Hm, I’m not familiar with the dlopen crate, had you used it before? I can’t tell what’s going on under the hood!
I was able to get FFI working by looking at https://github.com/jsoftware/stats_jserver4r/blob/4c94fc6df351fab34791aa9d78d158eaefd33b17/source/lib/j2r.c <https://github.com/jsoftware/stats_jserver4r/blob/4c94fc6df351fab34791aa9d78d158eaefd33b17/source/lib/j2r.c> and https://github.com/jsoftware/stats_jserver4r/blob/4c94fc6df351fab34791aa9d78d158eaefd33b17/source/lib/r2j.c <https://github.com/jsoftware/stats_jserver4r/blob/4c94fc6df351fab34791aa9d78d158eaefd33b17/source/lib/r2j.c> I got Haskell bindings: https://github.com/vmchale/j-hs <https://github.com/vmchale/j-hs> but BUT interestingly one test fails on older GHCs… can’t tell why and I never did get around to debugging it. BTW I get error: test failed, to rerun pass '--lib' Caused by: process didn't exit successfully: `/private/tmp/jlang-rs/target/debug/deps/jlang-1c90c81a3f6fae1c --nocapture` (signal: 11, SIGSEGV: invalid memory reference) on mac > On Dec 6, 2021, at 7:22 PM, bill lam <bbill....@gmail.com> wrote: > > I don't know rust at all.
