13 2.  Unpack the archive if you have not done so already:

    14 

    15     On Unix (X11 and Mac):

    16         cd /tmp

    17         gunzip %DISTNAME%.tar.gz        # uncompress the archive

    18         tar xvf %DISTNAME%.tar          # unpack it

    19 

    20     This creates the directory /tmp/%DISTNAME% containing the files

    21     from the archive. We only support the GNU version of the tar

    22     archiving utility. Note that on some systems it is called gtar.

    23 

    24     On Windows, uncompress the files into the directory you want Qt

    25     installed, e.g. C:\Qt\%VERSION%.

    26 

    27     NOTE: The install path must not contain any spaces.

    28 

    29 4. Environment variables

    30 

    31    In order to build and use Qt, the PATH environment variable needs

    32    to be extended to locate qmake, moc and other Qt tools

    33 

    34    On Windows, this is done by adding C:\Qt\%VERSION%\bin

    35    to the PATH variable. On Unix, this is done by adding

    36    /tmp/%DISTNAME%.

    37 

    38    For newer versions of Windows, PATH can be extended through

    39    "Control Panel->System->Advanced->Environment variables" and for

    40    older versions by editing C:\autoexec.bat.

    41 

    42    In .profile (if your Unix shell is bash), add the following lines:

    43 

    44         PATH=/usr/local/Trolltech/Qt-%VERSION%/bin:$PATH

    45         export PATH

    46 

    47    In .login (in case your Unix shell is csh or tcsh), add the following line:

    48 

    49         setenv PATH /usr/local/Trolltech/Qt-%VERSION%/bin:$PATH

    50 

    51    If you use a different Unix shell, please modify your environment

    52    variables accordingly.

    53 

    54    For some X11 compilers that do not support rpath you must also

    55    extended the LD_LIBRARY_PATH environment variable to include

    56    /usr/local/Trolltech/Qt-%VERSION%/lib. On Linux or Mac with GCC

    57    this step is not needed.

    58 

    59 4.  Building

    60 

    61 4.1 Building on Unix

    62 

    63     To configure the Qt library for your machine type, run the

    64     ./configure script in the package directory.

    65 

    66     By default, Qt is configured for installation in the

    67     /usr/local/Trolltech/Qt-%VERSION% directory, but this can be

    68     changed by using the -prefix option.

    69 

    70         cd /tmp/%DISTNAME%

    71         ./configure

    72 

    73     Type "./configure -help" to get a list of all available options.

    74 

    75     To create the library and compile all the demos, examples, tools,

    76     and tutorials, type:

    77 

    78         make

    79 

    80     If you did not configure Qt using the -prefix-install option,

    81     you need to install the library, demos, examples, tools, and

    82     tutorials in the appropriate place. To do this, type:

    83 

    84         su -c "make install"

    85 

    86     and enter the root password. On some systems, you have to use the

    87     sudo command as follows:

    88 

    89         sudo make install

    90 

    91     and enter your password, this requires that you have administrator access

    92     to your machine.

    93 

    94     Note that on some systems the make utility is named differently,

    95     e.g. gmake. The configure script tells you which make utility to

    96     use.

    97 

    98     If you need to reconfigure and rebuild Qt from the same location,

    99     ensure that all traces of the previous configuration are removed

   100     by entering the build directory and typing

   101 

   102         make confclean

   103 

   104     before running the configure script again.

   105 

   106 4.2 Building on Windows

   107 

   108     To configure the Qt library for your machine type:

   109 

   110         C:

   111         cd \Qt\%VERSION%

   112         configure

   113 

   114     Type "configure -help" to get a list of all available options.

   115 

   116     If you are using the "-direct3d" option, make sure that you have

   117     the Direct3D SDK installed, and that you have run the

   118     %DXSDK_DIR%\Utilities\Bin\dx_setenv.cmd command, before attempting

   119     to run configure.

   120 

   121     The actual commands needed to build Qt depends on your development

   122     system. For Microsoft Visual Studio to create the library and

   123     compile all the demos, examples, tools and tutorials type:

   124 

   125         nmake

   126 

   127     If you need to reconfigure and rebuild Qt from the same location,

   128     ensure that all traces of the previous configuration are removed

   129     by entering the build directory and typing

   130 

   131         nmake confclean

   132 

   133     before running the configure script again.

   134 

   135 5.  That's all. Qt is now installed.

   136 

   137     If you are new to Qt, we suggest that you take a look at the demos

   138     and examples to see Qt in action. Run the Qt Examples and Demos

   139     either by typing 'qtdemo' on the command line or through the

   140     desktop's Start menu.
