comp --install no such command

Hi I want to try to install a component for my lathe toolchanger.
I adapted the emcoturn one a little bit and wanted to test it.
when I run the sudo comp --install emcochanger
I get an error: comp no such command
what do I need to install to make that work?
I am running linux mint with linuxcnc 2.7.10 (if i remember correctly)

The hal component compiler has been re-named halcompile

for sudo halcompile --install emcochanger
I get no such command aswell

Did you install the LinuxCNC dev package?

yes just checked, and it seems I dont have it.
how do i install it apt-get install linuxcnc-dev does not exist

If you use the synaptics package manager do any LinuxCNC packages show up? (use search)
If you don't have a standard LinuxCNC installation it may not have the repositories setup properly

Another possibility, if this is a run-in-place installation, you would need to run the rip script to setup your search
paths to include the proper directories

I used this tutorial LinuxMint Prempt to install linuxmint, linuxcnc and prempt kernel.
Sry I got no clue what you mean by rip script

In synaptec two pckages show up: linuxcnc-doc-en and linuxcnc-uspace

on my pc there is a folder called linuxcnc-dev, from the tutorial I followed. I still can't use the halcompile command.
in the linuxcnc-dev folder under scripts there is a rip script but I didn't try to run it yet as I got no clue what it does.

RIP stands for Run In Place and it allows you to run a linuxCNC installation that is not installed in the normal system directories
Its handy for development since it allows easy access to multiple LinuxCNC versions on a single machine

One disadvantage is that neither LinuxCNC or any of its utilities will be found with the default executable search path
in your shell, so to setup the search paths (and manual paths etc) you need to source a script that sets up these paths

thats what

. rip-environment

does

I ran the ./rip-environment command and this is what happened:
This script can be used in one of two ways.

It can be loaded in the context of your shell, by executing
. ./rip-environment
after this, commands like 'linuxcnc', 'halrun' and so on refer to the
version in this directory, instead of to an installed version of
linuxcnc (if any)

Second, it can be used to run a command in this directory without
modifying the environment of the calling shell:
./rip-environment command...
such as
./rip-environment halrun foo.hal
./rip-environment linuxcnc configs/.../foo.ini

Sry I am a complete linux noob. what do i need to do to make the halcompile permanently accessibile?
