[Erlangweb-users] getting erlang-web running on ubuntu-server

[gqwu <gq...@ya...>]

Hi everyone. I'm trying to follow the tutorial.pdf to get erlang-web running in ubuntu-server.

I used a brand new ubuntu-server 8.10 VM, did apt-get erlang & yaws, and opened up port 8080 in iptables. Erlang shell works and ubuntu's yaws localhost:8080 default successful page shows up.

I downloaded and extracted erlangweb-1.1.1.tar.gz. I run 'erl -make' and a bunch of 'Recompile: lib/...' msgs fly by.

Then I create an empty directory and run 
erlangweb-1.1.1/bin/start.erl and see a bunch of 'Element created:...'.

Next I try running 'bin/start interactive' but get the following error:
--------------------
Erlang (BEAM) emulator version 5.6.3 [source] [async-threads:0] [kernel-poll:false]

{"init terminating in do_boot",{undef,[{e_mod_yaws,start,[]},{init,start_it,1},{init,start_em,1}]}}

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

I also tried making en Emakefile in the project directory with:

{"lib/<my_app_name>/src/*",[{outdir, "lib/<my_app_name>/ebin"},
{i, "lib/<my_app_name>/include"}, debug_info, strict_record_tests, netload]}.

and then compile it with 'erl -make' or 'erl'&'make:all()' but nothing happens.

Anyone know what I'm doing wrong? I'm guessing it has something to do with yaws.

Thanks!

 Here is what I did per INSTALL file (on ubuntu 8.04) and it worked

$ cd /to/where/I/want/to/install/erlangweb-1.1.1
$ tar -xzf erlangweb-1.1.1.tar.gz
$ cd erlangweb-1.1.1
$ erl -make
$ bin/start.erl
$ bin/start interactive

and then http://localhost:8080 returns page

Your error looks unrelated but do make sure other yaws instance is not
running on port 8080 when doing the 'bin/start interactive' above

[Erlangweb-users] Odp: getting erlang-web running on ubuntu-server

[Michal P. <mic...@er...>]

Hi,
It seems to be a known bug (discovered by Paul Bernard) with building the project only from the current working directory.
The workaround (for now) is to run all the bin/start commands from the directory where you have the sources. 

In your case you should download the Erlang Web tarball and then:
tar -xzf erlangweb-1.1.1.tar.gz
cd erlangweb-1.1.1
erl -make
bin/start.erl
bin/start interactive

The error you are getting has nothing to do with Yaws ports - "bin/start interactive" command simply calls
erl -pa lib/*/ebin -s e_mod_yaws [other options], so when you are outside the root directory of your application, the beam files are not in your path anymore (the command should look like: erl -pa erlangweb-1.1.1/lib/*/ebin -s e_mod_yaws [other options]). 
bin/start script will be corrected shortly.

Best regards,
Michal Ptaszek

There is an easy workaround so you can start with an empty directory.
I'm quoting from memory and not tested the following exactly so watch
for typos and oversights on my part.  I've done it a few times now.  A
patch is included below:

mkdir <originaldir>
tar -xzf erlangweb-1.1.1.tar.gz
cd erlangweb-1.1.1
patch -p 1 <patchfile
erl -make

mkdir <otherdir>
cd <otherdir>
export ERL_LIBS=<originaldir>/erlangweb-1.1.1/lib

<originaldir>/erlangweb-1.1.1/bin/start.erl
cp -a <originaldir>/erlangweb-1.1.1/lib/yaws-1.73/include <otherdir>/lib/yaws-1.73

Now it *should* start.  I've not personally used the "bin/start
interactive" version.  I just "bin/start;sleep 2;bin/start connect", I
have no reason other than habit.

Patch:

I have to do the first one because my erlang has been compiled with SMP
disabled.  The second one fixes a typo.  The script should almost
certainly copy yaws' include directory.  I did so and then backed off
and lost it.  I just do it by hand for now.
