Code::Blocks pthread example can not compile - c++

Question

Maybe this questions is easy but I can't figure it out how to resolve it:
I try to compile an example which has pthreas on windows 7 (64bit), with Code Blocks I downloaded the prebuild library and set up building_options: the path for the compiler pthreadLib\include and the linker to pthreadLib\lib\x64
The program is:
extern "C"
{
#include <pthread.h>
#include <unistd.h>
}
#include <iostream>
#include <windows.h>
using namespace std ;
void * function1(void * argument);
void * function2(void * argument);
int main( void )
{
pthread_t t1, t2 ; // declare 2 threads.
pthread_create( &t1, NULL, function1,NULL); // create a thread running function1
pthread_create( &t2, NULL, function2,NULL); // create a thread running function2
Sleep(1);
return 0;
}
void * function1(void * argument)
{
cout << " hello " << endl ;
Sleep(2); // fall alseep here for 2 seconds...
return 0;
}
void * function2(void * argument)
{
cout << " world " << endl ;
return 0;
}
In case I comment pthread_create(); function, than it builds. So pthread_t is recognized as a type.
When I try to compile with pthread_create I get an error:
mingw32-g++.exe -L..\libs\Pre-built.2\lib\x64 -LD:\DropBox\WorkUT\Programs\MyODP\libs -o bin\Release\RIP.exe obj\Release\main.o -s ..\libs\Pre-built.2\lib\x64\libpthreadGC2.a ..\libs\Pre-built.2\lib\x64\pthreadVC2.lib
obj\Release\main.o:main.cpp:(.text.startup+0x36): undefined reference to `_imp__pthread_create'
collect2.exe: error: ld returned 1 exit status
Process terminated with status 1 (0 minute(s), 0 second(s))
1 error(s), 1 warning(s) (0 minute(s), 0 second(s))
Do I have to make additional setups in C::B? I tired to add the linker command -lpthread but is not recognized.

Answer 1

After 2 days I figured it out.
First: I installed the minGW 64 for Windows OS.
Next: I set up C::B to use the minGW_64 after this post.
Moreover: I added to the linker libs ..\libs\Pre-built.2\lib\x64\libpthreadGC2.a and ..\libs\Pre-built.2\lib\x64\pthreadVC2.lib. Finally, I added to my project the pthreadGC2.dll (64bit version!).
Lesson learned, don't mix lib. and compiler with 86 and 64.

Answer 2

For Linux
Use sleep(1) in stead of Sleep(1)
