Modbus Examples?

Using Classicladder I was finally able to control one drive.
I think I am still going to try to work up a configuration for Classicladder, and try to see how many drives I can make run with it.

If CL is limited to only 16 modbus communication instances then I will probably only be able to run half my drives with it and I will have to look to some other solution. (probably mb2hal).

Once I am done experimenting with CL I will try to post what I've learned somewhere, probably in the wiki.

Hi people.
I'm interested at mb2hal component too.
I've found the files into the git here .
But how to install the component into LCNC ?

Sorry but your going to have to walk a noob like me through this.
trying to follow what is in the wiki here
wiki.linuxcnc.org/cgi-bin/wiki.pl?ModbusToHal
I can't even get past the 1st step.
I open a terminal and type in the command and get thisI am sure I'm leaving out some simple but very important steps that are not mentioned in the wiki.

You have to build it.
It is not a Ubuntu package

www.libmodbus.org/download/

(EDIT: or do git clone git://github.com/stephane/libmodbus)

Then just ./configure && make && make install

Builds fine on my system, albeit I have every development library known to man on here, so you may get some dependencies crop up from configure

Where should I save it?

(Told you, I don't know what I'm doing)

Either go to /usr/src and use the git pull line
or
download the zip (easier) and extract to /usr/src/libmodbus-3.0.3

Then cd /usr/src/libmodbus-3.0.3
./configure && make && make install

Thanks,

that did something, but are these errors of any concern?

make all-recursive
make[1]: Entering directory `/usr/src/libmodbus-3.0.3'
Making all in src
make[2]: Entering directory `/usr/src/libmodbus-3.0.3/src'
CC modbus.lo

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/src/libmodbus-3.0.3'

OK step 2 seemed to go ok,

step 3, I am getting stuck when I type make, it says "No such file or directory"
