Building failed caused by a syntax error in scanner.c

Summary

I tried building helix as per the instructions on the website and got the following error:

  --- stderr

  Caused by:

Reproduction Steps

I'm running Windows 11 and I opened a command prompt with Admin privileges, then navigated to "C:\Program Files\Helix". I then followed the instructions:

git clone https://github.com/helix-editor/helix
cd helix
cargo install --path helix-term

Helix log

No response

Windows 11

Terminal Emulator

Windows cmd

Are you running an old version of a C/C++ compiler? IIRC the haskell grammar only needs C99 now (#1417)

[SpacewaIker]

My compiler version is gcc 6.3.0 on windows cmd. I also tried WSL, and there, it is version gcc 9.3.0. I actually just tried to install helix with a WSL terminal and everything worked. The only issue is that the hx command is only recognized in WSL terminals, not my cmd terminals...

So I tried updating my version of GCC/MinGW on cmd but I can't figure out how to do this. I tried looking for solutions online but they didn't seem to work... However this seems to be the problem, not helix

Although that could mean that the haskell grammar needs a more recent version of C than C99? I'm not sure

[SpacewaIker]

I succeeded in upgrading GCC, I now have gcc version 12.1.0. However, I got the same error at line 211 in scanner.c in the haskell grammar directory. I'm not sure why it worked with WSL but not with cmd though...

I confirm this issue on Cygwin version 3.3.5-1 running on Windows 7. Building fails with exactly the same error output in scanner.c

Helix now requires a C11 compiler for compiling grammars so I am closing this as stale.

running on Windows 7.

Windows 7 is also EOL and not supported by rust (and by extension helix).
