I'm trying to track down the last warnings in GHC iOS.

We get this waterfall of warnings like:

warning same member name (Types.o) in output file used for input files: /usr/local/ghc-ios-sim/lib/i386-apple-darwin11-ghc-7.7.20130828/base-4.7.0.0/libHSbase-4.7.0.0.a(Types.o) and: /usr/local/ghc-ios-sim/lib/i386-apple-darwin11-ghc-7.7.20130828/base-4.7.0.0/libHSbase-4.7.0.0.a(Types.o) due to use of basename, truncation and blank padding

and

file: /usr/local/ghc-ios-sim/lib/i386-apple-darwin11-ghc-7.7.20130828/base-4.7.0.0/libHSbase-4.7.0.0.a(consUtils.o) has no symbols

when we run libtool to create the static libraries, and I was wondering if anyone had any ideas what causes them so I could start debugging... I can't seem to find much information about the warning.

Here's the output of

i386-apple-darwin11-ghc -staticlib test.'s

where test.hs is simply: main = print "hello world"

and here's the same with -v3

I suppose I can simply suppress the output of libtool when we call it from GHC, but I'd love to find the root cause if we can.

Thanks for any hints!

Cheers
