[Threads-devel] Static build on darwin

Hi all,

I'm having trouble with using Boost.Thread (1.34.1) on Mac OS X  
(10.4.11/ppc/Xcode 2.3).

I have an Xcode project ("BSD command line tool") that links to what  
I believe is the static build of Boost.Thread (libboost_thread-mt- 
d-1_34_1.a). However, when Xcode goes to run the executable, it gives  
the error:

> Running…
> dyld: Library not loaded: bin.v2/libs/thread/build/darwin/debug/ 
> threading-multi/libboost_thread-mt-d-1_34_1.dylib
>   Referenced from: /path/to/my/executable/executablename
>   Reason: image not found
> Program received signal:  "SIGTRAP".

If I run the executable inside an X11 shell, I get a similar error.  
If I add the path to the .dylib to the $DYLD_LIBRARY_PATH environment  
variable, I can run the executable.

Which makes me wonder if somehow this .a file is really a .dylib.

What's also strange is that although the build directories for all  
the other libraries have the same structure (e.g. filesystem/build/ 
darwin/debug/link-static/libboost_filesystem-d-1_34_1.a), the thread  
directory has a threading-multi directory under the link-static  
directory (meaning the file I am trying to link to is in thread/build/ 
darwin/debug/link-static/threading-multi/libboost_thread-mt-d-1_34_1.a).

I'm building all the libraries with bjam 3.1.15 and the command line  
"bjam --toolset=darwin".

FWIW, I'm also using the Boost filesystem library with this  
executable, without any compile, link or run-time errors.

Any help/ideas?

Also: is there any plan to distribute the Boost libraries for Mac OS  
X in a similar way to how they are distributed for Windows (i.e.  
installer that has pre-built library binaries)?
