I wish to learn the PcapPlusPlus library in order to manipulate packets. I am using a Cygwin terminal on Windows 10 with all the development tools installed in Cygwin. So, i downloaded the pcapplusplus-20.08-windows-mingw-w64-gcc-8.1.0.zip package of PcapPlusPlus from Github. Then i extracted it and went to the example-app folder. Tried building the app. To do so, I ran the following command:
g++.exe -I C:\Users\home-pc\Desktop\projects\pcapplusplus\header\ -I C:\cygwin64\home\home-pc\WpdPack\Include\ C:\Users\home-pc\Desktop\projects\pcapplusplus\example-app\main.cpp -o C:\Users\home-pc\Desktop\projects\pcapplusplus\example-app\main.exe
Here,
- C:\Users\home-pc\Desktop\projects\pcapplusplus\header\ folder contains header files of PcapPlusPlus
- C:\cygwin64\home\home-pc\WpdPack\Include\ folder contains include header files of WinPcap needed for this tool to work.
When i run this command i get lots of errors. I am new to using C++ libraries. What am i doing wrong here and how to fix it? My errors are as follows:
