MingW uninstallation / parallel installation question

[Matthias Kauer]

Hi,

I'm wondering what MingW is required for in pythonxy. 

More specifically, for C++ development purposes, I'd like to upgrade MingW to a newer version. Is the best option to

1) install the newest pythonxy? Does it have MingW 0.6 with gcc 4.6?

2) update from within Mingw32-xy (assuming you bring the update software)

3) uninstall pythonxy, reinstall without mingw, install mingw on its own

4) install newer mingw version in parallel - probably a really bad idea, no?

Thanks for weighing in on this.

Best,

Matthias

You can use any official 32 bit Mingw32 build with PythonXY 2.7.6.0 . Earlier (unmodified) Python versions were limited to 4.5.2 due to a long standing bug - http://bugs.python.org/issue12641.

Yes. If you want to use something more modern than 4.5.2 then just skip the XY mingw32 install.

2) update from within Mingw32-xy (assuming you bring the update software)

Yes, mingw-get is included. 

3) uninstall pythonxy, reinstall without mingw, install mingw on its own

You can just uninstall mingw32  

4) install newer mingw version in parallel - probably a really bad idea, no?

No, its fine. Python will pick up the first on the PATH. In fact you can experiment with many Mingw32 versions by changing the PATH.
