conda-build unable to extract tar.xz files on Windows Python2.7/vc9

[dschreij]

I just pushed a recipe to conda-forge and it builds correctly on Windows for Python 3.*, but with Python 2.7/vc9 it reports the following:

Source cache directory is: C:\Miniconda\conda-bld\src_cache
Downloading source to cache: flac-1.3.1.tar.xz
Downloading http://downloads.xiph.org/releases/flac/flac-1.3.1.tar.xz
Success
Extracting download
unxz is required to unarchive .xz source files.

Command exited with code 1

It seems as if unxz is only missing for this version of vc and/or python.

The recipe can be found here: https://github.com/dschreij/staged-recipes/tree/sdl2_mixer/recipes/flac

Sadly, the source is not available in any other archive format, so I'm stuck with tar.xz.

xz can't be compiled with VS 2008. It uses C99, which VS didn't support adequately until VS 2013.

xz as a standalone package would be feasible - built only as an executable that depended on VS 2015 runtime. You can put in a pull request or issue requesting the package change at continuumIO/anaconda-recipes. I must warn you, it may be some time before we can get to it.

This is not a bug with conda-build, though. Closing this issue.

Right then, that sounds like a lot of trouble for a format which is rarely used. I think I am going to find another solution for this problem, maybe create a downloadable zip myself and link to that. Thanks for looking into this!
