installing components

Hi i'm running linuxcnc 2.8.2, and I cannot manage to find the right folder to copy the toolchanger.comp file into the documentations points towards inuxcnc/src/hal/components, closest thing I could find is usr/bin/halcompile or usr/bin/liinuxcnc/modules, and I cannot write anything to both of these, what knowledge am I missing to make this work? thanks

thanks for the answer, I get a " no such file or directory: 'toolchanger.comp"
does the .comp file need to be somewhere specific to run the command? is there any previous step to running it? The file is currently in a folder on my desktop.

thanks a lot, that, along with installing the build-essential compiler, did the trick.

however, I now have trouble getting the hal linkage, my third step gen is defined as per the pncconf wizard syntax, which does not match the code written in the hal linkage component. By the way, it is the boxford240 tool changer I am trying to integrate, I think I definitely lack the proper knowledge to do this right...

So my third stepgen is setup in the hal file, and linked to AXIS_A and JOINT_2 in the ini file,

and it is that part of the code I cannot figure out:

setp stepgen.3.position-scale [AXIS_3]SCALE
setp stepgen.3.steplen 1
setp stepgen.3.stepspace 0
setp stepgen.3.dirhold 16000
setp stepgen.3.dirsetup 31000
## make sure accel and velocity are sensibly low or it will take off!
setp stepgen.3.maxaccel [AXIS_3]STEPGEN_MAXACCEL
### must unlink these 2 to access stepgen.3.position-cmd
### and prevent continual following errors if motor-pos-fb left linked
#net apos-cmd axis.3.motor-pos-cmd => stepgen.3.position-cmd
#net apos-fb stepgen.3.position-fb => axis.3.motor-pos-fb
net astep <= stepgen.3.step
net adir <= stepgen.3.dir
net aenable axis.3.amp-enable-out => stepgen.3.enable

my ini has an Axis_A and Joint_2 section. That's what I thought... i run linux 2.8 but the component was written for a previous version of linuxcnc,

thanks for the reply, since then i've done that, or at least I think I do, and I got the stepper to react to tool change commands, but it is a bit funky, I think I may have left out some parameters I could not find up-to-date references for, like stepgen.X.step and so on, I've posted the issue right here:

I'm not quite sure what belongs where in this forum, so do not hesitate to tell me if I over post or post in the wrong subject.
