cabal errors

Gregory Guthrie-2
I'm having some issues with Cabal ,  wonder if they are known issues.

1) I had a previously working installation of files, hadn't used them for some time, did Haskell upgrades (chocolatey), and tried to recompile.
I got a weird error on running the build -
     Program 'apl.exe' failed to run: The application has failed to start because its side-by-side configuration
     is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detailAt line:1 char:1
     + ./apl
     + ~~~~~.
     At line:1 char:1
     + ./apl
     + ~~~~~
    + CategoryInfo          : ResourceUnavailable: (:) [], ApplicationFailedException
    + FullyQualifiedErrorId : NativeCommandFailed
Chasing this all around - no solutions so I started over, in a new location, adding one file at a time.
Worked fine.
2) So I then has a current working build in some top level xTest temporary directory.
      (Just a direct copy of all the files, and "cabal v2-build")
3) So I then just copied all the source files back to a desired installation place, with a longer path name.
4) But there it fails to build:
     PS D:\CS\Courses\long path\Solns\All Solutions> cabal v2-install
     Wrote tarball sdist to D:\CS\Courses\long path\Solns\All Solutions\dist-newstyle\sdist\apl-0.0.1.tar.gz
     Resolving dependencies...
     Build profile: -w ghc-8.10.1 -O1
     In order, the following will be built (use -v for more details):
      - apl-0.0.1 (exe:apl) (requires build)
     cabal.exe: Failed to unpack apl-0.0.1. The exception was:
     dieVerbatim: user error (cabal.exe: Package .cabal file not found in the tarball:
     C:\Users\guthrie\AppData\Local\Temp\cabal-install.-2584\dist-newstyle\tmp\src-2584\apl-0.0.1\apl.cabal)
5) Just copying (again) the same folder of files which is failing to a top level new folder (yTest), deleting the dist-newstyle folder,
     And running "cabal v2-buld" again, all works fine, no errors, executable built.

Three directories, all with the same files - one fails.
?? The only difference I can see is the long path name with blanks in it - is that an issue?

Re: cabal errors

Hmm, I just did a 4th test, copied the same directory of sources to a top level directory, but also with a blank in the name of the directory, works fine.

So I made a 5th variation, copied he whole thing (working) back to a sibling directory of the original failing one.

It did a build, then fails on execution -
      Program 'apl.exe' failed to run: The application has failed to start because its side-by-side configuration
     is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more
    detailAt line:1 char:1
     + dist-newstyle\build\x86_64-windows\ghc-8.10.1\apl-0.0.1\build\apl\apl ...
     + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~.
     At line:1 char:1
     + dist-newstyle\build\x86_64-windows\ghc-8.10.1\apl-0.0.1\build\apl\apl ...
     + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ResourceUnavailable: (:) [], ApplicationFailedException
    + FullyQualifiedErrorId : NativeCommandFailed

Only difference I can see between working and failing ones is their location; they are on two different partitions(?).

So two directories, same location, both identical to a third at a top level, top works fine these two fail differently. ??
