build error when building ibmpc_usb #752

Closed Gavus closed 1 year ago

Gavus commented 1 year ago

I have checkout 1820eff74 (master when writing) and I'm getting errors when trying to build ibmpc_usb. output.txt Basically says section .text overlaps section .keymap.

I can build other stuff like hhkb without any issues. avr-gcc version is 5.4.0.

It seems that firmware is bloated for some reason. If you don't edit any souce code try updating gcc to 7.3.0 or any newer than 5.4.0. (If you do it would be a cause.)

I had used 5.4.0 long time and it can be built somehow. Recent changes may cause with 5.4.0. But I have used 7.3.0 now and have no problem.

I tried to manually update avr-gcc on my Ubuntu setup but couldn't figure out out in a good way.

A fedora 37 docker environment solved my issues instead. It had a newer version of avr-gcc. Thanks!
