It seams like the linker couldn't find the pcap library.
Have you set the LIB in your qmake correct?
INCLUDEPATH += c:/pcap/include
LIBS += -L c:/pcap/Lib -lwpcap ....
Thanks for your response dear hpollak.
I installed both mcvs-opengl 32bit & 64bit.
i can solve these errors for 32bit (By declartion non-static variable !!! )
how can i solve these similar errors for x64.
Also, I've added INCLUDEPATH & LIBS but the errors are shown.
finally i could solve one of my problem!
if you use winpcap in your program, you must add -lwsock32 in LIBS to your .pro file. like this:
LIBS += -LC:/WpdPack/Lib -lwpcap -lpacket -lwsock32
