you can see that the build system is in fact emitting the correct command for linking, however it is apparently being ignored on PPC "g++" -dynamiclib -Wl,-single_module -install_name "libboost_thread.dylib" -o "bin.v2/libs/thread/build/darwin-4.2.1/ release/architecture-combined/macosx-version-min-10.4/threading-multi/ libboost_thread.dylib" "bin.v2/libs/thread/build/darwin-4.2.1/release/ architecture-combined/macosx-version-min-10.4/threading-multi/pthread/ thread.o" "bin.v2/libs/thread/build/darwin-4.2.1/release/architecture- combined/macosx-version-min-10.4/threading-multi/pthread/exceptions.o" "bin.v2/libs/thread/build/darwin-4.2.1/release/architecture-combined/ macosx-version-min-10.4/threading-multi/pthread/once.o" - headerpad_max_install_names -mmacosx-version-min=10.4 -Wl,-dead_strip - no_dead_strip_inits_and_terms -arch i386 -arch ppc -force_cpusubtype_ALL malkier:lib davec$ otool -f -v ./libboost_thread.dylib Fat headers fat_magic FAT_MAGIC nfat_arch 2 architecture i386 cputype CPU_TYPE_I386 cpusubtype CPU_SUBTYPE_I386_ALL capabilities 0x0 offset 4096 size 119460 align 2^12 (4096) architecture ppc7400 cputype CPU_TYPE_POWERPC cpusubtype CPU_SUBTYPE_POWERPC_7400 capabilities 0x0 offset 126976 size 124024 align 2^12 (4096) malkier:lib davec$ so i'm dead in the water on this project. any insight or help that solves this would win you free mac Karaoke software. :) and my gratitude.

well, no i meant bjam
which is the low-level tool used.
is "boost.build" another name for "bjam" ??
It's the name of the complete build system.
so are you saying i can do this?
./bjam macosx-version-min=10.4 architecture=combined linkflags="- force_cpusubtype_ALL" install
Of course.
Be sure to clean the libs beforehand because Boost.Build does not track compile and link options. Or add "-a" to force a complete rebuild.
i tried doing this:
i completely wiped my boost tree. oops but i did not wipe the usr local/lib hmmm. but it DID get updated (cre / mod date is today)
then did this:
./bjam macosx-version-min=10.4 architecture=combined linkflags="- force_cpusubtype_ALL" install
however, it did NOT set the cpu type. when i do this you can see:
If you add -a -n to the above commands -- without cleaning anything, or doing other actions -- you should see the compiler and linker commands that are executed. Does the link command include the above flag? If so, then presumably the option does not do what you expect. Should it maybe be passed to compiler instead?
