Reproduced in Binder:

#include <iostream>
#include <vector>

std::cout << "some output" << std::endl;

std::vector<int> test() {
    std::vector<int> result;
    return result;
}

input_line_8:3:25: error: function definition is not allowed here std::vector test() { ^ Interpreter Error:

It should work if you define the function in a dedicated cell.

Yes it is a parsing issue in cling. The next version should come with a fix for this after cling 0.6 is out.

I just saw cling 0.6 released 4 days ago...

Yes, I've been working on the conda recipe since yesterday.

@SylvainCorlay I want to know how to upgrade the cling on Ubuntu... I have updated all of my packages with conda yesterday, but the cling --version is still 0.5...
