Originally I was trying to install turbinado which depends on plugins>=1.4. Actually I don't know how turbinado uses plugins. But still I can't build it because of plugins. I wonder how "turbinado guys" builds hs-plugins with ghc-6.10.1. On Sun, Mar 15, 2009 at 12:04 PM, Don Stewart wrote:

It depends on if you need 'eval' or object loading capability.

For true plugins, hs-plugins is still the only binding to the GHC rts object loader, for eval-like mechanisms, we've a number of bindings to the ghc-api bytecode interpreter, such as hint.

That said, hs-plugins is kinda sorta patches-applied maintained.

I believe that hs-plugins has fallen out of use, on #haskell, I was directed to hint[1]. IIRC, I had to disable some packages because of cross installation.

Hi!

I was trying to install hs-plugins both from sources "$./Setup.lhs ..." and with "$cabal fetch&&cabal install" and both failed. It always reports that Linker.h is missing. I have tried to use --extra-include-dirs with path to ghc-6.10.1 dir and ghc-6.10.1/include dir. Nothing changed.

Here is a report from Setup.lhs:

Setup.lhs:2:2:     Warning: In the use of `defaultUserHooks'              (imported from Distribution.Simple):              Deprecated: "Use simpleUserHooks or autoconfUserHooks, unless you need Cabal-1.2              compatibility in which case you must stick with defaultUserHooks" Warning: defaultUserHooks in Setup script is deprecated.

It's a bug in the package that was exposed when Cabal-1.6.0.2 started checking for header files and C libs. I reported the bug to the package maintainer at the time of the release of Cabal-1.6.0.2.

Until the maintainer updates it, the fix is to edit the .cabal file and simply remove the mention of Linker.h. You can use the new cabal unpack command:

 cabal unpack plugins  cd plugins-1.4.0  vi plugins.cabal  cabal install
