ld: cannot find -lpcap

Trying to compile dnstop:

Using gcc version 3.3.2

I installed these first:
libpcap-0.8.1-sd-11.00.depot
tcpdump-3.8.1-sd-11.00.depot
bison-1.875-sd-11.00.depot
flex-2.5.4a-sd-11.00.depot

I try make all from

/usr/local/src/dnstop-20040309

gcc -g -Wall -I/usr/local/include -I/usr/local/lib -o dnstop dnstop.o -lpcap -lcurses
/opt/pa20_64/bin/../lib/gcc-lib/hppa64-hp-hpux11.11/3.3.2/../../../../hppa64-hp-hpux11.11/bin/ld: cannot find -lpcap
collect2: ld returned 1 exit status
*** Error exit code 1

Stop.

I'm compiling as root on HP-UX 11.11.

Thanks...Geoff

I would take the box at its word. Either install libpcap or alter the linker's library search path to include the location of your libpcap file. It's also possible that libpcap isn't even needed so youi could try altering the makefile to remove the -lpcap statement. -lpcap is linker shorthand for libpcap.a or libpcap.sl in the directories specifed by the linkers library search path.

http://hpux.connect.org.uk/hppd/hpux/Networking/Admin/libpcap-0.8.1/

[Geoff Wild]

Yes, I did install libpcap...

I had to add -I/usr/local/include -I/usr/local/lib to the CFLAGS for it to see pcap.h and pcap-bpf.h

libpcap.a and libpcap.sl are in /usr/local/lib/

Rgds...Geoff

[Geoff Wild]

Okay - getting somewhere:

# export LPATH=/usr/local/lib:/usr/lib
# make all

[H.Merijn Brand (procura]

you do not by accident run a 64bit gcc, now do you?

Hmm, I guess you do.
Make your life easier and rename is to gcc64

64bit objects do NOT mix with 32bit objects

all objects (including crt0.o) in /usr/lib are 32 bit
64bit objects are in /usr/lib/pa20_64

Enjoy, Have FUN! H.Merijn

[Geoff Wild]

Ah ha - Merijn - I do:

# which gcc
/opt/pa20_64/bin/gcc


So I tried:

export LPATH=/usr/local/lib

Now I get:

Ok - started over - removed my gcc 2.9.5 and installed:

http://hpux.ee.ualberta.ca/hppd/hpux/Gnu/gcc-3.3.2/

The Makefile is default except for CC=/usr/local/bin/gcc

Any ideas?

Thanks...Geoff

[Geoff Wild]

Getting closer:

# make all
/usr/local/bin/gcc -g -Wall -c dnstop.c
In file included from dnstop.c:29:
/usr/include/sys/socket.h:484: parse error before "sendfile"

dnstop.c: In function `StringCounter_report':
dnstop.c:751: warning: implicit declaration of function `getmaxy'

Stop.


Here's the function:
StringCounter_report(StringCounter * list, char *what)
{
StringCounter *sc;
int nlines = getmaxy(w) - 6;
printw("%-20s %9s %6s\n", what, "count", "%");
printw("%-20s %9s %6s\n",
"--------------------", "---------", "------");
for (sc = list; sc; sc = sc->next) {
printw("%-20.20s %9d %6.1f\n",
sc->s,
sc->count,
100.0 * sc->count / query_count_total);
if (0 == --nlines)
break;
}
}

I don't use the Gnu compilers but based upon your last error, I would say that you need to add
#include

to your source file or include it in a header file before socket.h. NOTE: some typedefs are controlled by #ifdef's so that you may need to assert some defines in your makefile.

[Geoff Wild]

Thanks Clay - here's all the includes in dnstop.c:

#include

If you look in /usr/include/sys/socket.h at line 484 you will find a reference to a sbsize_t type. This is defined in /usr/include/sys/types.h. While this header file is included in your source file, the definition of sbsize_t or even the lack thereof is determined by some pre-processor #ifdef's and if defined()'s. You need to examine, sys/types.h to see which symbols you need to define and alter your makefile accordingly.

[Geoff Wild]

Okay - I give up - if anyone wants to take a crack at compiling dnstop, go for it. If successful, please post here how you did it.

Thanks...Geoff

[H.Merijn Brand (procura]

10 minutes :)

where do you want to have it?

Enjoy, Have FUN! H.Merijn

[Geoff Wild]

Merijn Wow!

Did you use gcc or HP?

How about on your site?
http://www.cmve.net/~merijn/

Thanks...Geoff

[H.Merijn Brand (procura · Accepted solution]

I used gcc, because that's what the Makefile said :)

I added two include directories to CFLAGS (-I...)
I added to lib search path's to ld (-L...)
I added -statc to load, so I don't have to supply libpcap.sl and libncurses.sl

I changed #include to #include and -lcurses to -lncurses because curses doesn't know about getmaxy ()

Phrrrt. writing these posts took longer than building the stuff :]

Enjoy, Have FUN! H.Merijn

[Geoff Wild]

Thanks Merijn!

I'd still like to compile myself - almost got it working...did the same as you....had to add:

#ifndef _BSIZE32_T
# define _BSIZE32_T
typedef int32_t sbsize32_t;
typedef uint32_t bsize32_t;
#endif
#ifndef _BSIZE64_T
# define _BSIZE64_T
# if !defined(__STDC_32_MODE__)
typedef int64_t sbsize64_t;
typedef uint64_t bsize64_t;
# endif
#endif
#ifndef _BSIZE_T
# define _BSIZE_T
# if defined(_APP32_64BIT_OFF_T) || defined(_KERNEL)
typedef int64_t sbsize_t;
typedef uint64_t bsize_t;
# else
typedef long sbsize_t;
typedef unsigned long bsize_t;
# endif
#endif

To bottom of /usr/local/lib/gcc-lib/hppa2.0n-hp-hpux11.00/3.2/include/sys/types.h before the last #endif

Now I get:

# gmake all

[H.Merijn Brand (procura]

add -lc_r or -ldld

these symbols are in /usr/lib/dld.sl, libdld.sl, and libc_r.sl (the reentrant version of libc)

Enjoy, Have FUN! H.Merijn

[Geoff Wild]

Merijn - done!

Had to do it like this:

CFLAGS=-g -Wall -l:libdld.sl -I/usr/local/include

Otherwise I got
/usr/bin/ld: Can't find library: "dld"

Thanks for all your help.
