So I was just try to use Haskell with Capstone. I note the problems here for reference:

In the capstone source, there is a union with no name, unamed union. c2hs build will fail on this case, because the current c2hs version is 0.28.6 released 2018 while support for unamed union is merged in the master branch in 2019 but not released yet. haskell/c2hs#233.

We may need to reference a c2hs commit and update the code to parse unamed union. After that, resolve any new issue.

So here is the code of capstone v4.0.1 as a reference.

Capstone 5.0 is about to be released, it's better to target it instead:

• https://github.com/capstone-engine/capstone/releases
• A Letter Prior to the Official Release of Capstone v5.0 capstone-engine/capstone#2053

There is also a huge project to automate updates for different architectures to stay relevant with minimum effort, but it will bring some API differences: capstone-engine/capstone#2015

Please let us know if you have any feedback about the current state or the auto-sync project.
