[cctbxbb] WSL2 (was: Windows icc builds)

[Kay Diederichs]

Hi Graeme,

I have no solution for this problem but I want to bring up the fact that WSL2 is 
very easy to install on current Windows10, and lets one run the Linux binaries 
(including graphics if you install MobaXterm which has an Xserver) quite 
efficiently.

I have not run into a single problem when trying WSL2 with XDS and XDSGUI; my 
writeup is at 
https://strucbio.biologie.uni-konstanz.de/xdswiki/index.php/Installation#WSL2 .

I think those who struggle with developing for Windows, including you, the 
Phenix team and the CCP4 team, might be able to save a lot of time/effort (and 
those who just use Windows would benefit in the long run by getting used to a 
Linux environment).

Microsoft announced WSLg (the g stands for graphics) which provides an Xserver, 
but this currently requires Windows-Build 21362+ (Windows Insider Program).

Give it a try!

Just my 2 cents,
Kay
