Creating helper scripts...
Performing a clean build of the gcc4mbed samples...
Cleaning up intermediate files...
To build gcc4mbed samples, you will first need to run the following script
so that your environment variables are set correctly:
/home/reyes/github_playground/gcc4mbed/BuildShell
You will want to run this each time you start a new Terminal. You
can simply double-click on this script file from Finder to launch a
bash Terminal that has been properly initialized for building gcc4mbed
based code. Feel free to customize it as you desire.
You can also just edit your existing setup script such as ~/.profile
to update the PATH environment variable to include:
/home/reyes/github_playground/gcc4mbed/gcc-arm-none-eabi/bin
