1. Now I have internet access for my computer. And I installed software as described in the emc wiki:
http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#On_Ubuntu_with_EMC2_package_already_installed But everytime when I build emc2 realtime and simulator, there are errors which are different everytime. The following is an error. Could you give a method to solve it? libinch...@libincheng-desktop:~$ cd emc2-trunk/src libinch...@libincheng-desktop:~/emc2-trunk/src$ ./configure --enable-run-in-place checking installation prefix... /usr/local checking for RT dir...

I am thinking if I have not configured apt correctly.Then how to configured it correctly? Thank you for your help! Regards!
