Hi, I'm trying to build custom binaries for boost 1.63 using zlib and bzip2 from a local installation rather than the system ones, following the instructions at http://www.boost.org/doc/libs/1_63_0/more/getting_started/unix-variants.html... and http://www.boost.org/doc/libs/1_63_0/libs/iostreams/doc/installation.html but it looks like the build system does not like having the zlib and bzip2 libraries in different folders. Here's what I'm doing to set up the build environment: # create a common directory for zlib and bzip2 mkdir common # build zlib wget http://downloads.sourceforge.net/project/libpng/zlib/1.2.10/zlib-1.2.10.tar.... tar xaf zlib-1.2.10.tar.xz cd zlib-1.2.10/ ./configure make test make install prefix=../common cd .. # build bzip2 wget http://www.bzip.org/1.0.6/bzip2-1.0.6.tar.gz tar xaf bzip2-1.0.6.tar.gz cd bzip2-1.0.6/ make -f Makefile-libbz2_so make test make install PREFIX=../common cp -ar libbz2.so.* ../common/lib/ cd .. # build boost wget https://sourceforge.net/projects/boost/files/boost/1.63.0/boost_1_63_0.tar.b... tar xaf boost_1_63_0.tar.bz2 cd boost_1_63_0/ mkdir boost-build cd tools/build/ ./bootstrap.sh gcc ./b2 install --prefix=../../boost-build cd ../../ export PATH=$PWD/boost-build/bin:$PATH Now, if I tell boost to pick zlib and bzip2 from the common directory with b2 -q \ -d+2 \ --build-dir=build \ --stage-dir=stage \ --disable-icu \ --without-atomic \ --without-chrono \ --without-container \ --without-context \ --without-coroutine \ --without-exception \ --without-graph \ --without-graph_parallel \ --without-locale \ --without-log \ --without-math \ --without-mpi \ --without-random \ --without-wave \ toolset=gcc \ link=shared \ threading=multi \ variant=release \ cxxflags="-std=c++11 -O2" \ -sBZIP2_INCLUDE=../common/include \ -sBZIP2_LIBPATH=../common/lib \ -sZLIB_INCLUDE=../common/include \ -sZLIB_LIBPATH=../common/lib \ stage it works just fine. However, if I try to build boost using two separate directories for bip2 and zlib, with b2 -q \ -d+2 \ --build-dir=build \ --stage-dir=stage \ --disable-icu \ --without-atomic \ --without-chrono \ --without-container \ --without-context \ --without-coroutine \ --without-exception \ --without-graph \ --without-graph_parallel \ --without-locale \ --without-log \ --without-math \ --without-mpi \ --without-random \ --without-wave \ toolset=gcc \ link=shared \ threading=multi \ variant=release \ cxxflags="-std=c++11 -O2" \ -sBZIP2_INCLUDE=../bzip2-1.0.6 \ -sBZIP2_LIBPATH=../bzip2-1.0.6 \ -sZLIB_INCLUDE=../zlib-1.2.10 \ -sZLIB_LIBPATH=../zlib-1.2.10 \ stage the build fails with Performing configuration checks - 32-bit : no - 64-bit : yes - arm : no - mips1 : no - power : no - sparc : no - x86 : yes - symlinks supported : yes - C++11 mutex : yes - Boost.Config Feature Check: cxx11_auto_declarations : yes - Boost.Config Feature Check: cxx11_constexpr : yes - Boost.Config Feature Check: cxx11_defaulted_functions : yes - Boost.Config Feature Check: cxx11_final : yes - Boost.Config Feature Check: cxx11_hdr_mutex : yes - Boost.Config Feature Check: cxx11_hdr_tuple : yes - Boost.Config Feature Check: cxx11_lambdas : yes - Boost.Config Feature Check: cxx11_noexcept : yes - Boost.Config Feature Check: cxx11_nullptr : yes - Boost.Config Feature Check: cxx11_rvalue_references : yes - Boost.Config Feature Check: cxx11_template_aliases : yes - Boost.Config Feature Check: cxx11_thread_local : yes - Boost.Config Feature Check: cxx11_variadic_templates : yes - zlib : yes error: at /home/fwyzard/src/boost/boost_1_63_0/tools/build/src/kernel/modules.jam:107 error: Name clash for '<pbuild/boost/bin.v2/standalone/ac/gcc-5.4.1/release/threading-multi>main.o' error: error: Tried to build the target twice, with property sets having error: these incompatible properties: error: error: - <dll-path>../zlib-1.2.10 <library-path>../zlib-1.2.10 <xdll-path>../zlib-1.2.10 error: - <dll-path>../bzip2-1.0.6 <library-path>../bzip2-1.0.6 <xdll-path>../bzip2-1.0.6 error: error: Please make sure to have consistent requirements for these error: properties everywhere in your project, especially for install error: targets. I get a similar error if I specify only one of bzip and bzip2.

As far as I can tell, this used to work with boost 1.57 - I haven't tried any version in between. Anybody has any suggestions ? Thank you, .Andrea -- Strategy is a system of expedients.
