Hi all,
I've been rolling my own version of rrdtool 1.3.7 using the opencsw
libraries but another vendor supplied perl distribution. With the last
change to libcairo (r5356), the dependency on librsvg has been removed
to resolve a circular dependency. This has the side effect of
disabling support for SVG graphics (cairo_svg_surface_create) in Cairo.
Unfortunately, this means that rrdtool will not build. I have tried to
build a package out of GAR (which is currently using 1.3.8) and it
won't build either due to the lack of svg support in Cairo. I suspect
this issue will affect the maintainer of rrdtool the next time he
builds an RRDTool package.
This dependency order also has the side-effect of disabling cairo-svg
support in my hand rolled version of graphviz2.
What's the best way to get around this issue, and what is the OpenCSW
plan for rrdtool? I see that Ubuntu Linux is still distributing
RRDTool 1.3.1 in the most recent releases (jaunty and karmic),
possibly due to this problem.
Here's the build error I get when I try to build rrdtool out of GAR
using the most recent libcairo packages:

this is the case. Maybe you need to set LDFLAGS and CPPFLAGS
appropriately
so that compiler and the linker can find libcairo and its header
files. If
you have not installed cairo-svg, you can get it either from its
original home on
http://cairographics.org/releases/
You can find also find an archive copy on
http://oss.oetiker.ch/rrdtool/pub/libs
The last tested version of cairo-svg is 1.4.6.
