45 | \title Deploying Qt for Embedded Linux Applications
|
---|
46 | \ingroup qt-embedded-linux
|
---|
47 |
|
---|
48 | The procedure of deploying an Qt application on \l{Qt for Embedded Linux}
|
---|
49 | is essentially the same as the deployment procedure on X11 platforms
|
---|
50 | which is described in detail in the \l {Deploying an Application
|
---|
51 | on X11 Platforms} documentation. See also the \l {Deploying Qt
|
---|
52 | applications}{general remarks} about deploying Qt applications.
|
---|
53 |
|
---|
54 | In addition, there is a couple of Qt for Embedded Linux specific issues to
|
---|
55 | keep in mind:
|

|

|
---|
59 | \section1 Fonts
|
---|
60 |
|
---|
61 | When Qt for Embedded Linux applications run, they look for a file called
|
---|
62 | \c fontdir in Qt's \c /lib/fonts/ directory defining the
|
---|
63 | fonts that are available to the application (i.e. the fonts
|
---|
64 | located in the mentioned directory).
|
---|
65 |
|
---|
66 | For that reason, the preferred fonts must be copied to the \c
|
---|
67 | /lib/fonts/ directory, and the \c fontdir file must be customized
|
---|
68 | accordingly. See the \l {Qt for Embedded Linux Fonts}{fonts} documentation
|
---|
69 | for more details about the supported font formats.
|
---|
70 |
|
---|
71 | Note that the application will look for the \c /lib/fonts/
|
---|
72 | directory relative to the path set using the \c -prefix parameter
|
---|
73 | when running the \c configure script; ensure that this is a
|
---|
74 | sensible path in the target device environment. See the
|
---|
75 | \l {Installing Qt on Embedded Linux#Step 3: Building the
|
---|
76 | Library}{installation} documentation for more details.
|
---|
77 |
|
---|
78 | \section1 Environment Variables
|
---|
79 |
|
---|
80 | In general, any variable value that differs from the provided
|
---|
81 | default values must be set explicitly in the target device
|
---|
82 | environment. Typically, these include the QWS_MOUSE_PROTO,
|
---|
83 | QWS_KEYBOARD and QWS_DISPLAY variables specifying the drivers for
|
---|
84 | pointer handling, character input and display management,
|
---|
85 | respectively.
|
---|
86 |
|
---|
87 | For example, without the proper mouse and keyboard drivers, there
|
---|
88 | is no way to give any input to the application when it is
|
---|
89 | installed on the target device. By running the \c configure script
|
---|
90 | using the \c -qt-kbd-<keyboarddriver> and \c
|
---|
91 | -qt-mouse-<mousedriver> options, the drivers are enabled, but in
|
---|
92 | addition the drivers and the preferred devices must be specified
|
---|
93 | as the ones to use in the target environment, by setting the
|
---|
94 | environment variables.
|
---|
95 |
|
---|
96 | See the \l{Qt for Embedded Linux Pointer Handling}{pointer handling},
|
---|
97 | \l{Qt for Embedded Linux Character Input}{character input} and
|
---|
98 | \l{Qt for Embedded Linux Display Management}{display management}
|
---|
99 | documentation for more information.
|
---|
100 |
|
---|
101 | \section1 Framebuffer Support
|
---|
102 |
|
---|
103 | No particular actions are required to enable the framebuffer on
|
---|
104 | target devices: The Linux framebuffer is enabled by default on all
|
---|
105 | modern Linux distributions. For information on older versions, see
|
---|
106 | \l http://en.tldp.org/HOWTO/Framebuffer-HOWTO.html.
|
---|
107 |
|
---|
108 | To test that the Linux framebuffer is set up correctly, and that
|
---|
109 | the device permissions are correct, use the program provided by
|
---|
110 | the \l {Testing the Linux Framebuffer} document.
