"init terminating in do_boot" error message, when starting Yaws on Windows

Question

I would like to develop a web application in Erlang, so I installed Yaws 1.92 on Windows 7.

But when I try to start Yaws with both yaws and yaws -i I get this error message:

C:\Users\Jonas>yaws
{"init terminating in do_boot",{undef,[{yaws,start,[]},{init,start_it,1},{init,s
tart_em,1}]}}

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

C:\Users\Jonas>

Is there anything I'm missing? How can I solve this?

With the help from Steve's suggestion, I realised that my Erlang runtime was too old. I upgraded from R14B to R15B. Now Yaws starts, but it still prints some erros on startup:

C:\Users\Jonas>yaws

Any suggestion on why I get so many errors? and how to solve them?

Answer 1

The undef there is saying that the function yaws:start/0 isn't found. Seems like it may be a problem with the load path.

Try starting yaws like this:

yaws -i -erlarg "-boot start_sasl"

Hopefully that will give you more verbose output to help you track down the problem.
