Use these instructions to know how to build Polyphone with Qt Creator. It is assumed you already have on your computer Qt Creator installed with the Qt framework, a compiler and the necessary dependencies to build Polyphone (see related pages for this).
The following elements are required
The instructions for installing them are dependent on the OS you are using, see the related documentation pages for this.
Get Polyphone Soundfont Editor sources from here.
First modify polyphone.pro to use distributed versions for rtmidi, stk and qcustomplot. Uncomment the following lines by removing the leading ‘#’:
DEFINES += USE_LOCAL_RTMIDI
DEFINES += USE_LOCAL_STK
DEFINES += USE_LOCAL_QCUSTOMPLOT
You can skip these modifications if you want to use libraries already installed in your computer (make sure you have them!).
Start Qt Creator and open the file "polyphone.pro".
Then configure the project.
Go in the menu "Build" and choose the item "Run qmake".
Qmake run is finished when the proceeding bar on the bottom right corner has reached the 100% green.
In the section "Project" in the left column, then in the section "Build&Run", select the build configuration (Release is preferred) and uncheck "Shadow build".
Finally, click on the action "Build project Polyphone" in the menu "Build".
During project build you should see warnings but no errors.
Now you should have the executable polyphone either in the RELEASE or DEBUG subfolder of the source code, depending on your choice in QtCreator build configuration.
Please you the forum if you need more information or for getting some help.
