Can't find class [org/drinkless/tdlib/Client]

[theapache64]

I've added the depency

implementation "dev.whyoleg.ktd:ktd-api-coroutines-jvm:0.5.0-1.5.4"

I've libtdjni.so in my /usr/local/bin. So I've passed -Djava.library.path=/usr/local/bin to VM options (IntelliJ IDEA Run Configuration)

But when I try to create TelegramClient, am getting below error

Try to load tdlib as library

Hi
Lib already contains prebuilt libtdjni.so inside Jar
In current version, exists bug that first it tries to load it using System.loadLibrary here is the logic for it
It was needed to support Android target
In new version, which is currently in development, it was already fixed. So in you case, you can just remove libtdjni.so from /usr/local/bin. Then it will be automatically extracted from Jar

[theapache64]

I've removed libtdjni.so and treid below code

@ExperimentalTime
fun main(args: Array<String>) {
    val telegram = Telegram(
        configuration = TelegramClientConfiguration(
            maxEventsCount = 1000,
            receiveTimeout = 1.seconds //ms
        )
    )
    val client = telegram.client()
}

But am getting below error

Can't load tdlib

NOTE: I am using Ubuntu 16.04

[whyoleg]

tdlib for linux was prebuilt using github actions, on ubuntu 18.04, OPENSSL version there is 1.1.1d-1+ubuntu18.04
So I think you need to update OPENSSL
even 16.04 is LTS, new LTS will come soon (20.04) so I think I will not support old OPENSSL version

[theapache64]

Okay. I didn't know it was built using Ubuntu 18.04. You found it so fast ⏩ 👍 😄 Good job

[whyoleg]

I will add info about build environment and versions of dependencies during the next release phase. Thx that you found it!

[rndev-io]

I have similar exception. I try to run example on OSX. Build TDLib with this instruction (v1.6.0), move dynamic library to project's root.

@rusnasonov So, the exception is expected... Because that lib uses custom pre-built tdlib with different package names, and in next release it will even change a lot...
So for now, you need to build tdlib using cli module inside project, or I can create jar for you, if needed. In next release it will be just a jar published in github releases, so it will be much easier.
For now: you need to checkout master of ktd and 1.6.0 tag(or any other commit) of tdlib submodule and then in cli/src/main/kotlin/dev/whyoleg/ktd/cli/App.kt change main method to

fun main(args: Array<String>) {
    parser().parse("tdlib -p jvm -t mac".cmd())
}

It will build tdlib, which then can be used with lib as you want

[whyoleg]

For now I will reopen that issue, and before next release document that and provide links to CLI and how to use it

@whyoleg I have tried your approach on macOS Catalina 10.15.7 but getting this error:
