Hi! I'm writing a tool that generates haskell code, build it with cabal and launch it. I want to deliver that tool to clients, but I don't want to force them, to install system wide any specific ghc or cabal version. How can I embed compiled ghc, cabal and selected libraries (for specific platform) in installer of my application?

In most cases, it is sufficient to copy the generated executable; when dynamic libraries are used by the executable (like e.g. wxHaskell does), they must be copied as well, preferably to the same directory as the executable. Note that the dynamic libraries, when created from Haskell source, must be compiled with the same version of GHC as the executable. When e.g. data files are needed and the application uses the function getDataDir from Cabal, an environment variable must be set to indicate where the data files are located. For instance, to install wxAsteroids on an other system, the environment variable wxAsteroids_datadir must be set; see the file wxAsteroids\dist\build\autogen\Paths_wxAsteroids.hs (this file is generated while building the package). An online example is http://darcsden.com/dbp/housetab-export/browse/hsx-0.7.0/dist/build/autogen/...
