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]$ lslreleaseQtCore4.dllQtNetwork4.dllQtSql4.dllQtXml4.dllmocQtDeclarative4.dll QtOpenGL4.dllQtSvg4.dllrccphonon4.dll QtGui4.dllQtScript4.dllQtTest4.dll uicqmakeQtMultimedia4.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_2.2.5GLIBC_2.2.6GLIBC_2.3GLIBC_2.3.2GLIBC_2.3.3GLIBC_2.3.4GLIBC_2.4GLIBC_2.5GLIBC_2.6GLIBC_2.7GLIBC_2.8GLIBC_2.9GLIBC_2.10GLIBC_2.11GLIBC_2.12GLIBC_PRIVATE[ghui@StuOS bin]$ rpm -qa |grep glibcglibc-static-2.12-1.80.el6_3.6.x86_64glibc-headers-2.12-1.80.el6_3.6.x86_64glibc-common-2.12-1.80.el6_3.6.x86_64glibc-devel-2.12-1.80.el6_3.6.x86_64glibc-static-2.12-1.80.el6_3.6.i686glibc-devel-2.12-1.80.el6_3.6.i686glibc-2.12-1.80.el6_3.6.i686glibc-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]$ lsabilistconfig.h.inintlREADME.libmabi-tagsconfig.logioresolvaclocal.m4config.make.inlibc-abisresourceaoutconfigurelibidnrtargpconfigure.inlibioRulesassertconformLICENSESscriptsautom4te.cacheCONFORMANCElocalesetjmpbitsCOPYINGlocaledatashadowBUGSCOPYING.LIBloginshlib-versionsbuildcppflags-iterator.mk machsignalCANCEL-FCT-WAIVE cryptMakeconfigsocketCANCEL-FILE-WAIVE csuMakefilesoft-fpcatgetsctypeMakefile.in stdio-commonChangeLogdebugMakerulesstdlibChangeLog.1direntmallocstreamsChangeLog.10dlfcnmanualstringChangeLog.11elfmathsunrpcChangeLog.12extra-lib.mkmiscsysdepsChangeLog.13extra-modules.mkNAMESPACEsysvipcChangeLog.14FAQNEWStermiosChangeLog.15FAQ.innistest-skeleton.cChangeLog.16gmonNOTEStimeChangeLog.17gnulibnptltimezoneChangeLog.2grpnptl_dbtls.make.cChangeLog.3gshadownscdversion.hChangeLog.4hesiodnssVersions.defChangeLog.5hurdo-iterator.mk wcsmbsChangeLog.6iconvpowctypeChangeLog.7iconvdataposixWUR-REPORTChangeLog.8includePROJECTSChangeLog.9inetpwdconfINSTALLREADME 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 onsome heuristics, and the other for generating makefiles. Normally youshouldn’t need to specify a mode, as makefile generation is the defaultmode for qmake, but you may use this to test qmake on an existing project…
此时运行正常，问题解决。
