Ubuntu12.04 (64bit) Installation QT4 summary

This article mainly introduces the installation of Linux system Ubuntu12.04 (64bit) under Qt4.8.5, which also involves the installation of Fedora9 under QT4.

1, download software : Go to Qt's official website download Qt4.8.5 and QT Creator software , download the specific software as follows:

• Qt4.8.5 Software: qt-everywhere-opensource-src-4.8.5.tar.gz
• Qt Creator Software: qt-creator-linux-x86_64-opensource-2.5.2.bin

2, decompression qt-everywhere-opensource-src-4.8.5.tar.gz, can be extracted to the current directory:

sudo tar xvzf qt-everywhere-opensource-src-4.8. 5. tar. gz

3, compile the configuration Qt4.8.5: Enter the qt-everywhere-opensource-src-4.8.5 directory, the compilation configuration:

./configure

Ubuntu12.04 (64bit) configuration error, because the pure version of Ubuntu is not g++, need to install first:

sudo Install g++

Compiling again will cause errors, similar to the following:

Basic XLIB functionality Test failed!   in/home/gcgily/qt-everywhere-opensource-src-4.8. 2/mkspecs/linux-g++

Or

g++-wl,-o1-o xlib xlib.o    -l/usr/x11r6/lib-lxext-lx11-lm  /usr/bin/ldFind - Lxext

At this point, you need to install the Libx11-dev Libxext-dev libxtst-dev three packages:

sudo Install Libx11-dev libxext-dev Libxtst-dev

After the installation is complete, execute the./configure to compile successfully.

4. Make: Execute. After successful/configure, there will be a next hint: Execute make and do install ( prompt gmake and gmake install in Fedora9), at which point we execute:

Make

It will take a long time to wait for the run to complete.

5, make install: Execute the Make install command, this time requires root user rights support:

sudo  Make Install

It will also take a long time.

6. Set Environment variables : Add the following script to the current user. bashrc file:

###################    Setting the QT environment variable    ############### #export PATH= $PATH:/usr/local/trolltech/qt-4.8 . 5/bin:/usr/local/trolltech/qt-4.8. 5/includeexport qtdir=/usr/local/trolltech/qt-4.8. 5

Then, update the. bashrc file:

source. BASHRC

at this point, Qt4.8.5 Software Installation is complete.
