gpioplus is a c++ wrapper around the linux gpio ioctl interface. It aims to provide c++ ergonomics to the usage.
Test cases require google{test,mock}, valgrind, and lcov.
For a standard release build, you want something like:
./bootstrap.sh ./configure --disable-tests make make install
For a test / debug build, a typical configuration is
./bootstrap.sh ./configure --enable-tests --enable-coverage --enable-valgrind make make check make check-valgrind make check-code-coverage
