Problem with external libraries

[AlexeyRaga]

I am trying to build a project that contains extra dependencies:

from my .cabal file:

  extra-lib-dirs:      /usr/local/lib
  extra-libraries:     rdkafka

Here is the error I have:

$ nix-shell .styx/shell.nix --run "cabal install"                                                                                                      
error: anonymous function at /Users/alexey/src/github/kafka-client/.styx/kafka-client.nix:1:1 called without required argument ‘rdkafka’, at /Users/alexey/src/github/kafka-client/.styx/shell.nix:12:17

Is it that styx doesn't support extra libs or I am doing something wrong?

My styx.yaml:

local-packages:
  kafka-client:
    location: .

stack can build this project without any errors, here is my stack.yaml:

flags: {}
packages:
- '.'
extra-deps:   

resolver: lts-7.13

Please try with the latest patch provided by mpickering. If it does not work try putting rdkafka in the non-haskell-deps section of the styx.yaml file.

(The patch is merged into the trunk btw)

Looking into it, I see that there is a difficulty with external libraries, which must be passed to cabal2nix and re-extracted. For reference, here is the code for glpk-hs in nixpgks:

 "glpk-hs" = callPackage
    ({ mkDerivation, array, base, containers, deepseq, gasp, glpk, mtl
     }:
     mkDerivation {
       pname = "glpk-hs";
       version = "0.5";
       sha256 = "a36ed027a55343864388f6c301279a2fb3ec06e7929f369e386120db7d2c99e9";
       libraryHaskellDepends = [ array base containers deepseq gasp mtl ];
       librarySystemDepends = [ glpk ];
       description = "Comprehensive GLPK linear programming bindings";
       license = stdenv.lib.licenses.bsd3;
     }) {inherit (pkgs) glpk;};
