Thank you for reporting this problem. Unfortunately the maintainer of the current two GObject Introspection bindings (@manuelm) is inactive for quite a while, so we had to deprecate them.

So unless this changes, I am afraid we need to exclude these bindings from tests.

[ingwinlu]

fixed by installing libgirepository1.0-dev

//EDIT: I see the deprecated warning now that I have it installed t.t

[markus2330]

We should fix:

• that it says "Please install GObject Introspection development libraries" (or even the name libgirepository1.0-dev see #1016)
• and that it tells about the depreciation right away

does not look like the tests are disabled just because gi is not build

[markus2330]

What do you mean? The gi bindings in this build are included:

-- Include Binding gi_python
CMake Deprecation Warning at src/bindings/gi/python/CMakeLists.txt:32 (message):
  GI bindings have been deprecated


-- Include Binding gi_lua
...

But their test cases fail (so it seems like deprecation was a good idea).

Solution: -DBINDINGS=ALL -> -DBINDINGS="ALL;-DEPRECATED"

Or try to install this lgi module and gi.repository'. (Seems like only some deps are missing for these test cases.)

[ingwinlu]

thanks that was exactly what I needed. I wrongly assumed (without checking) that deprecated warnings mean it would not get build in the current config.
