Here is my source, so far just early stages:

When I run this in eclipse it terminates without any warning or
explanation, simply showing Quit in the console. When I try to execute the
application on the Beaglebone Black I get:
[code]
root@beaglebone:/home/debian# ./helloWorldC
./helloWorldC: /lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.17' not
found (required by ./helloWorldC)
[/code]
Any suggestions?
