[jspahrsummers]

Did you run git submodule update --init --recursive after cloning?

[ahoy-jon]

Arf ... no ! :)

It works better now, but I still have the linking issue.

[jspahrsummers]

That's really weird, because ObjectiveHaskell explicitly links the Data.Text library.

Does running cabal install text say it's already installed and/or fix the linking errors?

Data.Text is already installed.

[jspahrsummers]

Looks like the library was linking against a (slightly) out-of-date version of Data.Text. Would you mind giving the latest master a shot?

EDIT: Ugh, nevermind, getting other errors now. Damnit…

[jspahrsummers]

Alright, do you mind trying cabal install text-0.11.2.0 as well? Sorry for going around and around.

[ahoy-jon]

That's ok ! :)

I had already this version of data.text.

With the master, the problem looks a bit different, is there something with the version of aeson ?

I think Aeson is fine – we're using the same version.

I have one last idea. Can you try adding -all_load to the linker flags of the ObjectiveHaskell static library target? I'm wondering if some of the Data.Text code isn't being copied into the library.

[lukexi]

Hi guys,

I had this same issue just now — I fixed it by updating ObjectiveHaskell's Other Linker Flags to point to the latest versions of text and bytestring I had installed (which you can check with ghc-pkg list), which ended up being bytestring-0.10.0.0 and text-0.11.2.3, which I guess is what my version of Aeson was built against (and likewise for PhotoUploader, had to update to vector-0.10.0.1 and hashable-1.1.2.5).

I imagine the issue is that Data.Aeson specifies a broad dependency on those libraries in its cabal file, which ends up pulling down a different (later) version depending on when you cabal install it.

Tricky! 🐼
