dependencies - Undefined reference to Class::Class() and functions in one file? c++ -


everything compiling fine, , i've looked through 10 different questions on here trying solve including this, this, , this. please don't kill me, i've been beating head against wall 3 hours now. i've tried building offending file , seems build fine, when build project still throws same errors.

i've tried moving include ".h's" cpp files when possible of time still didn't help. when change 

bitboards *newboard = new bitboards;

to 

bitboards *newboard;

the error on line goes away, still gives me "undefined refrence to" newboard-> functions.

is there else glaringly obvious, or not, should try?

the errors pop in logic file here: ai_logic.cpp

 //master bitboard turn bitboards *newboard = new bitboards; ^^here //master zobrist object ai turn zobristh *mzobrist = new zobristh;  //master evaluation object - evaluates board position , gives int value (- black) evaluatebb *meval = new evaluatebb;  newboard->constructboards(); ^^and here every instance of newboard-> below

ai_logic.h:

#include <string> #include <stack> #include <thread> class pieces; class zobristh; class bitboards; class movegen; class evaluatebb; class hashentry;  class ai_logic { //stuff };

ai_logic.cpp

#include "ai_logic.h"  #include <algorithm> #include <stdlib.h> #include <time.h> #include <iostream>  #include "externs.h" #include "move.h" #include "evaluatebb.h" #include "bitboards.h" #include "movegen.h" #include "zobristh.h"

bitboards.h

class movegen; class zobristh; class move;  class bitboards { //stuff };

bitboards.cpp

#include "bitboards.h" #include <cmath> #include <random> #include <iostream> #include <string> #include <cstdio>  #include "externs.h" #include "movegen.h"

i think problem might come movegen.h/cpp i'm not entirely sure

movegen.h

#include <iostream> #include <string> #include "move.h"  class pieces; class bitboards; class zobristh;   class movegen { //stuff };

movegen.cpp

#include "movegen.h" #include "bitboards.h" #include "pieces.h"    

#include bitboards.cpp

in ai_logic file seemed trick. absolutely no idea why.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
