Is your wx-config working ?
You can try: *wx-config ?help*
If not, try with another, you can use these ones:
- download from https://sites.google.com/site/wxconfig/sourcecode
and compile with g++ wx-config.cpp -o wx-config.exe
- or download directly the .exe from
http://sourceforge.net/projects/wxhaskell/files/wx-config-win/

No, I am not sure of this - I followed the instructions at:
http://www.haskell.org/haskellwiki/WxHaskell/Windows#wxWidgets_2.9_and_wxHaskell_0.90.x
The describe the "install" as the wxWidgets install of source code, and then
how to compile it, and then just to do cabal installs, which is what is failing.
The cabal install error describes some configuration options, but I don't know
where or how they are intended to be used.
This problem can usually be solved by installing the system packages that
provide these libraries (you may need the "-dev" versions). If the
libraries
are already installed but in a non-standard location then you can use the
flags --extra-include-dirs= and --extra-lib-dirs= to specify where they
are.
I see in my cabal directory that it has files :
Wx-0.12.1.6,
Wxcore-0.12.1.7
Wxdirect-0.12.1.4
Wxdirect-0.90.0.1
I also notice that these instructions require a bunch of PATH fiddling that I
never had to do before for wxWidgets /wxHaskell 2.8.
Also that it asks to install a path pointer to the cabal directory to
\wxc-%WXC_VERSION%\%GHC_VERSION% which file does not exist on my system. ??

Right, since the fullscreen mode was introduced, the API is "display
displayMode backgroundColor picture" where displayMode is Window or
Fullscreen (with relevant title, size and position details). So :

What's non-obvious and trip a lot of people when they try to use
regexes in Haskell is that most regex libraries use the same
interface, which is specified in the regex-base and consists of
several typeclasses that offers a very high degree of flexibility.
=~and =~~ are only the simplified front-ends to this and are pretty
inadequate for advanced usages (for instance compile and use multiple
time the same regex, you should really avoid =~ in this case, or
additional regex compilation options). To see the basic interface,
look at Text.Regex.Base.RegexLike :
http://hackage.haskell.org/packages/archive/regex-base/latest/doc/html/Text-Regex-Base-RegexLike.html
.
In particular, what you want to do should be done with makeRegexOpts
and match (or matchM), note that the available compilation and
execution options can vary depending on the regex library you use and
for regex-pcre, they're documented there :
http://hackage.haskell.org/packages/archive/regex-pcre/latest/doc/html/Text-Regex-PCRE-Wrap.html#g:4

First, you should make sure for yourself that wxWidgets 2.9 is well
installed, for that you can try to build the wxwidgets' examples
cd c:\wx\samples\minimal
mingw32-make -f makefile.gcc BUILD=debug
Then, I can think that it is just a problem of configuring and installing
wxhaskell.
For the paths you have to set, probably the wxc is not installed on your pc
yet, and probably that's why you couldn't find. But you should follow the
way setting those paths and put the right versions of the libraries you are
installing.
Best wishes, Carlos Gomez

Thank you for this important detail.
Following the advice in this thread I tried to rewrite the function in
terms of the lower-level interface instead of using =~~
-- qualified import to avoid clashes in main program
import qualified Text.Regex.PCRE as RE
regexReplace' :: String -> (String -> String) -> String -> String
regexReplace' regex replace text = go text
where
regex' :: RE.Regex
regex' = RE.makeRegexOpts RE.defaultCompOpt RE.defaultExecOpt regex
replace' :: RE.MatchText String -> String
replace' = undefined
go text = case RE.matchOnceText regex' text of
Just (before, match, after) ->
before ++ replace' match ++ go after
_ -> text
Did you mean something like this? (besides that the replace' function
still has to be filled in)
If this is correct ... I am still a little lost though. I cannot come
up with a way of matching the actual String out of the MatchText
returned by matchOnceText ...
http://hackage.haskell.org/packages/archive/regex-base/latest/doc/html/Text-Regex-Base-RegexLike.html#v:matchOnceText
If I should structure the entire function differently, I would be very
grateful to receive some pointers how.
Best regards,
rico
