|
|
28 | 28 | make uninstall |
|
|
29 | 29 | |
|
|
30 | 30 | Configure project with qmake and build project with make: |
|
|
31 | 31 | (Linux) make |
|
|
32 | 32 | (Windows with MinGw) mingw32-make |
|
|

|
36 | 36 | For debug builds: |
|
|
37 | 37 | qmake CONFIG+=debug; make |
|
|
38 | 38 | or |
|
|
39 | 39 | qmake CONFIG+=debug_and_release; make debug |
|
|
40 | 40 | |

43 | 43 | or |
|
|
44 | 44 | qmake CONFIG+=debug_and_release; make release |
|
|
45 | 45 | |
|
|
46 | 46 | For both builds |
|
|
47 | 47 | qmake CONFIG+="debug_and_release build_all"; make |
|

55 | 55 | Building as a statically linked library |
|
|
56 | 56 | ======================================= |
|
|
57 | 57 | |
|
|
58 | 58 | The same as above applies you will just have to add staticlib to the CONFIG: |
|
|
59 | 59 | qmake CONFIG+=staticlib |
|

|
|
102 | 102 | Known Issues |
|
|
103 | 103 | ============ |
|
|
104 | 104 | - Automatic scaling of the axes is only done when you add a series on a chart |
|
|
105 | 105 | - DateTimeAxis is not supported on ARM because of floating point precision |
|
|
106 | 106 | issues (qreals are floats) |
|
|
107 | 107 | - Declarative plugin is available from Qt 4.7.4 onwards because of missing |
|
|
108 | 108 | Q_REVISION macro in the earlier Qt releases |
|
|
109 | - Defining axis min-max values sometimes affects other axes with the same orientation | |
|
|
110 | - See for example the secondary y-axis of QML Weather demo application | |
|
|
111 | - The work-around is to set axis range dynamically instead of initializing min and | |
|
|
112 | max properties to certain values | |
