[zeromq-dev] zauth failure

Sun Jan 10 00:59:08 CET 2016

Hi Pieter,

Thanks for staying with me on this!

OK:

I built using the instructions from http://hintjens.com/blog:49 - this guy really knows his stuff ;-).

And yes, they included libsodium.

I wasn't running from Eclipse: I used Eclipse to try do debug it.  But it runs fine in the debugger.

The attached screen shot shows it running on the command line using a bash script that runs it over and over in a while loop.  I needed the script because the failure is intermittent (remember I said "mostly works").

I REALLY hate these kinds of problems.  If I enter printf statements, the problem goes away; if I try to use a debugger, the problem goes away.  It is down to deducing possible causes from a knowledge of the code.  Except I don't know much about the code!  I guess it is time to learn.  Ye Gods!!!

Put the attached very sophisticated script into your czmq directory and run for a while.  You might not see it: the time, the tide, and phase of the moon will be different.

Thanks for your patience.

Robert

"Running under Eclipse" :)

We normally build and test from the command line. You can run the zauth test by itself using: src/czmq_selftest -v -t zauth.

Which shows the same output as you're getting, except it continues with the CURVE tests (and your case seems to stop there).

How exactly did you build CZMQ? Are you using libsodium?
