hi all, i receive the following mail : It looks to me like this 
user is not using the correct Makefile.  I just = tried it here and 
everything works just fine.  Here are the steps I = took: 1. 
Unpack the 'tar', file. ok 2. cd .../ECOS (... is where I unpacked 
the files) ok 3. "edit" Makefile These lines need 
to be modified. There are two extant examples in the 
= file. ##PKG_INSTALL_DIR :=3D /work/net_mbx/install ok -> 
PKG_INSTALL_DIR :=3D /d/eCos2/conf_install ##COMMAND_PREFIX :=3D 
powerpc-eabi- ok -> COMMAND_PREFIX :=3D arm-elf- ##CFLAGS 
:=3D -mcpu=3D860 -msoft-float $(DEBUG) ok -> CFLAGS :=3D 
-mcpu=3Darm7tdmi -D__EDB7209 -D__EDB7212 $(DEBUG) 4. make The 
'make' output quoted below tells me the user is not using the ECOS = makefile 
since the -DECOS flag is not present. As for who to ask for additional 
assistance, the best way to get answers = is via the mailing list 'ecos-discuss@sourceware.cygnus.com' 
There are = many knowledgeable folks on this list, not just the eCos 
developers. = Chances are, you'll get a speedy response, with the added bonus 
that the = rest of the eCos community gets to benefit from the questions and 
= answers. i still have the error gcc -o webcomp -O2 -DWEBS

cirrus logic board so with the red hat ecos configuration tool i 
run webs.exe and i have the output below : *** 09:43:51 Run
