QTLinux installation manual

The installation manual under QTLinux-general Linux technology-Linux programming and kernel information. The following is a detailed description. Specific installation methods:

1. Download Qt 4.4.0 for X11 OpenSource.

2. Download The qt-x11-opensource-src-4.4.0.tar.gz file, we use the tar command to decompress it.

Tar zxvf qt-x11-opensource-src-4.4.0.tar.gz

3. Move the directory to the/usr/local directory, or the catalog directory to the/home directory. The following installation process is to move the directory to the/usr/local directory, change the name to qt. If you have not moved it, pay attention to the directory when setting it.

4. Modify the. bash_profile or. profile or/etc/profile file in the directory (you can use the vi editor or gedit) and add the following code:

QTDIR =/usr/local/qt
PATH = $ QTDIR/bin: $ PATH
MANPATH = $ QTDIR/man: $ MANPATH
LD_LIBRARY_PATH = $ QTDIR/lib: $ LD_LIBRARY_PATH
Export qtdir path manpath LD_LIBRARY_PATH

5. log out of the user or source. bash_profile to make the configuration file take effect.

6. Go to the QT directory and start compiling.

./Configure

Enter yes to agree to the GPL/QPL protocol. You can also see this command./configure-thread on the network. To support multithreading, you should just tap these commands. (I don't know if the./configure-thread and./configure commands are repeated)

7. It takes an hour or two to start making.

Make

8. Start install. (If some manuals on the Internet do not have this step, the error "error while loading shared libraries: libQTDesignerComponents. 44. after I make install it, it will be OK .) This step takes a long time. It may take several minutes.

Make install

9. Go to the QT directory, enter the bin directory, and run./designer. You can see the graphic interface.
