[Haskell-beginners] Just started working with Haskell. Need some help

Hi,


Thanks for the replies.


I was able to solve the problem


Simply by deleting everything completely...........and re-installing the ghc from scratch,  along with all haskell packages


(This is what I did earlier;  but apparently, I missed something)


Anyway, it's working fine now

Hello again.


Thank you all for your very helpful replies  (below)


Here is the error I got when I tried to run my script :


Could not find module `Graphics.GD'
Locations searched:
Graphics/GD.hs
Graphics/GD.lhs




As with the previous errors, I went on Google, to find out which module and/or package I needed to install.


Apparently, I need something called "GD"


When I tried :   cabal install gd


I got the following :




Resolving dependencies...
Configuring gd-3000.7.3...
cabal-1.16.0.2: Missing dependencies on foreign libraries:
* Missing (or bad) header file: gd.h
* Missing C libraries: gd, expat




Failed to install gd-3000.7.3
cabal-1.16.0.2: Error: some packages failed to install:
gd-3000.7.3 failed during the configure step.  The exception was: ExitFailure 1








Upon further inquiries via google,  I found somewhere the following :





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 thought I did this already.  


But, apparently, I did something wrong??

Hi,

I just started working with Haskell

Running it on a RHEL linux operating system

I was able to download and install it,  along with libraries and packages  (or, 
at least, what I thought were the libraries and packages)

But, when I try to run a simple script, I keep getting the error :   "Could not 
find module XXXXXX"..............

I understand what this error means ---- there is a package/library missing.

I tried using the "Cabal Update"  command,  but this did not solve the problem.

So, I am now fixing this problem the primitive way, as follows :

(a)  I use Google to first find out what the missing module is

(b)  then, based on what google says, I am able to determine the name of the 
actual package that needs to be installed

(c)  I use  "Cabal Install"  to install the package

(d)  I try to run the script again

(e)  I get the same error, but this time, it cannot find a different module

(f)  I go back to Google to locate the missing module


etc, etc, etc, etc


Obviously, this is as slow as it is ridiculous...............
especially when one considers that there are probably hundreds of these 
modules/packages

And, now, I've come up against a module/package,  which I am unable to locate in 
Google.  It's missing from my installation, and Google does not know what it is,  
or where I can find it

Is there any way to simply install ALL required packages???   I thought I 
already did this,  but obviously I missed something

Thanks

Look at the .cabal file for the package you are trying to compile.  It will
list all the dependencies.  If there is no cabal file you are out of luck.
You'll just have to find all the dependencies yourself.

I will say it is a bit easier to find libraries via hayoo (
http://holumbus.fh-wedel.de/hayoo/hayoo.html) than in straight google.

How did you install Haskell?
How did you create your project?

If you haven't done so I'd suggest installing using a package from say
http://www.haskell.org/platform/

That download will install everything you need to get going.
Did you create your project using cabal init?
Maybe copy and paste the error

Hello,

   Try to install haskell platform from red hat repositories. I'm using 
this approach with debian and it works.

Regards,
Emanuel
