Install pypcap on Windows 10 python 2.7 (64 bit)

I am trying to install pypcap from: https://github.com/dugsong/pypcap/blob/master/INSTALL#L75

I am trying to install it on Windows 10 - 64 bit and python 2.7.11 64 bit. I downloaded the source and move it to the c:\pypcap . downloaded pyrex and installed it as well. It puts wpdpack files in c:\wpdpack , as the installation page says. Created a configuration file and changed the make file.

I also installed mingw from my site with the base package and g++ package.

I am trying to do:

 C:\pypcap> set PATH=%PATH%;c:\MinGW\bin;c:\Python27 C:\pypcap> mingw32-make

and here it fails, it gets the following error:

 In file included from C:\Python27\include/Python.h:8:0, from pcap.c:4: C:\Python27\include/pyconfig.h:68:16: fatal error: io.h: No such file or directory #include <io.h>

therefore, I do not have this io.h file. What can I do to compile and use pypcap ?

Before I tried, I tried to do

 C:\pypcap>pip install pypcap Collecting pypcap Using cached pypcap-1.1.4.tar.gz Complete output from command python setup.py egg_info: pcap.h not found ---------------------------------------- Command "python setup.py egg_info" failed with error code 1 in c:\users\USER\appdata\local\temp\pip-build-fvgkhs\pypcap\

and after that I tried to use wheel loading, but it also failed.

Thank you in advance for your help.

Modified Answer

You now have a fully functional MinGW GCC compiler, including header files.

io.h should be in C:\MinGW\include .

UPDATE

I successfully compiled it now using Python 2.7.11 (under Wine, since I do not start Windows, but it should be the same), following the procedure described in your question.

One thing I had to do was change the setup.py parts in pypcap because it did not set the correct paths for pcap include.

Let me know if / when you get there.

Hope this helps.

CHANGES TO setup.py

Replace the _pcap_config function with this modified version:

 def _pcap_config(self, dirs=[ None ]): cfg = {} if not dirs[0]: dirs = [ '/usr', sys.prefix ] + glob.glob('/opt/libpcap*') + \ glob.glob('../libpcap*') + glob.glob('../wpdpack*') for d in dirs: for sd in ('include/pcap', 'include', ''): if os.path.exists(os.path.join(d, sd, 'pcap.h')): cfg.setdefault('include_dirs', []).append(os.path.join(d, sd)) for d in dirs: for sd in ('include/pcap', 'include', ''): for sd in ('lib', 'lib64', ''): for lib in (('pcap', 'libpcap.a'), ('pcap', 'libpcap.so'), ('pcap', 'libpcap.dylib'), ('wpcap', 'wpcap.lib')): if os.path.exists(os.path.join(d, sd, lib[1])): cfg['library_dirs'] = [ os.path.join(d, sd) ] cfg['libraries'] = [ lib[0] ] if lib[0] == 'wpcap': cfg['libraries'].append('iphlpapi') cfg['extra_compile_args'] = \ [ '-DWIN32', '-DWPCAP' ] print 'found', cfg self._write_config_h(cfg) return cfg raise Exception("couldn't find pcap build or installation directory")

Basically this just adds ALL paths containing pcap.h for inclusions.

LINKING

With MinGW (32-bit), you will need a 32-bit Python installation. With 64-bit Python, you need to install MinGW (64-bit) .

So you can install 32-bit Python or install 64-bit MinGW.

We are close now, you will do it :-)
