While buliding Boost.Locale 1.48 on darwin:

I'm not yet sure whether this actually causes a problem. I'll update the ticket if so.

[Artyom Beilis]

1. How do you build the library? Using Boost.Build or some custom tool, because I don't understand why libtool is actually used.
2. According to the messages it complains that same file names are used but files are actually different. I don't think it should cause any problems as the sources are different and as long as everything works I don't see a problem with that.

So unless you show some problem (like you can't link with the code) I'll close this ticket as invalid.

1. I built using Boost.Build, by running ./b2 -q --with-date_time --with-filesystem --with-iostreams --with-locale --with-program_options --with-serialization --with-thread --layout=versioned variant=release,debug link=shared,static runtime-link=shared threading=multi address-model=32 architecture=x86 macosx-version=10.6 'cflags=-mmacosx-version-min=10.4' 'linkflags=-mmacosx-version-min=10.4' -sNO_BZIP2=1 stage

2. Fair enough, thanks for clarifying. :)
