Static application missing pcap functionality

[remy06]

Hi,

I have a static application that is missing functionality.

I have managed to build and install Qt ( qt-x11-opensource-src-4.5.0.tar.gz ) on ubuntu 8.04 following this tutorial :
http://wiki.qtcentre.org/index.php?t...ic_Qt_on_Linux

The application is a simple sniffer that uses libpcap .After i build the application with "qmake" and "make", I tested it on another system but the application doesn't seem to capture anything,other functions seem fine. Therefore suspect the problem lies with libpcap.

The following is the steps i used:

1. Install libpcap files with "sudo apt-get install libpcap0.8-dev"
 
2. Building Qt static
 
sudo apt-get install libx11-dev libfreetype6-dev libavahi-gobject-dev libSM-dev libXrender-dev libfontconfig-dev libXext-dev
(* I can only get pass the ./configure step after I've installed the above......)
 
./configure -static -release -nomake demos -nomake examples -nomake tools
make
sudo make install
 
3. Building the application:
 
add to .pro file:
CONFIG += static
LIBS += -L/usr/lib -lpcap
 
export PATH="$PATH:/usr/local/Trolltech/Qt-4.5.0/bin"
qmake
make

1. Install libpcap files with "sudo apt-get install libpcap0.8-dev"

2. Building Qt static

sudo apt-get install libx11-dev libfreetype6-dev libavahi-gobject-dev libSM-dev libXrender-dev libfontconfig-dev libXext-dev
(* I can only get pass the ./configure step after I've installed the above......)

./configure -static -release -nomake demos -nomake examples -nomake tools
make
sudo make install

3. Building the application:

add to .pro file:
CONFIG += static
LIBS += -L/usr/lib -lpcap

export PATH="$PATH:/usr/local/Trolltech/Qt-4.5.0/bin"
qmake
make

everything seems fine..no errors noticed...but I can't figure out what went wrong.....

Is there any solution or something that I've missed?

Please advice...

Maybe the problem is with access right? Did you try running the application as root? Or running it on yet another machine?

Make sure you link your application against libpcap.
