I guess my question is then: why do you want to use Windows in the first place? ha ha :) the same question was asked when i started the nt domains reverse-engineering for samba, in 1996. the answer is: i don't. but there are a lot of users and developers who feel that they don't have a choice. or haven't been given one. so if it's possible for me, as one of the under 1% of computer users i.e. linux to compile stuff that will work on the over 95% of computers used by everyone else i.e. windows _and_ i get to stick to free software principles, that's gotta be good. take pywebkit-gtk as an example. the first-level (and some of the second-level) dependencies for pywebkit-gtk are roughly as follows: * libstdc++ * cairo, pango, gdk, fontconfig, gtk * libxml2 (which is dodgy) * libxslt1 (which is so dodgy and dependent on incompatible versions of libxml2 it can't be compiled on win32) * libicu38 * libcurl * libssl * webkit * python2.5 * python-gobect * python-gtk that's a *big* ing list that comes in at a whopping 40mb of _binaries_. webkit itself comes in at 10mb alone. libicu38 fails _miserably_ to cross-compile with mingw32. i was damn lucky to have beaten it into submission: it took two days and i couldn't run any of the tests, but actually managed to get at least some .libs, .dlls and .a's out of the mess. libxslt1 and libxml2 have compile errors in mutually incompatible versions on win32, plus, unfortunately, the versions that _do_ compile correctly (really old versions like libxslt-1.12 + libxml2-18 or something) are not the ones that can be used on webkit! i had to get the source code for gcc (4.4) because when linking webkit against the MSVC-compiled libicu38 gcc actually segfaulted (!). and that was tracked down to exception handling across process / thread boundaries in libstdc++-6 which had only literally been fixed/patched a few days before i started the monster-compile-process. i tried hunting down python-gobject and python-gtk for win32, but there is a dependency needed before you get to that: python25.lib. as i mentioned previously i tried hunting down a .lib for python25 but of course that would be useless unless i also have a libtool-compiled .a so there wasn't any point. so, all the hard work that i did cross-compiling up webkit for win32 was completely wasted because python itself could not be compiled on linux for a win32 platform. hence my interest in making sure that it can be. _then_ i can go back and revisit the monster compile process and finally come up with the goods, on win32, on the gobject-based DOM-model manipulation stuff i've added to pywebkit-gtk. i've got linux covered, i've got macosx covered. win32 is the last one. l. -- http://mail.python.org/mailman/listinfo/python-list

You can already do that: just install windows python under wine. i tried that a few months ago - the builder requires the MS installer, which segfaulted on my installation of wine (i installed it using winetricks) which left me flummoxed because other people report successful use of MSI. i also don't want just the python.exe, i want the libpython25.a, i want the libpython25.lib, so as to be able to build libraries such as pywekbit-gtk for win32 (cross-compiled using winegcc of course) unpacking the python installer .exe (which was, again, created with a proprietary program) i found that all of the contents were name-mangled and so were useless: i wasn't about to work my way through nearly a hundred files, manually, when i can just as well get python compiling under wine once and then stand a good chance of being able to repeat the exercise in the future, also for python 2.6. so, basically, i really don't want to use visual studio, i really don't want to install a proprietary MSI installer, i really don't want a proprietarily-built python25.exe, and i really don't want a proprietarily-packed installation. i'd just ... much rather be completely independent of proprietary software when it comes to building free software. onwards :) -- http://mail.python.org/mailman/listinfo/python-list

Hm, I could definitely install python - I have python in wine ATM. wine python -c 'import sys; print sys.version' - 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit (Intel)] IIRC, I could build numpy on it, which is far from a trivial package from a build POV :) I think it crashes on wine, though - which I why I did not pursued it so far.

Re: [Python-Dev] compiling python2.5 on linux under wine
anyway, i'm floundering around a bit and making a bit of a mess of the
code, looking for where LONG_MAX is messing up.
fixed with this:
PyObject *
PyInt_FromSsize_t(Py_ssize_t ival)
{
if ((long)ival = (long)LONG_MIN (long)ival = (long)LONG_MAX)
{
return PyInt_FromLong((long)ival);
}
return _PyLong_FromSsize_t(ival);
}
raised as http://bugs.python.org/issue4880
next bug: distutils.sysconfig.get_config_var('srcdir') is returning None (!!)

Re: [Python-Dev] compiling python2.5 on linux under wine

ok ... actually, that's correct. oops.
sysconfig.get_config_vars() only returns these, on win32:
{'EXE': '.exe', 'exec_prefix': 'Z:\\mnt\\src\\python2.5-2.5.2',
'LIBDEST': 'Z:\\mnt\\src\\python2.5-2.5.2\\Lib', 'prefix':
'Z:\\mnt\\src\\python2.5-2.5.2', 'SO': '.pyd', 'BINLIBDEST':
'Z:\\mnt\\src\\python2.5-2.5.2\\Lib', 'INCLUDEPY':
'Z:\\mnt\\src\\python2.5-2.5.2\\include'}
... nd, that means disabling setup.py or hacking it significantly
to support a win32 build, e.g. to build pyexpat, detect which modules
are left, etc. by examining the remaining vcproj files in PCbuild.
ok - i'm done for now.
the project's not complete, but can be regarded as successful so far.
i think the best thing is being able to do import _winreg on a
linux system. that absolutely tickles me silly :)
been running a few tests - test_mmap.py is a hoot, esp. the Try
opening a bad file descriptor... that causes a wine segfault.
if anyone wants to play with this further, source is here:
http://github.com/lkcl/pythonwine/tree/python_2.5.2_wine
at some point - if i feel like taking this further, and if people
offer some advice and hints on where to go (with e.g. setup.py) i'll
continue.
then once that's done i'll do python 2.6 as well.
