setting compiler flags to enable all warnings

[berk]

Hi,

I am currently learning haskell and decided to use leksah during the
process. However I couldn't find a way to enable all compiler
warnings. In fact I couldn't find the way to set any compiler flag.
Adding "-Wall" or (say) "--fwarn-name-shadowing" to Package->Edit
Flags->Build flags or Package->Edit Flags->Config flags does not seem
to have any effect. What is the correct way to enable all warnings? I
am using Leksah 0.8.0.8, ghc 6.12.1-12 on ubuntu 10.04 x64 desktop.

Thanks in advance.

You need to tell cabal what program you the option is for...

Package -> Edit Flags -> Build
Add --ghc-option=-Wall

Alternatively you can add it to your cabal package...

Package -> Edit Package -> 1 Compiler -> GHC
Then in the box add -Wall and click the Add button

this is - - ghc-options (no blank between the dashes, but two dashes, which is not clearly visible above)
