[ECOS] Help! Some runtime problems

[ECOS] Help! Some runtime problems

[Robert Allen]

Hi guys,
    I have a multi-threaded application written in
C++. It compiled well. when I try to run it, this is
what I'm getting --

Program received signal SIGTRAP, Trace/breakpoint
trap.
[Switching to Thread 2]
0x0000ede0 in _exit (n=24)
    at
../../../../../../newlib-1.12.0/newlib/libc/sys/arm/syscalls.c:104
104    
../../../../../../newlib-1.12.0/newlib/libc/sys/arm/syscalls.c:
No such file or directory.
        in
../../../../../../newlib-1.12.0/newlib/libc/sys/arm/syscalls.c
Current language:  auto; currently c

I don't understand this error. can someone please help
me on this.

Thanks.

Rob.

This looks to me like you have built a stand-alone newlib application
and not an eCos application. Go back and reread the User Guide.

Thanks Nick. But still I couldn't figure out where I'm
going wrong. Please look below for the Makefile I'm
using for my application. Can someone point to me
where I'm going wrong. 

Thanks.

You've left out ECOS_GLOBAL_CFLAGS and ECOS_GLOBAL_LDFLAGS which may
have options that affect things. In particular the absence of
-nostdlib, which is in ECOS_GLOBAL_LDFLAGS, is probably the cause of
your problems.

Try using my build_Makefile scripts - this makes building eCos
application makefiles much simpler (and they work :-)
  http://www.mlbassoc.com/examples/
There are a couple of different examples, using different approaches
to Makefile construction.

Thanks Gary and Nick. Now it looks fine.

Re: [ECOS] Help! Some runtime problems & Linking

[Robert Allen]

Hi,
   I followed the advice given by Gary and Nick. It
makes fine and the program looks to eecute fine. But
its only when I specify some breakpoints, I get weird
things, like I'm not being able to see the step by
step execution. Sometimes I get the following error:

Breakpoint 1, cyg_user_start () at mcu_firmware.cc:35
35      mcu_firmware.cc: No such file or directory.
        in mcu_firmware.cc

I have attached the makefile below.
Thanks for your help in advance.

Rob.
