mc_ does 4.3 only compile on Erlang 19 or will it work on later?

lvlinux: i think i've seen 22 used

not sure that 23 would work, there are breaking changes that either kazoo or a 3rd party dep break on

forget which

I installed OTP25 (default from erlang solutions) on a Debian 10 box, and it failed in: src/app_utils.erl: error in parse transform 'lager_transform':

Ah ok so i should go back at least to 22

i'll have to figure out how to revert lol

Do you recommend that I do 22 or earlier like 19?

lvlinux: 19.3 is "recommended" but i think 21 for sure still works, and 22 may work

i use kerl to manage OTP installations locally

rather than packages

but up to you

k thx

mc_ I can compile in one version like 19/20/21, on say, debian, and then move an application ebin file to a centos system running from official repo packages, right? Or do I have to compile on a matching system?

in general, OTP is compat for 2 major versions

but we don't really test that too far

so ideally you run on a VM compiled for the same BEAM version

I installed v22.2.7 and it failed build at a different place (building cowboy), so I guess I'll try kerl and do v19.

src/cowboy_http.erl:388: variable '_Stacktrace' is unbound

Hmm...
