Thanks a lot Fabrizio, I corrected the error: I miss to add the POSIX
File IO compatibility layer package to my configuration, So it's clear
that the files are not generated by the configtool

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

Hi,
The problem is that I dont have the<cyg/fileio/limits.h> header in my
install tree also the<cyg/posix/pthread.h> header
and I don't know why the confgtool did not generate these file when I build
the library, Is it a problem of version of the configtool or what??
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.

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
arm-eabi-gcc -c -o hello.o
-I/home/st/config/standard_Posix_install/include -Wall -Wpointer-arith

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.
