Using Twoorl With a different MySQL port

[Steven Lohrenz]

I'm new to Erlang and I have setup and run successfully the 'music'
introduction application using and instance of MySQL on port 3305.

I was trying to get Twoorl to work on my Vista machine. I have added: -
define(PORT, 3305). to twoorl_app.hrl and compiled it. I have the
twoorl database setup and the rest of the definitions in
twoorl_app.hrl set to the correct values.

When I am in yaws and run: twoorl:start(). I get the following
message:

twoorl:109 "creating schema"
twoorl:112 "schema already exists"
twoorl:135 {"waiting for tables",[session]}

=ERROR REPORT==== 30-Mar-2009::11:28:58 ===
Error in process <0.129.0> with exit value: {undef,[{twoorl_util,log,
[mysql_recv,108,error,#Fun<mysql_recv.1.31365121>]},{mysql_recv,init,
4}]}

** exception exit: {noproc,{gen_server,call,
[mysql_dispatcher,get_logfun]}}
in function gen_server:call/2
in call from mysql:connect/9
in call from lists:foreach/2
in call from twoorl:start/0

Does anyone have any ideas on how to fix this or how to setup twoorl
with a different database port?

Thanks,
Steve

Hi Steven,

Welcome to the wonderful world of erlang! :)

This error:

Error in process <0.129.0> with exit value: {undef,[{twoorl_util,log,
[mysql_recv,108,error,#Fun<

mysql_recv.1.31365121>]},{mysql_recv,init,
4}]}

Should read as: the log function of the twoorl_util module is not defined.
In this case this happens because the twoorl_util module was not compiled when you ran make.

You can fix the problem by editing the file Emakefile and adding the line:
{"src/twoorl_util.erl", [{outdir, "./ebin"}]}.
and then running make again.

I understood from the README.txt that I downloaded with twoorl that
all I needed to do was setup the database, modify twoorl_app.hrl,
compile twoorl.erl, and then run twoorl:start(). in yaws - and the
twoorl:start() was going to compile the rest of the app. I see there
are compile functions in the twoorl module and the last line of
twoorl:start calls one of them. I'll try to run the make file first,
then.

Cheers,
Steve
