Where is scripts/rip-environment on linuxcnc-2.7-wheezy

I am fed up with lack of documentation and sense in LinuxCNC.
Where is ./scripts/rip-environment located on linuxcnc-2.7-wheezy?

That depends on where you saved your git pull. There in the scripts dir.

If you have compiled run-in-place in will be in:

/path-to-some-directory-you-chose/linuxcnc/scripts

If you haven't yet compiled it wont be there.

If you are running form the live image or installed form the live image there is no need for it.

The wiki & docs are full of information, then there is also the source code to browse through, you wont garner a solid understanding after a few days, it takes a while, the more you use Linuxcnc to control a machine the better the understanding gets.

As for a "lack of sense" can you provide some examples ?

Its pure copy installed from iso. Nothing added from git.
Starting linuxcnc, there is a lot of error like "Module xxx is in use by xxx". Some posts suggests using rip-environment to fix this error, but I cant find rip-environment anywhere.

The rip-environment script sets up the environment variables for linuxcnc when it's compiled for run-in-place and installed via make setuid. You "source" this script before launching linuxcnc.

I think the best course of action would be to upload any logs relating to this issue, along with your hal files and any other files related to the config you are trying to run.

Does this issue appear when you run one of the supplied configs ?

What conditions are you seeing this error ?

Yes andypugh, you probably got a point.
Finally it turned out that there was some problem in .c that I compiled.
Halcompile didn't printed any error message. Starting linuxcnc resulted in error. Recompiling .c didn't fixed this error until a few reset of a whole computer. Error ("Module is in use") was printed for any configuration not matter if it was mine or simulation configuration.
Sad, but it would save a lot of time if I was not looking for rip-environment, because it mention in some post that I read, but focused on compilation itself.
