It's a user-provided build. I guess user has 32-bit userland on 64-bit ARM. ghc-8.2.1 will have cross-compilation and cross-building support. Would you like to try a cross-built binary from ::haskell overlay for ghc-8.2.1_rc3? I'm building the binary package right now against unstable ~arm64 crossdev. I think it will require llvm-3.9 or higher on the target. Can you also post your `emerge --info`? Mostly for my curiosity on how those systems look like. > Note: I don't see arm64 here https://ghc.haskell.org/trac/ghc/wiki/Platforms It's a bit outdated and depends a lot how you squint at the support (use llvm codegen or not, etc.). unregisterised more should work on any arch.

Built aarch64 binary in ::haskell as: https://github.com/gentoo-haskell/gentoo-haskell/commit/444c46bd909a5647d9824559293144723024f191 The easy ways to test if it works at all it to install the binary: $ USE=binary emerge -1 =dev-lang/ghc-8.2.1_rc3 It won't try to compile anything, should only install ghc binary. This cross-compiled binary lacks ghci support thus the easiest way to check if it works is to build a hello world (or 'app-admin/haskell-updater'). More serious test is to build native ghc itself: $ emerge -1 =dev-lang/ghc-8.2.1_rc3 Both GHCs require llvm-3.9 or llvm-4.0 present.
