Doxygen is not generating call graphs for most methods/functions

this seems to be a bug. link to bugreport: https://bugzilla.gnome.org/show_bug.cgi?id=731363

I'm using Doxygen 1.8.7 and Graphviz 2.38. I configured Doxygen to scan a bigger project and generate the documentation as HTML page.

Now, I want/need the caller/called graphs in there and I set every flag that could have something to do with it to 'YES'. But the result is still the same: For 4 methods a called/caller graph is generated but not for the other methods.

I checked the logfile of Doxygen and found exactly 4 entries like this: Generating caller graph for function [...]

For every other class there is only the Generating docs for compound [...]...

Is there a way to get a more detailed log/reasons why doxygen refuses to generate caller graphs for functions?

My doxygen config:

edit

It seems like the call graphs are only generated if the caller/called method is inside the same class. However there seems to be a different behavior for interfaces.

edit2

okay, I created a testproject which, on first glance, seems to confirm what I wrote in the first edit. Here is the testcode:

public class Class1
{
    public void SomePublicMethod()
    {
        Refresh();
    }

    public void SomeOtherPublicMethod()
    {
        SomePublicMethod();
    }

    private void SomePrivateMethod()
    {
        SomeOtherPublicMethod();
        Refresh();
    }

    private static void Refresh()
    {
    }
}

public class Class2
{
    private Class1 test2;
    public void ConstructingClass1()
    {
        Class1 test = new Class1();
        test.SomeOtherPublicMethod();
        test2 = new Class1();
    }

    public void CallingAllPublicsOfClass1()
    {
        test2.SomeOtherPublicMethod();
        test2.SomePublicMethod();

    }
}

Create a .NET 4 or 4.5 solution, create 2 class files and copy&paste the above code in there (should compile). Now let doxygen run over that. It'll create caller/called graphs for all methods in Class1, excluding everything from Class2. Meaning you won't see that SomeOtherPublicMethod is called from Class2.ConstructingClass1.

If you change to class2 there won't be any caller/called graphs at all.

edit3

you can also put both classes in the same file and it still won't generate graphs.

It resolved in this commit. https://github.com/doxygen/doxygen/commit/7edbf2b2e705eccc0d99cce86149228473bc7f3e

So probably the next release will include this bug fix.

Doxygen's code parser (which takes care of the code browser, the cross-references lists and the call graphs) is not perfect, so it probably lost track somewhere. Hard to tell where and why without a code example.

If you want accurate parsing you could try setting

 CLANG_ASSISTED_PARSING = YES
 CLANG_OPTIONS          = <compiler options>

then doxygen will use the clang compiler front-end to parse the code. You will probably get better warnings about what is missing and will need to adjust CLANG_OPTIONS such that these warnings go away in order to be sure you get accurate call graphs.
