I'm trying to build my Yesod web app with GHC 9.0.1 via stack

resolver: nightly-2021-09-02

My application uses PostgreSQL database. There are custom persist fields in my code derived via derivePersistField. Build failing with following error message:

I have PostgreSQL 13 installed via brew.

What is proper setup for PostgreSQL use with persistent on Macs with M1 chip?

Thanks in advance.

CodePudding user response：

I was able to build persistent-postgresql having:

• PostgreSQL installed via brew install postgresql
• GHC v8.10.7 and cabal-install installed via brew install ghc cabal-install
• stack installed via brew install haskell-stack
  (previously I had manually installed stack and upgraded it to latest git version)
• Switched my project resolver to LTS-18.10 to match compiler version to system one (8.10.7)
• Using stack build --system-ghc to build my project with stack.
• or cabal build.

There some drawbacks with this approach:

• brewed stack unable to install any GHC and stuck to use system compiler

  > stack setup
  I don't know how to install GHC for (OSX,AArch64), please install manually

• brew install ghc@9 fails with recommendation to build it from source, which is unsupported and it fails indeed:

  ==> make
