Example does not work correctly because a setEdge call is not made. I'm guessing this example worked originally, but when you removed re-initializing during polling in commit aaf0438 (Dec 21, 2014), a setEdge call is no longer made. As a result, the example just hangs and never returns.

Not a huge issue, but I was using your example to set up my own waitForEdge and didn't realize I needed to call setEdge first.

I am not shure if I am doing it right, but I can not compile the BeagleBoneBlack-GPIO.cpp example.
With the command

g++ BeagleBoneBlack-GPIO.cpp -o BeagleBoneBlack-GPIO

I get the following error messages:

/tmp/cccx0oPi.o: In function main': BeagleBoneBlack-GPIO.cpp:(.text+0xc): undefined reference toGPIO::GPIOManager::getInstance()'
BeagleBoneBlack-GPIO.cpp:(.text+0x18): undefined reference to GPIO::GPIOConst::getInstance()' BeagleBoneBlack-GPIO.cpp:(.text+0x28): undefined reference toGPIO::GPIOConst::getGpioByKey(char const*)'
BeagleBoneBlack-GPIO.cpp:(.text+0x44): undefined reference to `GPIO::GPIOManager::waitForEdge(unsigned int, GPIO::EDGE_VALUE)

My BeagleBone Black (rev 000C S/N 3114BBBK1759) runs on the newest Angstrom Distribution (BeagleBone Black - 2GB eMMC) 2013-09-04.

Hi I am running debian-buster 10 linux image on the beaglebone black

On cloning the project and compiling it as it is, I get

$ g++ -std=c++17 -lstdc++fs gpio/*.cpp gpio/*.h main.cpp -o example

Any help please ?
