[ECOS] build "Hello world"

[Y.P.Liu.]

Please help me ... I can's build the "Hello world" program .
the list is my environment .
-------
i386 & windows 2000
directory :
eCos : C:\Program Files\Red Hat\eCos
cygwin : c:\cygwin

The library I build which I use eCos Configuration Tool were build in
C:\cygwin\ework\ework.ecc

I edit C:\Program Files\Red Hat\eCos\examples\Makefile
....
.... PKG_INSTALL_DIR = //c/cygwin/ework_install
....
.....XCC = i386-elf-gcc
....

in C:\Program Files\Red Hat\eCos\examples\
I type "gcc -g -I/ework/ework_install/include hello.c
-L/ework/ework_install/lib -Ttarget.ld -nostdlib "

Get the latest eCos from CVS. Version 1.3.1 is obsolete.

That's not the problem here. This is a tools issue:

No, you should type i386-elf-gcc -g -I/ework/ework_install/include hello.c
 -L/ework/ework_install/lib -Ttarget.ld -nostdlib

Using "gcc" is wrong because that is your native gcc, in your case for
cygwin.

You also need to import the redboot_FLOPPY.ecm configuration.
I don't know if you need to do anything else - follow the instructions
in the RedBoot documentation.
