undefined reference

[gogo2464]

I did go run .\testing.go

on

package main

import (
    "cryptatools"
    "fmt"
)

func main() {
    myvar := cryptatools.AlphabetNewEmpty() //Alphabet

    fmt.Println(myvar)
}

The line

import ( "cryptatools" "fmt" )

Does not immediately triggers any error.

Sadly I am having a lot of undefined references error.

My python bindings are already working contrary to go bindings.

May it be due to the undone update to uniffy 0.24 please? I read this https://github.com/NordSecurity/uniffi-bindgen-go/pull/13

[arg0d]

Currently Go bindings only work with uniffi 0.23. If you are trying to mix different versions, you are by design going to encounter errors. This is because uniffi ABI is unstable, and you would encounter strange bugs if versions don't match. Consider downgrading your project to use uniffi 0.23 for the time being.

[gogo2464]

Could I compile the existing forked pr in order to solve the issue please?

[arg0d]

I'm not sure what you mean. It doesn't look like the PR is finished. Is downgrading the uniffi version that you use to 0.23 not an option?

[gogo2464]

Not really because I already have python bindings with the version 0.24 of uniffy.

[gogo2464]

might work with cargo install uniffi-bindgen-go --git https://github.com/dignifiedquire/uniffi-bindgen-go --branch upgarde-uniffi-24. I am testing.

[arg0d]

I wouldn't use it until the PR is actually finished. It might look like it works, but there might be some hidden edge cases where it doesn't work right.

Not really because I already have python bindings with the version 0.24 of uniffy.

Are you using 0.24 specific features? I don't see why you shouldn't be able to downgrade to 0.23 for Python bindings.

[gogo2464]

Because I upgraded my code to uniffy-rs 0.24 for python bindings. I want to reuse the same code for the go bindings.

[gogo2464]

@arg0d https://github.com/NordSecurity/uniffi-bindgen-go/issues/16#issuecomment-1717894747 are you sure it is not only because I am on Windows? Maybe it is because I am on windows and because I am both on windows and old uniffy-rs version.

I will test at the end of the PR if I can directly use it on windows.

[gogo2464]

hi. is it fixed?

[arg0d]

0.24 was skipped and not released, so you need to choose between 0.23 and 0.25.

[gogo2464]

sure perfect! I will pick 0.25 directly!!! 0.25 is ok?

[arg0d]

yes, 0.25 is supposed to work fine.

[gogo2464]

cool! I will test on my project!
