link errors

[androclus]

I was previously able to compile for my hotdox keyboard a few weeks ago. Now cannot. I am on an OpenSUSE system, and just to be sure, I clone a fresh repo copy:

$ git clone --recurse-submodules https://github.com/qmk/qmk_firmware.git
$ cd qmk_firmware

Then I run

$ util/linux_install.sh

and this verifies that I have all the correct dependency packages installed on my OpenSUSE/Tumbleweed system.

But when I run

$ make hotdox:default:dfu

I get the following:

$ make hotdox:default:dfu
QMK Firmware 0.6.449
Making hotdox with keymap default and target dfu

Describe the Bug

Although all my dependencies (packages) are satisfied, and although I have changed no keymap files, and although it used to compile fine before, I am now getting linking errors.

None. Let me know if there is any additional information I can supply.

[fauxpark]

I can reproduce this on a fresh install of Tumbleweed.

Here is what avr-objdump -x reports for libatmega32u4.a:

In archive libatmega32u4.a:

eerd_block.o:     file format elf32-little
rw-r--r-- 0/0    696 Jan  1 10:00 1970 eerd_block.o
architecture: UNKNOWN!, flags 0x00000011:

...

Compare with the output on macOS:

In archive libatmega32u4.a:

eerd_block.o:     file format elf32-avr
rw-r--r-- 38007580/80    696 Jun  6 09:01 2019 eerd_block.o
architecture: avr:5, flags 0x00000011:

...

Similar results for the other files ld is complaining about.

Seems like something's up with the OpenSUSE package(s), if this build log is anything to go by: https://build.opensuse.org/package/live_build_log/CrossToolchain:avr/cross-avr-gcc8/openSUSE_Tumbleweed/x86_64

I'm having a linking error on Tumbleweed, too.

[drashna]

Was this still an issue?

[androclus]

It is not an issue for me (I am OP) but that is only because I sold my HotDox keyboard 3 years ago, a couple of months after posting this bug. It may or may not still have this problem.

If you need me to try to reload all the libraries and go through the compilation again, nonetheless, let me know. But maybe fauxpark or drashna are still up-to-date and can answer?

[fauxpark]

We dropped "support" for OpenSUSE a while back: #11408

If someone wants to get it working again, feel free.

[maiphi]

hotdox:default builds successfully on openSUSE Tumbleweed. I don't have this keyboard to test the firmware on, but the firmware I built for my Drop CTRL works fine. Needed to install the following dependencies: cross-arm-none-gcc12 cross-arm-none-newlib-devel cross-avr-gcc7 avrdude avr-libc dfu-programmer dfu-util.
