问题
I'm trying to install pypcap from: https://github.com/dugsong/pypcap/blob/master/INSTALL#L75
I'm trying to install it on Windows 10 - 64 bit and python 2.7.11 64 bit. I downloaded the source and moved it to c:\pypcap. downloaded pyrex and installed it as well. It put the wpdpack files in c:\wpdpack like the install page says. Created the config file and changed the makefile.
I also installed the mingw from their website with the basic package and the g++ package.
I try 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>
so I don't got this io.h file. What can I do to make it compile and use the pypcap?
Before trying that 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 using the wheel download but it failed as well.
Thanks in advance for your help
回答1:
Unzip the WinPcap Developer pack so that you have
C:\WpdPack\IncludeandC:\WpdPack\LibUnzip the pypcap source so that you have
C:\pypcap-1.1.4\setup.pyInstall the Microsoft Visual C++ Compiler for Python 2.7
Start the relevant cmd prompt for your Python27 bitness from:
Start -> Programs -> Microsoft Visual C++ Compiler Package for Python 2.7Install/build pypcap from that cmd prompt with:
set INCLUDE=%INCLUDE%;c:\WpdPack\Include
set LIB=%LIB%;c:\WpdPack\Lib
pushd C:\pypcap-1.1.4
python setup.py install

Changed answer
Download https://sourceforge.net/projects/mingw/files/Installer/mingw-get-setup.exe/download.
Run it.
Select:
mingw32-base
mingw32-gcc-g++
Select menu Installtion => Apply Changes
Now you have a fully functional MinGW GCC compiler including header files.
io.h should reside in C:\MinGW\include.
UPDATE
I have successfully compiled it now using Python 2.7.11 (under Wine, since I don't run Windows, but it should be the same) by following the procedure you described in your question.
One thing I had to do was to modify parts of setup.py in pypcap, because it didn't set the proper paths to the pcap includes.
Let me know if/when you get there.
Hope it helps.
CHANGES TO setup.py
Replace the function _pcap_config 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")
It basically just adds ALL paths containing pcap.h to the includes.

LINKING
With MinGW (32-bit) you need a 32-bit Python installation. With a 64-bit Python you need to install MinGW (64-bit).
So you can either install a 32-bit Python or install a 64-bit MinGW.
We are close now, you will make it :-)
