Package and Environment Details

• Package Name/Version: cygwin_installer/2.9.0

Something is changed (recently?) in Cygwin, now the recipe fails to package it:

arch_build=x86_64
build_type=Release
compiler=Visual Studio
compiler.runtime=MD
compiler.version=15
os=Windows
os_build=Windows

Both testing and stable branches are broken now.

@db4 probably, something changed in lake project, I'll take a look

@SSE4 thanks a lot. How do you think is it possible for Cygwin recipe to achieve reproducible builds despite frequent upstream changes? Recipe's version 2.9.0 is misleading - it actually tries to package current Cygwin 3.0.x (which is a moving target). Maybe to use https://github.com/mumble-voip/cygwin-bootstrap or something like that?

It looks like we would need to build it from source in order to do this

[Croydon]

I found http://www.crouchingtigerhiddenfruitbat.org/Cygwin/timemachine.html

But I'm not sure how trustworthy they are. Does Cygwin provide for every version and every package official hashsums we could compare the downloads to?
