[TrouSerS-users] cross-compile the trousers (make[2]: *** [libtcs_a-rpc.o] Error 1)

[ytz]

 hi,
I want to cross-compile the trousers-0.3.3.2 :
[r...@happy trousers-0.3.3.2]# sh bootstrap.sh

[r...@happy trousers-0.3.3.2]# ./configure --host=arm-linux 
--with-openssl=/usr/local/openssl 
--prefix=/usr/tss

[r...@happy trousers-0.3.3.2]# make
-MT libtcs_a-rpc.o -MD -MP -MF .deps/libtcs_a-rpc.Tpo -c -o libtcs_a-rpc.o 
`test -f 'rpc/tcstp/rpc.c' || echo './'`rpc/tcstp/rpc.c
rpc/tcstp/rpc.c: In function `recv_from_socket':
rpc/tcstp/rpc.c:62: warning: implicit declaration of function `recv'
rpc/tcstp/rpc.c: In function `send_to_socket':
rpc/tcstp/rpc.c:85: warning: implicit declaration of function `send'
make[2]: *** [libtcs_a-rpc.o] Error 1
make[2]: Leaving directory `/home/ytz/files/trousers-0.3.3.2/src/tcs'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/ytz/files/trousers-0.3.3.2/src'
make: *** [all-recursive] Error 1

although it appears some errors, when I annotate 
~/trousers-0.3.3.2/src/tcs/rpc/tcstp/rpc/tcstp/rpc.c:62 and
~/trousers-0.3.3.2/src/tcs/rpc/tcstp/rpc/tcstp/rpc.c:85
like this:
int
recv_from_socket(int sock, void *buffer, int size)
{
        int recv_size = 0, recv_total = 0;

        while (recv_total < size) {
                errno = 0;
                /*if ((recv_size = recv(sock, buffer+recv_total, 
size-recv_total, 0)) <= 0) {      //line 62
                        if (recv_size < 0) {
                                if (errno == EINTR)
                                        continue;
                                LogError("Socket receive connection error: 
%s.", strerror(errno));
                        } else {
                                LogDebug("Socket connection closed.");
                        }

                        return -1;
                }*/
                recv_total += recv_size;
        }

        return recv_total;
}

int
send_to_socket(int sock, void *buffer, int size)
{
        int send_size = 0, send_total = 0;

        while (send_total < size) {
                /*if ((send_size = send(sock, buffer+send_total, 
size-send_total, 0)) < 0) {         //line 85
                        LogError("Socket send connection error: %s.", 
strerror(errno));
                        return -1;
                }*/
                send_total += send_size;
        }

        return send_total;
}

then it make successfully.

why does it appear the error?

how to resolve it?

Thanks for suggestions.
