@DPFlex ... from 2.8 I'm unable to use halcompile .... AndyPugh suggest to use a rip install ..... you download on Lcnc_292_wharehouse ..... search on these new folder scarakins.c and change it with modify version .... than run process for make .... when obtain compilation file on rtai folder inside Lcnc_292_wharehouse folder of rip install, use sudo command for root permission, search for original one scarakins.c of your installation (if not use a rip install) and cancel these, copy with root permission your scarakins.c compiled from Lcnc_292_wharehouse folder to system folder. Reboot ... all done.
Use these tryk for all modifications. Or learn you about customkins.c (never looses these time really) .....
If you have a rip istall .... use the same trick, but change modify scarakins.c from your "compiled Lcnc_292_wharehouse folder" to your preferred rip install .... reboot and voilà.
