讲解在Linux下配置QT 学习之路是本文要介绍的内容，介绍了各种工具包等一些内容。先来看内容。

本文介绍的是讲解在Linux下配置QT 学习之路，我们首先来看内容。在CentOS下配置QT：通过yum search QT，得知源上可以安装的QT软件列表如下(有很多QT组件可以选择安装)：

qt.i386 : Qt GUI 工具包的共享库。

qt-MySQL.i386 : 用于 Qt 的 SQL 类别的 MySQL 驱动程序。

qt-ODBC.i386 : 用于 Qt 的 SQL 类别的 ODBC 驱动程序。

qt-PostgreSQL.i386 : 用于 Qt 的 SQL 类别的 PostgreSQL 驱动程序。

qt-config.i386 : 为使用 Qt 的程序提供的图形化配置工具。

qt-designer.i386 : Qt GUI 工具包的界面设计程序 (IDE)

  1. qt-devel.i386:DevelopmentfilesfortheQtGUItoolkit. 
  2. qt-devel-docs.i386:DocumentationfortheQtGUItoolkit. 
  3. wpa_supplicant-gui.i386:GraphicalUserInterfaceforwpa_supplicant

PyQt.i386 : Qt 的 Python 绑定

PyQt-devel.i386 : 要建构基于 Qt 的其它绑定所需的文件

PyQt-examples.i386 : PyQt 的样例

  1. avahi-qt3.i386:Qt3librariesforavahi//avahi是什么东西? 
  3. avahi-qt3-devel.i386:LibrariesandheaderfilesforavahiQt3development 
  4. pinentry-qt.i386:Passphrase/PINentrydialogbasedonQt 
  5. qt4.i386:ThesharedlibraryfortheQtGUItoolkit 
  6. qt4-devel.i386:DevelopmentfilesfortheQtGUItoolkit 
  7. qt4-doc.i386:APIdocumentation,demosandexampleprogramsforqt4 
  8. qt4-mysql.i386:MySQLdriversforQt'sSQLclasses 
  9. qt4-odbc.i386:ODBCdriversforQt'sSQLclasses 
  10. qt4-postgresql.i386:PostgreSQLdriversforQt'sSQLclasses 
  11. qt4-sqlite.i386:SQLitedriversforQt'sSQLclasses 
  12. qtnx.i386:QT4basedFreeNXClient

scim-qtimm.i386 : Qt 的 SCIM 输入法模块 // 这个是SCIM模块，用Qt实现的吧?

  1. scribus.i386:DeskTopPublishingapplicationwritteninQt 
  2. sip.i386:SIP-Python/C++绑定生成器.

通过rpm命令查询已经安装的Qt软件：

  1. [root@Tomato~]#rpm-qa|grepqt 
  2. qt-3.3.6-23.el5 
  3. scim-qtimm-0.9.4-5 
  4. avahi-qt3-0.6.16-6.el5//Qt3和Qt4可以同时共存吗?

Linux上编译居然因为环境变量，而报错：

  1. QMAKESPEChasnotbeenset,soconfigurationcannotbededuced. 
  2. Errorprocessingprojectfile:/root/qt/qt.pro

在脚本里加入该环境变量，这个错误已经消失：

  1. [root@localhostqt]#ls 
  2. hello.cpp 
  3. [root@localhostqt]#qmake-project 
  4. [root@localhostqt]#ls 
  5. hello.cppqt.pro 
  6. [root@localhostqt]#qmake 
  7. [root@localhostqt]#ls 
  8. hello.cppMakefileqt.pro

Make报如下错误：

  1. [root@localhostqt]#make 
  2. g++-c-pipe-O2-Wall-W-D_REENTRANT-DQT_NO_DEBUG-DQT_GUI_LIB-DQT_CORE_LIB
  3. -I/work/program/dsk/qt-everywhere-opensource-src-4.6.1/mkspecs/linux-g++-I.

  5. -I/work/program/qtdevelop/include-I.-I.-ohello.ohello.cpp 
  6. hello.cpp:1:24:错误：QApplication：没有那个文件或目录 
  7. hello.cpp:2:18:错误：QLabel：没有那个文件或目录

  9. hello.cpp:6:错误：‘QApplication’在此作用域中尚未声明

  11. hello.cpp:7:错误：‘QLabel’在此作用域中尚未声明 
  12. hello.cpp:7:错误：‘label’在此作用域中尚未声明 
  13. hello.cpp:7:错误：expectedtype-specifierbefore‘QLabel’ 
  14. hello.cpp:7:错误：expected`;'before‘QLabel’ 
  15. hello.cpp:9:错误：‘app’在此作用域中尚未声明 
  16. hello.cpp:Atglobalscope: 
  17. hello.cpp:4:警告：未使用的参数‘argc’ 
  18. hello.cpp:4:警告：未使用的参数‘argv’ 
  19. make:***[hello.o]错误1

生成的Makefile有些问题:

  1. CC=gcc
  2. CXX=g++ 
  3. DEFINES=-DQT_NO_DEBUG-DQT_GUI_LIB-DQT_CORE_LIB 
  4. CFLAGS=-pipe-O2-Wall-W-D_REENTRANT$(DEFINES) 
  5. CXXFLAGS=-pipe-O2-Wall-W-D_REENTRANT$(DEFINES) 
  6. INCPATH=-I/work/program/dsk/qt-everywhere-opensource-src-4.6.1/mkspecs/l 
  7. inux-g++-I.-I/work/program/qtdevelop/include/QtCore-I/work/program/qtdevelop/ 
  8. include/QtGui-I/work/program/qtdevelop/include-I.-I.//这个路径是怎么生成的?. 
  9. LINK=g++ 
  10. LFLAGS=-Wl,-O1 
  11. LIBS=$(SUBLIBS)-L/work/program/qtdevelop/lib-lQtGui-lQtCore-lpth 
  12. read

简单文件运行出错：

  1. [root@localhostc++]#./a.out 
  2. -bash:./a.out:cannotexecutebinaryfile//刚开始出这个错是什么原因啊?重新编译后就正常了。。。 
  3. [root@localhostc++]#filea.out 
  4. a.out:ELF32-bitLSBexecutable,Intel80386,version1(SYSV),forGNU/Linux2.6.9,
  5.          dynamicallylinked(usessharedlibs),forGNU/Linux2.6.9,notstripped

修改Makefile之后，文件编译成功，但是运行仍然是报错的：

  1. [root@localhostqt]#make 
  2. g++-c-pipe-O2-Wall-W-D_REENTRANT-DQT_NO_DEBUG-DQT_GUI_LIB-DQT_CORE_LIB
  3.                        -I/work/program/dsk/qt-everywhere-opensource-src-4.6.1/mkspecs/linux-g++-I.
  4.                        -I/work/program/dsk/qt-everywhere-opensource-src-4.6.1/include/QtCore
  5.                        -I/work/program/dsk/qt-everywhere-opensource-src-4.6.1/include/QtGui
  6.                        -I/work/program/dsk/qt-everywhere-opensource-src-4.6.1/include-I.-I.-ohello.ohello.cpp

  10. [root@localhostqt]#./qt 
  11. ./qt:errorwhileloadingsharedlibraries:libQtGui.so.4:cannotopensharedobjectfile:Nosuchfileordirectory

100216 缺少这个动态链接库，如何办?： 可以直接在路径里加上吗?

设置完ld路径后，运行成功第一个Qt程序。。。：

现在的ld.so.conf.d下的qt配置内容如下：

ld设置后，基于Qt的应用启动不了。。。：

把/usr/lib/qt-3.3/lib注释掉，只配置下面的选项(运行基于qt-3.3的应用程序出错，在界面是跳出报错窗口)。

  1. avahi-qt3.i386:Qt3librariesforavahi//avahi是什么东西? 
  3. avahi-qt3-devel.i386:LibrariesandheaderfilesforavahiQt3development 
  4. pinentry-qt.i386:Passphrase/PINentrydialogbasedonQt 
  5. qt4.i386:ThesharedlibraryfortheQtGUItoolkit 
  6. qt4-devel.i386:DevelopmentfilesfortheQtGUItoolkit 
  7. qt4-doc.i386:APIdocumentation,demosandexampleprogramsforqt4 
  8. qt4-mysql.i386:MySQLdriversforQt'sSQLclasses 
  9. qt4-odbc.i386:ODBCdriversforQt'sSQLclasses 
  10. qt4-postgresql.i386:PostgreSQLdriversforQt'sSQLclasses 
  11. qt4-sqlite.i386:SQLitedriversforQt'sSQLclasses 
  12. qtnx.i386:QT4basedFreeNXClient

在命令行报出的错误则有些不同：

  1. avahi-qt3.i386:Qt3librariesforavahi//avahi是什么东西? 
  3. avahi-qt3-devel.i386:LibrariesandheaderfilesforavahiQt3development 
  4. pinentry-qt.i386:Passphrase/PINentrydialogbasedonQt 
  5. qt4.i386:ThesharedlibraryfortheQtGUItoolkit
