Hi all,
I am trying to compile boost on Mac OS X 10.9.5 for 32 and 64 bit.
I am using the following command:
  
    ./b2 link=static threading=multi architecture=x86 address-model=32_64

I get the following error message:
   
    darwin.compile.c++.pch bin.v2/libs/math/build/darwin-4.2.1/release/address-model-32_64/architecture-x86/link-static/threading-multi/../src/tr1/pch.hpp.gch
    clang: error: cannot use 'precompiled-header' output with multiple -arch options

        "g++" -x c++-header -O3 -finline-functions -Wno-inline -Wall -gdwarf-2 -fexceptions -arch i386 -arch x86_64  -DBOOST_ALL_NO_LIB=1 -DBOOST_BUILD_PCH_ENABLED -DNDEBUG -I"." -I"libs/math/src/tr1" -c -o "bin.v2/libs/math/build/darwin-4.2.1/release/address-model-32_64/architecture-x86/link-static/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/address-model-32_64/architecture-x86/link-static/threading-multi/../src/tr1/pch.hpp.gch...


Then 144 targets are skipped.

Does anyone knows how to fix this?

Thanks in advance
Kevin
