INSTALLING Qt/X11 Version 4.5.2.

INSTALLING Qt Source Package Version 4.6.0.

3
1. If you have the commercial edition of Qt, install your license
4
file as $HOME/.qt-license.
4
file as $HOME/.qt-license if you are on Unix. If you are on
5
Windows, copy the license file into your home directory
6
(this may be known as the userprofile environment variable) and
7
rename it to .qt-license. For example on Windows XP,
8
%USERPROFILE% should be something like C:\Documents and
6
11
For the open source version you do not need a license file.

2. Unpack the archive if you have not done so already:
15
On Unix (X11 and Mac):
11
17
gunzip %DISTNAME%.tar.gz # uncompress the archive
12
18
tar xvf %DISTNAME%.tar # unpack it
15
21
from the archive. We only support the GNU version of the tar
16
22
archiving utility. Note that on some systems it is called gtar.
24
On Windows, uncompress the files into the directory you want Qt
25
installed, e.g. C:\Qt\4.6.0.
27
NOTE: The install path must not contain any spaces.
29
4. Environment variables
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
34
On Windows, this is done by adding C:\Qt\4.6.0\bin
35
to the PATH variable. On Unix, this is done by adding
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.
42
In .profile (if your Unix shell is bash), add the following lines:
44
PATH=/usr/local/Trolltech/Qt-4.6.0/bin:$PATH
47
In .login (in case your Unix shell is csh or tcsh), add the following line:
49
setenv PATH /usr/local/Trolltech/Qt-4.6.0/bin:$PATH
51
If you use a different Unix shell, please modify your environment
52
variables accordingly.
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-4.6.0/lib. On Linux or Mac with GCC
57
this step is not needed.
20
63
To configure the Qt library for your machine type, run the
21
64
./configure script in the package directory.
23
66
By default, Qt is configured for installation in the
24
/usr/local/Trolltech/Qt-4.5.2 directory, but this can be
25
changed by using the -prefix option. Alternatively, the
26
-prefix-install option can be used to specify a "local"
27
installation within the source directory.
67
/usr/local/Trolltech/Qt-4.6.0 directory, but this can be
68
changed by using the -prefix option.
43
84
su -c "make install"
45
and enter the root password.
86
and enter the root password. On some systems, you have to use the
87
sudo command as follows:
91
and enter your password, this requires that you have administrator access
47
94
Note that on some systems the make utility is named differently,
48
95
e.g. gmake. The configure script tells you which make utility to
57
104
before running the configure script again.
59
4. Environment variables
61
In order to use Qt, some environment variables needs to be
64
PATH - to locate qmake, moc and other Qt tools
66
This is done like this:
68
In .profile (if your shell is bash, ksh, zsh or sh), add the
71
PATH=/usr/local/Trolltech/Qt-4.5.2/bin:$PATH
74
In .login (in case your shell is csh or tcsh), add the following line:
76
setenv PATH /usr/local/Trolltech/Qt-4.5.2/bin:$PATH
78
If you use a different shell, please modify your environment
79
variables accordingly.
81
For compilers that do not support rpath you must also extended the
82
LD_LIBRARY_PATH environment variable to include
83
/usr/local/Trolltech/Qt-4.5.2/lib. On Linux with GCC this step
106
4.2 Building on Windows
108
To configure the Qt library for your machine type:
114
Type "configure -help" to get a list of all available options.
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
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:
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
133
before running the configure script again.
86
135
5. That's all. Qt is now installed.
