currently glitch uses erlang otp 24 and i need to use erlang otp 26+ because the way i am building my project requires it

does it require a recent glibc?

3

NPTL glibc is strongly preferred

its prefered but not required they use it for optimization

requirement on linux

https://www.erlang.org/doc/system/install.html#building

oh ok yeah, Glitch’s containers support pthreads. I think that’s what NPTL refers to.

yeah apperntly its not possible to install that version of Erlang on ubuntu 16 or 18

8

does it depend on something that’s in other versions of Ubuntu?

I’ll try building a copy of this from nixpkgs

this is nixpkgs’s beam_nodocs.interpreters.erlang_27

I manged to get it working ! i am using Gleam language and it compiles to Erlang then i run the Erlang server using your template above and it works smoothly thx

i don’t need gleam to be installed because the folder is 30mb but when i compile it to Erlang it becomes 3mb which is nice for glitch maybe i will need to setup github action to build and upload the built project to glitch :heart:

I have made a github action using few glitch guides
i will summerize it and change what i did different

Go to the Glitch terminal
Run git config receive.denyCurrentBranch ignore

create a githook in the terminal using your favorite text editor. I used nano so nano .git/hooks/post-receive
Put this bash script into your hook:

#!/bin/bash
unset GIT_INDEX_FILE
git --work-tree=/app  --git-dir=/app/.git checkout -f

Give your hook execution permission chmod +x .git/hooks/post-receive

i first build the project then i commit the output to a new branch then i sync that branch with glitch

Github actions file

oh yeah, I remember reading about this hook thing.

you might need to run glitch’s refresh command too, so that it restarts your app process

i didn’t need to do that just updating the code and running the github actions was enough for the running server to change
