Hello, Thank you all for helping me on my last question. I have made the compiling as you have recommended: cd emc2/src ./configure -enable-run-in-place Make Sudo make install Is it normal to take almost 2 hours to compile the complete package on Duron 700MHz? There were also a lot of warnings during compiling. When the compiling was finished I have made: scripts/emc and the emc2 responded: Can't find bWidget 1.7 package. There is a debian bwidget package; install it with sudo apt-get install bwidget. This was a problem for me because I have no means to connect my computer which linux is instaled on to internet. So I have copied the complete BWidged-1.7.0 directory to /usr/lib/. When I start (scripts/emc) at the beginning was no problem. But when I made the selection from the menu the output was: localhost:/usr/local/emc2/emc2-testing# scripts/emc EMC2 - TESTING-2006-03-02 Machine configuration directory is '/usr/local/emc2/emc2-testing/configs/stepper/' Machine configuration file is 'stepper_mm.ini' Starting emc... insmod: error inserting '/lib/modules/2.6.12.6-rtai/kernel/adeos/adeos.ko': -1 File exists insmod: error inserting '/lib/modules/2.6.12.6-rtai/rtai/rtai_hal.ko': -1 File exists insmod: error inserting '/lib/modules/2.6.12.6-rtai/rtai/rtai_up.ko': -1 File exists insmod: error inserting '/lib/modules/2.6.12.6-rtai/rtai/rtai_fifos.ko': -1 File exists insmod: error inserting '/lib/modules/2.6.12.6-rtai/rtai/rtai_shm.ko': -1 File exists insmod: error inserting '/lib/modules/2.6.12.6-rtai/rtai/rtai_sem.ko': -1 File exists insmod: error inserting '/lib/modules/2.6.12.6-rtai/rtai/rtai_math.ko': -1 File exists insmod: can't read '/usr/local/emc2/emc2-testing/rtlib/rtapi.ko': No such file or directory insmod: can't read '/usr/local/emc2/emc2-testing/rtlib/hal_lib.ko': No such file or directory ERROR: Could not load 'rtapi' ERROR: Could not load 'hal_lib' Realtime system did not load Shutting down and cleaning up EMC...
