[crash report] bin/kraken run

[benjamn]

Big caveat: I just installed Erlang R16B, and while the shell seems to work, I've never used it for anything real, so my Erlang installation might be the problem.

Here's the output from bin/kraken run:

~/src/kraken % bin/kraken run

[krisr]

Thanks for the bug report. I'll see if I can reproduce and get back to you shortly.

[krisr]

Hey Benjamn, that happens to be the same error you would get if you forgot to build the project first. Did you run "./rebar get-deps compile" first?

[benjamn]

@krisr, yep I did, although there were some warnings at the end:

[krisr]

Looks like it failed to build a dependency because erlang R16B no longer supports parameterized modules and did get to compile kraken as a result. It's unfortunate that log4erl depends on mochiweb since we are not using it at all. I'll see what I can do after getting the latest erlang build on my machine. In the meantime, you could try using an older version of erlang. I know R15B02 works.

[benjamn]

Got it, thanks. I'll leave it to you to close/edit this issue to reflect whatever you decide to do.

[krisr]

There is an update to mochiweb for this already, I'll sort out the dependencies in log4erl and push a fix shortly.

[manjuraj]

@krisr I encountered the same issue

[krisr]

@manjuraj Thanks for the report. I have some time this evening so I'm going to work on getting log4erl building with erlang R16B. I'll keep you posted.

[krisr]

@manjuraj, @benjamn, I forked log4erl and made it depend on a more recent version of mochiweb which compiles successfully with later version of erlang. You may need to clean out your kraken/deps/* directories to get things in a working state after you pull the change. Let me know if it works for you now and I'll go ahead and close this issue.

[benjamn]

@krisr works for me after updating, thanks!

[manjuraj]

@krisr works for me too

[lloydchang]

Hello @krisr @benjamn @manjuraj, I'm also confirming that current git HEAD 698fc66 runs successfully using Erlang R16B. Thank you.
