27 27 QtCommercial Charts, you should first uninstall it with
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
33 33 (Visual Studio) nmake
34 34 (OSX) make
35 35
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
41 41 For release builds:
42 42 qmake CONFIG+=release ; make
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
48 48
49 49 If you want to install the libraries to your Qt library directory use:
50 50 make install
51 51
52 52 If you want to uninstall the libraries
