c++ - RTTI check fails on remote Linux machine -

-

i use c++/qt project , facing strange issue.

my application runs fine on native linux machine , windows. problem appears when use remote linux machine execute program , use x windows server (i use xming) view/use it.the debugger points line dynamic_cast fails object pointer(the cast returns nice null) instead of actual object wanted.

i suspect configuration issue must missing enable these runtime checks.

anyone has faced such issues, pointers towards solution welcome.

how have linked? had similar problem our java plug-ins. if dynamic_cast in different dll dll object constructed, rtld_global must set in call dlopen when dlls loaded. if dlls loaded implicitly, whether set depend on how set dll triggering load (which means may have no control on it). in end, had ensure no .so loaded implicitly (by having java load special loader dll, loaded explicitly, in dependency order).

note may not problem; i'm guessing, since don't have enough information. had same symptoms.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
