Dear folks,
Thanks for listening to my talk, I appreciate everyone join the discussion and provide feedback, all the opinions are very valuable. For folks who are not present at WineConf, I've attached my slide to http://wiki.winehq.org/WineConf2015?action=AttachFile&do=get&target=... , I'll also create a wiki page on Wine for the Full Stack on Wine idea later.
For people who want to test Cygwin/MSYS2 on Wine earlier, here is the step: 1. fetch latest Wine Staging source code 2. apply a wine hack from https://bugs.wine-staging.com/show_bug.cgi?id=561#c3 3. apply another wine hack from https://bugs.wine-staging.com/show_bug.cgi?id=404#c7 4. compile Wine Staging
Then it will be enough to have Cygwin/MSYS2 works like the slide said (gcc compiles, 300+ MSYS2 packages compiles, Qt compiles, etc). Enjoy!
See also https://github.com/fracting/wine-fracting/wiki/MSYS2-on-Wine#build-status for some other information.
All these will be collect to Wine wiki, I need some more time to do that.
Thank you!
