vtable undefined reference

[Manoj Kumar Jha]

Hello,
I am getting error like "vtable undefined reference". I defined all
the constructor, destructor and virtual functions. I am using root
version 5.34/18. The files are in my public area on lxplus. Please see
below on how to reproduce it.

I just went through the same issue today. I added a class to my build, and
somewhere
along the line it wasn't picked up for the linker. Use
$ nm -C <objectfile> | grep (class name)
to check out the status. In my case, I had added a class with exactly the
same
routtines as one before, and tried to rebuild the project from the middle;
some step
in the production of Makefile wasn't done right for the new collection.

here's some more chat about this:

Hi Greg,
Thanks for information. When I switched to Makefile, I am able to compile into sharde lib.

Regards,
Manoj
