There are 8 cores by the way

#

Sorry, 4 cores, but 8 logical processors or whatever the terminology is

proud orbit Oct 2, 2024, 5:41 PM

#

have you tried make -j or make -j4. That will use multiple cores at once

#

see https://learn.adafruit.com/building-circuitpython/build-circuitpython#use-all-your-cpus-when-building-3086075

graceful lintel Oct 2, 2024, 5:42 PM

#

I've done -j12 so far, but I guess thats maybe too much

proud orbit Oct 2, 2024, 5:44 PM

#

too much won't make that much difference. something else would appear to be wrong. If the fan is not working well or a filter is clogged, it could be overheating and clocking down. There are tools in Windows that will monitor the CPU temp

#

this is a laptop CPU, so it's not that high speed, but it shouldn't be that bad

#

yours vs mine: https://www.cpubenchmark.net/compare/3042vs3099/Intel-i5-8250U-vs-Intel-i7-8700

#

you might consider making the laptop be dual boot to Ubuntu if you don't have another use for it

folks have also use the github hosted workspace for circuitpython dev too I think

I actually have dual boot already, I just haven't used it in years, so I'd rather avoid brushing the dust off that old ghost town 😅

#

The ubuntu partition is not on an SSD though, if I remember correctly.

#

It was a bit faster this last time I tried to compile. Took around 5 min before I got a syntax warning/compiler error. Havent been able to see any problems with CPU temperature

mental spoke Oct 2, 2024, 5:55 PM

#

repeated builds should be pretty fast. what is the warning you got?

graceful lintel Oct 2, 2024, 5:57 PM

#

Yeah, that's what I was hoping for, however this is the first time (in 5 or so attempts) I've been able to get feedback within a "timely manner" on my poor code, so I was just about to give up entirely. I guess you can tell I'm not that used to C++ programming, so I rely heavily on the compiler telling me that something is wrong on line x 😛

#

In this case it was this error if it matters:

../../shared-module/synthio/__init__.c:214:24: error: incompatible types when assigning to type '_Bool' from type 'synthio_block_slot_t' {aka 'struct synthio_block_slot'}
  214 |         playback_dir = note->playback_direction;

#

After doing a clean it will be slower

#

There is an analysis at the start of the build that may be slow to redo too if it breaks then

#

usually due to incorrect header includes

graceful lintel Oct 2, 2024, 6:03 PM

#

Yeah, I didn't really do much except adding semicolons and such between my builds, which is why I was looking for a faster way to build. I've just started another build now, so I'll see if the problem has sorted itself out in a little while.

proud orbit Oct 2, 2024, 6:04 PM

#

and make sure you are really running on the SSD

graceful lintel Oct 2, 2024, 6:09 PM

#

Nothing wrong with the temperature at least. And I am running on the SDD:

#

Took around 5 minutes this time (and it actually compiled 😲 )

proud orbit Oct 2, 2024, 6:12 PM

#

which board are you compiling?

graceful lintel Oct 2, 2024, 6:13 PM

seeeduino_xiao_rp2040

proud orbit Oct 2, 2024, 6:21 PM

#

i don't understand why it was 5 minutes now and 30 minutes previously. Was the 5 minutes from a clean build?

graceful lintel Oct 2, 2024, 6:27 PM

#

At least one of them was, but I did those last week so I don't remember all the details. This time I closed pretty much everything else I was doing on the computer too, so that may have some part in the explanation.

proud orbit Oct 2, 2024, 6:28 PM

#

also is windows all updated? Is it win10 or 11?

graceful lintel Oct 2, 2024, 6:36 PM

#

Win 10. Should be up to date
