error: implicit declaration of function 'raft_heap_get'

When trying to build the dqlite-1.12.0 tests on Fedora 35 I get the following error:

Is this due to an "old" GCC version?

Which version of raft are you using? raft_heap_get is only exposed in the latest release, v0.16.0.

[ganto]

Ok, thanks. I haven't seen this version dependency being mentioned anywhere. Will try again with the latest raft.

[cole-miller]

Yes, I think our documentation on the corresponding dqlite release was lacking -- sorry about that. It's been updated to mention the dependency on raft v0.16.0.
