#124: Windows installer messes up directory structure
-------------------------------+--------------------------------------------
Reporter: Toxaris | Owner: refold

Component: Windows installer | Keywords:
-------------------------------+--------------------------------------------
The Windows installer for the Platform 2010.1.0.0 messes up the directory
structure so that *.h files installed with the extralibs are not found
when installing packages with cabal-install.
The files are searched in {{{$platform\extralibs}}}, but they are
installed in {{{$platform\lib\extralibs}}}.
=== Error Message ===
{{{
> cabal install digest
Resolving dependencies...
Configuring digest-0.0.0.8...
cabal: Missing dependency on a foreign library:
* Missing header file: zlib.h
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the
flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
cabal: Error: some packages failed to install:
digest-0.0.0.8 failed during the configure step. The exception was:
ExitFailure 1
}}}
=== More Information ===
Note that on Windows, digest depends on zlib, which contains a source
distribution of zlib. So the missing zlib.h has been installed with the
Haskell Platform.
{{{

}}}
However, cabal install passes {{{...\2010.1.0.0\extralibs\...}}} to gcc.

As a quick hack, I copied the extra libs to the position where cabal
install wants them, which allows me to install digest (and, in turn,
pandoc).
