(c) seems the most appropriate way to allow for decent debugging

One of the options in the lazarus debugger settings is "GDB debugger
through SSH".
I'll try to find instructions on this and try to install the gdb
"stub" on the QNAP and test this combination ASAP. (SSH already is
in place on the QNAP.)
Remote debugging with gdb on the command line also works
well for many years.
Do you mean independently of Lazarus and fpc ?
I already did test this with C programming and I all the time use
Eclipse to debug embedded software via a USB-JTAG adapter which
AFAIK for gdb and the system that controls gdb (here: Eclipse, but
could be Lazarus as well) is identically to remote debugging via
ICP/IP..
You're not "stuck".
Of course I am not really stuck. :-) :-) .
The program already does work nicely on the Linux PC server and I
suppose I in fact don't need to debug it on the ARM. I just need
to compile it. And here I have the choice to install fpc on the
QNAP (should be possible: I already successfully did install gcc).
But I understand that installing fpc on the ARM is done by
cross-compiling the compiler on a PC. So it seems even easier to
cross-compile the user program itself.
So
"Cross-compile app every time"
is easier/better than
"Compile cross compiler once and work natively as of then"
?
That is a weird assumption. I would go for the second one, hands
down...
I wouldn't if the second one is significantly slower than the first
one. Otherwise I'd agree :)
On old hardware, maybe, but these days ?
I still have an old arm development board with around 200MHz... and I
also don't know (yet) how my new m68k/coldfire board performs (also 200MHz).

Sven
