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:111: install] Error 1 make[1]: Leaving directory '/opt/tmp/glibc-2.30' make: *** [Makefile:12: install] Error 2 # 此编译错误可以无视 root@xxx-xxxx /opt/tmp/glibc-2.30/build # ls -l /lib64/libc.so.6 # 检验是否成功 lrwxrwxrwx 1 root root 12 Sep 18 15:14 /lib64/libc.so.6 -> libc-2.30.so # 表示安装成功 root@xxx-xxxx ~ #
