Just so some context is available here, you are asking for the Kodi team to maintain binary addons compatible with a
wide range of different Linux kernel and libc combinations, dating back over half a decade:
- Frodo, 29 January 2013
- Gotham, 4 May 2014
- Helix, 23 December 2014
- Isengard, 21 July 2015
I feel that is wildly unrealistic. For comparison, here's the timetable of currently supported Linux LTS kernel versions:
- 3.2, 4 January 2012, EOL May 2018
- 3.16, 3 August 2014, EOL October 2014, re-introduced until April 2020
- 4.1, 22 June 2015, EOL May 2018
- 4.4, 20 January 2016, EOL February 2022
- 4.9, 20 December 2016, EOL January 2019
- 4.14, 12 November 2017, EOL January 2020
As you can see, the only Linux kernel that was around Frodo was released was 3.2, which only has support until May of this year. (Even that is barely there, save for RHEL type backports ...) Same for Gotham. Helix was released after LTS kernels 3.16 and 3.18, both of which are no longer supported. Isengard's newest kernel release was 4.1, which is also EOLed for May of this year.
Considering the large number of kernel changes that have happened since those releases, in addition to the numerous updates to other support libraries required by Kodi, it is wholly unrealistic to expect support for software that old. If your hardware is unable to run a Linux kernel and Kodi version that is currently supported, you either should look into updating your hardware, or seek a commercial suppport solution that will work with your particular hardware requirements.
