Yea, this is the script I pipe to dzen2: http://ix.io/neb (I also tried with ^fn())
It shows a blank bar.

Compiling lemonbar gives the following:
lemonbar.c:51: warning: declaration does not declare anything
lemonbar.c: In function 'fill_gradient':
lemonbar.c:116: error: 'rgba_t' has no member named 'r'

I don't know how to fix that, I can't write C.

Thanks for helping me btw


UPDATE:

I was able to compile lemonbar on openbsd with the following command:
LDFLAGS="-L/usr/X11R6/lib/" CFLAGS="-I/usr/X11R6/include/" CC=egcc gmake

(requires pkg_add xcb gcc)
