I download the start(PortableAppsStartSource21.2.2.7z) source code from SF, and want to modify and customize it.
It seems the code is in Pascal, and I installed the Lazarus IDE, but it doesn't know the source code project.
What is the IDE is used to compile the code? Any guide to build it?
The platform is built using Embarcadero's Delphi IDE.
This is also what the start executable is developed in.
The 22.0 Beta 1 version of the platform was built using Delphi 11.1.
I myself have started exploring assisting in development of the platform itself, using the Delphi Community Edition, however have not been able to dedicate much time to it recently.
[EDIT] Also note that the Community Edition is using the 10.4.2 version of Delphi, not the newly-released 11.1, as the Community Edition tends to lag behind the paid products.
John will likely have further insight.
