Ignoring the username, can anyone help out with this last failure? Trying to install linux cnc on 12.04 for g-code generation and educational purposes for me outside the shop, and Ican't get it to make. Any pointers would be awesome, thanks. below is the error I get

You don't have the right permissions in either / or directories and files
You have an extrordinarily convoluted path, would be easier to copy linuxcnc to /home/butts/src (you will have to make src)
The run sudo chown -R butts:butts /home/butts/* which will ensure that everything in your home folder belongs to you
Then build from the start again
Unless the linuxcnc tarball was downloaded as your user and the directory you try to build it in was created by / owned by your user, you will always hit problems

yes those were the steps followed. I tried repeating the last 4 steps w/ a sudo but it didn't help. Yes my pth is convoluted, but it is the way my system is lain out for now, my OS is on a SSD and this is a second drive, as linuxCNC doesn't warrent space on the SSD at home here.

At what point exactly did the process fail and what was the message? I suspect your missing/skipping something...

Hi
I have pulled the master with git and built a simulator as root and as a user, without any problems.
The only way I can get similar problems with access and permissions, is as I described, downloading the git as root and trying to build it as a user in a directory not belonging to me.
But even then, it will fail at ./autogen.sh not make
chowning the whole user directory and its children solves the problem
Something has just occured to me.
What is this second disk formatted as?
If it is formatted as windoze (fat16 or fat32) you cannot create symlinks on a windoze file system.
regards

it appears to be a big permissions issue, something about the way I am mounting that drive i suspect. it is a linux partition, I have many a happy sym link coming from that drive, hwoever it seems to belong to root (although my group seems to have full permissions, not sure waht is up there) and I can NOT chmod and make it mine, permission denied even to root! I also can't chagne it thru nautilus using gksudo, so I abandoned all hope ye who chowns here, and did it on my SSD and it went better.
however the command to lauch linuxcnc after adding it to my path is confusing, is the . and whitespace correct? it does not work for me, so I navigated to ./scripts/ and tried to launch it with "linuxcnc" and I get a no command response
any ideas on that last one?

on a whim I navigated to the scripts folder with nautilus, and simply double clickling on linuxcnc launches it, so why can't i launch from terminal?

The dot sets the environment for that terminal session only.
There needs to be a space between it and the next dot.
Without the environment set to the build dir, it will look in the normal PATH for
executables and LIBPATH for libraries
Using this method you could have a system wide install of 2.5.3 and 10 different RIP builds and they will never conflict.
(in fact that describes one of my partitions)

RIP? is that like WIP?
also I found the issue, the last two steps arebut I dont think that will work, it either needs to be
or
whichever makes more sense from a usage point of view, I would think the former but I am not sure. Thanks for the help guys I seem to be up and running. Now when I launch a demo config, and ask it to create a short cut it will do that, however it does not create a config folder, which IIRC was done automagically on my real instal, or did stepconf create the config folder?
also I found the issue, the last two steps are
export PATH=$PATH:[path to the linuxcnc dir]/linuxcnc/scripts/rip-environment
. scripts/linuxcncexport PATH=$PATH:[path to the linuxcnc dir]/linuxcnc/scripts/
. linuxcncexport PATH=$PATH:[path to the linuxcnc dir]/linuxcnc/
