libpcap help

[Pordo]

hello, I am trying to install the pcap library in Qt but I am having problems. Try to add the path with

INCLUDEPATH += C:\Users\Usuario\Desktop\Lucas Pordomingo\recibir_paquete\libpcap-1.10.1

but I get the error: :-1: error: cannot find -lpcap

I don't know how to fix this. This is the version of Npcap 1.10.1 I used:

@Pordo
You have changed INCLUDEPATH, which is for searching for #include .h files. Your error is for the -lpcap argument to the linker. You need to do something about adding that path to the LIBS variable.

[Pordo]

I put this:
INCLUDEPATH += C:\Users\lucas\Desktop\Nueva carpeta\recibir_paquete\WpdPack\Include
LIBS += "-LC:\Users\lucas\Desktop\Nueva carpeta\recibir_paquete\WpdPack\Lib" -lwpcap -lpacket
LIBS += -lws2_32

DEFINES += WPCAP
DEFINES += HAVE_REMOTE

and then:
#include <pcap.h>

but I hace the error:

C:\Users\lucas\Desktop\Nueva carpeta\recibir_paquete\main.cpp:18: error: pcap.h: No such file or directory
..\recibir_paquete\main.cpp:18:10: fatal error: pcap.h: No such file or directory

but...the file pcap.h is in this path
INCLUDEPATH += C:\Users\lucas\Desktop\Nueva carpeta\recibir_paquete\WpdPack\Include

Hi,

Did you forgot to quote the path that contains spaces ?

[JonB]

@Pordo
As @SGaist has written: you correctly quote the path with a space in the LIBS line but not in the INCLUDEPATH line. I did not notice that in your first post.

[Pordo]

I do not know what you mean with that exactly, the folder moved it from place but I still have the same error, now I have it in :

INCLUDEPATH += C:\Users\lucas\Desktop\paquetes\WpdPack\Include
LIBS += "-LC:\Users\lucas\Desktop\paquetes\WpdPack\Lib"-lwpcap -lpacket
LIBS += -lws2_32

DEFINES += WPCAP
DEFINES += HAVE_REMOTE

I do not know what is the quote I have to put

[JonB]

@Pordo

but I still have the same error

Now that you have removed space from the path (and hence quoting is not an issue) I do not believe you are receiving the same error message, so show what it is now.

[Pordo]

It show me this error:

C:\Users\lucas\Desktop\paquete\main.cpp:16: error: pcap.h: No such file or directory
....\paquete\main.cpp:16:10: fatal error: pcap.h: No such file or directory
16 | #include <pcap.h>
| ^~~~~~~~

Im using the Qt 6.3.1 MinGW 64-bit version, and for pcap the version Winpacp 4.1.2 I don't know if it has something to do with it

Open your Makefile in the build dir and post this line here
INCPATH =

@Pordo

INCLUDEPATH += C:\Users\lucas\Desktop\paquetes\WpdPack\Include

C:\Users\lucas\Desktop\paquete\main.cpp:16: error: pcap.h: No such file or directory

How are these related? What is the full path to your pcap.h file?
