fails to cross-build/compile for Windows

[EatThisRock]

When running cmake --build build -t pppwn

I get:

[ 0%] Building CXX object _deps/pcapplusplus-build/Common++/CMakeFiles/Common++.dir/src/GeneralUtils.cpp.obj In file included from :434: :10:9: error: macro name must be an identifier 10 | #define -D_Postinvalid | ^ 1 error generated. gmake[3]: [_deps/pcapplusplus-build/Common++/CMakeFiles/Common++.dir/build.make:77: _deps/pcapplusplus-build/Common++/CMakeFiles/Common++.dir/src/GeneralUtils.cpp.obj] Error 1 gmake[2]: [CMakeFiles/Makefile2:1031: _deps/pcapplusplus-build/Common++/CMakeFiles/Common++.dir/all] Error 2 gmake[1]: [CMakeFiles/Makefile2:402: CMakeFiles/pppwn.dir/rule] Error 2 gmake: [Makefile:182: pppwn] Error 2

Can't seem to find a reason for it?

I am using Ubuntu WSL on Windows 10.

Using Ubuntu WSL, I can compile/build the linux binary and runs just fine.

What commands did you input from the beginning.

[EatThisRock]

If you mean before compiling, I used: cmake -B build -DZIG_TARGET=x86_64-windows-gnu -DUSE_SYSTEM_PCAP=OFF -DPacket_ROOT=/mnt/c/Users/USERNAME/Desktop/PS4/npcap_win_sdk

If it helps I have a log, of the output from this.

[xfangfang]

1. is the version of npcap SDK 1.13?
2. If the build directory was previously used to compile with different cmake option, please delete it and try again
3. Using MSYS2 mingw32/64 to do a native compile
4. Using a real linux or mac to cross compile

You can check the workflow for more information (both mingw and cross compile from linux are contained )

[EatThisRock]

Thanks, I've done 1-2 before. But 3 seems like a good suggestion.

[EatThisRock]

After spending more time into it and given mingw64 was failing elsewhere with no solution in sight, I was able to fix it by adding

#ifndef _Post_invalid_ 
#define _Post_invalid_    
#endif

to Packet32.h from npcap sdk/include folder.

and commented out add_compile_definitions(-D_Post_invalid_=) on CMakeLists.txt, it was able to compile just fine with WSL Ubuntu on Windows 10.

After having npcap installed in windows the compiled binary runs with better success rate than vanilla PPPwn

I am not sure if is the 'right' solution, but is a workaround if anyone is interested.

if cmake >= 3.26 it will remove the leading -D in add_compile_definitions(-D_Post_invalid_=).

So I guess the issue was caused by the cmake version. I just submitted an update, and now it should be possible to compile without modifying the npcap SDK.

Neato, definitely is a better option. Thank you

[oresterosso75]

yet the path is correct! why do I get this error?

`-- Could NOT find Packet (missing: Packet_LIBRARY Packet_INCLUDE_DIR) CMake Error at build/_deps/pcapplusplus-src/CMakeLists.txt:127 (message): Please specify Packet library -DPacket_ROOT=

-- Configuring incomplete, errors occurred!`

You need to provide the environment and cmake command. while referring to the workflow mentioned earlier.

In Linux, you need to pay attention to the issue of path capitalization (which is why workflow modified the path of sdk). The cmake option set for compiling using mingw and cross-compiling in Linux are different (-DPACP_ROOT /-DPacket_ROOT)

[oresterosso75]

@oresterosso75

È necessario fornire l'ambiente e il comando cmake. facendo riferimento al flusso di lavoro menzionato in precedenza.

In Linux, è necessario prestare attenzione al problema della capitalizzazione del percorso (motivo per cui il flusso di lavoro ha modificato il percorso dell'SDK). L'opzione cmake impostata per la compilazione utilizzando mingw e la compilazione incrociata in Linux è diversa (-DPACP_ROOT /-DPacket_ROOT)

Never before have I found myself in difficulty like today, I have truly tried everything. I'm forced to give up

[xfangfang]

@oresterosso75 Providing an error message cannot solve any problem. You need to show what you have done so that others can help you.

example: I am trying to cross compile to Windows under Ubuntu 22.04, using cmake -DPacket_ROOT=... Afterwards, an error occurred, and here is the path to npcap sdk: tree sdk ....

You really need to learn this article: http://catb.org/~esr/faqs/smart-questions.html

[oresterosso75]

@oresterosso75Fornire un messaggio di errore non può risolvere alcun problema. Devi mostrare ciò che hai fatto in modo che gli altri possano aiutarti.

esempio: sto provando a eseguire la compilazione incrociata su Windows con Ubuntu 22.04, utilizzando cmake -DPacket_ROOT=...Afterwards, si è verificato un errore ed ecco il percorso di npcap sdk: tree sdk....

I actually didn't provide much detail about my problem. I apologize for this. to recap, I'm compiling from CMD windows with the following command: cmake -B build -DZIG_TARGET=x86_64-windows-gnu -DUSE_SYSTEM_PCAP=OFF -DPacket_ROOT="C:\PPPwn_cpp-main\npcap-sdk". this is the complete result:

@oresterosso75 As mentioned earlier, either use mingw32/64 for native compilation or cross compile with Linux(macOS, WSL...)

These two compilation methods have been confirmed, you can refer to the workflow.

I haven't tried running cmake directly in CMD for compilation, but it should be a little complex and require manual handling of dependency issues.

Maybe you can try changing the SDK path to: \C:\PPPwn_cpp-main\npcap-sdk or /C:\PPPwn_cpp-main\npcap-sdk
