Modbus Examples?

Hi ArcEye.

The libgl1-mesa-dev was missing , I installed it and then run again ./configure --enable-run-in-place this is the result :

Sorry ArcEye but I have really problems handling Linux and this kind of stuffs .
So do not blame me .... I need your help ....
I can see TCL library not found , but what it means .... I don't know.

sudo apt-get install tcl8.4 tk8.4

I think it needs 8.4 rather than 8.5

( Possibly tcl8.4-dev tk8.4-dev if you still get problems - I installed it all so long ago it is hard to remember)

Hi.

I should have already installed the 8.4 version because when I make the command

sudo apt-get install tcl8.4 tk8.4

I got the message that the tcl8.4 and tk8.4 are already the most recent version .

bigalex

Then try tcl8.4-dev tk8.4-dev

Hi.
One step forward ......
I made

sudo apt-get install tcl8.4-dev tk8.4-dev

Now I have this error message

It's just telling you that you need to install libreadline

Try this and you will have everything you should need, some you already have now

sudo apt-get install cvs build-essential fakeroot debhelper libpth-dev libgtk2.0-dev kernel-wedge tcl8.4-dev tk8.4-dev bwidget python2.5-dev python-tk python-dev libglu1-mesa-dev libgtk2.0-dev libgnomeprintui2.2-dev libncurses5-dev libxaw7-dev gettext libreadline5-dev lyx texlive-extra-utils imagemagick texinfo groff qt3-dev-tools

Hi.

I tried your advice but I get a problem with Python2.5 .
So I've installed libreadline5-dev and I've removed tcl8.4-dev tk8.4-dev because was needed tcl8.5-dev tk8.5-dev.
Now I have :

checking for Xmu headers... checking X11/Xmu/Xmu.h usability... no
checking X11/Xmu/Xmu.h presence... no
checking for X11/Xmu/Xmu.h... no
configure: error: Required Xmu header missing. Install it, or specify --disable-python to skip the parts of LinuxCNC that depend on Python

Do I have to install libxmu ?

bigalex

I tried your advice but I get a problem with Python2.5 .

The trouble you had was that it has been deprecated, the error message tells you what to do
apt-get install python-old-doctools

Hi ArcEye.
I did as you mentioned:

apt-get install python-old-doctools

I run again:

./configure --enable-run-in-place

and I have still this :

checking for Xmu headers... checking X11/Xmu/Xmu.h usability... no
checking X11/Xmu/Xmu.h presence... no
checking for X11/Xmu/Xmu.h... no
configure: error: Required Xmu header missing. Install it, or specify --disable-python to skip the parts of LinuxCNC that depend on Python

So if it is too complicated to get it running maybe I have to stop this .
I don't want to profit by your courtesy.

One question .... I understood that mb2hal is a hal component isn't it ?
Why it is not possible install it in a simplest way ?
This question is only to understand .
I don't want to criticize anybody.

bigalex

configure: error: Required Xmu header missing. Install it, or specify --disable-python to skip the parts of LinuxCNC that depend on Python

The error is just telling you what is missing from your system, you just need to install it

sudo apt-get install libxmu-headers

One question .... I understood that mb2hal is a hal component isn't it ?
Why it is not possible install it in a simplest way ?

mb2hal is a component only available in 2.6, I assume it either uses features not available in 2.5 or it is considered so experimental that it is not in a mainstream distribution.
Once you have compiled Linuxcnc you will have built mb2hal also, so keep at it
