   The same thing applies to `cabal configure`, of course, if you're

     

       
667
       
 
       
   building with `cabal-install` instead of Stack.

## Creating statically linked binaries

     

       
670
       
+
       


     

       
671
       
+
       
There are two levels of static linking. The first option is to configure the

     

       
672
       
+
       
build with the Cabal flag `--disable-executable-dynamic`. In Nix expressions,

     

       
673
       
+
       
this can be achieved by setting the attribute:

     

       
674
       
+
       


     

       
675
       
+
       
    enableSharedExecutables = false;

     

       
676
       
+
       


     

       
677
       
+
       
That gives you a binary with statically linked Haskell libraries and

     

       
678
       
+
       
dynamically linked system libraries.

     

       
679
       
+
       


     

       
680
       
+
       
To link both Haskell libraries and system libraries statically, the additional

     

       
681
       
+
       
flags `--ghc-option=-optl=-static --ghc-option=-optl=-pthread` need to be used.

     

       
682
       
+
       
In Nix, this is accomplished with:

     

       
683
       
+
       


     

       
684
       
+
       
    configureFlags = [ "--ghc-option=-optl=-static" "--ghc-option=-optl=-pthread" ];

     

       
685
       
+
       


     

       
686
       
+
       
It's important to realize, however, that most system libraries in Nix are built

     

       
687
       
+
       
as shared libraries only, i.e. there is just no static library available that

     

       
688
       
+
       
Cabal could link!
