libpcap was just upgraded to 0.9.8, should be available within 12 hours via 'port sync' (or 'port selfupdate'). Compiles fine for me on 10.5.1 x86, please test and re-open the ticket if you still have problems.

Did the "port selfupdate", but 0.9.8 still fails:

Okay, time for more information. What OS rev, what hardware (PPC vs x86), etc.? Do you have fink installed? Anything in /usr/local? Any other custom stuff installed?

comment:6 Changed 13 years ago by albatros@…

MacBook Pro, i.e. C2D "Santa Rosa", 2.4 GHz, 4 GB.

10.5.1 (fresh installation of 10.5, then upgrade)

No "weirdies" installed, apart from VMware (which has some kexts), no fink.

MacPorts installed in /opt/macports-1.6.0

There's an ssh in /usr/local, and an streplace.

Seeing that there's a problem with lex: lex is /usr/bin/lex, flex is /opt/macports-1.6.0/bin/flex...

From which place should the undefined symbols be normally picked up?

comment:9 Changed 13 years ago by albatros@…

Btw, here are lines 84ff from scanner.l, i.e. where the first error occurs (that then seem to trigger the linker errors -- the Makefile doesn't seem to be too bright: it shouldn't attempt to link after such an error in the first place).

%a 18400
%o 21500
%e 7600
%k 4550
%p 27600
%n 2000

And the first lines of error from flex, when running "make" manually.

flex -Ppcap_ -t scanner.l > $$.scanner.c; mv $$.scanner.c scanner.c
scanner.l:84: bad character: %
scanner.l:84: unknown error processing section 1
scanner.l:84: unknown error processing section 1
scanner.l:84: bad character: 1
...

comment:10 Changed 13 years ago by albatros@…

Getting impatient I simply removed the offending lines from scanner.l, which made the compile work, and now I'm running tcpdump and wireshark; who knows whether/when/how it will bite me in the future? ;-)

comment:11 Changed 13 years ago by ghosthound

libpcap appears to fail w/ MP-installed 'flex', works fine with /usr/bin/flex. I'll see if I can convince it to use the system installed flex, in the meantime you can reset your path to have '/usr/bin' before the macports bin directory.

comment:12 Changed 13 years ago by danielluke (Daniel J. Luke)

macports doesn't use the user's path when building stuff (it uses its own sanitized path).

The temporary workaround would be to deactivate flex, build it, and then reactivate flex.

comment:13 Changed 13 years ago by ghosthound

Ha! Lookie that, so it does (use its own path when building). Learn something every day :)

Hmm,for Stefmit - can you try 'sudo port -f -v -d build libpcap'? It builds for me after I deactivate flex.... (on 10.5.1, x86)

Noah reported the same problem on macports-users again.

comment:15 Changed 13 years ago by catchmonster@…

deactivating flex and port clean libpcap; port build libpcap; port install libpcap worked for me.

This is a bug introduced in the last update of flex (2.5.34). See the bug report at the sourceforge page: http://sourceforge.net/tracker/index.php?func=detail&aid=1860773&group_id=97492&atid=618177

As the flex parser ignores the % statements, here is a patch file for libpcap which removes the offending parts.

patch tested with and without MP-installed flex (on leopard x86), libpcap builds either way. patch committed in r34191. Thanks much!
