pthread declaration problem

pthread declaration problem

[jefe goode]

Hi,

I'm a new user of Posix Thread for Win32 (using
pthreadVC.dll) 

A simple test eg does not compile under MS Visual C+
6.0 

The line that fails to compile is

pthread_t tid; //fails to compile
main()
{
}


This implies that the headers are missing or in the
wrong place, but .. they are in the right place

1) the dll pThreadVC.dll is in the c:\windows
directory,
2) the .h files and the .lib file are in the project
directory,
with both LIB and INCLUDE environment variables set to
the project directory.

Does MSVC 6 require any other settings not covered in
the FAQ? Or is there something else needed?

Thanks 

Jefe

Did you #include <pthread.h>?

Thanks Mark,

Yes, it fails to compile and  #include "pthread.h" is
included; 
pthread_t tid; //fails to compile

Try posting the complete program together with the compiler output.

Mark

Complete program below:

compiler output is 7 errors -- (all type info not
found -- the other 6 errors are knock-on ones )

C:\PROJECTS\CP3\Thread1\Thread1.cpp(22) : error C2065:
'pthread_t' : undeclared identifier


Regards and Thanks

--------------- Listing below  --------------

#include "Thread.h"
#include "pthread.h"
#include "sched.h"
#include "semaphore.h"
#include <stdlib.h>
#include <unistd.h>
#include <stdio.h>

#include "stdafx.h"
 void print_message_function( void *ptr ); 

int main(int argc, char* argv[])
{

  pthread_t thread1, thread2;
     char *message1 = "Hello";
     char *message2 = "World";
     
     pthread_create( &thread1, pthread_attr_default,

If using PCH (precompiled headers) under VC6, then all lines before #include
"stdafx.h" are ignored.  Try moving this to the top or turning off PCH.
