Overview

CCSv5 is the first CCS release to add Linux host support to the CCS product line. This wiki page describes important information regarding supported Linux distributions (and other dependencies), emulators, simulators and devices. It also lists CCS features that are not yet supported on Linux.

For CCSv6 please view this topic Linux_Host_Support_CCSv6

Linux Distributions

As there are many versions and distributions of Linux, we are not able to test and support every flavor. To operate CCS is dependent on a number of libraries, those libraries are listed below along with the Linux distributions that CCS is tested on.

Dependencies

Starting with CCSv6, the CCS installer will check for the required dependencies as part of the installation process. The packages mentioned in the missing dependency list should be installed before proceeding. The distro-specific instructions below should help in finding and installing these packages.

For releases prior to v6, you can manually check for dependencies. The easiest way to do that is to use the script provided here: Checking Linux Dependencies for CCS.

Your linux distribution's package management system will allow you to search for these libraries and install the necessary packages (and dependent packages of those packages) to get them. Or they can be downloaded and built from source.

An additional dependency issue is that the installed version of gdk on some distros may expose different function signatures than expected. This manifests as CCS exiting early with the error message: “symbol lookup error: /opt/ti/ccsv5/ccs_base/DebugServer/linux/libxul.so: undefined symbol: gdk_screen_get_resolution”. SUSE 10.2 exhibits this issue.

The easiest way to resolve this is to install xulrunner-191 (on SUSE: sudo zypper install mozilla-xulrunner191), and then add the new gdk libraries to LD_LIBRARY_PATH (on SUSE: export LD_LIBRARY_PATH=/usr/lib/firefox/lib/:$LD_LIBRARY_PATH) before starting CCS. This issue is only needed when using the internal web browser (help and the TI Resource Explorer are web based). If those features are not needed, CCS can be used with the existing gdk as long as the workspace does not auto-load them.

Testing

CCS will work on many different Linux distributions.  However as there are so many it is not possible to test CCS on all of them.  These are the distributions that are in the CCS test lab and thus officially supported.  In general we test CCS on the latest LTS (Long Term Support) version of Ubuntu as well as the most recent version of Ubuntu and a version of RedHat (or equivalent CentOS) for enterprise customers.

Installation Types

It is possible to install CCS in both single user and multi user environments.

Single-user

This is an installation that will just be used by a single user account. In this case it is recommended that you install CCS into a location within your own home directory. Run the CCS installation with normal user permissions and afterwards run the driver installation script afterwards as sudo or root. This way you will be able to update CCS when running as a normal user. If you run the installation as root then you will only be able to update as root.

Multi-user

This is an installation that is installed into a shared location and is used by multiple users. Run the CCS installation as sudo or root. You will not have to run the driver installation script afterwards as the drivers will be installed by the main installation. Individual users can then run CCS and folders will be created under the home folder to contain their settings. Updating CCS will only be possible by someone with root/sudo permissions which is desired for a shared installation. There is more information on the directories created by CCS at install time and runtime in this topic: Multi-User_CCS_Installs

Installation Instructions

  • Check that your Linux distribution has all the dependent libraries. The easiest way to do that is to use the script provided here: Checking Linux Dependencies for CCS. To run the script you will need to install the 32-bit application support libraries.  On Ubuntu the command would be sudo apt-get install ia32-libs  for other distributions it may be yum install instead of apt-get install
    • Note that for some distributions the command to install the necessary dependencies is listed below. Note that dependencies can change with CCS versions so it is worth running the script just in case CCS has changed since the instructions below were generated.
  • Download the install file and untar it into a temporary folder.
    • For example, tar xvfz /tmp/ccsv5_install setup_CCS_5.x.x.0xxxx.tar.gz
  • There are two different options for installing CCS:
    • Single-user installation
      • From a terminal, run the installer ./ccs_setup_5.x.x.xxxxxx.bin &
      • Navigate to <install_dir>/ccsv5/install_scripts, e.g. cd ~/ti/ccsv5/install_scripts
      • Run the install_drivers script as root. sudo ./install_drivers.sh
    • Multi-user installation (install as root/sudo)
      • From a terminal, run the installer sudo ./ccs_setup_5.x.x.xxxxxx.bin &
  • A license file is required to run CCS

Below are sample installation instructions for some distributions including the steps to install the necessary libraries. 

Ubuntu 14.04 64-bit (incomplete...)

  • Resolve Dependencies
    • To allow the dependency checker built into CCSv6 to run, install these libraries:
      • sudo apt-get install libc6-i386 libx11-6:i386
    • Try installing the following list of dependencies before running the CCS installer
      • sudo apt-get install libc6-i386 libasound2:i386 libjpeg62:i386 libatk1.0-0:i386 libcairo2:i386 libdbus-1-3:i386 libdbus-glib-1-2:i386 libfontconfig1:i386 libfreetype6:i386 libgconf-2-4:i386 libgdk-pixbuf2.0-0:i386 libgtk2.0-0:i386 libice6:i386 lib32ncurses5 liborbit2:i386 libpango-1.0-0:i386 libpangocairo-1.0-0:i386 libpangoft2-1.0-0:i386 libpng12-0:i386 libsm6:i386 lib32stdc++6 libusb-0.1-4:i386 libx11-6:i386 libxext6:i386 libxi6:i386 libxrender1:i386 libxt6:i386 libxtst6:i386 lib32z1 libgnomevfs2-0:i386 libcanberra-gtk-module:i386
    • libudev0 will still be flagged as missing. Still looking at how to resolve that dependency. The following is a work around:
      • sudo apt-get install libudev1:i386
      • sudo ln -sf /lib/i386-linux-gnu/libudev.so.1 /lib/i386-linux-gnu/libudev.so.0

Ubuntu 13.10 64-bit

  • Resolve Dependencies
    • The ia32-libs package has been deprecated. Instead install the libc6-i386 package to be able to run the dependency checker:
      • sudo apt-get install libc6-i386
    • download and extract the CCS dependency checker from here. Note that if you don't install the 32-bit libc6 library you won't be able to run it.
    • Try installing the following list of dependencies before running the checker
      • sudo apt-get install libc6-i386 libasound2:i386 libjpeg62:i386 libatk1.0-0:i386 libcairo2:i386 libdbus-1-3:i386 libdbus-glib-1-2:i386 libfontconfig1:i386 libfreetype6:i386 libgconf-2-4:i386 libgdk-pixbuf2.0-0:i386 libgtk2.0-0:i386 libice6:i386 lib32ncurses5 liborbit2:i386 libpango-1.0-0:i386 libpangocairo-1.0-0:i386 libpangoft2-1.0-0:i386 libpng12-0:i386 libsm6:i386 lib32stdc++6 libusb-0.1-4:i386 libx11-6:i386 libxext6:i386 libxi6:i386 libxrender1:i386 libxt6:i386 libxtst6:i386 lib32z1 libgnomevfs2-0:i386
    • run the checker ./check_depends.sh
    • install the necessary packages to resolve the dependencies. The checker will list the missing .so files, you can use apt-file search to determine which package they are part of. Note that you will likely have to install apt-file first and run the update command to build its list of packages. i.e. run sudo apt-get install apt-file and then apt-file update then you can run a check on a .so file with a command like this apt-file search libjpeg.so.62. It tells me that the item is part of libjpeg62. Then to install it I would run sudo apt-get install libjpeg:i386 The ":i386" at the end is important.
    • download either the web installer or the full offline image
    • run the checker one more time to make sure you have all the dependencies installed correctly (repeat above steps if needed)

Ubuntu 13.04 64bit

  • Resolve Dependencies
    • install the 32-bit application support libraries: sudo apt-get install ia32-libs
    • download and extract the CCS dependency checker from here. Note that if you don't install the 32-bit libraries you won't be able to run it.
    • run the checker ./check_depends.sh
    • install the necessary packages to resolve the dependencies. The checker will list the missing .so files, you can use apt-file search to determine which package they are part of. Note that you will likely have to install apt-file first and run the update command to build its list of packages. i.e. run sudo apt-get install apt-file and then apt-file update then you can run a check on a .so file with a command like this apt-file search libjpeg.so.62. It tells me that the item is part of libjpeg62. Then to install it I would run sudo apt-get install libjpeg:i386 The ":i386" at the end is important.
    • typical command to resolve dependencies sudo apt-get install ia32-libs libjpeg62:i386 libgnomevfs2-0:i386 liborbit2:i386**download either the web installer or the full offline image
    • run the checker one more time to make sure you have all the dependencies installed correctly (repeat above steps if needed)
  • Install CCS
    • if you chose the full image then extract it
    • run the installation program
    • install the drivers. Go to the /ccsv5/install_scripts and then run the script: sudo ./install_drivers
  • Notes
    • To get an xds200 emulator to work I had to get an updated Linux rules file. The fix will be in CCSv5.5 but you can get it and the instructions on this forum thread

Ubuntu 12.10 64bit

  • Download the install file and extract it with Archive Manager (running from a pre-extracted archive does not work)
  • Install dependent libraries (32bit application libraries + others)
    • sudo apt-get install ia32-libs libjpeg62:i386 libgnomevfs2-extra:i386 liborbit2:i386
  • Run the installer (if installing as user run the driver installation script afterwards)
  • Instructions tested with:
    • CCSv5.4.0
    • MSP430UIF (F2131)
    • XDS100v2 (F28027 LaunchPad)
    • BH XDS560v2 USB (OMAPL138 LCDK)
    • BH 510L (F28335 Exp)
    • SD XDS560v2 STM Traveller USB (OMAPL138 LCDK)
    • SD XDS200 USB (OMAPL138) had to lower JTAG TCLK to get a reliable connection

    • SD XDS510 USB Plus (OMAPL138 LCDK)

Ubuntu 12.04 64bit

IMPORTANT!!!! The newly released Ubuntu 12.04 64-bit has instabilities with aptitude (update manager) that may prevent installing the required 32-bit libraries. Check its Release Notes and bugs here and here

  • Download the install file and extract it with Archive Manager (running from a pre-extracted archive does not work)
  • Install 32bit application libraries sudo apt-get install ia32-libs
  • Install other required libraries sudo apt-get install libjpeg62:i386 libgnomevfs2-0:i386 liborbit2:i386
  • Run the installer (if installing as user run the driver installation script afterward
  • If the either the ia32-libs installation or the CCS installation still won't run try running sudo apt-get update or run the Ubuntu update manager to make sure all libraries are up to date. Then install ia32-libs again, then try the CCS installer.
  • Ubuntu currently has a bug that causes messages of the form "wrong ELF class: ELFCLASS64" to be printed in the console. These seem to be harmless.

A couple of users have reported seeing the error message GLib-WARNING **: getpwuid_r(): failed due to unknown user id  when trying to run the installer. The root cause of this problem isn't known but it appears to be a bug in pam_sss and/or nss_sss libraries. They have been able to work around it by installing nscd or by running the installer as sudo.

Fedora 20 64bit

IMPORTANT! These installation instructions are for reference only. Fedora distributions are not officially tested and/or supported.

  • Run sudo yum upgrade to make sure your packages are up to date.
  • Download and extract the CCS dependency checker.
  • Install the following packages: sudo yum install libusbx.i686 alsa-lib.i686 atk.i686 dbus-glib.i686 gdk-pixbuf2.i686 pango.i686 libgdk-x11-2.0.so.0 libXt.so.6 libcanberra-gtk2.i686 GConf2.i686 gnome-vfs2.i686 ORBit2.i686 libpng12.i686 ncurses-libs.i686 libusb.i686
  • Run the dependency checker ./check_depends.sh to see if all dependencies are met.
  • Download the CCS installer and make it executable: chmod +x ccs_setup_5.xxx.bin.
  • Run the installer: sudo ./ccs_setup_5.xxx.bin
  • Reboot after installation. This is necessary on Fedora 20 for the drivers to be recognized after udev restarts.
  • Known Issues
    • I haven't been able to get XDS200 or Spectrum Digital XDS510 emulators to work. XDS100 and XDS560v2 products have been fine.
    • Desktop icons are not visible. Need to run from terminal or from activities
    • You will see a message saying "Failed to load module "pk-gtk-module". This does not seem to impact operation of the product. Looks like GTK2 pk-gtk-module is deprecated and causes this message to appear for many applications.
    • Trace Control does not open. This is the GUI used to configure the trace receiver such as ETB or XDSPROTRACE. CCSv5.4 should resolve this as there is a new UI for configuring trace that does not have the same dependencies.

If you recieve the error: libjvm.so: cannot restore segment prot after reloc: Permission denied when you try to launch CCS, you will need to turn off SELinux using setenforce 0.

Updating

Note that you need to have the same permissions to update an installation as you do to install. In general the user that does the installation should be the one that does the update. I.e. if you install as user then you can update as user but if you installed as root then you will NOT be able to update as user. In multi user scenarios the person who did the installation should be the one doing updates.

Troubleshooting

General

Fedora Licensing

Fedora changed the names of the network interface from ethX to emX in F15 and newer. This causes problems with licensing software.

If you decide to install a commercial software which needs to check its FLEXnet license (from Flexera) on a server running F15, you will need to provide the hostid of your server to the software company by running the lmhostid executable, which gives the MAC address of your server.

With network interfaces named like em0, em1 ..., you will get a null MAC address: $ ./lmhostid lmhostid - Copyright (c) 1989-2008 Acresso Software Inc. All Rights Reserved. The FLEXnet host ID of this machine is "000000000000"

Which is the MAC address of the loopback (lo) interface.


Therefore, you need to change the network interface name back to ethX. FLEXnet license manager only understand network interfaces starting with eth.

Add the kernel option biosdevname=0 in /etc/grub.conf: $ su -

  1. GRUBBYLASTKERNEL=`/sbin/grubby --default-kernel`
  2. /sbin/grubby --update-kernel=${GRUBBYLASTKERNEL} --args='biosdevname=0' &>/dev/null

Edit file /etc/udev/rules.d/70-persistent-net.rules and add the 2 following lines: SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:11:22:33:44:10", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:11:22:33:44:11", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

Be sure to put your MAC addresses in the fields above.

Rename the ifcfg-* config files in /etc/sysconfig/network-scripts to match the eth0 and eth1 device names.

Then reboot and re-run lmhostid to get: $ ./lmhostid lmhostid - Copyright (c) 1989-2008 Acresso Software Inc. All Rights Reserved. The FLEXnet host ID of this machine is ""001122334410 001122334411""

Support for Older Kernels

  • USB permissions are handled successfully in older kernel versions. The installer does not attempt to add the fstab entries required by older kernel versions.

Installing on 64bit Distributions

  • CCS is a 32bit application that can run on 64bit Ubuntu distributions when the 32bit library support package (ia32-libs and ia32-libs-gtk) is installed. See the Ubuntu 32bit vs 64bit Wiki topic for more detailed information as well as other alternative ways of running 32bit applications.
    • on Ubuntu run: sudo apt-get install ia32-libs
    • on Fedora run: sudo yum install alsa-lib.i686 atk.i686 cairo.i686 dbus-glib.i686 gdk-pixbuf2.i686 pango.i686 libgdk-x11-2.0.so.0 libXt.so.6 PackageKit-gtk-module.i686 libcanberra-gtk2.i686

Mozilla library version conflicts (v5.2.x and earlier)

Prior to CCSv5.3, if you see CCS start, display the splash screen, and then disappear after a few seconds, you may be running into a Mozilla library version conflict.

Some background info: CCS uses a Mozilla technology called XPCOM. The same set of libraries are used in Firefox. On Linux, the default Eclipse internal browser is Firefox. When CCS starts with a new workspace (as would normally be the case with a fresh install), the welcome page is displayed. The welcome page uses the internal browser. If the internal browser opens and forces the load of a version of XPCOM that is not compatible with CCS, you may see CCS crash and exit.

To avoid the welcome screen opening by default, browse to the ccsv5/eclipse/plugins/*branding*/ folder, and edit the plugin_customization.ini file. At the end of the file, add a new line containing the text: org.eclipse.ui/showIntro = false

CCSv5.3 removed this dependency.

FAQ

Error "Please set DISPLAY. Code Composer Studio v5 cannot be installed in console mode."

A: Assuming DISPLAY is in fact set correctly then this error is caused by the 32bit library support package not being present. Install the necessary 32bit support libraries to resolve.

Installer exits immediately without doing anything

A: This error is caused by the 32bit library support package not being present. Install the necessary 32bit support libraries to resolve.

Failure installing 32bit libraries

A: Try running the OS update tool first. I have found on Fedora and later Ubuntu distributions that if my OS is not up to date then the libraries will fail to install.

Missing menu

  • If using Ubuntu 10.10 or newer with the Unity Desktop framework (default in 11.x) the main menu in CCS to not appear. Instead unity puts the menu at the very top of the screen and you need to place your mouse there and it will appear.  Note that if you don't like this Unity feature the issue can be worked around by running CCS with the following command

env UBUNTU_MENUPROXY=0 ccstudio
