  Linux upgrade Glibc
     
  Add Date : 2018-11-21      
         
         
         
  I. Introduction

glibc is released gnu libc library, the c runtime. glibc linux system is the bottom of the api, almost any other run-time library will depend on glibc. glibc addition to the systems and services package provided by linux operating system, which itself provides the functions necessary to implement many other services.

This article describes Glibc upgrade

Second, upgrade

Proceed as follows:


wget http://ftp.gnu.org/gnu/glibc/glibc-2.15.tar.gz

wget http://ftp.gnu.org/gnu/glibc/glibc-ports-2.15.tar.gz

tar -xvf glibc-2.15.tar.gz

tar -xvf glibc-ports-2.15.tar.gz

mv glibc-ports-2.15 glibc-2.15 / ports

mkdir glibc-build-2.15

cd glibc-build-2.15

../glibc-2.15/configure --prefix = / usr --disable-profile --enable-add-ons --with-headers = / usr / include --with-binutils = / usr / bin

make & make install

make after the success, build directory compile a new libc.so.6 (/glibc-build-2.15/libc.so.6, we will find that this is actually a soft link, real lib file libc .so

cd glibc-build-2.15
ll libc.so.6

Check the library file, you can see the old library is still 2.12, more than the 2.15 version of the library file, soft links and file all point to the version 2.15

ll / lib64 / libc *

In this case, view the version of glibc support
