Release/Compilation issue in linux

[sescobb27]

Hi, i was trying to use jiffy with the example you provide in the readme but i had some issues with it, first of all, it compiles but it didn't include it in the release, so when i run rebar3 shell it worked but it didn't with

$ reba3 release
$ _build/default/rel/ec_api/bin/ec_api console

running jiffy:decode(<<"{\"foo\": \"bar\"}">>). throws ** exception error: undefined function jiffy:decode/1
there is a related discussion going on in davisp/jiffy#118 about this because it seems to work in mac davisp/jiffy#118 (comment) but not in linux, so i think the issue should go here. thanks

That error message is saying you didn't include jiffy in your release. This isn't a port compiler bug. You must depend on jiffy in your .app.src file or list it in the list of application to include in the release in the relx config entry.

thanks for your fast reply,
i'm just learning erlang but i thing jiffy isn't an otp application so i don't think it should go there, i tried with https://github.com/sile/jsone and worked perfectly without adding it to my .app.src, also it seems to work on mac but don't on linux as shown here that's why i thought the issue should be here.
thanks.

jiffy is an otp application.

this is what i get adding it to my .app.src

[sescobb27]

nothing

What's the status here?

[sescobb27]

we are using jsone right now, I think we can close it given that it seems anyone has the same issue

[ogolosovskiy]

I see the same problem
