Compilation of libpcap

[Bob Bean]

I am attempting to install the libpcap library
(Version 0.8.3) on my HPUX 11.0 system, and I am running into the following errors, after I run the make. Any suggestions would be appreciated.

Stop.

Bob,

I generally try 'gcc' to compile any GNU related source codes. I have had only few lucks with HP's C compilers.

Which version of libpcap are you trying to compile? I've compiled a number of versions on HP-UX, using the HP compiler, with success. The "inline" warnings are expected.

A bit of find and grep:

find /usr/include -exec grep -l sa_family_t {} \;

suggests that sa_family_t is defined in /usr/include/sys/socket.h, so I would make sure that either pf.h, or the file that includes it includes sys/socket.h. However, that is wrapped with an #ifdef _INCLUDE_XOPEN_SOURCE_EXTENDED

The sa_family_t type is also defined in /usr/include/netinet.in.h, and is wrapped by an #ifdef _XOPEN_SOURCE_EXTENDED.

I cannot recall if those get enabled automagically if you add the -Ae compiler option or not - but you might try settings CFLAGS="-Ae" before you try a fresh configure (make distclean first).

Those include file searches were on my 11.11 system - you might want to verify them on your 11.0 system.

If you were on 11.11, (11i v1) then the "if all else fails" would be to get libpcap from the HP Internet Express bundle. There may also be a pre-compiled libpcap in the HP-UX porting archives.

You can find the latest libpcap sources at http://www.tcpdump.org/

[Bob Bean]

The version I was trying to compile is the latest one (0.8.3)

[Bob Bean]

In the pf.h file, I added the following four lines at the beginning of the file

#ifdef _INCLUDE_XOPEN_SOURCE_EXTENDED
#include "sys/socket.h"
#include "netinet/in.h"
#endif

I also added the CFLAGS="-Ae" to my environment

I then ran make distclean, configure, and then ran the make and received the same errors as before.

[rick jones]

You don't (I think) need to include both inlcude files, and you should't further wrap them with an ifdef. You can try adding a -D_INDLUDE_mumble to CFLAGS on the configure and try again.

You might also consider trying the latest TOT version from tcpdump.org's CVS - a little further down their web page should be a link. I am not certain, but the issue _feel_ familiar and if so, it may be fixed in TOT bits (top of trunk)

I guess then that -Ae is already causing that XOPEN define to be defined.

I _just_ compiled TOT from tcpdump.org on my 11.11 system and it was clean. I don't have any 11.0 systems to check any longer :( So, if you haven't already, try that - pf.h in TOT does not have "sa_family_t" in it to begin with.

Thanks for the help Rick. I pulled the current version from tcpdump.org and it compiled with no problems. I also had to do the same for the tcpdump program as well.
