Hi all,
I tried to get the 'blog tutorial' to work with postgres and have
been unsuccessful getting it to work.
I followed the instructions on the link below and tried to get
the app to run but the compilation is failing.
http://translate.google.com/translate?u=http%3A%2F%2Fwww.cestari.info%2F2007%2F7%2F25%2Ferlyweb-et-postgres&hl=en&ie=UTF8&sl=fr&tl=en
As per the instructions mentioned in the link above, I have placed the
start.erl in the root directory of the application.
start.erl looks like this
---------------------------------
-module (start).
-export([boot/0, boot/1]).
-define(P, "/home/abhi/blog/").
boot() ->
boot(true).
boot(false) ->
compile();
boot(true) ->
pgsql_start(),
compile().
pgsql_start() ->
code:add_pathz(?P ++ "/ebin"),
application:start(psql),
erlydb:start(psql).
compile() ->
erlyweb:compile(?P, [{erlydb_driver, psql}]).
This is the error the app throws when I compile it in yaws REPL
command: start:boot().
error =>

Here are the details of the environment
--------------------------------------------------------
OS => sabayon linux
Erlang emulator version => 5.6.1
yaws version => 1.58
erlyweb => 0.7
I would really appreciate it if somebody can point me to resources or
help me configure erlyweb working with postgres and/or Mnesia
( Preferably both :-> ).
Thank You
Abhijith
