Error

When I try to compile an ejabberd module I get this error:

$ cd ejabberd-modules/mod_admin_extra/trunk
$ ./build.sh
{"init terminating in do_boot",{undef,[{make,all,[]},{init,start_it,1},{init,start_em,1}]}}

Crash dump was written to: erl_crash.dump
init terminating in do_boot ()

What does that mean, how can I fix it, and how can I compile the module?

Solution

When it says:

{undef,[{make,all,[]}

it means it can't find the file make.beam which is included in Erlang/OTP. Depending in your operating system, the package that includes that file may be named erlang-nox (in older Debian), erlang-tools (in newer Debian), erlang-dev, ... Try to install packages named like this, and then retry to compile.

By the way, if later the compilation says something like this:

Warning: undefined callback function handle_event/3 (behaviour 'gen_fsm')

this just indicates that the developer didn't care to implement some functions he didn't need. Don't worry.
