https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: games-util/xivlauncher-1.0.4 fails to compile. Discovered on: amd64 (internal ref: guru_ci)
Created attachment 864633 [details] build.log build log and emerge --info
Got the same result myself, whether or not I enabled the abi_x86_32 USE flag
Fixed on -r1, missing some nugets (version 6.0.12 from runtime and aspnetcore) that for some reason are not required on my machine.
This is impossible to solve in current state of dotnet in ::gentoo + ::guru. This issue is solved in ::gentoo-dotnet-2023 (with questionable ways). The issue is that dotnet-sdk pulls in *some* nugets with specific version always during pkg builds. Hack is to pull in them proactively with dotnet-sdk installation.
