Error: Dynamic Loading Error: build/src/libtdjson.so.1.8.6: cannot open shared object file: No such file or directory at new TDLib about tdl

Thanks for the quick response and the suggestion. The output of that is

Error: Command failed: ldd libtdjson.so

} not a dynamic executable

After seeing this message, I was able to identify and fix the issue. Documenting the details here for others' reference.

Google Cloud Functions execution environment for nodejs16 runtime is Ubuntu 18.04, but prebuilt-tdlib is built against Ubuntu 20.04. So I spinned up a Ubuntu 18.04 docker to build tdlib myself. The problem is that I'm using an M2 Mac (Apple Silicon), so the object is actually built with ARM aarch64 architecture.

$ file libtdjson.so
libtdjson.so: ELF 64-bit LSB shared object, **ARM aarch64**, version 1 (SYSV), dynamically linked, not stripped

I ended up creating a repo and built the tdlibjson.so object with Github Workflow with steps borrowed from here. And the shared object built from this process can be successfully used to create a TDLib instance on Google Cloud Functions.

Hi! Try to execute ldd ./build/src/libtdjson.so.1.8.6, for example: require('child_process').exec('ldd ./build/src/libtdjson.so.1.8.6', (err, stdout, stderr) => console.log(err, stdout, stderr))

bew install tdlib - fixed all my problems with it
