I am attempting to compile iftop 0.17 on an HP Integrity (i.e., IA64) server under HP-UX 11.23. I am using the following GNU build environment:

ar : GNU ar 2.17 as : GNU assembler 2.17 autoconf : autoconf (GNU Autoconf) 2.61 automake : automake (GNU automake) 1.10 bison : bison (GNU Bison) 2.3 flex : flex 2.5.33 gawk : GNU Awk 3.1.5 gcc : gcc (GCC) 4.1.2 make : GNU Make 3.81 nm : GNU nm 2.17 sed : GNU sed version 4.1.5 shtool : GNU shtool 2.0.7 (19-May-2007)

And, the following configure command:

CFLAGS='-lpthread' CPPFLAGS='-I /usr/local/include/ncurses' CC=gcc ./configure

The CFLAGS parameter is required to overcome an error in configure, to correctly identify the threads capability in HP-UX.

The CPPFLAGS parameter is required to overcome an error in make, to correctly located the ncurses library.

The command results in the following make error:

source='addrs_dlpi.c' object='addrs_dlpi.o' libtool=no \ depfile='.deps/addrs_dlpi.Po' tmpdepfile='.deps/addrs_dlpi.TPo' \ depmode=gcc3 /bin/sh ./config/depcomp \ gcc -DHAVE_CONFIG_H -I. -I. -I. -I /usr/local/include/ncurses -lpthread -c `test -f 'addrs_dlpi.c' || echo './'`a ddrs_dlpi.c addrs_dlpi.c:24:24: error: sys/sockio.h: No such file or directory addrs_dlpi.c:53: warning: 'struct in_addr' declared inside parameter list addrs_dlpi.c:53: warning: its scope is only this definition or declaration, which is probably not what you want addrs_dlpi.c: In function 'get_addrs_dlpi': addrs_dlpi.c:184: error: dereferencing pointer to incomplete type addrs_dlpi.c:190: error: dereferencing pointer to incomplete type addrs_dlpi.c:190: error: invalid application of 'sizeof' to incomplete type 'struct in_addr' make[2]: *** [addrs_dlpi.o] Error 1 make[2]: Leaving directory `/usr/local/install/iftop-0.17' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/local/install/iftop-0.17' make: *** [all] Error 2 #

The first error, regarding the 'sys/sockio.h' header can be overcome by removing the include from the addrs_dlpi.c source, since, according to HP, the socket ioctl definitions are defined in the /usr/include/sys/ioctl.h' header file, which is included in the addrs_dlpi.c source. However, removing the 'sys/sockio.h' reference only resolves the first error; the other errors, regarding the pointer dereferencing and the type application remain.

The section of addrs_dlpi.c code apparently generating the errors looks like:

178 #ifdef SIOCGIFADDR 179 180 fd = socket(PF_INET, SOCK_DGRAM, 0); /* any sort of IP socket will do */ 181 182 strncpy(ifr.ifr_name, interface, IFNAMSIZ); 183 184 (*(struct sockaddr_in *) &ifr.ifr_addr).sin_family = AF_INET; 185 186 if (ioctl(fd, SIOCGIFADDR, &ifr) < 0) { 187 fprintf(stderr, "Error getting IP address for interface: %s\n", "ge0"); 188 perror("ioctl(SIOCGIFADDR)"); 189 } else { 190 memcpy(if_ip_addr, &((*(struct sockaddr_in *) &ifr.ifr_addr).sin_addr), sizeof(struct in_addr)); 191 got_ip_addr = 2; 192 } 193 #else 194 fprintf(stderr, "Cannot obtain IP address on this platform\n"); 195 #endif

Although the warnings appear to reference the structure definition generating the errors:

51 52 int 53 get_addrs_dlpi(char *interface, char if_hw_addr[], struct in_addr *if_ip_addr) 54 { 55 int got_hw_addr = 0; 56 int got_ip_addr = 0; 57

Any ideas as to where to go next? Any help would be appreciated. Thanks.
