Upgrade 2.5 to 2.6 and to 2.7,nothing works

Hello Sebastian

I remember now , I did a "make install" in my 2.5 for intaller the new component biquad 9 mai 2014
some "files.so" and other files are from 9 mai 2014 !

www.linuxcnc.org/index.php/french/forum/...component-biquad-bug

I do not know what to do, I only linuxcnc in this PC (and windows xp empty in multiboot)

- You tell me where and how to delete the wrong files in a first time. ?
- I moved to new instal 2.5 lucid linuxcnc and upgrade to 2.6 2.7 ?
- I moved to new instal linuxcnc 2.6 or 2.7 package Debian best for the future?

Thank you for your help!

Ok, Thank you Sebastian !
