Imagemagick / MagickWand under alpine linux / python-alpine

The python implemention of MagickWand, aptly named Wand, requires ImageMagick and MagickWand installed. While building docker images using the python:alpine base images, these dependencies can be installed through:

ENV MAGICK_HOME=/usr
RUN apk add --no-cache imagemagick && \
apk add --no-cache imagemagick-dev

The first one is required for Wand to find the installed MagickWand libraries, while the second installs the imagickmagick development dependencies (and thus, the magickwand shared library).

cmd.exe – program has stopped working – but it works in Windows Explorer?

After digging through this issue for _at least_ four hours today, I’ve revisited an issue that crept up 1,5 years ago. This time I found out that it actually happened to most 32-bit programs launched under cmd. Since the Android SDK’s utilities are compiled in 32-bit mode by default, this time I had to actually find out what was causing the issue.

Turns out it was ansicon.exe. After starting the 32-bit cmd.exe from windows\SysWOW64 and stuff worked – I discovered I got an error about ansicon.exe not being able to load. Removing ansicon.exe completely solved the problem. I’m .. stunned.
