Dear devs
I wanted to install GHC 8.10 on my WSL2 (Windows Subsystem for Linux) computer.
So I went here
https://www.haskell.org/ghcup/
and followed the instructions (the curl … command). There was a long pause then
[ Info ] verifying digest of: ghc-8.10.4-x86_64-deb9-linux.tar.xz
[ Info ] Unpacking: ghc-8.10.4-x86_64-deb9-linux.tar.xz to /tmp/ghcup-khiegA
[ Info ] Installing GHC (this may take a while)
[ Error ] BuildFailed failed in dir "/tmp/ghcup-khiegA": NonZeroExit 2 "make"
["install"]
Check the logs at "/home/simonpj/.ghcup/logs" and the build directory
"/tmp/ghcup-khiegA" for more clues.
Make sure to clean up "/tmp/ghcup-khiegA" afterwards.
"_eghcup --cache install ghc recommended" failed!
I looked in the logs as suggested, and found this in the tail of ghc-make.log

So I seem to be stuck. Any ideas? I feel embarrassed not to be able to
install GHC 😊.
