【linux】提示"libc.so.6: version `GLIBC_2.14' not found",系统的glibc版本太低
0.以下在系统CentOS 6.3 x86_64上操作
1.试图运行程序，提示"libc.so.6: version `GLIBC_2.14' not found",原因是系统的glibc版本太低，软件编译时使用了较高版本的glibc引起的：
- [ghui@StuOS bin]$ pwd
- /var/VMdisks/cross/mingw32/bin
- [ghui@StuOS bin]$ ls
- lrelease QtCore4.dll QtNetwork4.dll QtSql4.dll QtXml4.dll
- moc QtDeclarative4.dll QtOpenGL4.dll QtSvg4.dll rcc
- phonon4.dll QtGui4.dll QtScript4.dll QtTest4.dll uic
- qmake QtMultimedia4.dll QtScriptTools4.dll QtWebKit4.dll
- [ghui@StuOS bin]$ ./qmake
- ./qmake: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by ./qmake)
2.查看系统glibc支持的版本：
- [ghui@StuOS bin]$ strings /lib64/libc.so.6 |grep GLIBC_
- GLIBC_2.2.5
- GLIBC_2.2.6
- GLIBC_2.3
- GLIBC_2.3.2
- GLIBC_2.3.3
- GLIBC_2.3.4
- GLIBC_2.4
- GLIBC_2.5
- GLIBC_2.6
- GLIBC_2.7
- GLIBC_2.8
- GLIBC_2.9
- GLIBC_2.10
- GLIBC_2.11
- GLIBC_2.12
- GLIBC_PRIVATE
- [ghui@StuOS bin]$ rpm -qa |grep glibc
- glibc-static-2.12-1.80.el6_3.6.x86_64
- glibc-headers-2.12-1.80.el6_3.6.x86_64
- glibc-common-2.12-1.80.el6_3.6.x86_64
- glibc-devel-2.12-1.80.el6_3.6.x86_64
- glibc-static-2.12-1.80.el6_3.6.i686
- glibc-devel-2.12-1.80.el6_3.6.i686
- glibc-2.12-1.80.el6_3.6.i686
- glibc-2.12-1.80.el6_3.6.x86_64
3.可以看到最高只支持2.12版本，所以考虑编译解决这个问题：
a. 到http://www.gnu.org/software/libc/下载最新版本，我这里下载了glibc-2.14.tar.xz 这个版本，解压到任意目录准备编译
b.这里解压到/var/VMdisks/glibc-2.14/
- [ghui@StuOS bin]$ cd /var/VMdisks/glibc-2.14/
- [ghui@StuOS glibc-2.14]$ pwd
- /var/VMdisks/glibc-2.14
- [ghui@StuOS glibc-2.14]$ ls

c.在glibc源码目录建立构建目录，并cd进入构建目录
- [ghui@StuOS glibc-2.14]$ mkdir build
- [ghui@StuOS glibc-2.14]$ cd build
d.运行configure配置，make && sudo make install
- [ghui@StuOS build]$ ../configure --prefix=/opt/glibc-2.14
- [ghui@StuOS build]$ make -j4
- [ghui@StuOS build]$ sudo make install
- [sudo] password for ghui:
4.临时修改环境变量
- [ghui@StuOS bin]$ export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH
- [ghui@StuOS glibc-2.14]$ cd /var/VMdisks/cross/mingw32/bin/
- [ghui@StuOS bin]$ ./qmake
- Usage: ./qmake [mode] [options] [files]
- QMake has two modes, one mode for generating project files based on
- some heuristics, and the other for generating makefiles. Normally you
- shouldn't need to specify a mode, as makefile generation is the default
- mode for qmake, but you may use this to test qmake on an existing project
- ...
此时运行正常，问题解决。
