Setup your computer ¶

Fl-AIR directory ¶

It is advised to put all Fl-AIR related stuffs in the same directory, for example $HOME/flair:

$ mkdir $HOME/flair

Then add an environment variable to your .bashrc with the path of this directory:

$ nano ~/.bashrc

and add

# variable for Fl-AIR
export FLAIR_ROOT=$HOME/flair

reload the script

$ source ~/.bashrc

All Fl-AIR documentation, scripts and CMakeLists.txt will use this variable.

Install packages ¶

Some additional packages are needed. Install them as follows:

• general packages:

  $ sudo apt-get install subversion cmake
  

• an optional IDE (Integrated Development Environment), for example:
  • codeblocks (all Fl-AIR documentation is based on it):

    sudo apt-get install codeblocks codeblocks-contrib
    

  • or eclipse:

    sudo apt-get install eclipse-cdt
    

NB: last codeblocks version has problems with cmake and the code completion plugin. Thus it is recommended to install an older version manually (see next section).

Codeblocks ¶

if Codeblocks is slow or crashes ¶

It seems that auto completion plugin of Codeblocks (version 12.11 and up) does not work very well with a cmake generated project. One solution is to deactivate this plugin, another solution is to install an older version of Codeblocks (10.05), from ​this page. For example on a 64 bits computer:

$ cd
$ wget http://sourceforge.net/projects/codeblocks/files/Binaries/10.05/Linux%20%2864%20bit%29/codeblocks-10.05-1-debian-amd64.tar.bz2
$ tar -xjf codeblocks-10.05-1-debian-amd64.tar.bz2
$ cd amd64
$ sudo dpkg -i *.deb
$ cd ..
$ rm -rf amd64 codeblocks-10.05-1-debian-amd64.tar.bz2

environment variables ¶

When Codeblocks is not launched from command line, it does not read environment variables set in .bashrc. This can make trouble when a CMakelists.txt is modified for example.

To solve this, go to settings/environment menu. Choose environment variables section on the left. Clic on Add and fill the form:

• key: FLAIR_ROOT
• value: path to the FLAIR_ROOT directory

Use rtprio ¶

In order to use FL-AIR without Xenoami, but with high priorities, you need to be root or to allow your user using the following file:

$ sudo nano /etc/security/limits.conf

And add these lines:

your_user		soft	rtprio		99
your_user               hard    rtprio          99

where your_user is your user login. Then logout and login.
