Hi,
I have seen there was a similar topic at this address,
[url]Mysterious Warning: no public constructor
this was long time ago, so I am not sure if it applies to my case.
Here is my problem
I have a base class, named TRestRun, and a derived class named TRestG4Run
TRestRun derives at the same time of TRestMetadata::TObject
This works fine, I can create the ROOT dictionary and load my library in ROOT without problems. Everything works fine.
However, when I want to make TRestRun an abstract class, by re-definning an existing method into a pure virtual method I get the following warning when calling the destructor of TRestRun (using “delete restG4Run;”)
Warning in <TKey::TKey>: since TRestRun has no public constructor
which can be called without argument, objects of this class
can not be read with the current library. You will need to
add a default constructor before attempting to read it.
The method defined in TRestRun (abstract class) is
and in the derived class (where the method is implemented) it is
My ROOT version is 5.34
Do you have any suggestion to resolve this problem?
Thanks!
