Quite a long post, but I think important for many of my ISV friends. I will update my post once I get an official technote from HCL about this new compiler recommendation. This week I figured out that already Domino 10 is build with Visual Studio 2017 instead of the old Visual Studio 2010 SP1 (VS2010 SP1) compiler. For Linux we got the official info, that beginning with Domino 10 we have to switch to the GCC compiler CentOS 7.4.

The syntax of specifying the notes.ini via =/local/notesdata/notes.ini is a cross platform feature I was aware of. But I didn't know how deep this is hooked into the Notes/Domino code. For the Domino core server tasks and client programs this is build-in by skipping the parameter when it starts with a = And the core takes automatically care of it.
