[erlang-questions] Erlang/OTP R14B02 generating documentation from source problem

[Kazuhiro Ogura]

Hi,

I had the same error, and after some struggles,
finally I changed the shebang line of
lib/erl_docgen/priv/bin/xref_mod_app.escript
to the absolute path to escript, and it worked.

-#!/usr/bin/env escript
+#!/usr/local/bin/escript

I don't know why it worked,
so I can't tell whether this works for you or not.

Sure I have xmlerl-x.y.z in the lib/ dir, and I can load xmerl in a
normal erlang shell.
Also what's strange is that when I manually execute the command,
(which fails complaining about exception about xmerl:export_simple/2
in the make process),
it succeeds without any errors.

(May be some envvar passed to script is doing something wrong?)

> It seems to me like xmerl is not in the erlang install which is in your path. Check that xmerl-x.y.z is in the lib/ dir of the erlang you have in your path. or alternatively that you can load the xmerl module in a normal erlang shell.
