Hi
forgive me if didn't post in the right location, but i'm new on this forum and on arduino
however i'm not new in microcontroller (not an expert either)
i tried your library plus the patch for the leonardo board, i wired the board and the 128x64 lcd display with the PINOUT A recommendation, but when i try to compile i got :
In file included from GLCDdiags.pde:35:
C:\Program Files (x86)\Arduino\libraries\glcd/include/glcd_io.h:35:29: error: ks0108_Leonardo.h: No such file or directory
In file included from C:\Program Files (x86)\Arduino\libraries\glcd/include/glcd_io.h:37,
from GLCDdiags.pde:35:
C:\Program Files (x86)\Arduino\libraries\glcd/include/arduino_io.h:67:2: error: #error "Arduino pin mapping not defined for this board"
i tried a few things (a lot actually) like tampering with the headers (put it back as it was), tried to compile with the Uno board selected, it works, but when i try to upload it fails, i read the forums, search for other entrys who might help me... but now i'm completely stuck...
i'm also pretty sure it's something trivial for a experienced arduino user 
thanks for any help
