error: dereferencing pointer to incomplete type in solaris x86 about pypcap HOT 14 CLOSED

what version of libpcap do you have installed? it looks like a missing 
pcap-int.h
header file.

can you show me the output for these commands?

   cat config.h

and in python:

>>> import cPickle
>>> cPickle.loads(open('config.pkl').read())

thank you for your kind and quick comment, dugsong :0

i `v installed libpcap version 0.9.5.
there is no pcap-int.h in this version.
config.pkl
there `s no config.h or config.pkl too.
i have to go back libpcap version  with pcap-int.h?
for example libpcap version 0.7.1.

sorry dugsong,
i brought compiled binary version libpcap from sunfreeware.
but there "IS" definetely pcap-int.h in libpcap 0.9.5 source from tcpdump.org.
i`m lazy.very soory for that.

only after in the source directory do "gmake" ,cconfig.h or config.pkl came 
into view.

[07:16:04 sandy@gagemel pypcap-1.1]$ more config.h

and finally got pcap.so.only after " do gmake",everything goes

** final comment.
i`v copied pcap-int.h file from libpcap 0.9.5 source to /usr/local/include .
because gmake install only copied pcap.h,pcap-bpf.h,pcap-namedb.h.

ㅠㅠ . maybe there are some problems in compiled  pcap.so.

dugsong!!

in my ubuntu box, there is same error.
so using Pyrex, fixed pcap.pyx.

pyrexc pcap.pyx
python setup.py build.

after that, nothing wrong happen.everything goes well.

but back to solaris box, that fix doesn`t work.

using Pyrex, fix pcap.pyx.
this is last solution.maybe.
on my solaris box , this fix worked.
thanks, dugsong.

yes, you have to 'make' or 'gmake' in order for 'python setup.py config' to be
executed. i should probably change this. :-(

the missing pcap-int.h in comment #6 can be worked around by modifying 
CONFIG_ARGS in
the Makefile to point to your libpcap build directory, instead of using an 
installed
version.

the missing bpf_filter symbol in comment #7 and #8 i don't understand - and i 
don't
understand how regenerating the pcap.c source using pyrex in comment #9 and #10 
would
have fixed it. but if it works, that's great! :-)

can you mail me your regenerated pcap.c file so i can compare? also, what 
version of
Pyrex are you using? i don't have access to a Solaris 10 x86 box right now, so i
cannot reproduce this easily.

thank you!

i`m very sorry about symbol error in comment #7 and #8.
that was my ld setting error.i used /usr/ccs/bin/ld in error situation.
whem i use gnu ld , erorr message has gone. :)

well working pcap module.

great!

i upgraded to Pyrex-0.9.5.1a and regenerated pcap.c for the package, and added 
a note
to the README about the build. sorry for any confusion.

the fix is in svn, and i'll cut a new version later, after some additional 
changes go
in...
