Errors building libdnet for x64 and python 2.7

[newlog]

Hello,

First of all, thanks for creating this fork. I've ended here after having to fight with the "WARNING: No match between your pcap and dnet network interfaces found." error without success.

So I've tried to build your fork in my Windows 8.1 x64 machine with Python 2.7. I've had a lot of problems and I'd be really grateful if you could help me.

These are the steps I've followed:

1. I've cloned you repository and executed the autogen.sh script inside Cygwin, having MinGW also installed.
   This gave me a lot of trouble, basically for using libtool from MinGW instead of the one from Cygwin. So I uninstalled the one from MinGW and installed the one from Cygwin. After this, the autogen.sh worked and the configure file was created.
2. I executed ./configure and failed when checking for Python, it seemed a MinGW32 issue. So I installed a bunch of MinGW packages of 32 bits such as headers and so. Don't know exactly how, but this solved the problem.
   Nevertheless, the ./configure failed again. Now the problem was because of winpcap developer library not found. So I executed configure as:
   ./configure --with-wpdpack=<path_to_lib>
3. Then I cd python and executed /c/cygdrive/python2.7/python.exe setup.py build and got this error:

$ /cygdrive/c/Python27/python.exe setup.py build
running build
running build_ext
building 'dnet' extension
error: Unable to find vcvarsall.bat

First real unsolved problem here. So instead of using OS python.exe I've also tried to use cygwin python. I got this error:

$ /usr/bin/python2.7 setup.py build
running build
running build_ext

 #include "Python.h"
                    ^

Seems that Python.h is not found, although it's in the /usr/include/Python2.7 folder. I've added it to PATH with export PATH="$PATH:/usr/include/python2.7" but it gave the same error.

Then I came back to the Unable to find vcvarsall.bat error. Still from cygwin I executed:

$ export DISTUTILS_USE_SDK=1
$ export MSSdk=1
$ /cygdrive/c/Python27/python.exe setup.py build

cl.exe /c /nologo /Ox /MD /W3 /GS- /DNDEBUG -I../include -I../../WPdpack/Include -IC:\Python27\include -IC:\Python27\PC /Tc./dnet.c /Fobuild\temp.win-amd64-2.7\Release\./dnet.obj
error: command 'cl.exe' failed: No such file or directory

Ok, this problem about not locating 'cl.exe' is because if you use the OS python.exe and you have not built it, the compiler that was used to build it is used to build the python extension. I've tried to add the location of cl.exe folder in path (export PATH="$PATH:/cygwin/c/Program Files (x86)/Microsoft Visual Studio 12.0/VC/bin/x86_amd64"), but it didn't work.So...

Next step was to open Visual C++ 2008 64-bits Command Prompt so cl.exe is easily found. I exported the symbols mentioned before and executed:

error: command 'C:\\Users\\windows8\\AppData\\Local\\Programs\\Common\\Microsoft\\Visual C++ for Python\\9.0\\VC\\Bin\\amd64\\cl.exe' failed with exit status 2

This is the REAL problem. It seems that python already defines the ssize_t type in pyconfig.h. I could remove declarations or make them match. The best approach was to make them match types (modifying __int64 for long) by modifying line 199 of pyconfig.h:

#ifdef MS_WIN64
typedef long ssize_t;
#else
typedef _W64 int ssize_t;
#endif

This solved the problem of redefinitions, but still remained the fatal error C1083: Cannot open include file: 'stdint.h': No such file or directory.

I've tried to comment this includes in os.h and intf.h, but it ended up giving me this error after a large number of warnings:

I realised that the lack of stdint.h was because of Microsoft VC 2008 didn't supported some C99 features, so I tried with VC 2013. After removing comments from the stdint.h includes (I also could remove the modification of pyconfig.h) I executed the same command from the Developer Command Prompt for VS 2013 and got the following (complete) output:

Seems that the problem is that size_t is already defined as int so the following code in crtdefs.h fails:

#ifndef _SIZE_T_DEFINED
#ifdef _WIN64
typedef unsigned __int64    size_t;
#else  /* _WIN64 */
typedef _W64 unsigned int   size_t;      <--
#endif  /* _WIN64 */
#define _SIZE_T_DEFINED
#endif  /* _SIZE_T_DEFINED */

It seems that there's again a redefinition. I've found it in libdnet source at include/config.h in line 270:

/* Define to `unsigned int' if <sys/types.h> does not define. */
//#define size_t unsigned int

After commenting it, the build process has continued with a lot of warnings until this error:

Given that the libdnet doesn't have any pcap.h file, I guess that this file must refer to the winpcap development library. So I try to add the correct directory to the INCLUDE environment variable with set INCLUDE=%INCLUDE%;<path_to_winpcap_dev>\WpdPack_4_1_2\WpdPack\Include

There are two pcap.h files. One in the Include directory and another in the Include\pcap directory. I've tried to add both of them in the INCLUDE environment, but neither worked. I finally got a long list of new errors:

So I'm stuck here and I don't know what else to do. This is a nightmare, guys. How could you build this? I'm defeated....

Thank you very much for reading until here.

I've been able to compile this beast in very similar environment.
I'll try to describe the details later, but there are the following key points:

• code can't be compiled on Microsoft Python Visual Studio 9, as recommened in all places - there's no stdint.h
• distutils import in setup.py(.in) shall be replaced with setuptools - the same API, much better handling of vcvarsall.bat
• source has to be fixed - intf-win32.c - added MAX_LEN define and added declarations of some vars in the beginning of some function instead of the middle to make compiler happy

I haven't verified the executable yet.
I'll have to clean up all artifcacts and provide clean instruction. Hopefully they can be turned into valid pull requests.

[rgom]

For the time being I'm posting the exact steps. I hope I'll send patches later on.

1. Build

   • Install cygwin build tools (autoconf, automake, libtool)

   • start cmd

   • run "c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat" (VC 10)

   • run c:\cygwin\cygwin.bat

   • run ./autogen.sh

   • run ./configure --with-wpdpack=c:/temp/scapy-new/WpdPack

   • Modify setup.py

     #from distutils.core import setup, Extension
     from setuptools import setup, Extension
     

     and this

       # ROGO - below line modified to contain wpcap
       dnet_libs.extend([ 'advapi32', 'iphlpapi', 'ws2_32', 'packet', 'wpcap' ])
     

   • modify sources

       /* (intf-win32.c) */
     IP_ADAPTER_UNICAST_ADDRESS *addr;
     char friendly_name[MAX_INTERFACE_NAME_LEN];
     const char *name_start;
     /* The total length of the entry may be passed inside entry.
        Remember it and clear the entry. */
     u_int intf_len = entry->intf_len;
     memset(entry, 0, sizeof(*entry));
     entry->intf_len = intf_len;
     
     type = _if_type_canonicalize(a->IfType);
     for (i = 0; i < intf->ifcombo[type].cnt; i++) {
     if (intf->ifcombo[type].idx[i].ipv4 == a->IfIndex &&
         intf->ifcombo[type].idx[i].ipv6 == a->Ipv6IfIndex) {
         break;
     }
     }
     /* XXX - type matches MIB-II ifType. */
     snprintf(entry->intf_name, sizeof(entry->intf_name), "%s%lu",
     _ifcombo_name(a->IfType), i);
     entry->intf_type = (uint16_t)type;
     strncpy_wchar(friendly_name, a->FriendlyName, MAX_INTERFACE_NAME_LEN);
     snprintf(entry->os_intf_name, MAX_INTERFACE_NAME_LEN, "%s %s", friendly_name,
     a->AdapterName);
     entry->os_intf_name[MAX_INTERFACE_NAME_LEN - 1] = '\0';
     
     name_start = strstr(a->AdapterName, "{");
     if (name_start) {
     snprintf(entry->pcap_intf_name, MAX_INTERFACE_NAME_LEN - 1,
         "\\Device\\NPF_%s", name_start);
     }
     

     and add to the top:

     #define MAX_INTERFACE_NAME_LEN 255
     

   • quit cygwin with exit

   • python setup.py build --compiler=msvc

   • python setup.py bdist_wheel

Notes:

1. Don't use mingw
2. The following wouldn't work - there's no stdint.h in MSVC9:
   Install Python 2.7 MS visual from http://aka.ms/vcpython27 (http://www.microsoft.com/en-us/download/details.aspx?id=44266)
   (http://blog.ionelmc.ro/2014/12/21/compiling-python-extensions-on-windows/)
   I've used MSVC 10

[rgom]

Despite compiling it successfully 1.13 seems to be broken.
There were numerous changes pulled in (e.g. from nmap), at least one of them broke get_dst() (intf-win32), which is now just unsupported (https://github.com/nmap/nmap/tree/master/libdnet-stripped)
Add to the above fact that the code required modifications in order to become compilable, it's status on win32 is poor.

I'll look into fixing things, but that will take several weeks/months.

Regards,
Robert

I have successfully built libdnet using the instructions and patches given by @rgom above. The patched Scapy can send and receive packets (e.g. its traceroute command works).

• If configure tells you no acceptable ld found in $PATH, install the binutils package via Cygwin
• The patch command is part of the patch package in Cygwin
• I had to pass the --ignore-whitespace option to the patch command to make the patches apply
• On my 32bit system I got a misleading configure error: need MingW32 package to build under Cygwin. This went away after I added || test "$MINGW" = no to the if condition on line 85 of configure.ac and ran autogen.sh again.
• For pyrex I used the binary installer from http://brl.thefreecat.org/python-pyrex/Pyrex-0.9.9.win32.exe
• Binary Windows installers can be created by using python setup.py build bdist_wininst.

[rgom]

Ah, that makes sense now.
I must have kept some cygwin packages installed in the past (mingw*).
And yes, I've forgotten about some other build dependencies in the description above for the same reason.
You're right that configure/autogen additional modifications are necessary.

Best regards,
Robert

Ok, forked the repo and created first of pull requests.
Let's see how well it goes - this is the easiest one, some of later patches will cause API incompatibility (some function arguments in pyx were named after Python reserved words).
That might require further discussion and even version change.
I'll see how responsive is upstream.

Robert

[rgom]

There's a possibility to simplify the patches a bit:

• type -> typee change seems unnecessary (can be done another way)
• distutils -> setuptools in scapy is needed only when trying to create wheels (as I want) - otherwise (even for bdist_wininst) distutils is fine (no setup.py changes required)

I'll try to update the patches next days.
(Pull requests already submitted for scapy and dnet still require merging - they are fine by themselves)

Robert

[rgom]

Ok, here it comes.
I'll post updated dnet and scapy patches here with added comments.
Patches will be split.

1. Dnet:

And now corresponding scapy part:

(This is big, sorry for that).
windows/init.py changes:

• fix getting pcap device name (avoid names mismatch between pcap and dnet)
• raise exceptions when giving invalid interfaces names (instead of using default names in such cases)
• (unrelated, but I needed this) use readline only in interactive mode. When using non-interactively it caused problems e.g. with Pydev
• (unrelated, but I needed this) merge and enhance stop_filter from non-win32 sniff() implementation to allow conditional sniff stop
