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

Can you send the _entire_ output from "make"?  The line quoted above is quite
troublesome since it does not have the appropriate flags.  E.g. when I build
this [on a different platform], I get lines such as:

sh-elf-gcc -c -o main.o -ml -m3 -ggdb -Wall -O2 -DWEBS -DUEMF -DWEBS_PAGE_ROM -DOS="eCos" -DECOS
-D__ECOS -D__NO_FCNTL=1 -I.. -Wall -I/work/net2_hp/install/include -ffunction-sections
-fdata-sections -Wp,-MD,main.d main.c
main.c: In function `send':
main.c:252: warning: passing arg 2 of `write' discards qualifiers from pointer target type
sh-elf-gcc -c -o webrom.o -ml -m3 -ggdb -Wall -O2 -DWEBS -DUEMF -DWEBS_PAGE_ROM -DOS="eCos" -DECOS
-D__ECOS -D__NO_FCNTL=1 -I.. -Wall -I/work/net2_hp/install/include -ffunction-sections
-fdata-sections -Wp,-MD,webrom.d webrom.c

Notice the -DECOS and -DWEBS -DUEMF -DWEBS_PAGE_ROM.  I'm still not convinced that
you are following the build instructions properly.  If you don't, the outcome is
certainly questionable.

Did you remember to update your eCos 'malloc heap size'?  This needs
to be done before you build your eCos kernel library.  You'll need to
set the CDL variable as follows:

cdl_option CYGNUM_LIBC_MALLOC_MEMPOOL_SIZE {
    user_value 1638400
};

the value was already set to 1638400 so this is
not the source of my problem.

i wait for Gary's suggestions ;) because i have tried all
that i can.

thanks for your help.

No. This is the CDL description of the C library package and, like the
C library source code, is usually edited only by the package
maintainer. Instead you need to manipulate your specific configuration
and then build eCos accordingly. Under Windows this can be done in the
GUI configuration tool, use the tree view to navigate into the C
library options and then edit the value "Size of the dynamic memory
pool in bytes" to be something appropriate. If instead you are using
the command-line ecosconfig tool, there will be a file ecos.ecc which
you can edit. Somewhere in that file you should see something like:

cdl_option CYGNUM_LIBC_MALLOC_MEMPOOL_SIZE {
    # Flavor: data
    # No user value, uncomment the following line to provide one.
    # user_value 16384
    # Default value: 16384
    ...
}

If you follow the instructions you should end up with something like: 

cdl_option CYGNUM_LIBC_MALLOC_MEMPOOL_SIZE {
    # Flavor: data
    # No user value, uncomment the following line to provide one.
    user_value 1638400
    # Default value: 16384
    ...
}

Then run ecosconfig again to update the build tree, and rebuild eCos.

All this is explained in the eCos User's Guide, which should be part
of your installation. Alternatively, you can read it online at
http://sources.redhat.com/ecos/docs-latest/

to have this make output i change three files :

1. uemf.f to remove this :

//#if LINUX && ! _STRUCT_TIMEVAL
//struct timeval
//{
// time_t tv_sec;  /* Seconds.  */
// time_t tv_usec; /* Microseconds.  */
//};
//#define _STRUCT_TIMEVAL 1
//#endif /* LINUX && ! _STRUCT_TIMEVAL */

2. wsIntrn.h to define WEBS_PAGE_ROM

3. makefile to change "cc" into "gcc" to compile webcomp.c

i don't have a "user_value" but in the stdlib.cdl file i have this :

   cdl_option CYGNUM_LIBC_MALLOC_MEMPOOL_SIZE {
        display       "Size of the dynamic memory pool in bytes"
        flavor        data
        legal_values  32 to 0x7fffffff
        default_value 16384
        description   "
            At this stage, dynamic memory allocation by
            malloc() and calloc() must be from a fixed-size,
            contiguous memory pool (note here that it is the
            pool that is of a fixed size, but malloc() is still
            able to allocate variable sized chunks of memory
            from it). This option is the size
            of that pool, in bytes. Note that not all of
            this is available for programs to
            use - some is needed for internal information
            about memory regions, and some may be lost to
            ensure that memory allocation only returns
            memory aligned on word (or double word)
            boundaries - a very common architecture
            constraint."
    }

is it the "default_value" i must change ?

thanks,

Guillermo.
