I installed pcapplusplus on Ubuntu (Downloaded package from here: https://github.com/seladb/PcapPlusPlus/releases/tag/v21.11). The example that was in the archive compiles and works, everything is fine with it! But when I try to include the library in my project using CMake nothing works.
I write a line in CMakeLists.txt file:
include_directories("/usr/local/include/pcapplusplus")
After that, the header files are connected to the project. However, the project does not compile, various errors appear depending on the functions that I use. Most likely the linker does not see the files: libCommon++.a, libPacket++.a, and libPcap++.a. I tried to connect them like this:
target_link_libraries(${PROJECT_NAME} libCommon++.a libPacket++.a libPcap++.a)
But it did not help. Tried this:
find_package(pcapplusplus REQUIRED)
include_directories(${PCAPPLUSPLUS_INCLUDE_DIRS})
This didn't help either.
In fact, other people have already encountered such a problem, for example, netleap tom wrote about this on the StackOverflow. cmake linking against static libraries - do you have to tell cmake where to look? However, no one there suggested a solution to him. I hope someone will tell me what to do.

Hello World from here for example:
#include <IPv4Layer.h>
#include <Packet.h>
#include <PcapFileDevice.h>
int main(int argc, char* argv[])
{
pcpp::PcapFileReaderDevice reader("1_packet.pcap");
if (!reader.open())
{
printf("Error opening the pcap file\n");
return 1;
}
pcpp::RawPacket rawPacket;
if (!reader.getNextPacket(rawPacket))
{
printf("Couldn't read the first packet in the file\n");
return 1;
}
if (parsedPacket.isPacketOfType(pcpp::IPv4))
{
pcpp::IPv4Address srcIP = parsedPacket.getLayerOfType<pcpp::IPv4Layer>()->getSrcIpAddress();
pcpp::IPv4Address destIP = parsedPacket.getLayerOfType<pcpp::IPv4Layer>()->getDstIpAddress();
printf("Source IP is '%s'; Dest IP is '%s'\n", srcIP.toString().c_str(), destIP.toString().c_str());
}
reader.close();
return 0;
}
If I add only this to CMake:
include_directories("/usr/local/include/pcapplusplus")
I have the following errors:
