Re: cabal: library archive index and Mac OS X?

The index stores a time stamp; if the .a file's modification date is newer, then ld will refuse to load from it until you re-run ranlib. This commonly happens when you first build your .a files and then touch their modification date while installing.

Owch. That's some odd behavior; any links to an explanation for why it works that way? Does this happen on other arches? I don't see a cabal-side workaround... maybe GHC should run ranlib before linking? Is there any drawback to that? Are there any flags to ln to change this behavior? peace, isaac
