Forums - Setup environment variables for command line access to Xtensa tools

Can anyone explain to me how to do setup things as below instructions:

3. Setup environment variables for command line access to Xtensa tools.

 

a. Place the following variables either in a script to be sourced later, or in a .bashrc (or equivalent) startup file.

 

NOTE:The value to fill in for <TOOL_INSTALL_DIR> is the value recorded from step 2-a. As an example: /home/user/xtensa

 

  export XTENSA_INST=<TOOL_INSTALL_DIR>

  export XTENSA_CORE=KF

  export XTENSA_ROOT=$XTENSA_INST/XtDevTools/install/builds/RE-2013.3-linux/KF

  export XTENSA_SYSTEM=$XTENSA_ROOT/config

  export XTENSA_TOOLS_ROOT=$XTENSA_INST/XtDevTools/install/tools/RE-

  2013.3-linux/XtensaTools

  export LM_LICENSE_FILE=~/license.dat

  export PATH=$PATH:$XTENSA_TOOLS_ROOT/bin

 

b. Either source the script created in 3-a, or open a new terminal if using .bashrc in 3-a.

 

c. Test the environment variable settings by compiling a simple program.

    echo 'main(){}' > test.c

    xt-xcc test.c
