nix-build, cabal new-build and stack build fails

Trying to build the project, am I missing something?

nix-build
 these derivations will be built:
  /nix/store/sxcvc319gj4zj2d5f5shnx8vsgzxbj6x-run-coveralls.drv
these paths will be fetched (0.00 MiB download, 0.00 MiB unpacked):

[nix-shell:~/NewProjects/Cardano/cardano-shell]$ ./cabal new-build cardano-shell
Warning: No remote package servers have been specified. Usually you would have
one specified in the config file.
Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: cardano-launcher-0.1.0.0 (user goal)
[__1] unknown package: silently (dependency of cardano-launcher)
[__1] fail (backjumping, conflict set: cardano-launcher, silently)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: cardano-launcher, silently

stack build
You cannot have packages and a shell-file filled at the same time in your nix-shell configuration.

@chrissound, regarding the second problem:

1. it's cabal, not ./cabal
2. inside the shell, you'll need to unset CABAL_CONFIG, as a first thing -- before running cabal new-build.

[deepfire]

@chrissound, regarding the first problem -- you're not supposed to use nix-build like that -- as you can see, the top-level default.nix provides several attributes:

~/cardano-shell$ nix repl
Welcome to Nix version 2.3.2. Type :? for help.

nix-repl> f = import ./. {}

nix-repl> f.   # press <TAB> here
f._lib          f.runCoveralls
f.nix-tools     f.shell

But I guess, the chief question is -- why do you want to build cardano-shell`? After all it's just a library, not an end-user executable.

@chrissound, regarding the second problem:

1. it's cabal, not ./cabal
2. inside the shell, you'll need to unset CABAL_CONFIG, as a first thing -- before running cabal new-build.

Many thanks for your help!

Regarding 1 I was using that as the readme mentioned:

Cabal + Nix

There is an option of using just Cabal + Nix as well - use a small utility script (watch out, it's a dot before the cabal!) and work as you would usually if you develop with cabal:

./cabal new-build

cabal new-build still seems to fail but I think it's due to the issue here (https://github.com/NixOS/nixpkgs/issues/55995):

But I guess, the chief question is -- why do you want to build cardano-shell`? After all it's just a library, not an end-user executable.

I was trying to setup a ghci repl / ghcid for a "cardano node" for development to learn more about the project. I assumed cardono-shell was needed as I had issues setting it up otherwise: https://github.com/input-output-hk/cardano-node/issues/441

I'll see if I can finally have this setup with all your pointers, thanks!
