`gcc.exe' failed in phase `C pre-processor' error message in /dist-newstyle/ folder

I have this project on a subject 'Languages and Compilers' Where we write parsers in Haskell. At the moment I'm working on this 2-Arrow project where we use the 'alex' and 'happy' libraries to create a parser.hs and lexer.hs file from a lexer.x and parser.y file. While trying to build my framework (cabal build in the project directory) I get the following error message:

C:\\ ... \2-Arrow\dist-newstyle\build\x86_64-windows\ghc-9.2.4\assignment-arrow-0.1.0.0\x\arrow\build\arrow\arrow-tmp\Lexer.hs:1:1: error:
    `gcc.exe' failed in phase `C pre-processor'. (Exit code: 1)

    `gcc.exe' failed in phase `C pre-processor'. (Exit code: 1)

If they were error messages originating from the code I wrote I would at least have a direction to look for solutions, but these errors come from the /dist-newstyle/ folder. Which, in my understanding, is a folder for intermediate files used in building the program. So I'm kind of at a dead end at the moment, since reinstalling 'happy' and 'alex', and updating cabal to latest version all did not change anything. Does anyone have any advice for resolving this error? Any help is greatly appreciated!!

(project framework from uni: https://www.cs.uu.nl/docs/vakken/b3tc/downloads-2018/2-Arrow.zip (depends on 'happy' and 'alex' packages). At first I thought the problem could lay in the framework, but I checked with the professor, he stated that others had no issues, so I don't think that's the problem)

Solution

  • I went to my seminar and asked the TA for help. After some time he proposed that maybe the folder location was the problem. Lo and behold, after moving the folder from my OneDrive folder (which is also saved locally) to my C:\\ directory, the project finally compiled! I have no idea why this would be the case, so I have posted another question here Folder location makes Haskell project incompileable.
