sext doesn't build with rebar3: sext.beam not created

[benoitc]

To reproduce it, launch the following:

[sext] rebar3 compile
===> Verifying dependencies...
===> Compiling sext
[sext] ls _build/default/lib/sext/ebin
sext.app  tt_proto.beam

You can see that sext.beam doesn't exist

In verbose mode, you get the following log:

Removing edown from the build fixed the issue, so it may be just an issue with edown.

try with the rebar isnatlled locally (rebar3 local install) it should reproduce the issue On Wed, 4 May 2016 at 18:45, Ulf Wiger notifications@github.com wrote:

My rebar3 version:

uwpro:sext uwiger$ rebar3 --version
rebar 3.0.0+build.3380.reff7d88a5 on Erlang/OTP 18 Erts 7.3.1

But if this is rebar3 version-dependent, perhaps it's more of an issue with rebar3 than with sext?

[uwiger]

Ok, sorry, was doing several things at the same time.

Could you make a proper PR of it?

[benoitc]

what do you mean by proper PR ?
