yes i did, but it gives me an error, either with "addf conv-float-s32.1
servo-thread" or "addf conv-float-s32 servo-thread" it says:
machinekit@beaglebone:~$ linuxcnc

Machinekit terminated with an error. You can find more information in the
log:
/home/machinekit/linuxcnc_debug.txt
and
/home/machinekit/linuxcnc_print.txt
as well as in the output of the shell command 'dmesg' and in the terminal
machinekit@beaglebone:~$
isnt it the function called "conv_float_s32.so"? if yes, i have that file
in the xenomai directory.
