Subject: Cabal: GHC package on Mac OSX
To: [EMAIL PROTECTED]
Hi Isaac,
I have been experimenting with Haskell Cabal today. Really neat stuff!
I ran into a problem with the generated library archive:
> ld: archive: /usr/local/lib/uust-1.0/libHSuust-1.0.a has no table of
> contents,
> add one with ranlib(1) (can't load from it)
If I do as "ld" suggests and call ranlib on the thing, it works.
I guess this is a Mac OSX specific problem. Maybe you can fix it in
Cabal.
Cheers,
Arthur

No. The generated GHCi package works fine.

Yes:

It is an error, no output file ("prog") is generated.

That's easy:
ranlib /usr/local/lib/uust-1.0/libHSuust-1.0.a

I have no idea. Maybe you can ask Wolgang
Thaller([EMAIL PROTECTED]), he's the Mac OS wizard.

No.
Well, it is good enough for creating the GHCi library. But "ld"
refuses to link, when building an executable.
