【详述】3.5.3 no-axv2版本的be编译后还是报Illegal instruction
【背景】rm -rf /var/local/thirdparty/installed
cd /root/starrocks/thirdparty
export THIRD PARTY BUILD WITH AVX2=OFF
bash build-thirdparty.sh
In-s /root/starrocks/thirdparty/installed /var/local/thirdparty/installed
cd /root/starrocks
bash build.sh --be --without-avx2
【是否存算分离】
【StarRocks版本】3.5.2
【机器信息】32g,centos7.9,不支持axv2的虚拟机，使用docker编译

能弄一个coredump出来看一下crash的栈吗? 需要看一下是在哪条指令出问题的.

感谢解答,不知道这里怎么获取coredump，是启动be，没有日志，只有Illegal instruction，没有进程
ulimit -c unlimited
允许生成core
cat /proc/sys/kernel/core_pattern
看看core生成的位置, 如果不确定, 可以
echo 'core.%p' > /proc/sys/kernel/core_pattern
将coredump生成文件的位置改到当前路径下.
