CI: build pandas on windows (appveyor)

[jreback]

Here is a collection of build scripts/tools for windows:
a nice conda recipe:

I have found many confusing explanations/suggestion on the web on how to build python extensions on windows 32/64 bit. The following is very simple to build from master.

Follow the instructions on the following link to build on windows with a binary compat to the existing python. Bascially.

http://pybytes.com/pywavelets/dev/preparing_windows_build_environment.html#installing-windows-sdk-c-c-compiler

Essentially:

• download the Microsoft SDK (you need the 64-bit one of you are on a 64-bit machine, even if you are going to want to build 32-bit builds); this is just the install kit. I used http://www.slysoft.com/en/virtual-clonedrive.html to mount the .iso and install it
• open the CMD Shell (installed onto the start menu)
• set the env variables (I just copy pasted, but you can make a bat file if you want). for either 32 or 64 bit.

you can then just

c:\python27\python.exe setup.py build_ext --inplace
c:\python27\scripts\nosetests pandas

Note: You should compile extensions with the same compiler used for compiling your python binary.
That's VS2008 for py<=3.2, and VS2010 for py3.3.

Thanks for the link jreback. I've tried the MinGW C/C++ compiler, but haven't been able to build the dev version of pandas on a Windows 7 (64 bit), Python 2.7.6 version. I posted my steps on Stackoverflow here: http://stackoverflow.com/questions/21684814/python-compile-dev-build-on-windows The error I get is "collect2: ld returned 1 exit status error: command 'gcc' failed with exit status 1". Any suggestions?

[jreback]

never tried with that compiler, you can build with MS C++ compiler according to the instructions above. I posted a build script on #6324 (at the very bottom).

You have to have the environment exactly right.

Also I post updated binaries based on master at: http://pandas.pydata.org/pandas-build/dev/

AFAIK mingw only will build the 32-bit version

Thanks, I think that was the issue!

I tried this out - seems to work well.

Any takers to have pandas work?

quick and dirty (works on 3.4): https://github.com/jreback/pandas/tree/appveyor

Related: I think we should seriously consider using miniconda. We could completely get rid of wheels!

[jreback]

yep I think their is an issue about that

go for it!

statsmodels does this already iirc

#6870

[gepcel]

It took me a whole Sunday to make this work.

this finally works and passed on py 2.7/3.4/3.5

& we have a green badge: https://github.com/pydata/pandas
