Eureeka!
Your info helped...I can't thank you enough...
I can now connect to the database shown in "Real World Haskell" - I was just
about ready to give up...
Now if I can only get GTK and my Mac to work...well we'll start that
tomorrow...enuf to do today...
Thank you
Ps
If anyone want to get a task force started in regard to installing Sqlite3
and GTK, I'll definitely participate...

Kathleen,
Grab this: http://www.sqlite.org/sqlite-dll-win32-x86-3070500.zip
Extract the sqlite3.dll file from inside, copy it to c:\users\user and
to c:\windows\system32
Grab: http://www.sqlite.org/sqlite-autoconf-3070500.tar.gz
Extract the sqlite3.h file from inside, copy it to c:\users\user
Then
> cabal install
> HDBC-sqlite3 --extra-include-dirs=C:\Users\User --extra-lib-dirs=C:\Users\User
should work.
I have only installed it though, I didn't run it.

Subject: [Haskell-beginners] How to use the yaml package?
To: [email protected]
Message-ID: <[email protected]>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Hello,
I want to use YAML in my app
I have run:
cabal install yaml
I have added it to my build-depends line in my .cabal file:
Build-Depends: base,time,yaml
$ runhaskell Setup.lhs configure
Configuring xtdo-0.1...
Setup.lhs: At least the following dependencies are missing:
yaml -any
Oh no! I tried just importing Text.Libyaml in both my app and GHCi but
neither error gave any clues. I also found references to HsSyck,
data-object-yaml and YAML::Tiny libraries, but not sure what I should be
using.
Right now I'm feeling totally lost, not being able to find examples of
code using yaml, nor documentation for how I would use the libraries to
play around with it. Also not comfortable I understand the interaction
between cabal, runhaskell, ghc, and my build file.
Any pointers?
References to documentation I should have read also appreciated.
Cheers,
Xavier
(I don't know how relevant it is, but here is my minimal project I am
trying to add it to: https://github.com/xaviershay/xtdo-hs)

Hi Xavier,
I'm the author of both yaml and data-object-yaml. I recommend you
stick with data-object-yaml: yaml is much more low level. I recently
wrote a blog post about data-object-yaml which you will probably find
useful: http://docs.yesodweb.com/blog/data-object-yaml/ .
As for your installation problem: cabal installs libraries by default
in the user folder, whereas Setup.hs checks the global folder by
default. I recommend just using "cabal configure" and skipping the
Setup.hs file.
Good luck!
Michael

Subject: [Haskell-beginners] Can't find or open a Sqlite3 database in
Windows Vista

...seems like I 'kicked over another bee hive'...plenty of messages in regard
to this when you do google search--->[sqlite3.operational error unable to open
database file in windows vista]
...i'm getting the following error messages when I try to create a database in
Sqlite3:
*Sandbox> dbh <- connect "poddbtest.db"
*** Exception: SqlError {seState = "", seNativeError = 21, seErrorMsg =
"prepare 6: BEGIN: unable to open database file"}
*Sandbox> dbh <- connect "test1.db"
*** Exception: SqlError {seState = "", seNativeError = 1, seErrorMsg = "step:
SQL logic error or missing database"}
Both come from Chapters 21 and 22 in "Real World Haskell"
I can't invoke Sqlite3 from the command line using---> Sqlite3 myDatabase.db...
I created blank files in folder C:\Program Files (x86)\Haskell
Platform\2010.2.0.0\winghci -- seemed to get me a bit further along...at least
I was able to connect...
Is it possible to specify the folder that the database should be created in?
Is it possible to run Sqlite3 from the command line - when it has been
installed using the Haskell wiki?
Has anyone had better success with MySql - I've used it in the past and it was
very reliable?
Thank you
