Compiler error building with rebar. about erlang-jose

[potatosalad]

@peterlong Do you know what version of OTP you are using to build everything?

[peterlong]

Hi @potatosalad, I downloaded 3 versions, otp_win64_17.5, otp_win64_19.2 and otp_win64_R16B03-1. I am about 90% sure I am using v17.5. It installed to c:\Program Files\erl6.4

My goal was to use the same version of Erlang as CouchDB 2.0. It has a erts-6.4 sub-folder, so I assume that matches with erl6.4.

Here is a log of how I tried to do this build.

Optional callbacks were added in OTP 18 and while I have rebar detect OTP 17 and compile the code differently, it sounds like it's not working correctly. Have you tried building with OTP 18 or 19?

[mkazlauskas]

CouchDB 2.0 uses OTP 17, which means we're limited to this. Any chance of making it OTP 17 compatible?

[potatosalad]

@mkazlauskas Are you having a similar build issue to the one described above?

[mkazlauskas]

I am. I did disable errors as warnings in my fork so it built successfully. Not sure if it'll work thoughOn Jul 12, 2017 19:55, Andrew Bennett <[email protected]> wrote:@mkazlauskas Are you having a similar build issue to the one described above? —You are receiving this because you were mentioned.Reply to this email directly, view it on GitHub, or mute the thread.

I'll try to look into why it's failing on OTP 17 and see if I can get things working again.

[mkazlauskas]

Thanks. It should be OTP 17.3 since I'm using https://hub.docker.com/r/klaemo/couchdb/

Also, running on Linux.

Cleaning up older/neglected issues 😖

Hopefully this is fixed now, please reopen if you're still having issues.
