cd glibc-2.31

make -j6
make install
make localedata/install-locales

如出现如下错误可以忽略

LD_SO=ld-linux-x86-64.so.2 CC="gcc -B/usr/bin/" /usr/bin/perl scripts/test-installation.pl /opt/glibc-2.31/build/
/usr/bin/ld: cannot find -lnss_test2
collect2: error: ld returned 1 exit status
Execution of gcc -B/usr/bin/ failed!
The script has found some problems with your installation!
Please read the FAQ and the README file and check the following:
- Did you change the gcc specs file (necessary after upgrading from
  Linux libc5)?
- Are there any symbolic links of the form libXXX.so to old libraries?
  Links like libm.so -> libm.so.5 (where libm.so.5 is an old library) are wrong,
  libm.so should point to the newly installed glibc file - and there should be
  only one such link (check e.g. /lib and /usr/lib)
You should restart this script from your build directory after you've
fixed all problems!
Btw. the script doesn't work if you're installing GNU libc not as your
primary library!
make[1]: *** [Makefile:120: install] Error 1
