This is not a huge deal, but I believe it is worth mentioning because
there is a group of users who still want to use deal.ii on Windows.
Windows 10’s Anniversary Update (build 1607) brings Linux Bash Shell
based on Ubuntu. It is really easy to install and may replace (in the
future) more sophisticated virtual machines like VirtualBox.
Activate the "Developer Mode" switch in Settings > Update & Security >
For Developers. Open Control Panel, click "Programs" > "Turn Windows
Features On or Off" under Programs and Features. Enable the "Windows
Subsystem for Linux (Beta)". After that you need to reboot and "Bash"
will be available in Start Menu. You can install additional packages
using sudo apt-get install <package> command.... and build deal.ii.
Deal.ii 8.4.2 builds and installs successfully. Quick Tests passed.
Simple examples looks to work correctly.
However, I had a problem to build current git version.
expand_instantiations fails with "Invalid instantiation list: missing
'for'" for source/fe/fe_bdm.inst. So it will require further investigation.
TL;DR. Linux shell in Windows works like small virtual machine (but it
is not a virtual machine) with shared file system. This is still beta
but you can build and run deal.ii based applications. I also see some
drawbacks. Graphical application works... sometimes. Compilation will
produce valid linux binaries so the solution is rather not portable
between different windows systems.
Last but not least. There is a plugin (paid) for Visual Studio which
supports building and debugging using Linux subsystem in Windows.
Best regards,
Krzysztof
