If there are no errors, it is ready for the next step which is to compile the files. There may be some
warning messages during the compile, ignore them. To compile, type
make and it may take a few
minutes to compile.
debian@beaglebone:~/mraa/build$
make

To install what was built the older revision of the code will need to be removed. To do this it is an
apt-get uninstall of the mraa files done in Task 1e Step 2. Type
sudo apt-get remove
libmraa1 libmraa-dev mraa-tools
.
8 Install the build with elevated privileges sudo make install . This will place all the executables
and link libraries in the correct locations.
