David, could you see to it that something happens on this front?

Re: Call for features for GHC 8.4

[Evan Laforge]

I'd like to see this fixed: https://ghc.haskell.org/trac/ghc/ticket/13604

It's a show stopper that prevented me from being able to use 8.2 at all.

Once again, if no one has time to address it, I'd be happy to take a
look myself.

Call for features for GHC 8.4

[Ben Gamari]

Hello everyone,

The release of GHC 8.4 is quickly approaching, with a release targetted
for February 2018. To allow plenty of time for stabilization, we would
like to cut the ghc-8.4 branch sometime in November. Currently there are
relatively few items on the 8.4 status page [1]. If you have a feature
which you would like to see in 8.4 but is not listed there please do
add it soon.

Also note that if things go according to plan, 8.6 will come a mere six
months after 8.4 so if you have a large feature which won't make it for
8.4, do not fret; another release will be just around the corner.

Cheers,

- Ben

Re: GHC HEAD now needs extra tools to build libffi?

[Moritz Angermann]

Yes, this commit indeed introduced the need for makeinfo, however after some 
debugging and improved packaging of the external libffi library, this 
dependency was removed again, and should not be required with the latest head 
anymore.

Then again this should not result in link issues but rather in build time 
issues.

The key to libffi is the libffi-tarballs git submodule, which contains the 
packaged libffi-tarballs. Make sure all your submodules are also updated.

I usually use `git -x -f -d` (read the documentation first) to ensure a clean 
working tree. Especially as you say you can’t reproduce it on other machines, 
maybe there is a file in your tree that the cleaning did not catch?
