RE: [Haskell-cafe] HP/Cygwin and Curl
Thanks very much Claus and Malcolm. You have clarified the situation nicely: I was beginning to suspect my Cygwin setup and I bet that is where the problem lies. I won't have time to straighten my Cygwin environment this week, but when I do I will come back here and explain what went wrong (I have seen evidence of others stumbling on this giving rise to speculative misinformation). Sorry for the confusion!

RE: [Haskell-cafe] HP/Cygwin and Curl
Thanks very much: I didn't know about this resource. I do appreciate all of the hard work everyone has put in and I want to contribute myself, especially in 2011 (I am fully committed until then). For the moment the best contribution I can make is to report the problems I am having. The above wiki page is (of course) too vague about how Cygwin and MSYS can be used. Cygwin is a much better supported product and a much easier way of getting hold of many Unixy things (like X11). AFAIK MSYS doesn't have a proper installer at the moment. It would be nice to know how Cygwin can be used with HP. If the answer is not at all (for serious work) then can we say this very prominently on HP Windows page. How about linking the HP-Windows page to the Wiki article on Haskell for Windows? A FAQ for HP would also surely be useful. If others agree these would be useful and they haven't been when I will pick them up, but first, are these a good idea? My feeling is that the ramp onto Haskell is far steeper than it needs to be considering the fundamental excellence of the parts.

Re: [Haskell-cafe] HP/Cygwin and Curl
Thanks Stephen--that was related to my original question, about using HP with Cygwin. The answer seems to be No!--you must use MSYS (for real work). The short version: - Cygwin provides commandline tools, compilers and libraries - MSYS provides commandline tools for the MinGW compilers and libraries You can use the commandline tools from either Cygwin or MSYS, but you need to compile and link with the compilers and libraries from MinGW. Cygwin's gcc produces binaries that live in a unix-emulation on top of windows, and depend on a cygwin dll to act as a translator. MinGW's gcc produces native windows binaries.

Thanks Claus,
Your condensed summary was my understanding, but if I try to issue
Cabal install --reinstall cmu
It works every time from a MSYS shell, but with Cygwin I get

('cmu' is just an example; the same behaviour seems apparent whatever the

The general answer I seem to have been getting (and responses I have seen
elsewhere top this problem) is 'don't expect the Haskell tools to work with
Cygwin'.
At any rate it seems that, for some people at least, the latest version of
the Haskell tools won't work when launched from Cygwin Bash.

If MSYS works for you, why not stick with it?-)
Cygwin with MinGW tools should work, but it is very easy to mess up
with this setup (configure scripts might not notice that they are on
windows and use the wrong calling convention, Cygwin libraries and
compiler tools might be called accidentally if they are installed, and
so on). Of course, the more people give up and switch to MSYS, the
smaller the chances that such bugs (things that accidentally work when
using MSYS, or with a certain directory layout) get reported and fixed.

You could try running 'ghc -v hello.hs' and check the windres command
for oddities. I have no problems building a simple hello world from Cygwin:
$ uname -a
CYGWIN_NT-6.1-WOW64 VAIO 1.7.5(0.225/5/3) 2010-04-12 19:07 i686 Cygwin
$ type ghc
ghc is hashed (/cygdrive/c/haskell/ghc/ghc-6.12.2.20100522/bin/ghc)
$ ghc tst.hs
$ ./main.exe
Hello, World!
The general answer I seem to have been getting (and responses I have seen
elsewhere top this problem) is 'don't expect the Haskell tools to work
with
Cygwin'.
That tends to be a self-fulfilling prophesy, similar to 'don't expect the
Haskell
tools to work on Windows (because so many people rely on unixisms)'. But
the result is that problems do surface more often in this configuration. If
you
want to investigate, you could file a report on the HP trac.

[Haskell-cafe] HP/Cygwin and Curl
Hi, I am trying to install the curl 1.3.5 hackage on the latest Haskell Platform (2010.1.0.0) on Windows 7. I have installed lib-curl-devel (7.19.6-1) on CygWin but I can't use Cygwin as (apparently) every attempt to install a package ends like this: C:\Program Files\Haskell Platform\2010.1.0.0\lib\..\mingw\bin\windres: can't open temporary file `\/cca01252.irc': No such file or directory Using cabal-install with MSYS generally works. Can HP be used with Cygwin? I have yet to find a way of installing Curl so that the curl hackage will recognise it-does anybody know how to do this? (I couldn't find any explanation of how HP can be used with Cygwin or how to install Curl for use with the hackage. If anyone knows where I can get these that would be fine much appreciated; the Haskell.org outage is compounding this.) Thanks in advance!

Re: [Haskell-cafe] HP/Cygwin and Curl
Hi Chris HP can be used fine with Cygwin. Where a library in the HP is a binding to a C library, the HP supplies the relevant C library as an *.a file, e.g libglu32.a and libglut32.a for OpenGL. Pure Haskell libraries will install fine under Cygwin as well. Bindings to additional C libraries like Curl are problematic, for one thing Cygwin static libraries have a different object format to MinGW ones. With effort and knowledge, FFI libraries/bindings can be made to work with Cygwin but I don't think anyone is looking at this systematically (and documenting their methods). Practically speaking using MinGW / MSYS to build and install bindings is the solution.
