Hey guys, [...] Secondly, the Signals library is not compiling. It's actually not a Signals problem, I think it is a type_traits problem.

I am getting a bunch of strange compile errors, in a boost::type_traits file called: is_base_and_derived.hpp

It looks like there is a template near the top that is the first

This problem stems from the fact that the Metrowerks/mac header debugging.h defines a macro named "check" which conflicts with the function named check defined in the boost headers. Somewhere (in a header wrapping debugging.h?) you need to undefine the "check" macro. - Mat --On Monday, May 05, 2003 10:44 AM -0500 "Stephen W. Carson" wrote: thing

fails. There is a define that goes into an alternate implementation for certain broken compilers. Perhaps CodeWarrior needs to be added to the

of compilers that compiles the "broken compiler" version of the stuff in this header?

We are seeing the same problem trying to use tokenizer.hpp with CodeWarrior on the Mac. Again, errors in is_base_and_derived.hpp on lines that use type_traits. Here's an example: ******** Error : ')' expected (included from: object_traits.hpp:25 compressed_pair.hpp:23 compressed_pair.hpp:20 iterator_adaptors.hpp:124 token_iterator.hpp:15 tokenizer.hpp:21 Book.h:5 Archive.h:4 Archive.cpp:1) is_base_and_derived.hpp line 113 static type_traits::yes_type check (D const volatile *, T); ********

People do seem to be using boost with CodeWarrior on the Mac so surely we just need to tweak the correct setting, right? Somebody? -- Stephen W. Carson DirXion Software St. Louis, MO

I remember at one point it was mentioned that:

function

was deprecated and we were to use either the more universally supported:

functionN

or the cleaner:

function

instead if our compiler supported it.

(Mine doesn't support that last one yet I don't think.)

I am guessing that the oldest syntax was removed and no one has bothered to update the Mac carbon thread implementaton to compile again since then?

That one seems pretty easy to fix - just update to a supported syntax? (I could do this, update to the functionN syntax since that is what my compiler supports. If someone wants me to make and submit the changes to them for inclusion I'd be happy to, if I knew who to send them to...)

Or is there a better/easier workaround?

Sorry, I completely missed this message this first time around. For CodeWarrior you'll need to use the functionN syntax with Boost.Function.

William Kempf is the author/maintainer of Boost.Threads and Mac Murrett contributed the Mac carbon implementation. If you would put together a patch using the appropriate functionN classes it would be appreciated, and I'm sure Bill Kempf would accept it.

Ok. I have already made the changes locally. Do you want me to just send them to Bill then?

Odd. It sounds like a compiler problem, but our Win32 regression tests show Signals working properly with CodeWarrior 8.3. We don't have any regular regression testing for CodeWarrior on the Mac, unfortunately :(

Huh. It is definitely broken - someone else posted about it earlier today, too. Well, I wasn't sure what to do about it. My thought was that CodeWarrior should be using the same "broken compiler workaround" that the other compilers were using. I will send you the change I made. It makes it compile all right but I have no idea if it is the right thing or not... (I don't exactly understand the type-traits source. :-) Are you the right person to take a look at it and (possibly) add it to the Boost sources? -- Bobby --------------------------------------------------------------------- Bobby Thomale Senior Software Developer Inoveon Corporation http://www.inoveon.com/ ---------------------------------------------------------------------
