Building Polyphone for Mac OS X

Use these instructions if you cannot install Polyphone on your Mac OS X with the available installers in the section “Download”.

Prerequisite

The following applications are required:

Xcode (available in the Apple Store),
Qt Creator with its framework .

You also need the sources of Polyphone, available here or on GitHub , along with the necessary libraries you can download here.

For correctly opening a project with Qt Creator, it must first be given the permission to read all files from your computer (in "Security and privacy" => "Full disk access" => add "Qt creator.app" which is in its installation directory).

If some of the previously provided libraries are not up to date or not compatible with the version of Mac, like SSL for example, it will be necessary to look for their sources on the internet and to recompile them by enabling a static linking:

configure --enable-static --disable-shared --prefix=...
make
make install

Then copy all .h (headers) and .a (static libraries).

Build

Unzip the libraries and place the directory lib_mac just next to the directory sources.

Open the file polyphone.pro with Qt Creator. Build the project, a bundle polyphone.app should appear in the directory lib_mac.

If the SDK path cannot be resolved, try modifying the file polyphone.pro to include these variables (adjust the Mac OSX version of first):

QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.15
QMAKE_MAC_SDK = macosx10.15

Complete the bundle

Run the following command to include libraries and frameworks inside the bundle (adjust the path first!):

/Path/To/Qt/5.2.0/clang_64/bin/macdeployqt /Path/To/lib_mac/polyphone.app

Copy the framework Jackmp from lib_mac and paste it to lib_mac/polyphone.app/Contents/Frameworks. You may need to right click and select View content to go inside the bundle instead of executing it.

Finally, run the following command in a single line (adjust the last path first!):

install_name_tool -change /System/Library/Frameworks/Jackmp.framework/Versions/A/Jackmp @executable_path/../Frameworks/Jackmp.framework/Versions/A/Jackmp /Path/To/lib_mac/polyphone.app/Contents/MacOS/Polyphone

You can then execute the program or compress it as a .zip file to share it.
