[ECOS] Information and Help

["Leandro Vieira" <leandro at av dot it dot pt>]

I'm new in ecos. i have subscribed to this mailing list but i
do not know where is the best place(address) where i can ask for help.
like this:

 I have downloaded development tools to develop programs for Intel x86
targets.
 After the extraction process i generated the following directories like in
document:
 	/src/binutils/binutils-2.10
      /src/gcc/gcc-2.95.2
      /src/gdb/gdb-5.0

 After that i go on with following:

 1.I Configured, Built and installed the GNU Binary Utilities.
     mkdir -p /tmp/build/binutils
     cd /tmp/build/binutils
     /src/binutils/binutils-2.10/configure --target=i386-elf \
       --prefix=/tools \
       --exec-prefix=/tools/H-i686-pc-cygwin \
       -v 2>&1 | tee configure.out

     make -w all install 2>&1 | tee make.

 2.I Configured, Built and installed GCC

     PATH=/tools/H-i686-pc-cygwin/bin:$PATH ; export PATH
     mkdir -p /tmp/build/gcc
     cd /tmp/build/gcc
     /src/gcc/gcc-2.95.2/configure --target=i386-elf \
       --prefix=/tools \
       --exec-prefix=/tools/H-i686-pc-cygwin \
       --with-gnu-as --with-gnu-ld --with-newlib \
       -v 2>&1 | tee configure.out

 	make -w all-gcc install-gcc \
      LANGUAGES="c c++" 2>&1 | tee make.out

 3.I Configured, Built and installed GDB

     mkdir -p /tmp/build/gdb
     cd /tmp/build/gdb
     /src/gdb/gdb-5.0/configure --target=i386-elf \
       --prefix=/tools \
       --exec-prefix=/tools/H-i686-pc-cygwin \
       -v 2>&1 | tee configure.out

    make -w all install 2>&1 | tee make.out


 All this process was fine.
 After all this instructions, from eCos Configuration tools i follow the
instructions and i got this:
 		/c/ecos-work/myecos_build
     		/c/ecos-work/myecos_install
    		/c/ecos-work/myecos_mlt
 		/c/ecos-work/myecos.ecc
 		/c/ecos-work/mysrc.ecc =====>this folder was created by me.
						    It's where i put all my sources and the eCos examples(hello.c,
twothreads.c, etc)

     NOTE: In configuration, the template=I386 PC Target and Packages=all.

     IN THIS MOMENT I´M TRYING TO EXECUTE THE PROGRAM EXAMPLES
     AND SOME PROGRAM THAT I BUILT, BUT NOTHING WORK. WHAT I DO AND I WOULD
LIKE TO KNOW IS FOLLOW:

  1. Compiling the sources from bash.exe-2.04$:
  i386-elf-gcc -g -I/c/ecos-work/myecos_install/include
hello.c -L/c/ecos-work/myecos_install/lib -Ttarget.ld -nostdlib
  The result is OK...

  2.from bash.exe-2.04$:
  gdb -nw a.out
  The result is the following message: ... This GDB was configured as
"i686-pc-cygwin" <gdb>

  3.From the gdb consola:
   run
   The result is the following message: Starting Program:
/c/ecos-work/mysrc/a.out
    						    Error Creating process /c/ecos-work/mysrc/a.out, (error 193)

    NOTE:I have tried other solutions but them still not work.
         In this moment i don't use any target, this is, i don't use any
hardware connected to my computer.
         If it's necessary to use a target, i have intention to use a board
with i386 and i have some questions.

	   1.How can i install ecos in this target?
         2.How can i do download to this target?
         3.How can debugg my application?using GDB?
         4.In ecos's document, there is a reference, "Its necessary GDB stub
in target", when you use gdb to debugg.
           whats is GDB stubs and How can i have it in my target?

  4.Can I configure ecos without necessity to use any target(i.e, whitout
Hardwere connected to my computer)?
    If so, How can i do it?

  PLEASE I NEED HELP.
                     BEST REGADS
