"cabal clean" did the trick. Thanks. On Sun, Jul 6, 2014 at 12:54 PM, Carter Schonwald < carter.schonwald@gmail.com> wrote:

Try doing a cabal clean? Also are you setting that for an executable or a library? Only makes sense on an executable

I need to change some runtime options.

I updated the options line in my cabal file: ghc-options: -Wall -fno-warn-orphans -O2 -rtsopts

But when I rebuild and run, it's as though runtime options are still disabled.

C:\johan\Haskell\projects\bio-acai>cabal build .\bio-acai.cabal has been changed. Re-configuring with most recently used options. If this fails, please run configure manually.

C:\johan\Haskell\projects\bio-acai>dist\build\acai\acai.exe +RTS -H128m -K64m *acai.exe: Most RTS options are disabled. Link with -rtsopts to enable them.*

My best guess is that the "ghc-options" line is the wrong place to try to turn on RTS option handling. But what's the right one? -- Johan Larson -- Toronto, Canada
