Introduction to Qt4/opt

Qt is a comprehensive development framework that includes an extensive array of features, capabilities and tools that enable development of high-performance, cross-platform rich-client and server-side applications. Qt is the GUI framework on which KDE4 is built and Qt4 is the version of Qt that the KDE4 uses. You can of course use Qt for non-KDE applications as well, but if you wish to use KDE4 or any KDE4-based applications, you must have Qt4 installed on your system.

Dependencies

Required

• X Window System

Optional

• CUPS
• D-BUS
• Firebird
• FontConfig
• FreeType
• Glib2
• GStreamer
• libjpeg
• libmng
• libpng
• LibTIFF
• MySQL
• NAS
• OpenSSL
• PostgreSQL
• SQLite
• SQLite3
• unixODBC
• Xinerama provided by and X Window System
• Xfixes provided by and X Window System

Configuration Information

If you would like to compile with MySQL support add the following to the configure command:

-plugin-sql-mysql -I/usr/include/mysql

If you would like to compile with PostgreSQL support add the following to the configure command:

-plugin-sql-psql -I/usr/include/postgresql/server

If you would like to compile with SQLite support add the following to the configure command:

-plugin-sql-sqlite2 -system-sqlite

If you would like to compile with SQLite3 support add the following to the configure command:

-plugin-sql-sqlite -system-sqlite

If you would like to compile with unixODBC support add the following to the configure command:

-plugin-sql-odbc

If you would like to compile with NAS support add the following to the configure command:

-system-nas-sound

If you would like to disable Qt 3 support functionality add the following to the configure command:

-no-qt3support

If you would like to disable QtWebKit module add the following to the configure command:

-no-webkit

If you would like to disable linking Qt libraries and executables using the library install path as a runtime library path add the following to the configure command:

-no-rpath

If you don't need qtxmlpatterns add the following to the configure command (since only qtxmlpatterns requires this):

-no-exceptions

If your X Window System is NOT Xorg, then add to configure:

-no-xfixes

If you want optimized qmake tool add the following to the configure command:

-optimized-qmake

If you would like to disable GLib event loop (which is known to be buggy) add the following to the configure command:

-no-glib

Note

Also you can disable GLib event loop at runtime by setting NO_GLIB environment variable to 1.

If you don't want to compile demos (save compile time) add the following to the configure command:

-nomake demos

If you don't want to compile examples (save compile time) add the following to the configure command:

-nomake examples

If your GCC is NOT gcc4 you probably need to disable visibility explicitly. Just add the following to the configure command:

-no-reduce-exports

Note

Qt3 does not use DESTDIR, it uses INSTALL_ROOT for the same purpose. Use INSTALL_ROOT as you would normally use DESTDIR.

Non-Multilib

If you're X Window System prefix is something other then /usr/X11R6 then run the following command to change the hard coded paths in the sources:

for file in $(grep -lr "X11R6" *)
do
  sed -i "s@/usr/X11R6@${XORG_PREFIX}@g" $file
done

Make changes for pure64 systems:

for file in $(grep -lr "/lib64" *)
do
  sed -i "s@/lib64@/lib@g" $file
done

Compile the package:

mkdir -v /opt/qt-4.8.5 &&
ln -v -sfn qt-4.8.5 /opt/qt4 &&
./configure -prefix /opt/qt4 \
    -libdir /opt/qt4/lib \
