            Bug ID: 1379898
           Summary: rebar does not seem to build ejabberd, but does not

rebar output

Description of problem:
I've been working on debugging ejabberd's build, and I think it might be a
problem in rebar. It looks like rebar is checking the dependencies and exiting
with code 0 with seemingly no errors, without building anything.


Version-Release number of selected component (if applicable):
erlang-rebar-2.6.4-2.fc26.x86_64


How reproducible:
Every time


Steps to Reproduce:
1. Try to build ejabberd on Rawhide


Actual results:
The build fails, due to rebar not building any beam or app files.


Expected results:
Rebar should either build the files or print an error and return an exit code.


Additional info:
I am going to attach the full rebar output. I used my spec file to create a
failing build in ~/rpbbuild/BUILD/ejabberd-16.08 so that I would have all the
patches applied and dependencies installed. Then I ran the commands shown in
the attachment. Note that rebar exits after resolving the dependency
information, but does not seem to build any output, doesn't print errors, and
returns a 0 exit code.

The output does not show this, but earlier in this shell session I did run
these commands so that rebar would skip looking for the dependencies in the
deps/ folder:

REBAR_DEPS_PREFER_LIBS=TRUE
export REBAR_DEPS_PREFER_LIBS
IGNORE_MISSING_DEPS=TRUE
export IGNORE_MISSING_DEPS

--- Comment #1 from Randy Barlow <randy(a)electronsweatshop.com&gt; ---
Peter got ejabberd to build by avoiding their Makefile. I'm still not sure why
rebar wouldn't build as described here, but I'm happy to assume that it was an
environmental problem. Since I'm unblocked, I will close this for now.
