[SOLVED] Rebuilding master broke Mesa hm2_eth was created by rodw
I reinstalles Linixcnc master this morning to get a new version of gmocappy after Norbert fixed a bug I found.
I had to make it using sudo and this casued some permissions issues which I resolved.
Using run in place, Linuxcnc fails when loading hm2_eth as follows:
The bad conf file is to do with my USB wifi installation and id based on this link
wikidevi.com/wiki/ASUS_USB-N10_Nano
So my copy of LCNC is broken and I can't work out how to fix this. It worked before the upgrade.

I found thatRemoves the wifi driver and allows Linuxcnc to start
But it would be nice to have internet

I deleted the problematic .conf file and the problem went away and Wifi is back on again. I suspect Linux Mint supports my driver natively.

Sounds like you are having a bad day!
As far as linuxcnc is concerned all the "program" and files therein should be only in your RIP. Have you tried to do a new git pull with linuxcnc-dev1 or another name and try another rip? The rip is self contained and should not have a bearing on your issue.
The wifi driver problem is interesting.. Are you having a problem with linux mint loading the wrong driver or two drivers at the same time?

cncnoob, thanks your advice on the other thread helped me solve this. I took ownership of all my home directory content from root, did a make clean and another make and it is all working again. Now only if I could get the last 5 hours of my life back!
I could not understand why rebuilding lcnc broke internal stuff. I have no idea how root got ownership in the first place.

My thought would be that since the build process is in your home folder, the process generated the files with root ownership therefore taking permissions from you and making them root.
Yeah, sudo in root folder has given me fits before... I have done clean installs because I messed up building software and it was much easier to just start again. Glad you go it going!

This can cause endless pain and suffering
I dont think there is ever a reason to build a RIP version of LinuxCNC as root
(other than the make setuid part)

It did that!
Yes, I don't understand why root had stolen my permissions which prevented me from running make in the first place. Anyway, its fixed now!

For some silly reason hm2_eth thinks it is a network administer, and plays with ipv6 settings and iptables, in a very non-robust manner.
Why?
Why?
