My apologies.

After some testing, i found that when the dbg file is in the same dir as
the executable, the calltrace is show with lineinfo. Seems that fpc
generates code to find the debug info.

El 11/02/16 a les 04:12, Martin ha escrit:


info symbol 0x54320 and it prints what is at that address. Do that for
each address in the trace.


That should be "info line *0x54320".

Hi,

I compiled a program with -Xg (generating an external debug info file *.dbg)

And deployed the executable without the debug info

When an exception occurs i get a backtrace with only addresses

How to get the line number, method names of the backtrace using the external
debug file?


my first eWAG gut response is to distribute the DBG file with the executable...

Thanks

But that will not help, the backtrace will still be generated without info,
just address
