I wish I had the answer.
If you have files that compiled before (simple).. You might try
corrupting them in a small way.. Do a recompile on the copied file..
Or, if you are making your program from modules, kick one out to isolate
what is causing the failure.
At a loss.. I'm not working with that stuff yet (too many computer
crashes)!

Hi,
it's just a warning, but could someone explain what:
"/usr/lib64/gcc/avr/7/ld: warning: -z relro ignored"
is trying to tell me. It appeared with a newer compiler version.
Thanks,
Bob
OK, it it a feature to make relocated code read-only under certain
circumstances (does not apply to my AVR Mega1284). It seems to be built
into the avr-ld linker program.
issuing "avr-ld" gives:
avr-ld: warning: -z relro ignored
avr-ld: no input files
So the linker seems to have this default.
I suspected it because an old program compiled with avr-gcc 4.9.2 does
not run when compiled with version 7.4.0, although it compiles without
error. I will have to dig deeper.
Cheers,
Bob
