webserver don't run on ecos : Program received signal SIGBUS, Bus error.


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 -DUEMF -DOS=3D"Linux" -DLINUX -I..
../webcomp.c
In file included from ../wsIntrn.h:114,
                 from ../webcomp.c:21:
../uemf.h:194: redefinition of `struct timeval'
../webcomp.c: In function `compile':
../webcomp.c:121: warning: comparison of distinct pointer types lacks a
cast
make: *** [webcomp] Error 1

but it's easy to resolve it.
i define this : #define WEBS_PAGE_ROM 1 in file wsIntrn.h.


i have at last the binary for my cirrus logic board
so with the red hat ecos configuration tool i run
webs.exe and i have the output below :

the error come from hAlloc that return -1. but i don't know why ?
and that is why i have the "(113) No route to host".

thanks for help.

Guillermo.
