[PATCH] RE: Zenmap Build Guide

["Rob Nicholls" <robert () robnicholls co uk>]

Hi David,

Thanks for that! I had assumed that the error message was down to what I'd
installed, which it was in a way, but it seems it was down to the source
code. Although the page you provided says it's a fix for Python 2.7, it
seems to fix the problem with my Python 2.6.6 based installation.

I've attached a patch that tweaks the line to say
subprocess._subprocess.STARTF_USESHOWWINDOW in zenmapCore\NmapCommand.py.

However, this does break older (e.g. your 2.6.1) Python installations, as it
results in the error "'module' object has no attribute '_subprocess'". This
happens on Python 2.6.5 or lower. Should we include the attached patch and
upgrade to 2.6.6 or should we stick with the current code (and I'll
downgrade to 2.6.5)? I can update the build guide at some point to match
whatever's decided (either way, I'm pretty sure that GTK+ 2.14 is too old to
support gio).

I also noticed that http://www.py2exe.org/index.cgi/Tutorial#Step52 says we
should be distributing the Visual C++ 2008 Redistributable (and not the SP1
version we used to install, and not the 2010 version that's currently in
SVN) when using Python 2.6 or above with py2exe. I'd already updated the
Nmap installer and Visual C++ 2008 SP1 redistributable to use the new 2010
version, but should I look into adding the Visual C++ 2008 RTM (with the ATL
fix) redistributable to the Nmap installer to support Zenmap?

I'm not entirely sure why no one has complained about Zenmap not working
(I'll try the installer on a clean installation of Windows 7 at some point
to see what happens). Perhaps the VC++ 2008 SP1 redistributable allowed
Zenmap to run okay (even though py2exe claim SP1 is the wrong version), or
people have already installed it (either with older versions of Nmap or for
other applications). It will make the Nmap installer a bit bigger though :(

I haven't tried starting a new build environment from scratch for a while,
but there's nothing in the build instructions that looks inaccurate to me.
Here are the versions I have installed:

Windows XP SP3
gtk+-bundle_2.18.7-20100213_win32
Python 2.6.1
Cairo 1.8.8
pygtk-2.16.0-py2.6
pygobject-2.20.0-py2.6
pycairo-1.8.6-py2.6
py2exe-0.6.9-py2.6

GTK+ is installed in C:\GTK and Python is in C:\Python26.

There's a note here about possibly requiring
subprocess._subprocess.STARTF_USESHOWWINDOW instead of
subprocess.STARF_USESHOWWINDOW.

http://stackoverflow.com/questions/1016384/cross-platform-subprocess-with-hi
dden-window/3443174#3443174

Crashing immediately upon launching is what was happening to me before I
added gio.

Are you able to run Zenmap without using py2exe? Like this:

        cd nmap\zenmap
        C:\Python26\python.exe zenmap
