I have made available a build of GHC 8.2.2 with the config option:
You may find this useful if you are using Ubuntu 16.04 on Windows
Subsystem for Linux.
Although Microsoft has been making gradual progress on the large
address mapping issue, and the situation is much improved, there
is still an extra startup latency of about 13 secs. for applications
that pre-map a large address space as GHC does by default. This makes
the standard GHC binary unusable for compiling projects of any
WSL is now out of beta. It can be enabled on any computer running
Windows 10. Almost all 64-bit linux binaries run fine out of the box
on WSL. GHC is unfortunately an exception, due to its large address
space mapping behavior. WSL is extremely useful as a development
platform, except for this annoyance for Haskell developers.
Could we consider providing binary installers with
--disable-large-address-space as an official part of our releases? It
seems that it would take very little extra work to do so: just run the
build for latest Debian twice, once as usual and once with
--disable-large-address-space. Is there anything I could do to help?
