Dear all,
At work, I'm developing a webapplication with happstack. When I let it
run for some time ( 5min.) it crashes with the following message:
failed to create OS thread: Resource temporarily unavailable
This happens because the server continuously creates OS threads but
never terminates

Thanks Gregory,
Indeed xcode was not installed - however I wonder, why is it a dependency?
It seems quite a heavyweight thing to require for installing Haskell,
and this requirement may very well be a good reason to
Hi,
Is it possible to configure a proxy server for cabal? When yes, how I configure
it?
Thanks.

Currently I'm trying to lern Haskell by doing. After doing some examples I plan

Hi everyone,
Some of the dependencies for Yesod (such as haskell-src) require
happy. For the Yesod in Five Minutes page[1], I've given
instructions to cabal install happy and then cabal install yesod.
However, as Xavier Shay pointed out to me, this won't actually work on
a vanilla install, since
Hi, cafe,
I know this has been treated many times, but I've tried install GTK so
hard without any success that I decided to ask for help.
Firstly, I followed the instructions listed in HaskellWiki [1]. No results.
Then, I followed the instruction from the Mark Shroyer blog [2]. No results.

Hi Daniel,
Gtk2hs site is down by move server, sadly.
The document on http://www.haskell.org/haskellwiki/Gtk2Hs is wrong.

Maybe it's erroring out because you have C:\gtk\bin and C:\Documents

of the STRef at the end, then of course it will not return gradually

In my experience cross platform tools do not work in the presence of spaces
in paths. Because of this when on Windows I have the habit of putting any
cross platform libraries or tools in a non-spaced path. Another option
could be to use the short path names when setting the PATH. GHC and cabal

Hi Klaus,
from your code I cannot tell where exactly you're stuck. A general hint
may be to have a look at the parsec library.

When using c2hs, you can use the inline header commands to define global
variables:

#endc
