Trouble compiling and linking a simple app

[Ricardo Derbes]

Hello, this is a newbie's question:

I'm having trouble trying to build a test application using RTEMS
4.10.2 for a sparc (erc32) project.
I have downloaded sparc-rtems-4.10 toolchain rpm's and installed them
using yum on my OS (fedora20 x86-64), downloaded
rtems-4.10.2 and ran bootstrap, configure & make install without a glitch.
My configuration options are:
--target=sparc-rtems4.10 \
--disable-multiprocessing \
--disable-posix \
--disable-itron \
--disable-networking \
--disable-cxx \
--enable-rtems-debug \
--enable-tests \
--enable-rtemsbsp=erc32 \
--prefix=/home/dev/rtems/
rtemsproduct_erc32 \
CFLAGS_FOR_TARGET='-mcpu=cypress -g -O4'

>From installed directory
/home/dev/rtems/rtemsproduct_erc32/sparc-rtems4.10/erc32/lib, I've
copied librtemscpu.a, librtemsbsp.a, linkcmds, linkcmds.base,
start.o and include/ directory to my workspace lib/ directory

I wrote a short test application:

#define CONFIGURE_INIT
#include "system.h"
#include <stdio.h>
rtems_task Init(rtems_task_argument ignored)
{
    uint32_t count = 0;
    while(1)
    {
        printf("%lu: Hello world, I'm an erc32 application!  \n", count);
        count++;
        rtems_task_wake_after(100);
    }
    rtems_task_delete(RTEMS_SELF);
}

where system.h is:

#include <rtems.h>
#include <bsp.h>

#ifndef SYSTEM_H_
#define SYSTEM_H_

#define STACK_SIZE_MULTIPLIER 2
#define CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER
#define CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER
#define CONFIGURE_MAXIMUM_TASKS             11
#define CONFIGURE_MAXIMUM_MESSAGE_QUEUES    20
#define CONFIGURE_MAXIMUM_SEMAPHORES        25
#define CONFIGURE_MAXIMUM_PARTITIONS        1
#define CONFIGURE_MAXIMUM_PERIODS           10
#define CONFIGURE_MICROSECONDS_PER_TICK     10000
#define CONFIGURE_EXTRA_TASK_STACKS         (CONFIGURE_MAXIMUM_TASKS *
((RTEMS_MINIMUM_STACK_SIZE *
STACK_SIZE_MULTIPLIER)-RTEMS_MINIMUM_STACK_SIZE))
#define CONFIGURE_RTEMS_INIT_TASKS_TABLE
#define CONFIGURE_INIT_TASK_ATTRIBUTES RTEMS_FLOATING_POINT
#define CONFIGURE_APPLICATION_DISABLE_FILESYSTEM

#include <rtems/confdefs.h>
rtems_task Init(rtems_task_argument argument);
#endif /* SYSTEM_H_ */
