IDE 2.3.6 freezes during verify/compile

Development Tools IDE 2.x
1

Every time I try to verify or compile, I get a message ‘compiling’ and the activity bar moves about half way, then freezes and I have to abort to do anything else. I have selected for a verbose output and attached the output. I have tried un-installing and re-installing but no change. Hoping someone can help me out…

You appear to be using a lot of libraries. Give it more time. If things are set up wrong then we have heard of 26min compiles. What computer Win or Mac are you using?

Thanks for your reply. I’m on a windows 10 PC (64 bit). I’m new to this so I have no idea why it would be using so many libraries. I’ve just installed the IDE and am attempting to compile the simple sketch to blink the in-built LED on a Uno (R3). I wouldn’t expect that to require many libraries?

I have found that I can’t close the IDE afterwards, other programs a slow or eratic and I have to force the PC to re-boot via the power switch to regain stability again. I could try waiting 26mins for a compile but that seems slow for such a small sketch.

It's not the libraries. The compile process seems to be stuck in the compiling of the core.

Comparing your output with one from my system, it's does not get to compiling the last file.

That last one is missing in your output. I do not know why, the previous process (compiling wiring_pulse.c) hasn't completed. It might be a virus scanner that slows down the process. If that is the case you can whitelist the Arduino15 directory.

Although unlikely it can also be a corrupt installation of the core. To solve that you can downgrade the AVR board package using the board manager to e.g. version 1.8.3, test and next upgrade it again.

Note:
I compiled an empty sketch, not blink; it should not make a difference.

It is totally bizarre behaviour. Why it is trying to compile the core is a mystery to me.

6

This is the expected behavior.

The first time you perform a compilation for a given board configuration, the core is compiled. If that compilation is successful, the resulting objects are cached and reused as appropriate for subsequent compilations for that board (unless there has been a change to the core source files, as would occur after you updated the board's platform). However, if the compilation never completed, then the core cache will not have been generated, and thus it is necessary to attempt to compile the core once again on the subsequent compilation.

Just tested it with Blink.

The Core gets compiled.

I thought any files of the core, once compiled, would not need a recompile unless changed.

Yes, just as I said. @daveegreene was never able to complete a compilation, so the core was never compiled.

For the test I cleared the cache; maybe I should have mentioned that. So the core had to be recompiled. That way I could get the same (or similar) output as OP.

Thank you @sterretje . I have tried turning off the virus guard and downgrading the core to 1.8.3 but it is still the same. I have found that if I wait it does continue very slowly producing another line of output every 2-3 minutes. After half an hour it still hadn’t completed. Just to confirm to myself that I wasn’t doing something, I have loaded it to my laptop and it compiles first time in about 10sec. I guess it is interacting with something else on my PC other than the virus guard…

Took a bit of messing around but finally found the culprit so I’m posting it here in case anyone else gets the same problem. The very slow compiling of the core was caused by IBM Trusteer Rapport software, a cyber security program used by some banking apps. I wasn’t aware that it was still running as I no longer used it for banking, untill I saw it pop up in Task Manager while the IDE was trying to compile. Once removed the first compile of the core took seconds and now everything works ok. Thanks for trying to set me on the right path @sterretje
