How to use user defined function in THttpServer for control

Newbie

When I use THttpServer in standalone application, I defined a function like void NextEvent() and use THttpServer::RegisterCommand("/NextEvent","NextEvent()") to use it in web page.

But I get error like: use of undeclared identifier ‘NextEvent’, so what’s the correct way to do it, thanks for any help or comment.

Hi Xin,

I am adding @linev in the loop. Perhaps can you add a reproducer for the issue, your platform, ROOT’s version, and the exact error?

Cheers,

Hi,

Are you building application yourself?
In such case you need to create dictionary and add function NextEvent() to LinkDef.h file.
Something like:

#pragma link C++ function NextEvent;

See discussion here for some more details.
