Unable to runhaskell my wxHaskell program that works in GHCI
I am trying to create a HelloWorld.exe on Windows 7 that demonstrates a very simple wxHaskell program I have found online. The code is below:
module HelloWorldWX where
import Graphics.UI.WX
main :: IO ()
main
= start hello
hello :: IO ()
hello = do
f <- frame [text := "Hello!"]
quit <- button f [text := "Quit", on command := close f]
set f [layout := widget quit]
in a file called HelloWorldWX.hs. I downloaded the binary distribution of wxHaskell (wxInstall-Achelanne-64-0.1). After running Install.bat I noticed it used Cabal to set up a new package location where it installed wx-0.92.0.1 and all of its depedencies. The first time it ran it failed for some non-specified reason. I ran ghc-pkg list and found all of the packages were listed in the new cabal package location. I decided to unregister all of the packages and try again. This second time it was successful and prompted me to include the following directories in my search path which I did:
C:\Users...\Downloads\wxInstall-Achelanne-64-0.1\DLLs;C:\Users...\Downloads\wxInstall-Achelanne-64-0.1\wxWidgets\lib\gcc_dll
At this point when I loaded HelloWorldWX.hs into GHCI and ran main, I got the window frame with the Quit button like I expect.
I then compiled the .hs file into a .o file. I then attempted to create an executable with the following command:
ghc -v -o HelloWorldWX HelloWorldWX.o

I am not really sure why it is having problems finding these references.
I tried executing then with
runhaskell HelloWorldWX.hs
and received the following error popup from ghc:
The Verbose flag being set here gives a bunch of information that doesn't really elaborate on any specific problems.
I am running Haskell GHC 7.10.3 full package from Windows Installer to a local Users directory. I do not have Local Administrator privileges on this workstation but I could try on another machine.
Any clues? I imagine the first failed install of wxHaskell has corrupted something or I am running into a privilege issue.
Solution
I figured out what the problem was. I forgot that for GHC to create an executable that you need to explicitly specify Cabal packages that you wish to include. Commenter Tomasz Lewowski was partially correct. The -L option for linking libraries was required by gcc, however the ghc application intelligently adds ALL the required library paths for a given Cabal package by using the -package option.
The second part of making this work was that I needed to compile the .o file specifying -main-is for the main method. I wrote up the simple batch file and got it working.
ghc -v -main-is HelloWorld.main HelloWorld.hs
ghc -v -o HelloWorld HelloWorld.o -package strict-0.3.2 -package wx-0.92.2.0 -package wxc-0.92.2.0 -package wxcore-0.92.2.0 -package wxdirect-0.92.2.0
This created the Windows executable just fine and it works like a charm.
