Compiler broken for avrtiny chips (eg ATtiny10) #568

Closed WestfW closed 2 months ago

WestfW commented 2 months ago

For some reason, the avr-gcc compiler included with recent avr board installs fails to compile code for ATtiny10, getting messages about missing and/or incompatible libraries. The libraries do seem to be there; I'm not sure what is wrong with them. This seems to have happened with the transition to (ARDUINO-compiled?) avr-gcc v7.3 from v5.4; the last version where it works in Arduino 1.8.9

Note that the 7.3.x compiler downloaded from Microchip works properly... (and note that this is a bare compile. No IDE involved.) Theses file DO exist in their expected places. I don't have deep enough knowlege of gcc builds to figure out why they aren't being found, or are being rejected as incompatible.

Here's a log with the verbose option enabled...

Hi @WestfW. Thanks for taking the time to submit an issue.

I see we have another report about this at https://github.com/arduino/toolchain-avr/issues/65.

It is best to have only a single issue per subject so we can consolidate all relevant discussion to one place, so I'll go ahead and close this in favor of the other.

If you end up with additional information to share, feel free to comment in the other thread.
