hi, dear developers, current glibc version what we used is 2.28 and it was launched at year 2018, it's too old for our system and there are little bugs which are not fixed. and lately gcc version was updated to 9.3, the glibc upstream community has already do a lot of works to adapt this change in the latest version. so in the next week, we will update glibc to the latest version 2.31. notice that this change will cause other package's build result which depend on the glibc. so I need all of your help to resolve this situlation by update your own package or use other ways. thx.
