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??
This haskell package provides only library bindings. You need to install original library using system package manager. Regards, Emanuel
