[Geany-devel] [pretty-print plugin] Failed to compile geany-plugins with latest geany

[Lex Trotman]

Hi,

Putting extern will make that a declaration which is what you want in
a header that is used several times, but you have to define it
somewhere, usually in a file that is only used once like a .c file.

Cheers
Lex
