[ECOS] POSIX layer and pthread:Unable to make the application

[ECOS] POSIX layer and pthread:Unable to make the application

[medamine]

Hi every one,

I use
Hardware: ST STM3210E EVAL board
Packages: posix
in the section:POSIX threads

POSIX pthread implementation header Enabled=True Value=0
POSIX mutex/cond var implementation header Enabled=True Value=0

and I got the pthread.h :

#ifndef CYGONCE_ISO_PTHREAD_H
#define CYGONCE_ISO_PTHREAD_H
/*===========================================
//
// pthread.h
//
// POSIX pthread functions
//
//===========================================

/* CONFIGURATION */

#include <pkgconf/isoinfra.h> /* Configuration header */

/* INCLUDES */

#ifdef CYGINT_ISO_PTHREAD_IMPL
# ifdef CYGBLD_ISO_PTHREAD_IMPL_HEADER
# include CYGBLD_ISO_PTHREAD_IMPL_HEADER
# endif
#endif

#ifdef CYGINT_ISO_PTHREAD_MUTEX
# ifdef CYGBLD_ISO_PTHREAD_MUTEX_HEADER
# include CYGBLD_ISO_PTHREAD_MUTEX_HEADER
# endif
#endif

#endif /* CYGONCE_ISO_PTHREAD_H multiple inclusion protection */

/* EOF pthread.h */

After that, i wrote this application using thread

#include <pthread.h>
#include <stdio.h>
#define NUM_THREADS 5

void *PrintHello(void *threadid)
{
long tid;
tid = (long)threadid;
printf("Hello World! It's me, thread #%ld!\n", tid);
pthread_exit(NULL);
}

int main (int argc, char *argv[])
{
pthread_t threads[NUM_THREADS];
int rc;
long t;
for(t=0; t<NUM_THREADS; t++){
printf("In main: creating thread %ld\n", t);
rc = pthread_create(&threads[t], NULL, PrintHello, (void *)t);
if (rc){
printf("ERROR; return code from pthread_create() is %d\n", rc);
exit(-1);
}
}

/* Last thing that main() should do */
pthread_exit(NULL);
}

but when i build the application withe eCos library, i got these errors

/STM3240G/fork$ make hello

make: *** [hello.o] Error 1

First view is that the thread functions doesn't exist in the header 
thread.h, the configtool generate uncompleted headers,

Please i need your help.

Thanks a lot.

Hi,
also this seems a problem on the eCos library configuration generated
with the configtool.
I used the configuration I suggested in a previous post (and that you
adopted!) and I'm able to compile your example. Some warnings, but no
errors.

The inclusion tree is the following:
"pthread.h"
"pkgconf/isoinfra.h"
"cyg/posix/pthread.h"

The latter include the declarations that you miss. Please, check it.
Your "standard_Posix" configuration should be good.

Re: [ECOS] POSIX layer and pthread:Unable to make the application

[Fabrizio Carrai]

Please check the value of the "POSIX pthread implementation header"
(Macro name is CYGBLD_ISO_PTHREAD_IMPL_HEADER). The value should be
<cyg/posix/pthread.h>
If so, something went bad in the building: **delete** the target
_install and _build directory and start a build from scratch.

Ciao
Fabrizio
