c++ - Symbol in Text section yet undefined -

-

i have built xerces on hp-ux using c++. builds executables link against libxerces-c-3.1.sl. while running of them getting symbol not found error:

shlib_path=../lib ./domcount /usr/lib/dld.sl: unresolved symbol: _znk11xercesc_3_113xmlbigdecimal10getrawdataev (data)  /home/build/hp-ux/lib/libxerces-c-3.1.sl [hp aries32]: core file 32-bit pa-risc application [hp aries32]:   /home/build/hp-ux/bin/domcount saved /home/build/hp-ux/bin/core.domcount segmentation fault (core dumped)

i executed nm command shows symbol undefined. can see xercesc_3_1::xmlbigdecimal::getrawdata() in text section well.

nm -pxan libxerces-c-3.1.sl | c++filt | grep getrawdata ../lib/libxerces-c-3.1.sl:0x002c2ac8 t  xercesc_3_1::xmlabstractdoublefloat::getrawdata() const ../lib/libxerces-c-3.1.sl:0x002c5390 t  xercesc_3_1::xmlbigdecimal::getrawdata() const ../lib/libxerces-c-3.1.sl:0x004818c4 t  xercesc_3_1::xmldatetime::getrawdata() const ../lib/libxerces-c-3.1.sl:0x00000000 u  xercesc_3_1::xmlbigdecimal::getrawdata() const ../lib/libxerces-c-3.1.sl:0x002c2ab0 t  xercesc_3_1::xmlabstractdoublefloat::getrawdata() const ../lib/libxerces-c-3.1.sl:0x002c9988 t  xercesc_3_1::xmldatetime::getrawdata() const ../lib/libxerces-c-3.1.sl:0x002c5378 t  xercesc_3_1::xmlbigdecimal::getrawdata() const ../lib/libxerces-c-3.1.sl:0x002c99a0 t  xercesc_3_1::xmldatetime::getrawdata() const

can me understand how can symbol undefined if in text section? or misunderstanding something?

edit: in code can see inline function definition inside code, why symbol not found issue:

inline xmlch*  xmlbigdecimal::getrawdata() const {     return frawdata; }

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.
