Ubuntu交叉编译Nginx+nginx-mod-rtmp

一、设置交叉编译环境

这里使用的天嵌的交叉编译器，目录在
/opt/EmbedSky/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu

安装依赖环境


apt-get install pkg-config autoconf libtool automake python2.7-dev libpython2.7-dev

nano -w /etc/profile

export PATH=$PATH:/opt/EmbedSky/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu/bin

source /etc/profile

二、下载对应的软件包

mkdir -p /srv/build/nginx
cd /srv/build/nginx
wget https://nginx.org/download/nginx-1.24.0.tar.gz
wget https://github.com/arut/nginx-rtmp-module/archive/refs/heads/master.zip
mv master.zip nginx-rtmp-module.zip
tar xzvf nginx-1.24.0.tar.gz
unzip nginx-rtmp-module.zip
mv nginx-rtmp-module-master nginx-rtmp-module

wget https://sourceforge.net/projects/pcre/files/pcre/8.45/pcre-8.45.zip/download
mv download pcre-8.45.zip
unzip pcre-8.45.zip

wget http://www.zlib.net/current/zlib.tar.gz
tar xzvf zlib.tar.gz

wget https://github.com/openssl/openssl/archive/refs/tags/OpenSSL_1_1_1a.tar.gz
tar xzvf OpenSSL_1_1_1a.tar.gz
mv openssl-OpenSSL_1_1_1a libopenssl-1.1.1a

wget https://github.com/arut/nginx-dav-ext-module/archive/refs/tags/v3.0.0.tar.gz
mv v3.0.0.tar.gz nginx-dav-ext-module.tar.gz
tar xzvf nginx-dav-ext-module.tar.gz

wget https://download.gnome.org/sources/libxml2/2.10/libxml2-2.10.4.tar.xz
tar xvf libxml2-2.10.4.tar.xz
cd libxml2-2.10.4
./configure --host=aarch64-linux-gnu --prefix=/opt/EmbedSky/arm-linux-libxml2 CROSS_COMPILE=aarch64-linux-gnu- CC=aarch64-linux-gnu-gcc --without-python --without-zlib
make
make install

wget https://download.gnome.org/sources/libxslt/1.1/libxslt-1.1.36.tar.xz
tar xvf libxslt-1.1.36.tar.xz
cd libxslt-1.1.36
./configure --host=aarch64-linux-gnu --prefix=/opt/EmbedSky/arm-linux-libxslt CC=aarch64-linux-gnu-gcc --with-libxml-prefix=/opt/EmbedSky/arm-linux-libxml2  --without-python
make
make install

三、交叉编译

删除部分依赖

nano -w nginx-dav-ext-module-3.0.0/config

#ngx_module_libs=LIBXSLT
ngx_module_libs=-lxml2

生成编译指令

#export SYSROOT=/opt/EmbedSky/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu/sysroot

export PATH=$PATH:/opt/EmbedSky/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu/bin
cd nginx-1.24.0
C_INCLUDE_PATH=/opt/EmbedSky/arm-linux-libxml2/include/libxml2:/opt/EmbedSky/arm-linux-libxslt/include
export C_INCLUDE_PATH
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/EmbedSky/arm-linux-libxml2/lib:/opt/EmbedSky/arm-linux-libsxlt/lib
export LD_LIBRARY_PATH

./configure \

    --with-http_addition_module \
    --with-http_auth_request_module \
    --with-http_dav_module \
    --add-module="../nginx-dav-ext-module-3.0.0" \
    --with-http_degradation_module \
    --with-http_flv_module \
    --with-http_gunzip_module \
    --with-http_gzip_static_module \

    --add-module=../nginx-rtmp-module \
    --with-cc=aarch64-linux-gnu-gcc \
    --with-cpp=aarch64-linux-gnu-g++ \
    --with-cc-opt="-I /opt/EmbedSky/arm-linux-libxml2/include/libxml2 -I /opt/EmbedSky/arm-linux-libxslt/include" \
    --with-ld-opt="-L /opt/EmbedSky/arm-linux-libxml2/lib -L /opt/EmbedSky/arm-linux-libsxlt/lib" \
    --with-pcre=../pcre-8.45 \
    --with-openssl=../libopenssl-1.1.1a \
    --with-zlib=../zlib-1.3.1

安装到目录/opt/nginx,然后压缩文件即可

make
export DESTDIR=/opt/nginx
make install

修复错误一

checking for OS
 + Linux 5.4.0-150-generic x86_64
checking for C compiler ... found but is not working

./configure: error: C compiler aarch64-linux-gnu-gcc is not found

nano -w auto/cc/name

 if [ "$NGX_PLATFORM" != win32 ]; then

    ngx_feature="C compiler"
    ngx_feature_name=yes
    ngx_feature_run=no 
    ngx_feature_incs=
    ngx_feature_path=
    ngx_feature_libs=
    ngx_feature_test=
    . auto/feature

#    if [ $ngx_found = no ]; then
#        echo
#        echo $0: error: C compiler $CC is not found
#        echo
#        exit 1
#    fi

fi

修复错误二

checking for int size ..../configure: 1: auto/types/sizeof: objs/autotest: Exec format error
  bytes

./configure: error: can not detect int size

nano -w auto/types/sizeof

if [ -x $NGX_AUTOTEST ]; then
    ngx_size=8              
    echo " $ngx_size bytes"
fi

修复错误三

checking whether we are cross compiling... configure: error: in `/srv/build/nginx/pcre-8.45':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details
objs/Makefile:1798: recipe for target '../pcre-8.45/Makefile' failed

nano -w objs/Makefile   每次

CFLAGS = -DNGX_HAVE_GCC_ATOMIC=1 -pipe  -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Werror -g 

./pcre-8.45/Makefile:  objs/Makefile
        cd ../pcre-8.45 \
        && if [ -f Makefile ]; then $(MAKE) distclean; fi \
        && CC="$(CC)" CFLAGS="-O2 -fomit-frame-pointer -pipe " \
        ./configure --disable-shared --enable-jit  --host=aarch64-linux-gnu

修复错误四

../libopenssl-1.1.1a/.openssl/lib/libssl.a: 无法添加符号: 文件格式错误

nano -w auto/lib/openssl/make   每次

 && ./config --prefix=$ngx_prefix no-shared no-threads no-asm --cross-compile-prefix=/opt/EmbedSky/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu- \\

修复错误五

aarch64-linux-gnu-gcc: error: unrecognized command line option ‘-m64’

nano -w ../libopenssl-1.1.1a/Makefile

CNF_CFLAGS=-m64 -Wa,--noexecstack
CNF_CXXFLAGS=-std=c++11 -m64

这个需要修复了执行

make && make install

错误六

core/ngx_cycle.c:485：对‘ngx_shm_alloc’未定义的引用

nano -w objs/ngx_auto_config.h

第十六行

#ifndef NGX_HAVE_SYSVSHM
#define NGX_HAVE_SYSVSHM 1
#endif

错误七

nginx: [alert] shmget(384) failed (38: Function not implemented)

P.S. 勾選Kernel的System V IPC選項並且重新編譯下載
