<div><br></div></div><div>Either/or? As an instructor, I'd recommend you pick one and go with it -- if you need wx, that means Canopy for now.

I've noticed that the anaconda system that C.A. installs uses MinGW on windows to build extensions. </blockquote><div><br></div></div><div>I think Canopy does that too -- at least it did a few years ago. but I _think_ you can build extensions with either MinGW or MSVC for the same binary python -- if it's set up right ;-)</div>
</div></div></div></blockquote><div><br></div><div>We don't use mingw to build packages distributed within canopy (at least not anymore). We build everything with MSVC 2008, as mixing mingw/MSVC often causes trouble.</div>
<div><br></div><div>We do provide mingw so that people can build extensions without depending on MS toolchain, but that's not a setup I would recommend in general. It works well for extensions that don't depend much on the C runtime (numpy is a good example), but as soon as you manipulate IO, etc... you encounter issues linked to ABI incompatibilities between what you get from the python runtime and mingw.</div>

<div><br></div><div>That being said, it is supposed to be a goal for Anaconda to be binary compatible with the <a href="http://python.org" target="_blank">python.org</a> binaries -- so you may well be able to build the way you are, and give the users a way to install it into Anaconda. In theory, binary wheels are the way to do this.</div>

</blockquote><div><br></div></div><div>no -- except by hand with custom code.</div><div> </div><div><br></div><div>I'm still a little unclear on your goals here. If you want to simple be able to tell your students to use Anaconda then look into conda and the CA help lists -- and conda is more or less designed to solve these sorts of problems. also, the odds are good that Anaconda already has boost, and if not someone has done a conda recipe for it:</div>

<div><br></div><div>Note: distutils does not address the third-party non-python dependency problem -- conda tries does address it (though still not clear to me if it helps you build them...) You may also want to look at Gattai, which aims to help you build them:</div>
