Can't build network package on Windows after chcp 65001

[igrep]

Describe the bug

Building a package depending on network fails due to the error below after chcp 65001:

realgcc.exe: error: dist\build\Network\Socket\Info_hsc_make.o: No such file or directory

To Reproduce
Steps to reproduce the behavior:

$ mkdir cabal-depending-on-network
$ cd cabal-depending-on-network

# Delete %APPDATA%\cabal\store\network-3.1.1.0-* in advance.
# Then append `, network == 3.1.1.0` to build-depends of cabal-depending-on-network.cabal
#      (I haven't tried the other versions of network)

$ chcp 65001
Active code page: 65001

$ cabal v2-build
Build profile: -w ghc-8.8.1 -O1
In order, the following will be built (use -v for more details):
 - network-3.1.1.0 (lib:network) (requires build)
 - cabal-depending-on-network-0.1.0.0 (exe:cabal-depending-on-network) (dependency rebuilt)
Starting     network-3.1.1.0 (all, legacy fallback)

cabal.exe: Failed to build network-3.1.1.0 (which is required by
exe:cabal-depending-on-network from cabal-depending-on-network-0.1.0.0). See
the build log above for details.

Expected behavior

The cabal-depending-on-network package should be build with network-3.1.1.0.

System information

• Windows 10 ver. 1809
• GHC: 8.8.1
• cabal --version:
  • cabal-install version 3.0.0.0
  • compiled using version 3.0.0.0 of the Cabal library

Additional note

• Default Code Point: 932 (Windows-32J. I use Japanese Windows)
• stack build doesn't cause the same issue.
• My APPDATA and USERPROFILE don't contain locale characters.

I'am not sure if cabal-3.0.0.0 could be used with ghc-8.8.1, see #6327

[hvr]

#6327 is about building cabal-install-3.0 w/ GHC 8.8.1; in fact, lib:Cabal 3.0 (and transitively exe:cabal-install-3.0) is required for proper GHC 8.8.1 support (but you can't build exe:cabal-install-3.0.0 w/ GHC 8.8.1 -- but in case of windows you can simply grab either the cabal 3.0 .exe from http://downloads.haskell.org/cabal or via choco install cabal)

[jneira]

Thanks for clarification i misreaded the issue.
I've tried to reproduce and cabal built succesfully the package in my windows 10 using cabal-3.0.0.0 with cabal get nerwork-3.1.1.0 && cd nerwork-3.1.1.0 && cabal build
@igrep have you tried to build it standalone?

[igrep]

@jneira No. Can that be a workaround? If I remember correctly, when I tried cabal v2-build network in the same directory where I met the same problem for the first time, it was successful but cabal v2-build after it resulted in the same (still had to build network package, then exited with the same error).
So I guess building standalone isn't a workaround.

[Mistuke]

This isn't a cabal issue.

realgcc.exe: error: dist\build\Network\Socket\Info_hsc_make.o: No such file or directory

This is coming from hsc2hs which failed while processing Info.hsc. The current latest version of hsc2hs has a race condition on Windows which makes it non-deterministically work or fail.

The git version is more stable but there's no release for it yet on Hackage.

[phadej]

I recall seeing some discussion about hs2hsc on #ghc channel. I suppose the hs2hsc will be released around GHC-8.10 release time, the latest.

@Mistuke thanks for your insight. I'm closing this, as there's nothing to be done.

[Mistuke]

@igrep as a workaround you can build and install hsc2hs from source from git. That should give you a working version.
