You're trying to compile the source files called 'blink' and 'blink.c' and
create an output file called '-lwiringPi'.  In other words, your command
line is the wrong way round.  It should be:

g++ -Wall -lwiringPi -o blink blink.c

I'd suggest writing a Makefile to run the compilation and getting geany to
invoke that.  I wouldn't trust editors to know how to compile things right
themselves (unless they're an IDE, in which case they have a million
dialogues you need to fill out to get it to build)
