How to build Boost with Clang/libc++ and NOT link against libstdc++?
by Deniz Bahadir 20 Jan '17

20 Jan '17

Hi guys, I am struggling with building the Boost (1.58.0) libraries with Clang (3.8) and libc++ (on Ubuntu 16.04). I am able to build the Boost libraries using Clang and flags "-std=c++14 -stdlib=libc++", however, I noticed that several libraries are still linked against GCC's standard-library "libstdc++". I then tried adding the flag "-lc++abi" (later I tried "-Wl,-lc++abi") to Boost.Build options "cxxflags" and "linkflags" to explicitly link against "libc++abi". With no luck. Several boost-libraries are still linked against "libstdc++". Does anyone know how and why this link-dependency gets added and how to get rid of them? Does it come in through some other link-dependencies? At least none of them seem to link to "libstdc++"? The Boost shared-libraries that link to "libstdc++" are: libboost_chrono-clang38-mt-1_58_0.so.1.58.0 libboost_context-clang38-mt-1_58_0.so.1.58.0 libboost_coroutine-clang38-mt-1_58_0.so.1.58.0 libboost_date_time-clang38-mt-1_58_0.so.1.58.0 libboost_filesystem-clang38-mt-1_58_0.so.1.58.0 libboost_graph-clang38-mt-1_58_1.so.0.58.0 libboost_iostreams-clang38-mt-1_58_0.so.1.58.0 libboost_locale-clang38-mt-1_58_0.so.1.58.0 libboost_log-clang38-mt-1_58_0.so.1.58.0 libboost_log_setup-clang38-mt-1_58_0.so.1.58.0 libboost_math_tr1-clang38-mt-1_58_0.so.1.58.0 libboost_math_tr1f-clang38-mt-1_58_0.so.1.58.0 libboost_math_tr1l-clang38-mt-1_58_0.so.1.58.0 libboost_program_options-clang38-mt-1_58_0.so.1.58.0 libboost_python-clang38-mt-1_58_0.so.1.58.0 libboost_random-clang38-mt-1_58_0.so.1.58.0 libboost_regex-clang38-mt-1_58_0.so.1.58.0 libboost_signals-clang38-mt-1_58_0.so.1.58.0 libboost_thread-clang38-mt-1_58_0.so.1.58.0 libboost_timer-clang38-mt-1_58_0.so.1.58.0 libboost_unit_test_framework-clang38-mt-1_58_0.so.1.58.0 libboost_wave-clang38-mt-1_58_0.so.1.58.0 The once that are fine and do not link against "libstdc++" are: libboost_atomic-clang38-mt-1_58_0.so.1.58.0 libboost_container-clang38-mt-1_58_0.so.1.58.0 libboost_math_c99-clang38-mt-1_58_0.so.1.58.0 libboost_math_c99f-clang38-mt-1_58_0.so.1.58.0 libboost_math_c99l-clang38-mt-1_58_0.so.1.58.0 libboost_serialization-clang38-mt-1_58_0.so.1.58.0 libboost_system-clang38-mt-1_58_0.so.1.58.0 libboost_wserialization-clang38-mt-1_58_0.so.1.58.0 Interestingly, all libraries are also linked against "libc++abi" except for: libboost_atomic-clang38-mt-1_58_0.so.1.58.0 libboost_container-clang38-mt-1_58_0.so.1.5 For completeness, my build-command is this: cd /home/jenkins/workspace/Pipeline_Boost/sources/boost_1_58_0 LINK_LIBCXXABI="-Wl,-lc++abi" COMMON_COMPILER_FLAGS="-m64 -fpic -fdiagnostics-color=always -O3" CFLAGS="$COMMON_COMPILER_FLAGS" CXXFLAGS="$COMMON_COMPILER_FLAGS -std=c++14 -stdlib=libc++ -isystem/usr/include/libcxxabi $LINK_LIBCXXABI" CC=/usr/bin/clang-3.8 CXX=/usr/bin/clang++-3.8 /home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost-build/b2 -j1 -q \ --build-dir=/home/jenkins/workspace/Pipeline_Boost@3/clang38/build/boost \ --build-type=minimal --layout=versioned address-model=64 install \ --prefix=/home/jenkins/workspace/Pipeline_Boost@3/clang38/installed/opt/BENOCS/clang38 \ --libdir=/home/jenkins/workspace/Pipeline_Boost@3/clang38/installed/opt/BENOCS/clang38/lib/x86_64-linux-gnu \ dll-path==/opt/BENOCS/clang38/lib/x86_64-linux-gnu \ toolset=clang-3.8 \ cflags="$CFLAGS" CXXFLAGS="$CXXFLAGS" \ linkflags="-Wl,--as-needed $LINK_LIBCXXABI" For the environment-variable LINK_LIBCXXABI I tried "-lc++abi" as well and also tried providing it only in the cxxflags or the linkflags or both (as above). I would be happy, if anyone could explain that behavior or could even provide a workaround/fix for me, so that "libstdc++" is no longer linked. Thanks, Deniz PS: BTW, does anyone know if it is correct, that shared libraries (in general) that are linked against "libc++abi" do always also link to "libgcc_s"?

Fwd: Boost coroutine/context libraries

--------------- Forwarded message (begin) Subject: Boost coroutine/context libraries From: Gregory Laird <glaird(a)northgatebowl.com> Date: Tue, 17 Jan 2017 17:10:57 -0800 Newsgroup: gmane.comp.lib.boost.user I am trying to write a cooperative task scheduler in c++ and I have discovered the boost context and coroutine libraries. I have written these sorts of schedulers many times in assembly language so I appreciate the issues in the methodology. I have written lots of c code but am less versed in c++. I have been trying to find some straightforward examples of the libraries use without a lot of extraneous c++ language elements (e.g. binds, lambdas, etc.). I did find one example http://stackoverflow.com/questions/11716291/boost-context-class that is very nice, but it will not compile now with the current boost library. I get an error saying that boost::context::fcontext_t has been removed from the public api. Could someone direct me to some examples that demonstrate the context or coroutine functionality that would be easier to understand. I want to write a scheduler that is very similar to the example listed above where coroutines yeild back to a main caller which then chooses the next coroutine to continue its processing. Thanks. --------------- Forwarded message (end)

I have: #include <boost/filesystem/path.hpp> #include <boost/filesystem/operations.hpp> boostPath = canonical(boostPath); While I debug it is OK, but when I run debug or release x64 program standalone from cmd - it abort at canonical without any info.

Multiprecision -- cubing a number gives unexpected result
by Craig Henderson 19 Jan '17

19 Jan '17

Hello, I am new to Boost.Multiprecision and have come across a result that I cannot understand. I have the following code to calculate the sum of three cubes, using bigint_t = boost::multiprecision::mpz_int; bigint_t a = 2220422932; bigint_t b = 2218888517; b = -b; bigint_t c = 283059965; c = -c; std::cout << '(' << a << ")^3+(" << b << ")^3+(" << c << ")^3 = "; bigint_t a1 = a * a * a; bigint_t b1 = b * b * b; bigint_t c1 = c * c * c; std::cout << '(' << a1 << ")+(" << b1 << ")+(" << c1 << ") = "; std::cout << bigint_t(a1+b1+c1) << '\n'; and it produces the correct result (2220422932)^3+(-2218888517)^3+(-283059965)^3 = (10947302325566084787191541568)+(-10924622727902378924946084413)+(-22679597663705862245457125) = 30 However, if I use this implementation, with a,b and c assigned the result of the multiplication, a = a * a * a; b = b * b * b; c = c * c * c; std::cout << '(' << a << ")+(" << b << ")+(" << c << ") = "; std::cout << bigint_t(a+b+c) << '\n'; ... I get a very strange result: (24307641127223864542936438774018437376)+(24240519923499804093545671548118385521)+(6419686120902663137493915211500625) = 48554580736844571299619604237348323522 What is going on? Is this an invalid use of the multiplication that I have missed? I get the same result with cpp_int and gmp; using bigint_t = boost::multiprecision::cpp_int; using bigint_t = boost::multiprecision::mpz_int; I'm using g++ (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609, Boost 1.58 Many thanks Craig

1.63.0: diffenre package with the same version
by Ivan Kabaivanov 15 Jan '17

15 Jan '17

Hi, first time poster here. I've been compiling boost from source for about 8 years now. I download the packages from sourceforge.net (https://sourceforge.net/projects/boost/files/boost/1.63.0/) Lately (last few releases) I notice a troubling trend -- the same package, say boost_1_63_0.tar.bz2 will have a different md5 hash if downloaded again a few weeks after being downloaded for the first time. Case in point: boost_1_63_0.tar.bz2, downloaded around Fri Dec 30 17:11:50 2016 +0200 (GMT+2) had md5 hash d17537e28aa2131fa192ce2870ce72a3. The very same file, dowloaded today (January 15, 2017) has a new md5 hash: 1c837ecd990bb022d07e7aab32b09847. What's more troubling is that a cursory comparison of the two files' contents reveals differences. To begin with, the old package had 53599 files, while the new one has 53655. Further, files that are present in both packages have small differences. $ diff -Naur ../../OLD/boost_1_63_0/./libs/numeric/odeint/doc/html/boost/numeric/odeint/base_tag.html ../../NEW/boost_1_63_0/./libs/numeric/odeint/doc/html/boost/numeric/odeint/base_tag.html--- ../../OLD/boost_1_63_0/./libs/numeric/odeint/doc/html/boost/numeric/odeint/base_tag.html 2016-12-29 17:12:21.000000000 +0200+++ ../../NEW/boost_1_63_0/./libs/numeric/odeint/doc/html/boost/numeric/odeint/base_tag.html 2016-12-22 14:47:46.000000000 +0200@@ -7,7 +7,7 @@ <link rel="home" href="../../../index.html" title="Chapter 1. Boost.Numeric.Odeint"> <link rel="up" href="../../../header/boost/numeric/odeint/stepper/stepper_categories_hpp.html" title="Header <boost/numeric/odeint/stepper/stepper_categories.hpp>"> <link rel="prev" href="dense_output_stepper_tag.html" title="Struct dense_output_stepper_tag">-<link rel="next" href="base_tag_stepp_idp64335824.html" title="Struct base_tag<stepper_tag>">+<link rel="next" href="base_tag_stepp_idp34699008.html" title="Struct base_tag<stepper_tag>"> </head> <body bgcolor="white" text="black" link="#0000FF" vlink="#840084" alink="#0000FF"> <table cellpadding="2" width="100%"><tr>@@ -20,7 +20,7 @@ </tr></table> <hr> <div class="spirit-nav">-<a accesskey="p" href="dense_output_stepper_tag.html"><img src="../../../../../../../../doc/src/images/prev.png" alt="Prev"></a><a accesskey="u" href="../../../header/boost/numeric/odeint/stepper/stepper_categories_hpp.html"><img src="../../../../../../../../doc/src/images/up.png" alt="Up"></a><a accesskey="h" href="../../../index.html"><img src="../../../../../../../../doc/src/images/home.png" alt="Home"></a><a accesskey="n" href="base_tag_stepp_idp64335824.html"><img src="../../../../../../../../doc/src/images/next.png" alt="Next"></a>+<a accesskey="p" href="dense_output_stepper_tag.html"><img src="../../../../../../../../doc/src/images/prev.png" alt="Prev"></a><a accesskey="u" href="../../../header/boost/numeric/odeint/stepper/stepper_categories_hpp.html"><img src="../../../../../../../../doc/src/images/up.png" alt="Up"></a><a accesskey="h" href="../../../index.html"><img src="../../../../../../../../doc/src/images/home.png" alt="Home"></a><a accesskey="n" href="base_tag_stepp_idp34699008.html"><img src="../../../../../../../../doc/src/images/next.png" alt="Next"></a> </div> <div class="refentry"> <a name="boost.numeric.odeint.base_tag"></a><div class="titlepage"></div>@@ -45,7 +45,7 @@ </tr></table> <hr> <div class="spirit-nav">-<a accesskey="p" href="dense_output_stepper_tag.html"><img src="../../../../../../../../doc/src/images/prev.png" alt="Prev"></a><a accesskey="u" href="../../../header/boost/numeric/odeint/stepper/stepper_categories_hpp.html"><img src="../../../../../../../../doc/src/images/up.png" alt="Up"></a><a accesskey="h" href="../../../index.html"><img src="../../../../../../../../doc/src/images/home.png" alt="Home"></a><a accesskey="n" href="base_tag_stepp_idp64335824.html"><img src="../../../../../../../../doc/src/images/next.png" alt="Next"></a>+<a accesskey="p" href="dense_output_stepper_tag.html"><img src="../../../../../../../../doc/src/images/prev.png" alt="Prev"></a><a accesskey="u" href="../../../header/boost/numeric/odeint/stepper/stepper_categories_hpp.html"><img src="../../../../../../../../doc/src/images/up.png" alt="Up"></a><a accesskey="h" href="../../../index.html"><img src="../../../../../../../../doc/src/images/home.png" alt="Home"></a><a accesskey="n" href="base_tag_stepp_idp34699008.html"><img src="../../../../../../../../doc/src/images/next.png" alt="Next"></a> </div> </body> </html> I know, these are trivial differences.

Problems Building Boost 1.63 on Solaris 11.3 x86 with Oracle Developer Studio12.5
by Shawn Firth 14 Jan '17

14 Jan '17

Ladies and Gentlemen, We have been using Boost on Windows and HP-UX for over five years. Recently I have been attempting to build Boost 1.63 on Solaris 11.3 x86 with Oracle Developer Studio12.5. I started with: ./bootstrap.sh --prefix=/export/home/me/boost_1_63_0 -libdir=/export/home/me/boost_1_63_0/lib --with-toolset=sun ...and that is where I still am. I have been trying every b2 option/configuration that I can file via Google to get Boost 1.63, both with and without C++11, and I am striking out. The Boost documentation is very terse on Sun builds, however the Boost 1.63 release notes say it has been tested for SunOS: Oracle Solaris Studio 12.5 and Oracle Solaris Studio, C++11 12.5. Here's all that the Boost 1.64 doco has to say about Sun builds: sun Oracle Only very recent versions are known to work well with Boost. Note that the Oracle/Sun compiler has a large number of options which effect binary compatibility: it is vital that the libraries are built with the same options that your appliction will use. In particular be aware that the default standard library may not work well with Boost, unless you are building for C++11. The particular compiler options you need can be injected with the b2 command line options cxxflags=``and ``linkflags=. For example to build with the Apache standard library in C++03 mode use b2 cxxflags=-library=stdcxx4 linkflags=-library=stdcxx4. http://www.boost.org/doc/libs/1_63_0/more/getting_started/unix-variants.html Sun Studio The sun module supports the Sun Studio<http://developers.sun.com/sunstudio/index.jsp> C++ compilers for the Solaris OS. The module is initialized using the following syntax: using sun : [version] : [c++-compile-command] : [compiler options] ; This statement may be repeated several times, if you want to configure several versions of the compiler. If the command is not specified, Boost.Build will search for a binary named CC in /opt/SUNWspro/bin and in PATH. When using this compiler on complex C++ code, such as the Boost C++ library<http://boost.org/>, it is recommended to specify the following options when intializing the sun module: -library=stlport4 -features=tmplife -features=tmplrefstatic See the Sun C++ Frontend Tales<http://blogs.sun.com/sga/entry/command_line_options> for details. The following options can be provided, using <option-name>option-value syntax: cflags Specifies additional compiler flags that will be used when compiling C sources. cxxflags Specifies additional compiler flags that will be used when compiling C++ sources. compileflags Specifies additional compiler flags that will be used when compiling both C and C++ sources. linkflags Specifies additional command line options that will be passed to the linker. Starting with Sun Studio 12, you can create 64-bit applications by using the address-model=64 property. http://www.boost.org/build/doc/html/bbv2/reference/tools.html#bbv2.referenc… Can someone provide me with the user-config.jam and b2 options so that I can successfully build Boost 1.63 on Solaris 11.3 x86 with Oracle Developer Studio12. 3, 4, or 5? Failing user-config.jam and b2 options for Solaris 11 on x86, can you provide me with user-config.jam and b2 options for Solaris 11 on SPARC with Oracle Developer Studio12.3, 4, or 5? Thank you for your time...

boost 1.63 fails to build with zlib and bzip2 in different directories
by Andrea Bocci 14 Jan '17

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.htm… 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.… 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.

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.

Hi there! There were attempts at building 1.62.0 with the new v141 toolset of MSVC and some success. Did 1.63 make any progress in this regard? I see that the final release still builds libraries labeled v140 even when using a dev cmd prompt with the new compiler. Cheers, Máté
