hi.
this is my problem :
i write a prog= ram which use raw socket and rteth0 NIC card to send data. when i build&nbs= p; as application it run well. then i build this program as shared libarary= named libctest.so support send() function to send data
the comman= d to build shared lib similar to :

    gcc -shared -Wl,-soname,libc=
test.so.1 -o libctest.so.1.0   *.o
    mv libctest.so.1.0 /opt/lib
  =
  ln -sf /opt/lib/libctest.so.1.0 /opt/lib/libctest.so
    ln -sf /opt/l=
ib/libctest.so.1.0 /opt/lib/libctest.so.1

i write a TEST program = use the send() function which supported by my library.
the command= to build TEST program similar to :

gcc <xenomai options> pro=
g.c -lctest -o TEST

when i execute by command ./TEST
the TEST p= rogram still run. the send() function seem to be right but no data sent to network adapter
