Rootcling dictionary for function

[VolkerH]

Hi Experts,

I have a header and source files in which I define a class GClient and a function startGClient(const char* s). In the linkdef file, I have

#pragma link C++ class GClient;
#pragma link C++ function startGClient(const char*);

Both are linked in the library libRSGClient.so.

If I start root and load the library, trying to call startGClient(“a”), gives an error:

[] startGClient("a")
input_line_28:2:3: error: use of undeclared identifier 'startGClient'
 (startGClient("a"))
  ^

However, if I first inspect the class GClient, i.e.

[] .class GClient

and then call the function, everything works.

Is there anything I miss? The same worked with cint for years.

Thanks and best regards,
Volker

Hi,

To have the function visible in the prompt you need to parse the header file defining the function.
Just do in the ROOT prompt
root> .L GCClient.h
or
root>#include “GCClient.h”
