Different checksums for different SourceForge locations
by Carlos Ferreira 05 Oct '16

05 Oct '16

I'm having some issues in downloading the Boost 1.62 package from the SF servers. It seems that the Eastern US servers checksum values are not matching the rest of the servers, nor the checksum values provided at the Boost.org website. Is there anyone else having the same problem? -- Carlos Miguel Ferreira Researcher at Telecommunications Institute Aveiro - Portugal Work E-mail - cmf(a)av.it.pt Skype & GTalk -> carlosmf.pt(a)gmail.com LinkedIn -> http://www.linkedin.com/in/carlosmferreira

Need help with errors while building boost for clang on android NDK
by Robert Dailey 04 Oct '16

04 Oct '16

I'm using NDK r11 and I'm setting up project-config.jam to build boost using clang + llvm STL. I'm running into a few errors that I do not know how to solve. I will post my config file at the bottom. First problem is that boost does not know where to find tools 'ar' and 'ranlib': clang-linux.archive bin.v2\libs\container\build\clang-linux-android\release\link-static\runtime-link-static\target-os-linux\threading-multi\libboost_container-clang-mt-s-1_61.a '"ar"' is not recognized as an internal or external command, operable program or batch file. '"ranlib"' is not recognized as an internal or external command, operable program or batch file. How can I explicitly specify the NDK path to these executables? Second problem is related to some assembler stuff, I think. I get these errors while compiling boost thread: clang-linux.compile.asm bin.v2\libs\context\build\clang-linux-android\release\link-static\runtime-link-static\target-os-linux\threading-multi\asm\make_i386_ms_pe_gas.o libs\\context\\src\\asm\\make_i386_ms_pe_gas.asm:30:1: error: unknown directive .def _make_fcontext; .scl 2; .type 32; .endef ^ libs\\context\\src\\asm\\make_i386_ms_pe_gas.asm:30:22: error: unknown directive .def _make_fcontext; .scl 2; .type 32; .endef ^ libs\\context\\src\\asm\\make_i386_ms_pe_gas.asm:30:36: error: expected identifier in directive .def _make_fcontext; .scl 2; .type 32; .endef ^ libs\\context\\src\\asm\\make_i386_ms_pe_gas.asm:30:40: error: unknown directive .def _make_fcontext; .scl 2; .type 32; .endef ^ libs\\context\\src\\asm\\make_i386_ms_pe_gas.asm:136:1: error: unknown directive .def __exit; .scl 2; .type 32; .endef ^ How can I solve this? I have no idea at this point. I'm invoking the build using: b2 --without-python threading=multi link=static runtime-link=static toolset=gcc-android target-os=linux threadapi=pthread --stagedir=android stage And my project-config.jam looks like: import option ; option.set keep-going : false ; androidNDKRoot = E:/android/ndk ; androidAbiVer = 4.9 ; androidPlatform = windows-x86_64 ; using clang : android : $(androidNDKRoot)/toolchains/llvm/prebuilt/$(androidPlatform)/bin/clang++ : <compileflags>--sysroot=$(androidNDKRoot)/platforms/android-15/arch-arm <compileflags>-Os <compileflags>-fno-strict-aliasing <compileflags>-O2 <compileflags>-DNDEBUG <compileflags>-g <compileflags>-I$(androidNDKRoot)/sources/cxx-stl/llvm-libc++abi/libcxxabi/include <compileflags>-I$(androidNDKRoot)/sources/cxx-stl/llvm-libc++/libcxx/include <compileflags>-I$(androidNDKRoot)/sources/cxx-stl/llvm-libc++/libs/armeabi-v7a <compileflags>-I$(androidNDKRoot)/sources/android/support/include <compileflags>-DANDROID <compileflags>-D__ANDROID__ <compileflags>-D__arm__ <compileflags>-D_REENTRANT ;

[Boost::asio] Problem using the same io_service with many sockets
by María Victoria Rocha 03 Oct '16

03 Oct '16

Hi all, I have defined an io_service that is used by two sockets, one of them uses tcp, and the other udp. When the callback of this async_read_some is called socket.async_read_some(boost::asio::buffer(readBuffer), boost::bind(&RequestHandler::onRead, shared_from_this(), boost::asio::placeholders::error, boost::asio::placeholders::bytes_transferred)); A udp socket is created with the same io_service and an async_receive_from is called. On the callback of this read operation I try to write to the tcp socket but it captures an exception with message: "unknown exception". When this happens, the client that is listening to the tcp socket, receives "End of file" error. I resolved this problem with an io_service per socket but I would like to use the same io_service. Someone has any idea why this happens? Thanks! Victoria

[Thread] Thread library in boost 1.62 broken with g++ 4.6.3 and -std=c++0x
by Andreas Wehrmann 03 Oct '16

03 Oct '16

Hello folks, I've just wanted to try out the new release and noticed that the Thread library was not building. Assuming this code: #include <boost/thread.hpp> int main( void ) { return 0; } When compiled with -std=c++0x the compilation fails with: In file included from ./boost/boost_1_62_0/boost/exception/detail/exception_ptr.hpp:20:0, from ./boost/boost_1_62_0/boost/exception_ptr.hpp:9, from ./boost/boost_1_62_0/boost/thread/exceptional_ptr.hpp:10, from ./boost/boost_1_62_0/boost/thread/future.hpp:25, from ./boost/boost_1_62_0/boost/thread.hpp:24, from test.cpp:2: ./boost/boost_1_62_0/boost/exception/info.hpp: In instantiation of ‘boost::error_info<boost::tag_original_exception_type, const std::type_info*>’: ./boost/boost_1_62_0/boost/exception/detail/exception_ptr.hpp:95:32: instantiated from here ./boost/boost_1_62_0/boost/exception/info.hpp:66:5: error: ‘class boost::error_info<boost::tag_original_exception_type, const std::type_info*>’ has no member named ‘value_’ ./boost/boost_1_62_0/boost/container/detail/pair.hpp:85:30: warning: ‘boost::container::piecewise_construct’ defined but not used [-Wunused-variable] ./boost/boost_1_62_0/boost/system/error_code.hpp:221:36: warning: ‘boost::system::posix_category’ defined but not used [-Wunused-variable] ./boost/boost_1_62_0/boost/system/error_code.hpp:222:36: warning: ‘boost::system::errno_ecat’ defined but not used [-Wunused-variable] ./boost/boost_1_62_0/boost/system/error_code.hpp:223:36: warning: ‘boost::system::native_ecat’ defined but not used [-Wunused-variable] Compilation works if I don't use -std=c++0x. The exact compiler version is "g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3". I'm aware that g++ 4.6.3 is not among the compilers tested for C++11, but it is for pre-Cpp11; I'm wondering if there is a reason for that which I might not be aware of (any known problems?). Best regards, Andreas
