First of all you need cmake installed on your system. into main directory do the following:

• mkdir build
• cd build
• cmake ../
• make
• make install

This will create 2 statics libraries libspidev-lib.a and libspidev-lib++.a You can link thoses libraries against your own code.

The sample directory contain a sample usage for c and for c++ you can compile it from main directory in this way.

• g++ sample/spidev-testcpp.cc -lspidev-lib++ -o spidev-testcpp
• gcc sample/spidev-testc.c -lspidev-lib -o spidev-testc
