gitian linking problem for Windows cross-compile #7492

Attempting to build the Windows gitian build for any of the following tags fails on my system:

v0.12.0rc{1,2}

Strange - no one else reported this. I wonder what is different about your setup.

Can you try wiping the cache and building again? (preferably rc5) There were issues with a toolchain change in Ubuntu at approximately the same time that this happened, see also https://github.com/bitcoin/gitian.sigs/pull/305

Success in 6d307c73881220f49728ede094f4ee65f0600849 PR: https://github.com/bitcoin/gitian.sigs/pull/313 Cleared my cache and added that to my build script logic; I believe cfields said something about fixing the problem so it's no longer a problem in IRC.

In any event, all's well with rc5. Thanks!

Awesome, closing this issue then
