海思3531D移植srs-2.0.269 st库引发段错误

一、环境

1.交叉编译工具链:arm-hisiv600-linux-gcc，版本4.9.4，glibc-2.2.0
2.srs-2.0.269下载地址:https://github.com/ossrs/srs.git
3.st-1.9修正版本下载地址:https://github.com/ossrs/state-threads.git
4.官方相关issue:https://github.com/ossrs/srs/issues/1282

二、引发的主要报错

可以初步定为为st-1.9与glibc兼容的问题

三、步骤

1.安装交叉编译工具链(略)
2.下载srs-2.0.269

git clone -b 2.0release https://github.com/ossrs/srs.git
cd srs/trunk

3.修改srs相关setup_variables.sh

vim auto/setup_variables.sh 

if [ $SRS_ARM_UBUNTU12 = YES ]; then
__SrsArmCC=“arm-linux-gnueabi-gcc”;
__SrsArmGCC=“arm-linux-gnueabi-gcc”;
__SrsArmCXX=“arm-linux-gnueabi-g++”;
__SrsArmAR=“arm-linux-gnueabi-ar”;
__SrsArmLD=“arm-linux-gnueabi-ld”;
__SrsArmRANDLIB=“arm-linux-gnueabi-ranlib”;
fi
更改为海思3531D工具链
if [ $SRS_ARM_UBUNTU12 = YES ]; then
__SrsArmCC=“arm-hisiv600-linux-gcc”;
__SrsArmGCC=“arm-hisiv600-linux-gcc”;
__SrsArmCXX=“arm-hisiv600-linux-g++”;
__SrsArmAR=“arm-hisiv600-linux-ar”;
__SrsArmLD=“arm-hisiv600-linux-ld”;
__SrsArmRANDLIB=“arm-hisiv600-linux-ranlib”;
fi

4.下载编译st-1.9修正版本，并进行相关操作

git clone -b srs https://github.com/ossrs/state-threads.git
//变更文件夹名
mv state-threads st-1.9
//压缩文件夹为zip
zip -r st-1.9.zip st-1.9
//将zip文件替换srs原始的文件
mv st-1.9.zip srs/trunk/3rdparty
//打开 depends.sh  422行
vim srs/trunk/auto/depends.sh 

echo “build st-1.9t for arm”;
(
rm -rf ${SRS_OBJS}/st-1.9 && cd ${SRS_OBJS} &&
unzip -q …/3rdparty/st-1.9.zip && cd st-1.9 && chmod +w * &&
patch -p0 < …/…/3rdparty/patches/1.st.arm.patch &&
patch -p0 < …/…/3rdparty/patches/3.st.osx.kqueue.patch &&
patch -p0 < …/…/3rdparty/patches/4.st.disable.examples.patch &&
patch -p0 < …/…/3rdparty/patches/6.st.osx10.14.build.patch &&
make ${}_S{T}_{M}AKECC=${SrsArmCC} AR=$SrsArmARLD=${SrsArmLD} RANDLIB=$SrsArmRANDLIBEXTR{A}_{C}FLAGS="${_ST_EXTRA_CFLAGS}" &&
cd … && rm -rf st && ln -sf st-1.9/obj st &&
cd … && touch ${SRS_OBJS}/_flag.st.cross.build.tmp
)
将这段替换为,主要是删除patch操作,因为修正版本不需要再patch
echo “build st-1.9t for arm”;
(
rm -rf ${SRS_OBJS}/st-1.9 && cd ${SRS_OBJS} &&
unzip -q …/3rdparty/st-1.9.zip && cd st-1.9 && chmod +w * &&
make ${}_S{T}_{M}AKECC=${SrsArmCC} AR=$SrsArmARLD=${SrsArmLD} RANDLIB=$SrsArmRANDLIBEXTR{A}_{C}FLAGS="${_ST_EXTRA_CFLAGS}" &&
cd … && rm -rf st && ln -sf st-1.9/obj st &&
cd … && touch ${SRS_OBJS}/_flag.st.cross.build.tmp
)

5.配置运行编译脚本

PKG_CONFIG_PATH=/交叉编译库依赖路径/pkgconfig \
CC=arm-hisiv600-linux-gcc \ 
CFLAGS="${CFLAGS} -mcpu=cortex-a9 -mfloat-abi=softfp -mfpu=neon-vfpv4 -mno-unaligned-access -fno-aggressive-loop-optimizations" \ 
CXX=arm-hisiv600-linux-g++ \
CXXFLAGS="${CXXFLAGS} -mcpu=cortex-a9 -mfloat-abi=softfp -mfpu=neon-vfpv4 -mno-unaligned-access -fno-aggressive-loop-optimizations"\
./configure \
 --with-arm-ubuntu12 \
 --prefix=/目标路径 \
 --with-http-api \
 --with-http-callback \
 --with-http-server \
 --with-hls 

执行后会开始编译相关depends，成功后如下所示

5.修改srs_librtmp、objst相关

vim srs/trunk/research/librtmp/Makefile

将第1行 GCC = gcc
改为 GCC = arm-hisiv600-linux-gcc
将第62行改为 ifeq ($(GCC), arm-hisiv600-linux-gcc)

vim srs/trunk/objs/Makefile

GCC = gcc
CXX = g++
AR = ar
LINK = g++
改为
GCC = arm-hisiv600-linux-gcc
CXX = arm-hisiv600-linux-g++
AR = arm-hisiv600-linux-ar
LINK = arm-hisiv600-linux-g++

5.执行make && make install

make && make install	

6.将生成的conf etc objs 拷贝到开发板上运行

./objs/srs -c conf/srs.conf

至此所有报错消失

四、测试
