nanogui: Thread: need simple makefile for flnx app

Hi,

I'm pretty new to Linux & makefiles.  Could someone please post a simple makefile that builds and links one .cpp file?  The build command I'm using (but isn't working) is gcc hello.cpp -lfgl

Everything compiles and links, but the app doesn't run.  Am I missing some other libs?

Thanks

When you say the app "doesn't run" it's like calling a mechanic
on the phone and telling him that the car that's in your garage
doesn't run.  What's he gonna tell you?
He's got no way to inspect, discover, evaluate anything
because he's got no information.

To get an accurate diagnosis, all information regarding the
issue, including error messages, system type, actual command
line attempted, output expected/output received, etc should be presented.

Regards,

Greg
