Quick start Ubuntu 16.04
Contents
Set root password
Amazingly, after installing Ubuntu, I have no idea how to log in as root! If something goes wrong with sudo, you will be glad you first set the root password.
sudo passwd root
sudo configuration
You can configure sudo to not ask for your password:
sudo addgroup admin sudo adduser $USER admin sudo sh -c "echo '%admin ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers"
Switch shell from dash to bash
sudo rm /bin/sh sudo ln -s /bin/bash /bin/sh
Packages to install
General utilities and RR SDK required packages
These are packages that are typically required to put your system in shape for general utilities, and also packages necessary to compile typical RidgeRun SDKs.
sudo apt install vim touch install_packages.sh vim install_packages.sh
then add the following on it:
#!/bin/sh apt update # To get the latest package lists apt upgrade apt install build-essential fakeroot graphviz gdb openssh-server git zip subversion git-core nfs-kernel-server nfs-common meld portmap xinetd tftpd tftp curl libncurses5-dev texinfo picocom quilt autoconf libcrypt-ssleay-perl libusb-dev libexpect-perl mono-devel libgtk2.0-dev bison flex xclip liblzo2-dev uuid-dev python-virtualenv terminator tree doxygen vlc libdbus-glib-1-dev iftop libxml2-dev gstreamer-tools libgstreamer0.10-dev libgstrtspserver-0.10-dev libreadline-dev valac libtool subversion libterm-readkey-perl libwww-perl gparted gperf libgmp-dev libgmp3-dev libmpfr-dev libmpc-dev imagemagick ddd cmake cmake-curses-gui ccache mtd-utils intltool xsltproc libusb-1.0-0-dev libbz2-dev libjpeg62 autoconf libcrypt-ssleay-perl libusb-dev libexpect-perl libcrypt-ssleay-perl libusb-dev libgtk2.0-dev meld asciidoc ubuntu-restricted-extras autopoint unzip
Then you should type:
chmod +x install_packages.sh sudo ./install_packages.sh
Common packages used by RR Developers
RidgeRun developers often install:
# Editors sudo apt install -y geany geany-plugin-addons emacs eclipse-cdt # Version Control sudo apt install -y git subversion # Development Tools sudo apt install -y gdb valgrind cscope oprofile # Miscellaneous sudo apt install -y hamster-indicator pidgin filezilla gimp wireshark wireshark-doc xdot # GStreamer 0.10 sudo apt install -y gstreamer-tools gstreamer0.10-alsa gstreamer0.10-nice gstreamer0.10-plugins-base gstreamer0.10-plugins-base-apps gstreamer0.10-plugins-base-dbg gstreamer0.10-plugins-good gstreamer0.10-plugins-good-dbg gstreamer0.10-pulseaudio gstreamer0.10-tools gstreamer0.10-x libgstreamer-plugins-bad1.0-0 libgstreamer-plugins-bad1.0-dev libgstreamer-plugins-base0.10-0 libgstreamer-plugins-base0.10-dev libgstreamer0.10-0 libgstreamer0.10-0-dbg libgstreamer0.10-dev # GStreamer 1.0 sudo apt install -y gstreamer1.0-clutter gstreamer1.0-espeak gstreamer1.0-fluendo-mp3 gstreamer1.0-libav gstreamer1.0-libav-dbg gstreamer1.0-nice gstreamer1.0-plugins-bad gstreamer1.0-plugins-bad-dbg gstreamer1.0-plugins-bad-faad gstreamer1.0-plugins-bad-videoparsers gstreamer1.0-plugins-ugly gstreamer1.0-plugins-ugly-dbg gstreamer1.0-pocketsphinx libgstrtspserver-1.0-0 libgstrtspserver-1.0-0-dbg libgstrtspserver-1.0-dev libnice-dbg libnice-dev
Tuning bash startup script
echo "alias h='history 100'" >> $HOME/.bashrc echo "alias e='source make env 2> /dev/null'" >> $HOME/.bashrc
When you're ready you can source the file:
source $HOME/.bashrc
SDK downloads
The location /opt/ridgerun/downloads is conveniently used to hold all the packages and tarballs downloaded by the RR SDK, and is convenient because it can be re-used if you have more than one RR SDK installed in your machine.
sudo mkdir --parents /opt/ridgerun/downloads sudo chmod ugo+rwx /opt/ridgerun/downloads
If you have another computer setup that has built the RidgeRun SDK before, you will find it much faster on the first build if you copy the downloads directory to your new machine.
EXISTING_MACHINE_IP=192.168.0.1 scp -r $EXISTING_MACHINE_IP:/opt/ridgerun/downloads/* /opt/ridgerun/downloads
Host ldconfig does not support ARM architecture
If you get the error
Kernel panic - not syncing: No init found. Try passing init= option to kernel.
when you first boot your target hardware, you may have run into the ldconfig issue. On the host computer check the file length of
$DEVDIR/fs/fs/etc/ld.so.cache
If that file is less than 200 bytes long, you need to use a different version of the host application ldconfig.
When the 2.19 version of ldconfig that comes with Ubuntu 14.04 tries to create the /etc/ld.so.cache shared library cache on the target file system, it ignores all ARM shared libraries. This is a known defect. To work around the defect, the RidgeRun SDK has been enhanced to fetch the 2.15 version of ldconfig and use it to create the target file system /etc/ld.so.cache file.
If you are using a older version of the RidgeRun SDK, you can follow these commands to resolve the issue.
cd $DEVDIR mkdir tmp cd tmp wget https://launchpad.net/~ubuntu-security/+archive/ubuntu/ppa/+build/5061964/+files/libc-bin_2.15-0ubuntu10.5_i386.deb dpkg-deb -x libc-bin_2.15-0ubuntu10.5_i386.deb libc-bin_2.15-0ubuntu10.5_i386 install -Dm 755 libc-bin_2.15-0ubuntu10.5_i386/sbin/ldconfig.real $DEVDIR/bsp/local/bin/ldconfig.2_15 sed -i -e 's!LDCONFIG?=.*!LDCONFIG?=ldconfig.2_15!' $DEVDIR/bsp/classes/common.defs cd $DEVDIR rm -rf tmp
Build the $DEVDIR after you run the steps mentioned above and check for the ld.so.cache filesize is changed to not less than 200 bytes long.
Building a RR SDK
After the steps above, you can try out building your RR SDK. See the SDK User Guides for reference.
Steps needed to install toolchain on versions newer than ubuntu 12.04
In order to run the toolchain installer you need to install the 32-bits libs, since this versions removed ia32-libs ia32-libs-gtk packages from the repository you need to run
sudo apt-get install libgtk2.0-0:i386 libxtst6:i386 gtk2-engines-murrine:i386 lib32stdc++6 libxt6:i386 libdbus-glib-1-2:i386 libasound2:i386
Special steps when installing the dvsdk
Running the dvsdk installer, use the --forcehost switch to enable the installation, for example:
./dvsdk_dm368-evm_4_02_00_06_setuplinux --forcehost
note: During the DVSDK installation process you will be asked for the toolchain's path, assuming that you installed it on /opt, the path that you need to provide is /opt/codesourcery/arm-2009q1/bin/
Packages that will be asked by the Ridgerun SDK
sudo apt-get install libdbus-glib-1-dev libgtk2.0-dev bison flex libglib2.0-dev sudo apt-get install python-prettytable lzop libpopt-dev binutils-dev libiberty-dev
Disabling auto mount
Since the SDK is used to write a bootable images to an SD card, it is often useful to disable automount. When automount is enabled, the SDK can not reliabily write to the SD card if the card is under the control of the Nautilus file system manager.
Run:
dconf-editor
Browse to org.gnome.desktop.media-handling and uncheck the automount key.
Switching desktop environments
I haven't gotten used to Unity yet. I prefer Gnome panel. You could start by loading the official Gnome Ubuntu distro, which is likely easier. If you already installed Ubuntu, then you might find these steps helpful.
To see what desktops are available, I ran:
aptitude search desktop
I found one that looked good, so I ran:
sudo apt-get install ubuntu-gnome-desktop gnome-panel
Pick gdm the Gnome Display Manager, when asked.
Get gnome panel to auto-start, by adding it to your session properties (fill in all boxes with gnome-panel)
gnome-session-properties
Log out, and when you go to log back in again, first click on the Ubuntu circle icon in the dialog box asking for your password and select GNOME Flashback (metacity).
Customizing desktop
Run dconf Editor and wander around org.gnome tree. Here are some of my favorites:
- org.gnome.desktop.wm.preferences
- button-layout : close,maximize,minimize:
- auto-raise : select
- auto-raise-delay : 500
- num-workspaces : 4
- workspace-names : ['mail', 'chat', 'customer 1', 'personal']
Creating ssh key for github
To make git clone work easily, I created and uploaded an ssh key to github.com. Create a key using:
YOUR_EMAIL_ADDRESS=foo.bar@baz.com ssh-keygen -t rsa -C "$YOUR_EMAIL_ADDRESS"
Then browse to http://github.com, log in, click on your name in the upper right corner, then pick SSH keys from the left side panel. You can view the key you created by running:
cat ~/.ssh/id_rsa.pub
Resize Window Border To Small
If you have having trouble resizing the windows because the borders are too small, you might find these ideas helpful:
- Hold down the Alt key and use the middle mouse button to resize the window from anywhere inside the window.
- Edit /usr/share/themes/Ambiance/metacity-1/metacity-theme-1.xml then log out and log back in again.
