make: *** [Makefile:383：qutfcodec.o] 错误 1
错误分析：该错误发生在编译器处理avx512vp2intersectintrin.h头文件时，表明当前编译环境未显式启用AVX-512 VP2INTERSECT指令集选项或该机器CPU不支持该指令集。
解决过程：首先验证该机器否支持该指令集，验证指令如下：
lscpu | grep avx512
若有输出，则当前CPU支持 avx512相关指令集，此时说明编译构建脚本程序或编译构建指令未显式的启用avx512相关指令集，相关编译器的启用avx512指令集的方法如下（构建脚本程序的修改不做细节阐述，如有需要自行百度）：
（1）GCC/Clang编译器需添加-mavx512vp2intersect选项
（2）若使用Intel编译器，需添加-xCOMMON-AVX512或-xCORE-AVX512
若有输出，则当前CPU不支持 avx512相关指令集，则此时的解决方法主要有两种：
（1）下载未使用avx512指令集的低版本的待编译程序（此处为低版本的qt）【不推荐使用，因为当前时间为2025年，而avx512指令集在2011年intel酷睿2代芯片上就已经推出，若当前硬件不支持，则说明该机器也该报废了，若更改低版本的待编译程序，编译后的古老程序也不一定符合前的应用要求】；
（2）更换新机器搭建环境重新编译【推荐使用】。其中，若使用的机器为VM创建的虚拟机而非实体机，则可以更改虚拟机配置实现虚拟机CPU avx512指令集的支持，操作流程如下：①关闭虚拟机 ②编辑虚拟机设置 ③进入CPU选项 ④将CPU/MMU虚拟化修改为"硬件CPU和MMU模式" ⑤确保勾选"虚拟化Intel VT-x/EPT或AMD-V/RVI"选项。然后重启虚拟机重新编译即可。
