Hi,
1. Your function shall be in the functions.js file , e.g. in:
/yourproject/qbs/imports/YourFunctions/functions.js
2. Also your Project should have an option:
Project {
...
qbsSearchPaths: "qbs"
...
}
3. Your Product's file should contains:
...
import YourFunctions
...
...
property string gnuToolsDir: YourFunctions.findGnuToolsDir();
...
I would make it so. Also you can look how this done by analogy, e.g. in
QtCreator's sources.
BR,
Denis
