How to compile simple program in AOT mode?

[ArtemkaKun]

Hi, I have the following code in fibI.das file

def fibI(n)
    var last = 1
    var cur = 0
    for i in range(n)
        let tmp = cur
        cur += last
        last = tmp
    return cur

[export]
def main
    print("{fibI(6511134)}")

I call das -aot fibI.das fibI.cpp which creates fibI.cpp file

when I'm trying to build executable with the command clang++ -O3 -I../include fibI.cpp -o fib_das, I have an error

clang++: error: linker command failed with exit code 1 (use -v to see invocation)

What I'm doing incorrectly? Unfortunately, I haven't found instruction in the documentation, and I don't understand tutorial02 thing and how I can apply it to my case?

I'm on Arch Linux, with lastest GCC and Clang and dev tools

[ArtemkaKun]

After adding libraries to link clang++ -O3 -I../include fibI.cpp -o fib_das -L../build -llibDaScript, I have just

[borisbat]

tutorial02aot is example on how to hook up aot to the application

[ArtemkaKun]

Thanks for the response. Unfortunately, I neither understand the example (without additional comments or documentation) nor make script (and I'm not sure that I want to learn how to use it).

Would you like to help me with a simple command I can run from the console on the Linux system? The project is very easy and doesn't need any additional hacks (in my opinion at least), so maybe I just need a couple of commands to make it run.

[borisbat]

ok. short version. compile daScriptProfile.exe. run it like this daScriptProfile -test fib_loop.
slightly longer version. AOT needs to be compiled into the executable, which runs interpreted code; aot flag enabled allows code to be picked up

[ArtemkaKun]

Ok, I will try 👍

I would like to use scripts in c++ build-system: https://github.com/MaxwellGengYF/daScript/blob/master/xmake/xmake_func.lua
