Greetings,

Right now I'm developing an app, and I want to use the ncurses library, everything compiles correctly, however when I'm linking, ugly things start to happen:

I'm on Mac OS X Snow Leopard, with Haskell Platform 2010.2.0.0

This is the installation process I'm following, everything runs as expected until trying to build the project with Cabal.

Thanks in advance.

$ brew install ncursesw --universal

Of course, the question is, how can I fix this issue?

Thanks.

You're trying to link a 64-bit library with a 32-bit GHC. Either
upgrade to the new 64-bit GHC installer, or rebuild your libraries
with 32-bit support.

Hi Roman,

This is the problem. You are using OS X 10.6 and Homebrew is building
a 64 bit ncurses. However, GHC generates 32 bit code that expects to
link against a 32 bit ncurses.

In MacPorts, you would solve this by reinstall ncurses with the flag
+universal that instructs MacPorts to build a universal binary
containing both 32 and 64 bit versions of ncurses. I'm not sure what
the equivalent would be for homebrew.
