How to Configure Qt (4.3.2) Environment on Linux Operating System

Download the open-source package: qt-x11-opensource-src-4.3.2.tar.gz. Extract: gunzip qt-x11-opensource-src-4.3.2.tar.gz tar xvf qt-x11-opensource-src-4.3.2.tar. Run the script: enter the qt-x11-opensource-src-4.3.2 directory and input ./configure to run the shell script, which tests the current system's essential configuration for software installation.

Download the open-source package: qt-x11-opensource-src-4.3.2.tar.gz

Extract: gunzip qt-x11-opensource-src-4.3.2.tar.gz

tar xvf qt-x11-opensource-src-4.3.2.tar

Run the script: Enter the qt-x11-opensource-src-4.3.2 folder and input ./configure to run the shell script program, which tests essential configuration information of the current system for software installation.

Compile: gmake

Install: gmake install

Environment variables: Edit /etc/profile using vi, and append the following lines at the end of the file:

PATH=/usr/local/Trolltech/Qt-4.3.2/bin:$PATH
QTDIR=/usr/local/Trolltech/Qt-4.3.2
MANPATH=$QTDIR/man:$MANPATH
LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

export PATH QTDIR MANPATH LD_LIBRARY_PATH

After rebooting, the configuration is complete. Write a simple HelloQt program to verify whether the setup was successful. Then run qmake -project to generate the project file, use qmake on the generated .pro file to produce the Makefile, and finally run make to generate the executable.

Notes:

During the gmake process, errors may occur indicating that krb5.h cannot be found. To resolve this issue, execute the following commands:

ln -s /usr/kerberos/include/com_err.h /usr/include/com_err.h

ln -s /usr/kerberos/include/profile.h /usr/include/profile.h

ln -s /usr/kerberos/include/krb5.h /usr/include/krb5.h

If Linux is installed on a virtual machine, it may appear that mount cannot detect the Windows hard drive. To copy files between Linux and Windows file systems, first install VMware Tools: Virtual Machine -> Install VMware Tools; then cd /mnt/cdrom and run the ./vmware-install.pl script; finally, go to Virtual Machine -> Settings -> Options -> Shared Folders to create a shared folder (corresponding to /mnt/hgfs in Linux) for file exchange between Linux and Windows.
