[mihini-dev] Getting Started with Mihini

[mnerys@xxxxxxxxxx]

I got a fresh install of Raspbian
"wheezy" and tried to
put Mihini on it.

I followed:
http://wiki.eclipse.org/Mihini/Run_Mihini_on_an_Open_Hardware_platform

On Step 1, I initially took the first
option:
http://wiki.eclipse.org/Mihini/Build_Mihini

There, I got an error with modbus (please
see attached log).


Since modbus was an optional step, I
continued and the build ended up fine.

Later on, I started Mihini on my device
and verified I could connect to it using:
telnet localhost 2000
(BTW: I had to use the ldd trick presented
on the wiki)

Then, I tried to Export a Lua Project
from LDT and it failed with a connection refused error. I tried to do a
telnet from my workstation to Mihini and I could not connect either.

I could do an ssh to the Raspberry Pi
(I was looking for issues with firewall configuration) and I noticed that
a telnet on the Pi works only with localhost. If the Raspberry Pi's IP
is used, connection fails.

I decided to move to the 3rd option
(of Step 1):
http://wiki.eclipse.org/Mihini/Install_Mihini

This time I could use telnet from my
workstation and use LDT to export a Lua Project to the Raspberry Pi.

The problem that I am facing now is
that I am trying to use the sample code on Step 4:
local log
  = require
"log"
local sched
= require
"sched"
local function
main()
    log("GENERAL",
"INFO",
"My first Mihini app is alive :)")
end
 
sched.run(main)
sched.loop()

However, the syslog does not show the
message above. It seemed like the app was failing to run. I am not sure
if this would work, but I tried to run:
cd /opt/mihini/apps/test
./run 

And no module from Mihini is being found.
If I comment the 'log' module out, then I get an error with 'sched'.

lua: main.lua:1: module 'log' not found:
        no

It seems I am out of luck with Mihini.
Could you please advise?
