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：
[linuxidc@linuxidc bin]$ pwd/var/VMdisks/cross/mingw32/bin
[linuxidc@linuxidc bin]$ lslrelease 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
[linuxidc@linuxidc 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：
[linuxidc@linuxidc 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
[linuxidc@linuxidc bin]$ rpm -qa |grep glibcglibc-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/
[linuxidc@linuxidc bin]$ cd /var/VMdisks/glibc-2.14/ [linuxidc@linuxidc glibc-2.14]$ pwd/var/VMdisks/glibc-2.14

c.在glibc源码目录建立构建目录，并cd进入构建目录
[linuxidc@linuxidc glibc-2.14]$ mkdir build [linuxidc@linuxidc glibc-2.14]$ cd buildd.运行configure配置，make && sudo make install
[linuxidc@linuxidc build]$ ../configure --prefix=/opt/glibc-2.14 [linuxidc@linuxidc build]$ make -j4 [linuxidc@linuxidc build]$ sudo make install [sudo] password for ghui:4.临时修改环境变量
[linuxidc@linuxidc bin]$ export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH [linuxidc@linuxidc glibc-2.14]$ cd /var/VMdisks/cross/mingw32/bin/ [linuxidc@linuxidc 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。
