Welcome to LinuxCNC.org

Hello,
When you start EMC2 I find the following error:
"insmod: error Inserting '/ home/mipretec/Documents/emc2-dev-rtai/rtlib/hostmot2.ko': -1 Unknown symbol in module"
I tried to compile hostmot2 but with a curious result (see below) if anyone has an idea, thank you in advance.

I don't think you can compile Hostmot2 with "comp". I always do a full "make" when compiling/developing Hostmot2 components.

Why are you trying to compile Hostmot2? It should already be there as part of your installation.

Assuming you do want to compile, then you need the sequence
make clean
./autogen.sh
./configure
make
sudo make setuid

Thank !
sorry for my English, I know that "Google translate English"
tool "comp" compiles French.
By cons and it is the best I have executed the instructions (make,. / Configure, ..) and is now recognized hostmot2. With some other fixes and moving files it should work.

Michel

So, is it all working for you now?

This almost works, we still have a few problems. This works in simulation mode but not yet with the PCI card.
Thank and see you soon for sure.
