[ECOS] problems using sockets

[gerardo.rossi@studenti.univr.it]

We are two italian students, for our thesis we use an application that has need
to use the sockets under eCos, we shape eCos with the following configuration:

Using Configtool:

in Build->Templates we select

hardware: "Linux Synthetic Target"

template: "net", that includes all these packages:

    package -hardware CYGPKG_HAL_SYNTH v2_0 ;
    package -hardware CYGPKG_HAL_SYNTH_I386 v2_0 ;
    package -hardware CYGPKG_DEVS_FLASH_SYNTH v2_0 ;
    package -hardware CYGPKG_DEVS_ETH_ECOSYNTH v2_0 ;
    package -hardware CYGPKG_DEVS_WATCHDOG_SYNTH v2_0 ;
    package CYGPKG_HAL v2_0 ;
    package CYGPKG_IO v2_0 ;
    package CYGPKG_IO_SERIAL v2_0 ;
    package CYGPKG_INFRA v2_0 ;
    package CYGPKG_ISOINFRA v2_0 ;
    package CYGPKG_KERNEL v2_0 ;
    package CYGPKG_MEMALLOC v2_0 ;
    package CYGPKG_LIBC v2_0 ;
    package CYGPKG_LIBC_TIME v2_0 ;
    package CYGPKG_LIBC_STDLIB v2_0 ;
    package CYGPKG_LIBC_STRING v2_0 ;
    package CYGPKG_LIBC_I18N v2_0 ;
    package CYGPKG_LIBC_SETJMP v2_0 ;
    package CYGPKG_LIBC_STARTUP v2_0 ;
    package CYGPKG_LIBC_STDIO v2_0 ;
    package CYGPKG_LIBM v2_0 ;
    package CYGPKG_POSIX v2_0 ;
    package CYGPKG_IO_WATCHDOG v2_0 ;
    package CYGPKG_IO_WALLCLOCK v2_0 ;
    package -template CYGPKG_ERROR v2_0 ;
    package -template CYGPKG_IO_FILEIO v2_0 ;
    package -template CYGPKG_NET v2_0 ;
    package -template CYGPKG_NET_FREEBSD_STACK v2_0 ;
    package -template CYGPKG_NS_DNS v2_0 ;
    package -template CYGPKG_IO_ETH_DRIVERS v2_0 ;

... so we compile eCos(Build->Library) and our application "app_adpcm.c"
obtaining this error:

gcc -c -o app_adpcm.o -I/home/rossi/ecos/ecos-work/net_install/include -Wall
-Wpointer-arith -Wstrict-prototypes -Winline -Wundef -Woverloaded-virtual -g

collect2: ld returned 1 exit status
make: *** [app_adpcm] Error 1


NOTE: we obtain this error also compiling the eCos examples, but using template
"default" is all ok.

PLEASE WE NEED HELP TO MORE SOON !! THANKS!
