编译QT4.4.3的时候，出现如下问题：
Bootstrap QBuild: .. FAILIn file included from ../../../qt-extended-4.4.3/qbuild/src/main.cpp:37:../../../qt-extended-4.4.3/qbuild/src/options.h: In constructor 'Options::Options()':../../../qt-extended-4.4.3/qbuild/src/options.h:52: error: call of overloaded 'QString(int)' is ambiguous/usr/include/qt4/QtCore/qstring.h:428: note: candidates are: QString:String(const QByteArray&)/usr/include/qt4/QtCore/qstring.h:426: note: QString:String(const char*)/usr/include/qt4/QtCore/qstring.h:727: note: QString:String(const QString&)/usr/include/qt4/QtCore/qstring.h:106: note: QString:String(QChar)/usr/include/qt4/QtCore/qstring.h:105: note: QString:String(const QChar*)../../../qt-extended-4.4.3/qbuild/src/main.cpp: In function 'void createProject()':../../../qt-extended-4.4.3/qbuild/src/main.cpp:49: warning: ignoring return value of 'int chdir(const char*)', declared with attribute warn_unused_resultmake[1]: *** [main.o] Error 1make exited with value 2 at /QT4/qt-extended-4.4.3/src/build/bin/configure line 2355make: *** [src/build/mkconf/configure] Error 1./build: line 53: bin/qbuild: No such file or directory./build: line 54: bin/qbuild: No such file or directory
后来问题解决：
1、我之前安装了QT Creator，首先卸载QT Creator
2、使用sudo apt-get autoremove命令删除没有卸载干净的库文件
2、修改配置
重新编译就可以了。
