A few years ago, I got make check to work with the image target, with help:
https://lists.cairographics.org/archives/cairo/2013-June/024411.html
This still works.
But I just tried it with the xcb, and the xlib target, running on Xvfb,
creating my own reference directory, and testing against it, and that
fails. I've read through test/README. What does it take to get it to
work?
Script that I ran to test it:
#########################################################################
Xvfb :3 &
git clean -xfd
./autogen.sh --prefix=$HOME/install --enable-gl --enable-xcb
make
DISPLAY=:3 CAIRO_TEST_TARGET=xcb make test
cp -a test/output/ $HOME/source/cairo-ref.xcb.xvfb.1
git clean -xfd
./autogen.sh --prefix=$HOME/install --enable-gl --enable-xcb
make
DISPLAY=:3 CAIRO_REF_DIR=$HOME/source/cairo-ref.xcb.xvfb.1 CAIRO_TEST_TARGET=xcb make test
cp -a test/output/ $HOME/source/cairo-ref.xcb.xvfb.2
git clean -xfd
./autogen.sh --prefix=$HOME/install --enable-gl --enable-xcb
make
DISPLAY=:3 CAIRO_REF_DIR=$HOME/source/cairo-ref.xcb.xvfb.2 CAIRO_TEST_TARGET=xcb make test
#########################################################################
(Yes, I did that an extra time, just to make sure it didn't help.)
The contents of test/output and the reference directory ended up being
basically identical. There are a few files that only exist in the xvfb.2
directory. And there are a couple tests that started working on that last
run, which I'm pretty sure shouldn't have changed anything?

I'm not sure what information is useful to give you.
