Cabal build is failing

[HinaMunir-Hm]

Describe the bug
I created the cabal file using command 'cabal init interactive'. But when I am trying to run cabal build it is throwing me errors. I am uncertain but I think this is because either I have created a smart contract using latest plutus playground haskell version or I have done some mistake while creating cabal file.

To Reproduce
Steps to reproduce the behavior:

$cabal init --interactive
What does the package build:
   1) Executable
   2) Library
   3) Library and Executable
Your choice? 3
What is the main module of the executable:

   2) Main.lhs (does not yet exist, but will be created)
   3) Other (specify)
Your choice? [default: Main.hs (does not yet exist, but will be created)] 3
Please specify? nfts-list-contract.hs

 * 4) 2.4    (+ support for '**' globbing)
   5) 3.0    (+ set notation for ==, common stanzas in ifs, more redundant commas, better pkgconfig-depends)
Your choice? [default: 2.4    (+ support for '**' globbing)]

$ cabal v2-build ...

Expected behavior
It should successfully build the cabal file so that I can convert .hs file to .plutus.

Additional context

Hi @HinaMunir-Hm! cabal init only creates a skeleton of a cabal file. You need to manually fill it up with whatever your codebase requires. In this case, I guess you need to add build-depends: ... fields with the packages that are needed (google which missing modules resides in which package or perhaps consult a README or HOWTO for whatever tools you are using). Please let us know how it goes.

[HinaMunir-Hm]

Hello @Mikolaj ,I did but after that I received another error:

[Mikolaj]

Right, I don't want to mislead you and there may be easier way to use this, so please ask on a plutus forum somewhere. However, https://github.com/input-output-hk/plutus-starter suggests you also need a cabal.project file and perhaps more (e.g,. a local git checkout of plutus). Please ask around and let us know so that people searching for plutus on cabal bug-tracker have some answers and links to go by.

[HinaMunir-Hm]

Sure and Thank you

Closing this as not relevant for the cabal development, but you can keep discussing here...
