Issues Building on Raspberry Pi 4 (Raspbian)
Hi there,
I'd like to get this Go library building on my Raspberry Pi, but I keep getting this error
pi@raspberrypi:~/gocairo $ make [60/1945]go install github.com/martine/gocairo/cairo
# github.com/martine/gocairo/cairo
../go/src/github.com/martine/gocairo/cairo/path.go:43:13: type [1073741824]PathPoint larger than address space
../go/src/github.com/martine/gocairo/cairo/path.go:43:13: type [1073741824]PathPoint too large

../go/src/github.com/martine/gocairo/cairo/cairo.go:3654:13: type [1073741824]_Ctype_cairo_svg_version_t larger than address space
../go/src/github.com/martine/gocairo/cairo/cairo.go:3654:13: type [1073741824]_Ctype_cairo_svg_version_t too largeWhich I'm not exactly sure how to solve and would appreciate any pointers that people might have? I suspect it is due to the 32-bit architecture of the Raspbian distro, but am not totally sure.
Running uname on the Raspberry Pi reports the following:
Linux raspberrypi 4.19.118-v7l+ #1311 SMP Mon Apr 27 14:26:42 BST 2020 armv7l GNU/Linux
New Go<->cgo pointer rules in 1.6 don't like gocairo
While running https://github.com/dgryski/carbonapi with Go 1.6rc2, I got
http: panic serving 127.0.0.1:44456: runtime error: cgo argument has Go pointer to Go pointer
This error didn't happen with 1.5.
Support for WriteToSVG
Cairo can draw the current surface as an SVG. However, this function is not exposed by the gocairo bindings.
Paths?
Do you intend to support all of the Paths functions and types?

Thanks!
Trouble building on OS X
After some time spent downloading and building various prereqs (like cairo itself, and then fetching XQuartz and rebuilding cairo once I realized that gocairo uses the XLib bindings :), I run into this:
$ CGO_CFLAGS="-I/opt/X11/include" go get -x github.com/martine/gocairo/cairo
