seems that when i build now (whether with the cmd that worked before, OR if i add the cpusubtype_ALL flag), it always fails: ...found 20863 targets... ...updating 274 targets... darwin.compile.c++.pch bin.v2/libs/math/build/darwin-4.2.1/release/ architecture-combined/macosx-version-min-10.4/threading-multi/../src/ tr1/pch.hpp.gch lipo: can't figure out the architecture type of: /var/folders/h7/ h7zL6S-RECGa80fEMYXIpk+++TI/-Tmp-//ccrtgIl2.out "g++" -x c++-header -O3 -finline-functions -Wno-inline -Wall - mmacosx-version-min=10.4 -dynamic -no-cpp-precomp -gdwarf-2 -arch i386 -arch ppc -fPIC -DBOOST_ALL_NO_LIB=1 -DBOOST_BUILD_PCH_ENABLED - DBOOST_MATH_TR1_DYN_LINK=1 -DNDEBUG -I"." -I"libs/math/src/tr1" -c -o "bin.v2/libs/math/build/darwin-4.2.1/release/architecture-combined/ macosx-version-min-10.4/threading-multi/../src/tr1/pch.hpp.gch" "libs/ math/build/../src/tr1/pch.hpp" ...failed darwin.compile.c++.pch bin.v2/libs/math/build/darwin-4.2.1/ release/architecture-combined/macosx-version-min-10.4/threading- multi/../src/tr1/pch.hpp.gch... ...skipped <pbin.v2/libs/math/build/darwin-4.2.1/release/architecture- combined/macosx-version-min-10.4/threading-multi>assoc_laguerre.o for lack of <pbin.v2/libs/math/build/darwin-4.2.1/release/architecture- combined/macosx-version-min-10.4/threading-multi>../src/tr1/ pch.hpp.gch... ...<a bunch more like above> ...failed updating 4 targets... ...skipped 270 targets...
so it's not building at all. why is it now skipping all targets? sorry i'm kindof a n00b at this
well, no i meant bjam
is "boost.build" another name for "bjam" ??
this is what i use to build boost right now:
./bjam macosx-version-min=10.4 architecture=combined install
so are you saying i can do this?
./bjam macosx-version-min=10.4 architecture=combined linkflags="- force_cpusubtype_ALL" install
?

from Chris again:
Just to follow up on this: there appears to be some odd (or at least non-obvious) behaviour with the linker in Xcode 3.2. If you set the deployment target to 10.3, the resulting architecture ends up as ppc7400 whereas 10.4 will give you ppc. (10.5 and 10.6 give you ppc7400.)
Anyway, if you know your code will work on all PowerPC CPU subtypes, it looks like you could use the -force_cpusubtype_ALL linker flag (I haven't tried it).
again: how do i do this using bjam?
I think you meant "using Boost.Build". There are cflags and linkflags properties that you can specify on the command line. E.g.
linkflags="-force_cpusubtype_ALL"
Does this help?
