3.2 Configuring the Software

Once the prerequisites have been satisfied, you can go ahead and configure the software.

To do this, take the tarball upad.tar.gz which you have downloaded or been provided with by your vendor and unpack it by running the command

tar -xzf upad-0.0.tar.gz

This will create a directory called upad-0.0 into which you should enter.

Next run the command

./configure --with-riot-base=my-riot-base

which configures the software to suit your local computer. The string my-riot-base you should substitute with the base directory of the RIOT source which you installed at Prerequisites. 2

The following example shows the configuration of µPad when the RIOT source has been installed in the directory called RIOT in the user’s home directory.

configure: creating ./config.status

config.status: creating config.h

If any dependencies have not been fulfilled, or if there is any problem configuring the software then an error message will be shown. You should address the problem and repeat this step before continuing.



If you want to build only the local computer part of µPad, and not the controller part, then you can pass the special value of my-riot-baseno’.
