Description Alexis Ballier gentoo-dev 2017-07-10 12:10:43 UTC
Trying to build ghc on arm64, I get:

 * Package:    dev-lang/ghc-8.0.2
 * Repository: gentoo
 * Maintainer:
 * USE:        arm64 elibc_glibc gmp kernel_linux profile userland_GNU
 * FEATURES:   distcc preserve-libs sandbox userpriv usersandbox
 * Checking for at least 8 GiB disk space at "/var/tmp/portage/dev-lang/ghc-8.0.2/temp" ...
 [ !! ]
 * There is NOT at least 8 GiB disk space at "/var/tmp/portage/dev-lang/ghc-8.0.2/temp"
 * Checking for at least 2 GiB disk space at "//usr" ...
 [ ok ]
 * Space constraints set in the ebuild were not met!
 * The build will most probably fail, you should enhance the space
 * as per failed tests.

Oh, that's a shame. 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

It's a bit outdated and depends a lot how you squint at the support (use llvm codegen or not, etc.).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.

Comment 4 Sergei Trofimovich (RETIRED) gentoo-dev 2017-07-11 15:46:10 UTC
Built aarch64 binary in ::haskell as:

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.
