#Fix 514 - Remove usage of harfbuzz 1.7.7+ API

[bryphe]

This picks up a change in reason-fontkit (revery-ui/reason-fontkit#27) to remove the use of hb_blob_create_from_file for better compatibility with system-installed harfbuzz.

In #514 , it seems that issues are at least partially stemming from our use of that API, which isn't available in the 1.7.2-ish version we saw.

It sounds like based on @CrossR 's trial that this fixed the issue (although, there was potential still an error with copying configuration)

Based on conversation in Discord - sounds like this fixes it!

Is there a way to clear the build cache? Have pulled tip of master to try this out (should build on 18.04 now, right?) but still getting the same error, it's coming up so fast it's likely from cached artifacts.

[bryphe]

Hmm, if you're building from source - there may be a different error. The build cache should get invalidated when it sees the new dependency for reason-fontkit (you can force it by deleting the _esy folder at the root of the project, though)!

Would you mind sharing out the error message you are seeing?

[awilkins]

Trashed my entire ~/.esy folder - must have had the desired effect because things taking much longer... to get to the next error :-) (was def. the harfbuzz error before, have seen it enough..)

info esy build 0.5.8 (using package.json)
File "assets/configuration/dune", line 4, characters 8-18:

            ^^^^^^^^^^

Ah, that's promising! You'll need to run esy bootstrap now to fix that error 👍

[awilkins]

Huzzah! Built.

esy run

... as soon as I open a file with syntax highlighting it dies though.

$ esy test
error: project is not installed, run `esy install`
  
esy: exiting due to errors above
awilkins@ryoko:~/oni/oni2 (master=)
$ esy install 
info install 0.5.8 (using package.json)
awilkins@ryoko:~/oni/oni2 (master=)
$ esy test
error: project is not installed, run `esy install`
  
esy: exiting due to errors above

That seems a bit odd too.

[bryphe]

Ah, you'll also need to build the textmate service: https://onivim.github.io/docs/for-developers/building#build-the-textmate-service

(That same doc also has instructions for running tests / benchmarks)

[awilkins]

Amazing what you can do when you actually read the docs... can confirm that all builds and runs nicely on Ubuntu 18.04 for me now.

@awilkins - awesome! Glad its working for you 👍
