Symbol Is Not Defined In Current Scope

Fix these problems first and let's see if the symptom persists.Rene Top crazyqg Posts: 84 Joined: Mon Mar 27, 2006 15:23 Re: Error: Symbol #include is not defined in current scope Quote Unread postby crazyqg » Sat Jul 24, 2010 16:03 Dear Brun: Thanks for your help. The following is the error message in compiling.

LINE:0 No symbol cout in current scope This problem has made it into RootTalk on more than one occasion! It can happen if you have not loaded iostream.h, see First Steps: Typing in C++. Doing:- { #include gROOT->Reset(); ...etc... } doesn't work as the Reset() clears the stack and looses the the definitions in the header. Doing:- { gROOT -> Reset(); #include ...etc... } isn't much better. It works the first time but gives the error:- Warning: File "iostream.h" already loaded after that even though the definitions get wiped. Far better to put:- { G__loadfile("iostream.h"); } in rootlogon.C. Can't call Class::MemberFunction() in current scope Check the following:- You https://root.cern.ch/phpBB3/viewtopic.php?t=10873 have misspelt the member function name (if CINT doesn't understand the class name you get the No symbol Class in current scope message). CINT cannot find a member function that matches, in type and number or arguments, those you have supplied. Remember that member functions can be overloaded i.e. there can be several member functions with the same name but with different argument lists. Supplied arguments don't have to be http://www-numi.fnal.gov/offline_software/srt_public_context/WebDocs/Errors/running.html an exact match, for example an integer arg can be converted into a floating point, but there are limits. So check the documentaion, or the code, to see what argument lists are permitted. If calling user classes that:- The ClassDef and ClassImp macros were correctly inserted in the header and implementation files. The dictionary was correctly generated using rootcint with a LinkDef.h file specifies loading of the class globals. Error: class,struct,union or type ... not defined This can be produced if the libraries listed on the link line are not in the right order. The linker may be smart enough to find all the symbols it needs but ROOT may not. ROOT, when building class definition data during execution, loads dictionary data in strict reverse order to the way the libraries appear on the load line. That way lower level class information is available to the system when building class definitions that depend on them. Getting the order wrong may mean that the system fails to find a class definition and prints an error. Undefined symbol With shared libraries, sections of the executable are not loaded until required. Normally any potential unresolved symbol is identified at load time but in exceptional cases, for example virtual destructors to abstr

How can I fix this error, and (more importantly) why am I getting this error?
