[Boost-users] building Boost on MacOS: maybe I'm just too stupid but...

Aloha,

I just tried to build Boost 1.34.1 fat (a.k.a. Universal) libraries  
for MacOS X. This is what happened:

I created the following ~/user-config.jam file in order to build  
Universal libs:

using darwin
        :                # version
        :                # command not specified ? use default
        :                # options
      <compileflags>"-O -g -isysroot /Developer/SDKs/MacOSX10.4u.sdk - 
arch i386 -arch ppc"
      <linkflags>"-arch i386 -arch ppc"
;

As described in http://www.boost.org/more/getting_started/unix- 
variants.html 5.1 "Easy Build and Install" I tried to fire up the  
build system like this:

macpro01:/Volumes/Macintosh HD 2/boost_1_34_1 $ ./configure --prefix=/ 
usr/local/

Building Boost.Jam with toolset darwin... ./configure: line 198: cd: / 
Volumes/Macintosh: No such file or directory
./configure: line 1: cd: ./tools/jam/src: No such file or directory
tools/jam/src//bjam
Detecting Python version... 2.5
Detecting Python root... /sw
Unicode/ICU support for Boost.Regex?... not found.
Backing up existing Boost.Build configuration in user-config.jam.2
Generating Boost.Build configuration in user-config.jam...
Generating Makefile...

It seems that configure has a problem with "Macintosh HD 2" as a  
directory name...

$ make
make: *** No targets specified and no makefile found.  Stop.

WHATEVER - there's still the 5.2 "custom" way to build the boost libs:

$ cd ~/boost_1_34_1/tools/jam/src
$ ./build.sh
$ cp bin.macosxx86/bjam ../../../

$ cd ~/boost_1_34_1/
$ ./bjam --prefix=/usr/local
$ sudo ./bjam install

... 1 hour later everything _seems_ to be fine:

$ file /usr/local/lib/libboost_filesystem-1_34_1.dylib
/usr/local/lib/libboost_filesystem-1_34_1.dylib: Mach-O universal  
binary with 2 architectures
/usr/local/lib/libboost_filesystem-1_34_1.dylib (for architecture  
i386): Mach-O dynamically linked shared library i386
/usr/local/lib/libboost_filesystem-1_34_1.dylib (for architecture  
ppc):  Mach-O dynamically linked shared library ppc

That's exactly what I wanted. But... THIS is really strange (test.cpp  
is the regex example from the install manual):

$ g++ test.cpp  -I/usr/local/include/boost-1_34_1/ -L/usr/local/lib/ - 
lboost_regex-mt-d-1_34_1

$ ./a.out
dyld: Library not loaded: /var/tmp//ccMlDtbZ.out
   Referenced from: /Volumes/Macintosh HD 2/./a.out
   Reason: image not found
Trace/BPT trap

WHAT? I _never_ referenced a library called /var/tmp//ccMlDtbZ.out.  
What's going on here?

Any help is GREATLY appreciated!

Thanks,
Ole
