Runtime error 217 when launching Delphi FMX Linux 64-bit application (RAD Studio 12, Ubuntu 22.04)

[dmitrybv 5]

I’m having trouble running my Delphi FMX application on Linux 64-bit (Ubuntu 22.04.4 LTS, FmxLinux 1.78).

• The application runs fine on Win32, Win64, Android-64, macOS-64.

• On Linux 64-bit, when I try to start it in debug mode, the IDE immediately stops execution without showing any error. PAServer doesn’t print anything either.

• A simple test app (just one form with a button) runs without issues on Linux.

• My real project has several dozen forms. When I run it in debug mode in Embarcadero RAD Studio 12 (Version 29.0.55362.2017), the debugger just stops with no messages.

• If I try “Run without debugging”, PAServer prints:

  Runtime error 217 at 00000000012AFEFC 

According to ChatGPT, this usually means the crash happens inside the initialization section of one of the units included in the project’s uses.

👉 My question: What’s the best way to identify which unit or initialization block is causing the crash on Linux, and how can I debug this further?

If I place a breakpoint in the initialization section of the very first unit in my project, the debugger hangs when exiting the method

procedure System.StartUpCopy.CopyStartUpFiles;
