Hi, I have some code in Setup.hs in a cabalized project. I'd like them to be warning-free. But I could not find a way to set -Wall. I tried ghc-options in ~/.cabal/config. But seems like it did not kick in. ``` /bin/ghc --make -fbuilding-cabal-package -odir /home/shida/src/Personal/cairo-core/dist-newstyle/build/x86_64-linux/ghc-8.6.3/cairo-core-1.16.0/setup -hidir /home/shida/src/Personal/cairo-core/dist-newstyle/build/x86_64-linux/ghc-8.6.3/cairo-core-1.16.0/setup -i -i/home/shida/src/Personal/cairo-core/. -optP-include -optP/home/shida/src/Personal/cairo-core/dist-newstyle/build/x86_64-linux/ghc-8.6.3/cairo-core-1.16.0/setup/setup_macros.h -hide-all-packages -no-user-package-db -package-db /home/shida/.cabal/store/ghc-8.6.3/package.db -package-db /home/shida/src/Personal/cairo-core/dist-newstyle/packagedb/ghc-8.6.3 -package-id Cabal-2.4.0.1 -package-id base-4.12.0.0 -package-id directory-1.3.3.0 -package-id filepath-1.4.2.1 -package-id haskell-src-exts-1.21.0-f3e84a9ee8883b0dcaaaaba712d74996854b441aa843a4dedc055c685debcfdb /home/shida/src/Personal/cairo-core/dist-newstyle/build/x86_64-linux/ghc-8.6.3/cairo-core-1.16.0/setup/setup.hs -o /home/shida/src/Personal/cairo-core/dist-newstyle/build/x86_64-linux/ghc-8.6.3/cairo-core-1.16.0/setup/setup -threaded ``` -- 竹密岂妨流水过 山高哪阻野云飞 And for G+, please use magiclouds#gmail.com.
