How to get debug information?
There is an error, but only adresses are shown.
How/ Where are the addresses shown?
The addresses were shown in the output window (console).
Runtime error 207 at $0808BE90

Ok: those addresses *should* get names, if you compile with -gl AND do
not in any form strip (strip.exe removes the debug info) your app
An app containing debug info has a considerable bigger exe.
(can be 10 times or more as big as without)
if you make a copy of your exe, and run
strip[.exe] the_copy
the the copy should be much smaller
On windows strip.exe is in the fpc bin directory
BUT only up to the very first time it does encounter an address that can
not be resolved. Once that has happened no further addresses are resolved.
I do not understand exactly what that means.
If you get it to work, and one of the addresses is in the RTL (assuming
your RTL has no dobug info), or in the kernel then the translation
simply stops.
It could be that the top address is in the rtl, then you will never get
the info
you can use gdb (assuming there is debug info / check the exe size)
gdb your_exe
and inside gdb
info symbol *0x0808BE90
Not all symbols may resolve though
------------------
You can (again assume debug info) run in gdb
gdb your_exe
break FPC_RUNERROR
r
and when stopped
bt
