Ben,
I saw that you responded to my question in #ghc on freenode last weekend (mdunnio), and I missed your message.
Michael, I would be happy to help. I'm CCing ghc-devs so others may benefit from this discussion.
I'm trying to build a cross compiler using ghc 8.0.1 to build ghc 8.4.3. You mentioned that you have experience.
Have you tried on newer versions of GHC? I've looked at a few guides (mostly https://gitlab.haskell.org/ghc/ghc/wikis/building/cross-compiling) and they all are using pre-8.0. The problem I'm running into now just seems to be that I can't build the base packages (ghc-pkg specifically).
My configure command is:
./configure --target=arm-linux-gnueabihf CC=arm-linux-gnueabihf-gcc --enable-unregisterised
This is helpful to know but you didn't specify what your `make` invocation looks like or your mk/build.mk. It would be very helpful to know both of these things. Presumably you at least had to set `HADDOCK_DOCS=NO` since otherwise the build system fails very early on. Cheers, - Ben
