32 pecl-cairo master tests fail with cairo 1.8 about cairo HOT 5 CLOSED

@auroraeosrose
I should add: it works nevertheless.. maybe you can exclude the tests/functions if underlying cairo does not support it ?
would that be possible/OK to you ?

from cairo.

First of all - what is the actual failure in the test files? there should be .out and .diff files so you can see the actual problem

So 1.8 is the supported version from redhat? all the 1.10 and higher stuff should be in ifdefs

from cairo.

From my memory, it's mostly "function undefined".

ifdef is a brilliant idea.
If OK for you, i'd check the function reference of cairo, set all tests to functions not implemented into according ifdef's and make test again, not expecting errors.
Posting them here if there any errors left.

Our Developers told me today, what they use from your extension works like a charm, so it's not exactly "incompatible" with 1.8.8

from cairo.

There's other stuff already ifdef'd out by version, just need to find the version those things were introduced in :)

from cairo.

libcairo 1.10 is now 6 years old... and since I don't have a good list of symbols introduced and
we know it works perfectly with 1.10 and higher, I'm explicitly upping the version requirement

May not be the fix you want, but now config will tell you when your version is too old instead of hitting missing symbols
