Linux Installation Instructions for Arch and CentOS
Ninja Build System
Ninja is a faster build system than Make and the PX4 CMake generators support it. To install a recent version, download the binary and add it to your path:
mkdir -p $HOME/ninja cd $HOME/ninja wget https://github.com/martine/ninja/releases/download/v1.6.0/ninja-linux.zip unzip ninja-linux.zip rm ninja-linux.zip exportline="export PATH=$HOME/ninja:\$PATH" if grep -Fxq "$exportline" ~/.profile; then echo nothing to do ; else echo $exportline >> ~/.profile; fi . ~/.profile
Installation Instructions for Uncommon Linux Systems
The build requires Python 2.7.5. Therefore as of this writing Centos 7 should be used. (For earlier Centos releases a side-by-side install of python v2.7.5 may be done. But it is not recommended because it can break yum.)
The EPEL repositories are required for openocd libftdi-devel libftdi-python
wget https://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm sudo yum install epel-release-7-5.noarch.rpm yum update yum groupinstall “Development Tools” yum install python-setuptools easy_install pyserial easy_install pexpect yum install openocd libftdi-devel libftdi-python python-argparse flex bison-devel ncurses-devel ncurses-libs autoconf texinfo libtool zlib-devel cmake
Note:You may want to also install python-pip and screen
Additional 32 bit libraries
Once the arm toolchain is installed test it with:
If you receive the following message
bash: gcc-arm-none-eabi-4_7-2014q2/bin/arm-none-eabi-gcc: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
Then you will also need to install other 32-bit libraries glibc.i686 ncurses-libs.i686
sudo yum install glibc.i686 ncurses-libs.i686
Pulling in ncurses-libs.i686 will pull in most of the other required 32 bit libraries. Centos 7 will install most all the PX4 related devices without the need for any added udev rules. The devices will be accessible to the predefined group ' dialout'. Therefore any references to adding udev rules can be ignored. The only requirement is that your user account is a member of the group 'dial out'
Ensure you have the multilib repository enabled.
sudo pacman -S base-devel lib32-glibc git-core python-pyserial zip
Then use it to download, compile and install the following:
yaourt -S genromfs python-empy
The user needs to be added to the group "uucp":
sudo usermod -a -G uucp $USER
After that, logging out and logging back in is needed.
Log out and log in for changes to take effect! Also remove the device and plug it back in!**
GCC Toolchain Installation
Execute the script below to install 5.4:
pushd . cd ~ wget https://launchpad.net/gcc-arm-embedded/5.0/5-2016-q2-update/+download/gcc-arm-none-eabi-5_4-2016q2-20160622-linux.tar.bz2 tar -jxf gcc-arm-none-eabi-5_4-2016q2-20160622-linux.tar.bz2 exportline="export PATH=$HOME/gcc-arm-none-eabi-5_4-2016q2/bin:\$PATH" if grep -Fxq "$exportline" ~/.bash_profile; then echo nothing to do ; else echo $exportline >> ~/.profile; fi popd
Now restart your machine.
If using Debian Linux, run this command:
sudo dpkg --add-architecture i386 sudo apt-get update
Then install the 32 bit support libraries (this might fail and can be skipped if running a 32 bit OS):
sudo apt-get install libc6:i386 libgcc1:i386 libstdc++5:i386 libstdc++6:i386 sudo apt-get install gcc-4.6-base:i386
Check the version by entering the following command:
The output should be something similar to:
arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors) 5.4.1 20160609 (release) [ARM/embedded-5-branch revision 237715] Copyright (C) 2015 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
If you get the following output, make sure you have the 32bit libs installed properly as described in the installation steps:
arm-none-eabi-gcc --version arm-none-eabi-gcc: No such file or directory
