export PATH=/opt/zlg/m1808-sdk-v1.6.0-ga/host/bin:$PATH
export CC=aarch64-linux-gnu-gcc

$ source ~/.bashrc
$ aarch64-linux-gnu-gcc -v

2.2 修改nginx编译配置
nginx本身并不支持交叉编译，因此需要对其进行一定的修改。（具体修改看m1808-nginx-with-rtmp.patch里面的内容)

将m1808-nginx-with-rtmp.patch文件拷贝到解压后的nginx-1.12.2目录，并进入nginx-1.12.2源码目录，将m1808-nginx-with-rtmp.patch补丁打上

$ cd nginx-1.12.2/
$ patch -p1 <m1808-nginx-with-rtmp.patch

file: m1808-nginx-with-rtmp.patch

2.3 新建config.sh脚本，添加configure配置项
$ vim config.sh
./configure \
--crossbuild=Linux::aarch64 \
--with-ld-opt= \
--with-ipv6 \
--prefix=../nginx-install/ \
--conf-path=/etc/nginx/nginx.conf \
--sbin-path=/usr/sbin/nginx \
--pid-path=/var/run/nginx.pid \
--lock-path=/var/run/lock/nginx.lock \
--user=www-data \

--with-debug \
--with-cc-opt='-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -DUSE_UPDATEENGINE=ON -DSUCCESSFUL_BOOT=ON'

2.4 对objs/Makefile的修改
执行./config.sh脚本后生成用于编译的objs/Makefile文件，由于在configure配置项上无法配置pcre的交叉编译环境，因此在执行make编译前，还需要对objs/Makefile做修改。

打开objs/Makefile

1 添加pcre的交叉编译环境，如下：

2 由于编译链接libcrypto.a库时需要加在-ldl -lpthread的前面，否则会报错，因此修改objs/Makefile如下：

3 由于通过objs/Makefile直接编译openssl，在编译过程中会出现交叉编译环境不正确的情况。最终采用以下方式解决openssl交叉编译问题，如下：
在执行make编译前，先进入到…/openssl-1.1.1h/的目录，执行如下Configure配置：

$ ./Configure \
linux-armv4 \
--prefix=/home/yanz/opt/nginx-rtmp-build/openssl-1.1.1h/.openssl \
no-shared no-asm no-ssl2 \
-DOPENSSL_USE_IPV6 \
-DOPENSSL_NO_DYNAMIC_ENGINE

这里暂不对openssl的配置命令做详述，有兴趣可以查阅相关资料。

然后回到nginx-1.12.2源码目录下，修改objs/Makefile，将一下两行配置删除：
