I finaly got the symbol to be found...
I used extern "C" in addonn code itself.
The reason for it not recognizing extern "C" earlier was, for compiling the
addon, I needed to install haiku_devel, which upgraded the system. This
means the changed header file TrackerAddOn.h no longer contains `extern "C"
void populate_menu`. Due to this, its name was C++ mangled.
But now that I can call `populate_menu (entry_ref dir_ref, BMessage *msg,
BMenuItem* item)`, where I'm passing the BMenuItem of the add on item
created at
https://github.com/Hrily/haiku/blob/63ede39cc8b8149b906969666c0f1bc7ad80193c/src/kits/tracker/ContainerWindow.cpp#L235
I can neither access `item->Submenu()` nor `item->Menu()`. Both turned out
to be null.
Any idea on how I can access the add on menu?

So any idea on how to make it's name to just `populate_menu`.
Just declaring it as extern "C" should work. So it would seem your add-on
was not compiled using the modified .h file, or the prototype does not
match.
You can declare it as extern "C" directly in your add-on sourcecode
however, it will save you having to change system header files for
experimenting. Check with readelf until the add-on is properly built, then
try again.
