[Query]: Statically compile haskell script in nix environment

Help
1

Hi All,

I am trying to compile a haskell script (shake build script) as static (standalone) executable using ghc installed with packages shake. Normal build works but if I use -optl-pthread -optl-static, the build fails where ld is unable to find dependencies.

I am sure I need to create nix-shell with some options and packages to ensure that ld loads those. Some direction would be helpful.

The error log is as follows:

#+begin_src sh

ghc -static -optl-pthread -optl-static -o shakeExample shakeExample.hs

for glibc, you need to add glibc.static to buildInputs to get the statically linked libraries.
