hs-language-c: "runhaskell" command fails during build

[twilsonco@…]

See attached log. During build, the command "runhaskell" exits with status 1. Also many warnings of missing directories during ghc check even though ghc (7.8.3_2) is installed and active.

Sorry for the lack of information in the ticket.

port is hs-language-c @0.4.2_5 (devel, haskell)

error is "Error: Processing of port hsshellscript failed", and

":info:build Command failed: cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_hs-language-c/hs-language-c/work/language-c-0.4.2" && runhaskell Setup build -v" in the log file.

Thanks,

Tim

The warnings from ghc-check are not causing the failure. The problem likely is that the version of hs-language-c is too old for the current GHC and needs to be updated.

It should be as simple as

• locating the Portfile (port file hs-language-c)
• making a backup copy for later diff (cp Portfile{,.orig})
• modifying the version number at the end of the haskell.setup line and removing the revision line
• running sudo port -v checksum in the directory (which will fail and print the correct checksums)
• updating the checksums in the Portfile
• running a test build (sudo port -vt destroot)
• creating a patch (diff -u Portfile{.orig,}) and attaching it here

Can you do that?

I'm confused. hs-language-c is not a dependency of ghc, so why would changing the version number of hs-language-c help? Shouldn't I instead change hs-language-c's ghc dependency to require the current version of ghc?

Also, to what version would I be changing hs-language-c to? And if I changed the version, wouldn't I also need to provide the updated port so that the newer version can actually be installed?

I'd be happy to help with Macports since I love it and depend on it so heavily, but I need a little more information.

Thanks

Oh, because in the error: ":info:build Command failed: cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_hs-language-c/hs-language-c/work/language-c-0.4.2" && runhaskell Setup build -v"

It's looking for .../language-c-0.4.2, that is the version number I should change to (by simply removing the revision line). Then follow the rest of your instructions. I'll try and if it builds then I'll upload the patch.

Thanks

GHC has been updated to the latest version, but hs-language-c has not. I'm proposing to update hs-language-c to the latest available version. Run port gohome hs-language-c to open its homepage which has a list of versions. If you locally modify your hs-language-c Portfile you can run a test build. If it builds, I can commit this patch to make it available to everybody.

[twilsonco@…]

Ahh. That makes more sense :) You're a wealth of knowledge.

Changed to most recent version (0.4.7), updated checksums, and test built gave no errors. Running sudo port install installed successfully. (Unfortunately, the port hsshellscript, which I was trying to install in the first place, has its own errors that are different from those encountered here. Maybe I can help with that one too!)

Thanks for the help!
