Complete HOW-TO Linux Mint 18.1 32/64 RTAI or PREEMPT with RIP install or deb

Yes I do. Deleted kernels from "grub-customizer" app I recovered back.

Everything has gone great since I last posted here but now I am getting adventurous and appears I don't really understand what "master" and "branch" means.
from post 2:
git checkout 2.7 [what ever branch you want, or skip this step for master]
../debian/configure uspace ; debuild -uc -us

The reason I ask is because recently I started using Gmoccapy as my front end. It's version 1.5.7 and I have found that there is a newer version with some features related to a touch screen that I would enjoy.

I used the post 2 method to install linuxcnc and I don't recall what choice I made ( either branch or master ) but it resulted in linuxcnc version 2.7.8. Is there a way to upgrade my existing installation in whole or in part ( to get the new gmoccapy components ) or does it require a complete new installation of LinuxCnc?

This isn't anything urgent but I someday want to take advamtage of future revisions of Linux cnc , in this case Gmoccapy but I am sure there will be others . It appears I should have gone the Rip route but got fixated on getting anything to work !! Lol I will likely start with a new HD to be able to fall back on my current stable build.

The simple way to get LinuxCNC version 8 (master) as an installed system is to use the buildbot.

buildbot.linuxcnc.org

Jake,

Each version of the software is a branch. The current up to date branch is called Master and as its the development branch its unstable. Developers hive off copies into their own branch and work on stuff and if it is approved, it gets merged back into master. Every now and again, master gives birth to a stable branch certified for production. The current stable release is version 2.7. Master is version 2.8. The version is displayed on the splash screen on startup.

Because you have the source installed, you can navigate to the ~/linuxcnc-dev/src folder and type something like the following:
git checkout master
make clean
make -j8
sudo make setuid

make clean clears all of the generated code away so it compiles everything othjerwise it only compiles what it has to but sometimes it gets stuffed up
The -j8 is optional but uses more CPU cores so compilation is meant to be faster

using git checkout you can swap between branches at will and just recompile. I'm using a development branch (dgarr/external_offsets) and often swap back to master as laid out here.

The source code lives here github.com/LinuxCNC/linuxcnc
and there is a drop down in the top left that allows you to look at various branches.

If you are running as run in place you need to type . ~/linux-dev/src/scripts/rip-environment (must include the initial DOT) and after that typing linuxcnc on the command line will start Linuxcnc.

Hey Jake!

If you want to build master follow everything as before. Just do not give this command

The build process will default to 2.8Pre~

If you are using your currently downloaded linuxcnc issue inside of the folder ; linuxcnc/src ; this will reset you to the newest source code ready to compile. As rodw previously mentioned;

Then do the deb build per the instructions.

You guys are awesome! I'll try this in the coming weeks...
