Notes on installing Ti's Code Composer Studio V6.2

Why

CCS is released for Linux, but since ~January 2017 it is broken on Archlinux because glibc has been updated. Rather than roll back my entire system, I'm running CCS in a chroot jail, which is something I've never done before and am learning about as I go.

How

This method consumes ~6 gigabytes of space on my disk. FYI.

I'm using directions from here and modifying them to suite my needs.

Download CCS, good luck with Ti's POS website: http://processors.wiki.ti.com/index.php/Download_CCS#Code_Composer_Studio_Version_6_Downloads

Tip: it can get confusing when you're shelling multiple levels into a chroot (user -> root -> chroot -> new user) so to tell if you're in a chroot currently, run ls -di / and if the root directory has an inode other than 2, then you're in a chroot!

Example:

In chroot
# ls -di /
14286889 /
Normal system
$ ls -di /
2 /

Create a chroot:

# mkdir /var/ccs-root            # create an empty folder
# pacstrap -d /var/ccs-root base # Install a base archlinux filesystem to the chroot
# arch-chroot /car/ccs-root      # enter the chroot
## pacman -S vim                 # run this in the chroot

In the chroot, edit /etc/pacman.d/mirrorlist to use Archlinux Archive:

/etc/pacman.d/mirrorlist
################################################################################
################# Arch Linux mirrorlist generated by Reflector #################
################################################################################

# With:       reflector --verbose --latest 40 --number 10 --sort rate --protocol http --save /etc/pacman.d/mirrorlist

Here I've set my chroot's system to be 'stuck' in December 2016. You can try different year/month/day values in that url.

Still in the chroot:

## pacman -Syyuu # force downgrade entire chroot jail
## pacman -U /var/cache/pacman/pkg/ca-certificates-utils-20170307-1-any.pkg.tar.xz # Retain newer certs in order to keep pacman working
## pacman -S xterm base-devel libstdc++5 glibc unzip libcanberra python2 dbus-glib chromium libusb-compat libxss lib32-glibc
## cd /lib
## ln -s libncursesw.so.6.0 libncurses.so.5
## useradd -m ctag

Copy the CCS tarball (web or standalone) into the new user's home directory. Chown it to the user, and then unpack it as the user.

On the host system:

$ xhost +local: # run as _not_ root

Now you should be able to open a window as the jailed user:

#$ cd CCS6.2.0.00050_linux-x64/
#$ ./ccs_setup_linux64_6.2.0.00050.bin

From there you should be free to run the IDE from the chroot. It's not a perfect solution, but it should be a little lighter on system resources than running a VM.

To make launching CCS easier, here are some shell scripts:

In main system:

launch_ccs.sh
#!/bin/bash
chroot --userspec=ctag:ctag /var/ccs-root /home/ctag/ccs.sh
/home/ctag/ccs.sh
#!/bin/bash
/home/ctag/ti/ccsv6/eclipse/ccstudio
