一、错误现象

我在虚拟机下使用 LVGL 仿真器，编译仿真器源代码时发生报错

编译无法进行

二、错误分析

根据提示分析错误，其中 cc： error 提示报错，翻到 Makefile 一看属于 gcc 编译器

unrecognized command line option ‘-Wshift-negative-value’ 提示无法识别指令，所以分析应该是 GCC 版本的原因，可能我的版本不支持这个指令，解决的方式就是换版本，或者删掉这个指令看能不能正常运行

三、错误解决

这里我先试试删除指令再编译，先用 grep 找到指令在文件的哪一行

grep -n "\-Wshift\-negative\-value" Makefile

编辑文件，删除对应指令

vim make file

保存后程序编译

编译成功，执行 demo，可以正常执行：
