Official moOde 7.1.0 support thread

[TheOldPresbyope]

I wouldn't be surprised if compiling something like upmpdcli on a single core Pi takes like 2 or 3 hours or maybe even longer :-0

I gave up after 80 minutes

The problem is that update forces 4 tasks for compilation with "make -j4". RPi Zero shows like load average above 10, full memory in use and kswapd0 as a top CPU consumer. Would be nice to configure update script for low memory or single CPU.

It would prolly be same on a single core w/o -J4. I remember when we had to compile librespot on an ARM6 and it took like 4 or 5 hours.

The -j4 option cuts compile time roughly in half on multi-core ARM's and so the decision to use it in the in-place update for the complex upmpdcli and libupnpp-bindings was made to benefit the ARM7 population which I'm guessing is the platform the majority of moOde users are running.

I suppose for single-core Pi's the recommendation would be to use the image instead of the in-place update. I'll update the instructions.

FYI:

Compiling on the 512MB Raspberry Pi 3A+ takes a long time too even though it has 4 ARM7 cores. Free memory drops so much the scheduler has trouble switching processes. Trying to monitor progress with 'moodeutl -t' or even asking for 'free' is agonizingly slow, so I don't.

Result: 7h24m to complete the update, almost all of which consumed during the two compilations.
