How to check if SonarLint plugin is actually analyzing my code in Eclipse?

Question

I have installed a SonarLint plugin in my Eclipse, and now I am trying to test it on my toy C++ project. I see no errorrs/warnings/alerts about my code, even though I deliberately made it really broken. Is there a way to check or confirm that SonarLint actually attempted to verify my source code?

This is my test program source:

struct C
{
    bool x;
    bool y;
};

int f(C c)
{
    int * p = nullptr;
    *p = 3;
    if (c.x)
        if (c.x)
            return true;
    if (c.x)
            return false;

    return *p;
}

int main()
{
    C c;
    int i = f(c);
}

I am convinced that I have installed the SonarLint plugin, because whenever I start Eclipse, I get an error message "SonarLint - Rules not available": "Some rules are not available until some requirements are satisfied". When I click on "Details", I get "Some analyzers can not be loaded.".

The Console output is the following:

Based on [this bug report][1] I gather that this should not affect the SolarLint's ability to analyze my C++ code.

But when I change my code and compile the above code, I do not get any warning from SonarLint. When I right-click my project name, I get "SonarLint" item in the context menu; when I expand it, I have item "Analyze"; when I select it, "SonarLint Report" window opens, but it contains zero messages. Surely at least one bug should have been found for my above code?

Is there a way to verify what is wrong? Or if my expectations are incorrect?

Ok, I know. SonarLint does not support C++. It is other SonarSource tools that work with C++.
