%description %{wxhpackage}
wxHaskell is a portable GUI library for Haskell that uses wxWidgets.
wxWidgets is a comprehensive C++ library that is portable across all major 
GUI platforms; including GTK, Windows, X11, and MacOS X. Furthermore, it is 
a mature library (in development since 1992) that supports a wide range of 
widgets with native look-and-feel.

wxHaskell exposes almost all relevant wxWidgets functionality -- about 500
classes with 2800 methods and 1200 constants. Furthermore, it adds many
functional abstractions which lead to short and consise code.

This package contains the libraries compiled 
- for : %{hcomp}-%{hcversion}
- with: wx%{wxToolkit}-%{wxversion}

We would like to thank the people of the ELJ Eiffel project, and in 
particular Uwe Sanders, for providing the basic C interface to wxWidgets.

%prep
%setup -q

%build
# - set the "shared-prefix" to null, such that wxHaskell apps are 
#   independent of the location of libwxc.
# - explicitly force a specific haskell compiler
./configure %{configflags} --shared-prefix="" --hc=%{hcomp}-%{hcversion} --hcpkg=%{hcpkg}-%{hcversion} --libdir=%{wxhlibdir}
make

%install
# - we use "install-files" so that the packages are not registered with ghc.
# - we move "libwxc" to "_libdir" so that it can be found by the loader.
