You can download the Qt 5 sources from the Downloads page. For more information, visit the Getting Started with Qt page.
Qt for X11 has some requirements that are given in more detail in the Qt for X11 Requirements document.
If you have the commercial edition of Qt, install your license file as $HOME/.qt-license
.
For the open source version you do not need a license file.
Unpack the archive if you have not done so already. For example, if you have the qt-everywhere-opensource-src-%VERSION%.tar.gz
package, type the following commands at a command line prompt:
cd /tmpgunzip qt-everywhere-opensource-src-%VERSION%.tar.gz # uncompress the archivetar xvf qt-everywhere-opensource-src-%VERSION%.tar # unpack it
This creates the directory /tmp/qt-everywhere-opensource-src-%VERSION%
containing the files from the archive. We only support the GNU version of the tar archiving utility. Note that on some systems it is called gtar.
To configure the Qt library for your machine type, run the ./configure
script in the package directory.
By default, Qt is configured for installation in the /usr/local/Qt-%VERSION%
directory, but this can be changed by using the -prefix
option.
cd /tmp/qt-everywhere-opensource-src-%VERSION%./configure
The Configure Options page contains more information about the configure options.
To create the library and compile all the examples, tools, and tutorials, type:
make
If -prefix
is outside the build directory, you need to install the library, examples, tools, and tutorials in the appropriate place. To do this (as root if necessary), type:
make install
Note that on some systems the make utility is named differently, e.g. gmake. The configure script tells you which make utility to use.
Note: If you later need to reconfigure and rebuild Qt from the same location, ensure that all traces of the previous configuration are removed by entering the build directory and typing make confclean
before running configure
again.
In order to use Qt, some environment variables needs to be extended.
PATH - to locate qmake, moc and other Qt tools
This is done like this:
In .profile
(if your shell is bash, ksh, zsh or sh), add the following lines:
PATH=/usr/local/Qt-%VERSION%/bin:$PATHexport PATH
In .login
(in case your shell is csh or tcsh), add the following line:
setenv PATH /usr/local/Qt-%VERSION%/bin:$PATH
If you use a different shell, please modify your environment variables accordingly.
For compilers that do not support rpath you must also extended the LD_LIBRARY_PATH
environment variable to include /usr/local/Qt-%VERSION%/lib
. On Linux with GCC this step is not needed.
