Build fault

Hello Guys,

I was making some updates to one of my builds and got this fault when trying to run linux,

Any thoughts?

Thanks Rick

Disregard,

I started over from the top with the reset/hard for master and it started fine this time.


Thanks

Rick

Ok, I must be doing something wrong, I was having issues on my 10" machine with it reading tools, so I did " sudo make clean" in my src directory, then went through with re-compiling. After I ran the ". ./scripts/rip-environment" then "linuxcnc" and picked my configuration, and here is the result.

Any thoughts, or suggestions

Hi

Hello Arceye,

Here is the printout, and tell me if I'm wrong but, the two columns say root next to the affected files ( which were highlighted red when I did ls -l, so convenient) means that I am not the owner. So those I need to change, and trying not to be big a pain in the #^%, could you give me an example?

Hi

Assuming your user and group are rick

sudo chown -R rick:rick /home/rick

Then from ../src make setuid (or probably sudo make setuid)

It all comes about building in your home directory using sudo, which does the build with the owner being root, not you

regards

This definetly gets dis-couraging after a while, mainly because of my lack of knowledge on the programming side.

Here is what I did, and its output.

srt@Cinci:~$ sudo chown -R srt:srt /home/srt
[sudo] password for srt:
chown: cannot access `/home/srt/.gvfs': Permission denied
srt@Cinci:~$

Do a ls -l on that directory, who is shown as the owner of that hidden file? (/home/srt/.gvfs)

dr-x

2 srt srt 0 2013-06-11 12:39 .gvfs


I notice the 2 and the 0 being different than the rest of the files, does that matter?

Hi

Sorry for delay, Atlantic drift.

The output should be
permissions | number of links | owner | group | size | creation / modification date | time | size

What I have not found a good explanation for is the number of links.

It is analogous to but does not match, the number of subdirectories when the object is a directory and does not seem to match the number of symlinks when the object is a file.

Did the rest of the files change ownership and allow you to run them?

regards
