Describe the bug

I try to build latest stable release version 2.2.4 in a supported environment following OpenTX-2.2-Linux-Build-Instructions

This is not possible.

To Reproduce

I installed docker on my opensuse leap 15.1 system (any other source system will do)

sudo zypper in docker
sudo systemctl start docker

Then I downloaded the dockerfile and tried to build the docker image.

mkdir opentx
cd opentx
wget https://github.com/opentx/opentx/raw/2.2/radio/util/Dockerfile
docker build -t opentx

This fails after some time

Expected behavior

Image build succeeds.

I already checked: the gcc-avr_4.7.2-2_amd64.deb does not exist (anymore) at http://ftp.de.debian.org/debian/pool/main/g/gcc-avr.
Oldest available version is the 5 year old version 4.8.1.
Since I don't know debian, I don't know where to find older versions.
Since this is my first contact with opentx and the link above warns about inconsistent behavior I hesitate to use other gcc-avr versions.
Do you have a workaround? This should then probably be documented at the link above and dockerfile adapted.

Thank you.

You should be able to remove all the AVR stuff in lines 16-20 from the Dockerfile since we dropped support for AVR stuff in 2.2 anyway. We removed it in 2.3. https://github.com/opentx/opentx/blob/2.3/radio/util/Dockerfile

found the missing files. Hope it helps. It built fine for me now. Thanks @kilrah

[kilrah]

Did you try removing them as I suggested? If that works it is a better fix.

[joba-1]

I didn't go that route first because I didn't want to remove a feature from a stable version, even if that feature is declared not supported.
And I have no means of actually testing the firmware, I wouldn't even know what to look for.

But I did test building it right now: as expected, this works for me too: "[100%] Built target firmware" :)

Thanks!
