Frida-core bindings about frida-rust

[meme]

Ah, you're just not linking libresolv, you can do so like this in the build.rs:

println!("cargo:rustc-link-lib=resolv");

I encourage you to contribute to this bindings monorepo as the goal is to eventually upstream them into the Frida organization.

I do plan on writing frida-core bindings, if you're interested in working on them now I'm happy to get you started. I will add a frida-core-sys package to this repo.

Ok, this should get you started: 6db9961.

I've added frida-core, frida-core-sys and an example for you (that you can use for development).

If you need any help, let me know 😄

For reference, these are the kinds of errors I'm getting

Hey,

Thanks quick response. I had created a skeleton like the one you pushed before I started encountering these errors, but perhaps this is still something you can help with. The errors don't start occurring until after adding some calls to the sys crate. For example, if in your code, I add the following test function to the Frida struct

impl Frida {
    /// Obtain a Frida handle, ensuring that the runtime is properly initialized. This may
    /// be called as many times as needed, and results in a no-op if the Frida runtime is
    /// already initialized.
    pub fn obtain() -> Frida {
        unsafe { sys::frida_init() };
        Frida {
        }
    }

    pub fn test() {
        unsafe {
            let _main_loop = sys::_frida_g_main_loop_new(std::ptr::null_mut(), 1);
            let _manager = sys::frida_device_manager_new();
        }
    }
}

Then include the crate in another and build it, I get the same error as above
