Actually, your alex is /too/ new. See
https://gitlab.haskell.org/ghc/ghc/-/merge_requests/4657. If you take
the latest master, it will contain that, and your problem will be fixed.

Without having particular knowledge about this specific error: try
upgrading `alex`, the tool that GHC uses to produce its lexer. It's
possible a newer version of that tool will fix this problem.

I am having some trouble building ghc on ubuntu. I have ghc 8.8.4
installed on the machine. I pulled from the main repository and
followed the instructions here:
https://gitlab.haskell.org/ghc/ghc/-/wikis/building/hadrian
<https://gitlab.haskell.org/ghc/ghc/-/wikis/building/hadrian>
Building with:
./hadrian/build -j
it builds for a long time until it finally fails with the message
below. I would appreciate some advice on how to fix this.
Thank you,

===========================
Exit code: 1
Stderr and Stdout:
_build/stage1/compiler/build/GHC/Parser/Lexer.hs:3495:3: error:
Variable not in scope: int16ToInt# :: Int# -> Int#

3495 | int16ToInt#

_build/stage1/compiler/build/GHC/Parser/Lexer.hs:3520:3: error:
Variable not in scope: int32ToInt# :: Int# -> Int#
|
3520 | int32ToInt#
| ^^^^^^^^^^^
===========================
On that line (in Lexer.hs) we see:
#if __GLASGOW_HASKELL__ >= 901
int16ToInt#
#endif
(indexInt16OffAddr# arr off)
#endif
so we are in the "then" clause and somehow "int16ToInt#" is nowhere
to be found.
