c++ - error LNK2019: unresolved external symbol __imp__pthread_self referenced in function -


i'm trying generate pthread lib wp8, lib file seems not work. take function thread_self() example explain it.

first, use command check .lib: dumpbin /symbols pthread_lib.lib

when grep output 'pthread_self', output contains information this: 

01d 00000000 undef  notype       external     | __imp__pthread_self 023 00000000 undef  notype       external     | __imp__pthread_self 01a 00000000 undef  notype       external     | __imp__pthread_self 011 00000000 undef  notype       external     | __imp__pthread_self 011 00000000 undef  notype       external     | __imp__pthread_self 011 00000000 undef  notype       external     | __imp__pthread_self 011 00000000 undef  notype       external     | __imp__pthread_self 011 00000000 sect4  notype ()    external     | _pthread_self 012 00000000 undef  notype       external     | __imp__pthread_self 012 00000000 undef  notype       external     | __imp__pthread_self 018 00000000 undef  notype       external     | __imp__pthread_self 012 00000000 undef  notype       external     | __imp__pthread_self 014 00000000 undef  notype       external     | __imp__pthread_self 011 00000000 undef  notype       external     | __imp__pthread_self 024 00000000 undef  notype       external     | __imp__pthread_self 40d 00000000 sectae notype ()    external     | _pthread_self 059 00000000 undef  notype       external     | __imp__pthread_self 08b 00000000 undef  notype       external     | __imp__pthread_self 054 00000000 sect10 notype ()    external     | _pthread_self 012 00000000 undef  notype       external     | __imp__pthread_self 036 00000000 undef  notype       external     | __imp__pthread_self

it means pthread_self included in lib, doesn't it?

second, created console application project, change settings this:

  1. set "c/c++ -> additional include directories" .\headers;%(additionalincludedirectories)

    (headers dir pthread.h placed in)

  2. set "linker -> additional library directories" .\libs;%(additionallibrarydirectories)

    （libs dir pthread_lib.lib placed in)

  3. append "linker -> input -> additional dependencies" pthread_lib.lib;

and consoleapplication1.cpp is:

#include "stdafx.h" #include <iostream> #include "pthread.h"  using namespace std;  int _tmain(int argc, _tchar* argv[]) {     cout << "test" << endl;     pthread_self();     system("pause");     return 0; }

then when ran it, got error:

error 1 error lnk2019: unresolved external symbol __imp__pthread_self referenced in function _wmain ...\consoleapplication1\consoleapplication1.obj

how check , resolve it?
