zlib-1.2.10.tar.gz

2../configure --prefix=/usr/local/arm/zlib

3.修改Makefile

gcc、ar的地方换成交叉编译器的

 

三.rtmpdump 交叉编译

1.下载

git clone git://git.ffmpeg.org/rtmpdump

2.编译

直接修改makefile，需要修改两个makefile

prefix=/usr/local/arm/librtmp

CROSS_COMPILE=arm-none-linux-gnueabi-

XLDFLAGS=-L/usr/local/arm/openssl/lib -L/usr/local/arm/zlib/lib

XCFLAGS=-I/usr/local/arm/openssl/include -I/usr/local/arm/zlib/include

注意:inlude里不要有文件夹，头文件直接放在include下

3.make

cannot find -lz可能会出现这种错误，产生这种错误是在编译客户程序才出现，此时librtmp库已经生成，直接可以使用.so库
