Is there any known workaround for using external call with non-libc functions?

I know that it's possible with libc, but I haven't figured out a way to use other C libraries.

you can use ffi.DLHandle like dlopen, then use get_function with the fn signature as the type parameter

Ah, you mean like this?

from sys import ffi

def main():
    let handle = ffi.DLHandle("math.h")
    let cos = handle.get_function[fn(FloatLiteral) -> FloatLiteral]("cos")
    print(cos(0.5))

from sys import ffi

def main():
    let handle = ffi.DLHandle("math.h")
    let cos = handle.get_function[fn(FloatLiteral) -> FloatLiteral]("cos")
    print(cos(0.5))

Congrats @🥀Azazelle🥀, you just advanced to level 2!

no that stuff isn't built yet. you have to specify the shared library. it works like dlopen/dlsym
