No offense :-) Thanks for taking the time to investigate this stuff. It gave
me the opportunity to get a closer look at ghc package management.

I am sorry. I apologize. It was not your fault. It was my fault. 
"unregister --user" drops the global instance when there is no user 
instance, which is when the 2nd time you issued the command. It is a 
ghc-pkg bug.


(I already knew the dual bug: "unregister --global" drops the user 
instance when there is one. I make do with "unregister --global 
--no-user-package-conf".)

Re: [Haskell-cafe] Dynamic loading of module

2011-08-29 Thread Arnaud Bailly

After reinstalling HP 2011.2.0.1 and (re)wiping out user package directory,
things are in better shape and I can now compile the faulty module. I am
well aware I did something wrong at some point in time but I am not really
sure of what happened. I suspect things went wrong when I tried to install a
recent version of snap framework : I vaguely recall having to upgrade some
"core" modules to make cabal happy which obviously was not a good thing.

Maybe this already exists but it would good to have some "session-like"
feature in cabal that would allow fiddling with the configuration and give
the user the ability to rollback what she did. Not sure this would be to
easy to implement though...

Thanks again for your help.

Best regards,
Arnaud

 Hello Albert,
 Thanks for taking the time to help me fix this package stuff. So I wiped
 out my package.conf.d/ and tried to reinstall my stuff. Installing
 template-haskell 2.5.0.0 is ok (2.6 is not, fails to compile on ghc
 7.0.3) but then:

 D:\projets\>ghc --make -package ghc main
 : cannot satisfy -package ghc
 (use -v for more information)

 I suspect I really *do* have to reinstall haskell-platform. Here is the
 output of ghc-pkg list -v:

Different package.conf.d

I suggested obliterating C:\Documents and Settings\abailly\Application 
Data\ghc\i386-mingw32-7.0.3\package.conf.d (on linux it would be called 
~/.ghc/i386-linux-7.0.3/package.conf.d). That would just drop user 
packages and not touch boot packages (global packages for that matter).


You can also see that under the listing of D:/Program Files/Haskell 
Platform/2011.2.0.1\lib\package.conf.d the majority of packages are 
still there, not obliterated. (For example base, bin-package-db are 
still there.)

That'd be expected; you shouldn't simply obliterate package.conf.d, you need
to keep ghc's boot libraries (which include itself as a library).  If the
boot libraries are somehow hosed, you need to reinstall the compiler to get
them back.

Although, I think you were headed there anyway:  template-haskell is a boot
library, since it's very tightly bound to the exact compiler version, so
it's almost always wrong to install it in any way other than as part of
installing GHC itself.

For a 100%-accurate answer, one would need the full history of what you 
did to your computer, which no one knows.


For a 99%-accurate answer, the outputs of "ghc -v" and "ghc-pkg list -v" 
are very good post-mortem information.


A 90%-accurate answer: Given the incomplete information (that's right, 
"ghc-pkg check" is incomplete), there is 90% probability that you lost 
template-haskell, and you must reinstall haskell platform. (No, building 
a new instance of template-haskell is not enough. Generally, replacing 
or overriding libs that come with GHC does not work. See my 
http://www.vex.net/~trebla/haskell/sicp.xhtml )

[Haskell-cafe] Dynamic loading of module

2011-08-26 Thread Arnaud Bailly

Hello,
I stumbled upon this blog post describing a method from dynamically loading
modules using GHC api.

While trying to test the given method, I got the following error which
obviously tells me my packages are not correctly installed but I have no
idea how to fix this.

D:\projets\>ghc -package ghc main.hs --make
: cannot satisfy -package ghc:
ghc-7.0.3-fc75cf67c86ba2c0d64b07024a18d3b4 is unusable due to missing or
recursive dependencies:
  template-haskell-2.5.0.0-7d9b1443ac5ab69e5ed705a487990deb
(use -v for more information)

When I run ghc-pkg check, I got which obviously is bad.
