Subject [jira] [Resolved] (COUCHDB-2045) Trace trap error while starting CouchDB
Date Tue, 04 Feb 2014 18:08:12 GMT

]

Robert Newson resolved COUCHDB-2045.
------------------------------------

    Resolution: Fixed

rebar.config.script used the same environment variables for icu, etc, and this seems to be
why this blew up. I've changed it so that only the libraries that each port needs are in the
environment.

> I ran into an error today in the 1843-feature-bigcouch branch, where running `./rel/dev1/bin/couchdb`
would result in the VM crashing with a trace trap error. I tracked this down to the couch_primary_sup
child spec for the `collation_driver` when calling `couch_drv:start_link()`, and more particularly,
I was able to reproduce this error in a standard Erlang shell by running the command: `erl_ddll:load("/tmp/bigcouch/rel/dev1/lib/couch-2f254d9/priv",
"couch_icu_driver").`
> After poking around with things, I ended up stumbling upon: http://openradar.appspot.com/7209349
(linked from http://erlang.org/pipermail/erlang-questions/2010-April/050563.html). I was able
to resolve the error by doing `export DYLD_INSERT_LIBRARIES=/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation`
in the shell prior to executing `./rel/dev1/bin/couchdb`.
> This seems like a logical addition to the flags set in `src/couch/rebar.config.script`,
but I'm not familiar with CoreFoundation, so I don't have a recommendation on the proper way
to do this across platforms.
