Hi,
2008/2/7, Moritz Lennert <[EMAIL PROTECTED]>:
I just build grass --with-cairo, but when I try to create postscript,
pdf or svg output, I only get empty files.
I'm on debian etch using the libcairo2 & libcairo2-dev 1.2.4-4
packages.
Is this a problem with my cairo implementation or is it a problem in the
cairo driver ?
I tried some example from [1], seems to work here (png,pdf,ps). Debian
Sid (libcairo2 1.4.14).
d.mon x0
d.rast map=elevation.10m
d.vect map=streams width=1 color=blue fcolor=aqua type=area,line
d.vect map=roads width=2
[...]
d.out.file -c sf_cairo format=ps size=800,800
all I get as resulting ps file is this:
%!PS-Adobe-3.0
%%Creator: cairo (http://cairographics.org)
%%CreationDate: Fri Feb 8 09:41:26 2008
%%Pages: 0
%%BoundingBox: 0 0 800 800

/P{closepath}bind def

%%EndProlog
% _cairo_ps_surface_emit_font_subsets
%%Trailer
%%EOF
Same if I use GRASS_CAIROFILE=map.ps and d.mon start=cairo.
With format=png or GRASS_CAIROFILE=map.png I get a nice png file just as
expected.

these are all set to 1

I can see no error message.
Any hints ?
It was as simple as compiling libcairo2 1.4.14...
Now it works !
Maybe we should add a hint somewhere ?
