Hi --
htons, ntohs, htonl, and ntohl on Linux platforms are implemented as a
"statement expression", which is a gcc extension. It seems Intel compilers
(icc) currently do not support this. You will have to wait for the Intel
compilers to have this support. Until then you can have a temporary
workaround for this problem as follows:
Put the following after the #include of in.h (in socket.c and
share/ssi/boot/base/ssi_boot_server.c)
#if defined(__ICC)
// icc doesn't like GNU __extension__ functions
// this has to happen AFTER !!
#undef htons
#undef ntohs
#undef htonl
#undef ntohl
#define htons(x) __bswap_constant_16(x)
#define ntohs(x) __bswap_constant_16(x)
#define htonl(x) __bswap_constant_32(x)
#define ntohl(x) __bswap_constant_32(x)
#endif // defined(_ICC)
