Q: Why do I get a “command not found” return when I try to build the sample application using Cygwin?

A:
The build.sh file must use Unix end of line terminations. Change the line endings to Unix by using "dos2unix" preceding the build.sh command. For example:
user@xyz /home/logic/sample_app/2.10/led_flasher
$ dos2unix build.sh
build.sh: done.
user@xyz /home/logic/sample_app/2.10/led_flasher
$ ./build.sh
