ghc is a haskell compiler that cannot be build without a ghc binary. As of 2021-12-08 there is no binary for arm64 in neither the gentoo nor the haskell repo. If you have an amd64 you can cross compile ghc. You can try a binary from somewhere else.


 * pandoc needs ghc

Installing didn't work
make[1]: *** [ghc.mk:992: install_packages] Error 127 make: *** Error 2
 * wget https://downloads.haskell.org/~ghc/8.8.2/ghc-8.8.2-aarch64-deb9-linux.tar.xz
 * ./configure
 * su "make install" leads to
 * utils/ghc-cabal/dist-install/build/tmp/ghc-cabal: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

the unclean way: edit the ebuild

 * edit the ebuild
 * ebuild EBUILD_name manifest
 * then build it once and hopefully native builds will just work, so you can then re-build with uneditted ebuild

 * ebuild ghc-8.10.6.ebuild manifest
