[darcs-devel] [issue1846] Darcs does not build in out-of-the-box Haskell Platform on Windows

I'm trying to get it working with my Cygwin install, but no bananas:

*$ cabal install curl
Resolving dependencies...
Configuring curl-1.3.5...
cygwin warning:
  MS-DOS style path detected:
C:\Users\Bob\AppData\Roaming\cabal/share/config.site
  Preferred POSIX equivalent is:
/cygdrive/c/Users/Bob/AppData/Roaming/cabal/share/config.site
  CYGWIN environment variable option "nodosfilewarning" turns off this
warning.
  Consult the user's guide for more details about POSIX paths:

checking for gcc option to accept ANSI C... none needed
checking how to run the C preprocessor... gcc -E
configure: creating ./config.status
config.status: creating curl.buildinfo
cabal.exe: Missing dependency on a foreign library:
* Missing C library: curl
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.exe: Error: some packages failed to install:
curl-1.3.5 failed during the configure step. The exception was:
ExitFailure 1
*
I have libcurl 3 and every other package having to do with curl that is
provided by the cygwin setup.exe. Not sure why it can't find it from within
my cygwin bash shell. I don't think it has to do with the POSIX path
warning, all kinds of other things have compiled curl support (like some
Ruby gems for my Rails work).

I will go ahead and use the binary distribution (if I must choose, it's more
important at the moment that I get up and running with darcs than that I
compile it from the source), will be happy to test 2.4.4 for you.

As far as building on Windows: I happen to have cygwin for completely
unrelated development reasons, but in general I don't like having to compile
with the cygwin DLL requirement, so getting it working on MSYS with MinGW
(or even on Cygwin using MinGW) would be the more ideal approach.

I will definitely check out the wiki's advice along these when I have more
free time to play with building it.

Parenthetically I'll add: I so love my Ubuntu development machine! ;)
