使用LEAN源码编译固件出现undefined reference to `pthread_once'错误的解决办法

编译过程中出现提示如下后失败：

百度了2天没找到答案，哪位大神能给分析一下如何解决，先谢谢了。

百度 undefined reference to `pthread_once'错误都是说编译时加参数-lpthread，但是不知道从哪个makeconfig文件里加？

解决了，在lede/build_dir/target-arm_xscale_musl_eabi/linux-kirkwood/linux-5.4.83/scripts/Makefile中

把HOSTLDLIBS_extract-cert = -lcrypto后面加上 -pthread
即HOSTLDLIBS_extract-cert = -lcrypto -pthread
OK

，我只想说，我在wsl，下遇到问题，各种问题，原因是文件权限问题，
在deepin遇到问题，是因为把编译文件放到了挂载的U盘里面导致的文件权限问题
在deepin遇上的问题，是因为文件的DL文件不完整
，解决以上问题，轻轻松松出固件
