Incidentally, I initally created the release on a 32 bit dev machine and deployed out to a 64 bit stage machine which of course did not work well at all - I got cryptic libcrypto errors. I'm trying to be "good" and migrate an scp ebin/* + init.d system to proper erlang release handling, and this post has been by far the most helpful thing on the entire web.

Without sys.config bin/start won't run. 2. I'm using target_system module that automates all the steps you list here: http://erlang.org/doc/system_principles/create_target.html#3 but I had to change the permissions of several files in the bin directory to executable. 3. In my case the path created by target_system was relative and it might also cause problems, so I changed it to absolute path in several places.Thanks I’ve found several problems:

The only thing I didn't do is set emulator flags because I'm not sure what it means.Thanks Jacob, I’ve repeated all the steps from scratch but still getting:

Make sure all the paths and commands exist. Could be that bin/start is referencing another command in bin/ that isn't there, such as start_erl or run_erl. Or maybe bin/start is working fine, but bin/to_erl is looking in the wrong directory.And you're right, I should add a sentence in step 8 about copying bin/to_erl.

I’m following all the steps but when trying:
bin/start
bin/to_erl
I’m getting: No running Erlang on pipe /tmp/erlang.pipe.

Any idea what I’m doing wrong?

Thanks

I'll look into it, thanks for the heads up. Could be something new in erts-5.7.2, which I hadn’t tested with. I’ll look into it, thanks for the heads up.

Thanks. Hi.

Most Erlang/OTP tutorials neglect the critical deployment step, so this post is quite valuable. Thanks for summarizing the process!
