The error suggests that the kernel module was compiled for another version, kernel or with another version of gcc (most likely one of the first two)
The kernel modules are not the same thing as firmware xml's and binaries and are not transferable.

so, I have to compile hm2_pci.c? and copy hm2_pci.ko to .../linuxcnc-dev/rtlib ?

Hi
I have no idea how you got to the stage where you get errors, whether you have installed a deb from the buildbot, built from sources or what
The directory you mention suggests possibly sources, but that is a guess
It should be part of a normal build along with hm2_7i43.ko and hm2_test.ko.
It is the firmware that is normally requires a seperate download
All the mesa files are in .../src/hal/drivers/mesa-hostmot2
The should have all built.
You will have to give a lot more info re version, branch and exactly what you are doing for me to assist any further
regards

So, this is the situation. I install ubuntu 12.04 from a 32bit iso downloaded on the ubuntu page. after that I followed this tutorial:
wiki.linuxcnc.org/cgi-bin/wiki.pl?LinuxCNC_On_Ubuntu_Precise
and used the masters-rt version
If I try to use a mesa configuration I get this error. (build-bot installation)
I have a copy of a run in place configuration(masters) from ubuntu 10, and it was compiled on ubuntu 12. if I try to run this I get this same error...
We will try to install again on ubuntu 12.

What do the last 20 lines of dmesg say after you get this error?
I have just run the plasma config and the error I am getting is because I do not have a Mesa card, so the driver just exits again, but it does load.

I'm just wondering is there some reason to try and use 12.04?

the error is that could not find the firmware, we manage to copy the firmware folders an it runs mesa plasma.
so we do try to do the same in the old ubuntu 12 partition, but got a diferent error, like in the first picture...
so now we will try to run the run in place configuration on the new partition and compile again, and at least, find where is the problem....
JT, its because the touch screen support, we can´t make work the lg flatron t1710 touchscreen that is on the machine...

Ok
That is progress at least.
So you CAN run the plasma config, once the firmware was installed.
I am pretty sure that the first error you had is because you tried copying across modules from a build on a different kernel and/or linuxcnc version
Building a RIP should just work, but check first that the gcc version is 4.6.x not 4.7.x
4.7 has a bug regards x86 code and will fail to build Linuxcnc with various errors
It should be, but it is easy to end up installing Ubuntu 12.11 instead of 12.04 and they started using it there
You will also probably get errors about missing includes in /usr/include/bits ./asm ./gnu ./sys etc
This is because they were moved to /usr/include/i386-linux-gnu/
Either symlink them back to the /usr/include folder or just copy them there, it is not much file size wise
