I see tutorial sample: https://www.boost.org/doc/libs/1_67_0/libs/spirit/example/qi/mini_xml3.cpp <https://www.boost.org/doc/libs/1_67_0/libs/spirit/example/qi/mini_xml3.cpp> on_error<fail> ( xml , std::cout << val("Error!

If I write _2 instead _4, is compiler error. -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Users-f2553780.html

[numeric/interval.hpp] compilation on clang++ vs g++
by M B 27 Jun '18

27 Jun '18

This may be a somewhat newbie question.This is cross-posted on stack exchange before I found this list. (https://stackoverflow.com/questions/51062374/different-behavior-with-enable…) I'm having trouble compiling the following piece of boost-based code: ***** #include <boost/numeric/interval.hpp> #include <complex> int main(){ std::complex<boost::numeric::interval<double> > my_interval(1,1); my_interval *= my_interval; return 0;} ***** When I compile using g++ (MacPorts gcc5 5.5.0_1), I get no compilation errors (g++ -std=c++14 main.cpp). When I compile using clang++ (Apple LLVM version 8.1.0 (clang-802.0.38)), I get compilation errors (clang++ -std=c++14 main.cpp). Summarizing the error, it appears that an enable_if in cmath (line 424: std::enable_if<std::is_arithmetic<_A1>::value, bool>::type) is preventing isnan from being defined for boost::numeric::interval<double> (at least in clang++). Am I doing something wrong or is there a work around? I realize that this might be more of a std::complex question than a boost question, but since it involves boost, I thought that I'd ask here. Thank you. The full and complete error is below. ***** Full and Complete Error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/complex:599:9: error: no matching function for call to 'isnan' if (isnan(__x) && isnan(__y)) ^~~~~/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/complex:312:27: note: in instantiation of function template specialization 'std::__1::operator*<boost::numeric::interval<double, boost::numeric::interval_lib::policies<boost::numeric::interval_lib::rounded_math<double>, boost::numeric::interval_lib::checking_strict<double> > > >' requested here *this = *this * complex(__c.real(), __c.imag()); ^main.cpp:6:15: note: in instantiation of function template specialization 'std::__1::complex<boost::numeric::interval<double, boost::numeric::interval_lib::policies<boost::numeric::interval_lib::rounded_math<double>, boost::numeric::interval_lib::checking_strict<double> > > >::operator*=<boost::numeric::interval<double, boost::numeric::interval_lib::policies<boost::numeric::interval_lib::rounded_math<double>, boost::numeric::interval_lib::checking_strict<double> > > >' requested here my_interval *= my_interval; ^/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/cmath:424:25: note: candidate template ignored: disabled by 'enable_if' [with _A1 = boost::numeric::interval<double, boost::numeric::interval_lib::policies<boost::numeric::interval_lib::rounded_math<double>, boost::numeric::interval_lib::checking_strict<double> > >]typename std::enable_if<std::is_arithmetic<_A1>::value, bool>::type

[Test] Test executable crashes always
by Nate Widmyer 26 Jun '18

26 Jun '18

Hello, I've made some unit tests with boost test before without issue, but on my latest rather ordinary test, I've been able to get Boost test to crash the executable in debug and release mode when boost test is making a report before terminating. test_exe.exe!boost::unit_test::framework::get(unsigned long id, boost::unit_test::test_unit_type t) Line 1388 C++ test_exe.exe!boost::unit_test::framework::get<boost::unit_test::test_unit>(unsigned long id) Line 208 C++ test_exe.exe!boost::unit_test::results_reporter::make_report(boost::unit_test::report_level l, unsigned long id) Line 175 C++ test_exe.exe!boost::unit_test::unit_test_main(boost::unit_test::test_suite *(*)(int, char * *) init_func, int argc, char * * argv) Line 235 C++ test_exe.exe!main(int argc, char * * argv) Line 287 C++ That's the default report_level of 'confirm' If I use report_level=short or detailed, I get a similar crash: test_exe.exe!boost::unit_test::framework::get(unsigned long id, boost::unit_test::test_unit_type t) Line 1388 C++ test_exe.exe!boost::unit_test::framework::get<boost::unit_test::test_suite>(unsigned long id) Line 207 C++ test_exe.exe!boost::unit_test::traverse_test_tree(unsigned long id, boost::unit_test::test_tree_visitor & V, bool ignore_status) Line 365 C++ test_exe.exe!boost::unit_test::results_reporter::make_report(boost::unit_test::report_level l, unsigned long id) Line 185 C++ test_exe.exe!boost::unit_test::unit_test_main(boost::unit_test::test_suite *(*)(int, char * *) init_func, int argc, char * * argv) Line 235 C++ test_exe.exe!main(int argc, char * * argv) Line 287 C++ Here's the get() method: test_unit& get( test_unit_id id, test_unit_type t ) { test_unit* res = impl::s_frk_state().m_test_units[id]; BOOST_TEST_I_ASSRT( (res->p_type & t) != 0, internal_error( "Invalid test unit type" ) ); return *res; } Crash occurs on line 2 of the function. I logged 'res' each time the function is called and many times its valid, but when it runs this one test (by itself or with others), 'res' always ends up being NULL. id seems to always be '1', and t is TUT_ANY (17) if generating a confirmation report or TUT_SUITE (16) if generating a short or detailed report. If I use the option '--report_level=no', then execution does complete fine. I followed through on some process of elimination and it seems to be related to using a fixture? Having no test body still causes the crash. It wasn't until I removed the fixture (and its usage in the body of the test) did the executable not crash. I ensured that I was using the standard fixture model found here: http://www.boost.org/doc/libs/1_64_0/libs/test/doc/html/boost_test/tests_or… OS is Win 7 w/ VS2015 boost is 1.64.0 and was built with: b2 toolset=msvc-14.0 link=static runtime-link=static variant=debug address-model=64 --without-atomic --without-container --without-context --without-coroutine --without-coroutine2 --without-graph --without-graph_parallel --without-iostreams --without-locale --without-math --without-mpi --without-serialization --without-signals --without-type_erasure --without-wave -j4 --abbreviate-paths --without-python -d2 Any help would of something to look at or change would be appreciated.

query regarding parallel algorithms and error message
by ian D Chivers 26 Jun '18

26 Jun '18

I have installed boost to work with Windows Microsoft Visual C++ Cygwin g++ Linux openSuSe I can compile and run test programs On all three versions. However I get the following error messages when trying To call one of the routines in https://www.boost.org/doc/libs/1_67_0/libs/sort/doc/html/sort/parallel.html Here is the cygwin message $ g++ ch3604.cxx ch3604.cxx: In function 'int main()': ch3604.cxx:155:3: error: 'parallel_stable_sort' was not declared in this scope parallel_stable_sort( x.begin() , x.end() ); Here is the Microsoft message C:\document\cpp\examples>cl /EHsc /I "C:\Program Files\boost\boost_1_67_0" -O2 /F 1000000000 ch3604.cxx Microsoft (R) C/C++ Optimizing Compiler Version 19.13.26129 for x64 Copyright (C) Microsoft Corporation. All rights reserved. ch3604.cxx I get a similar message on openSuSe linux. Here is the top part of the source file ##### #include <iostream> #include <algorithm> #include <array> #include <chrono> #include <random> #include <string> #include <boost/sort/sort.hpp> using namespace std; ##### Here is a section of the main program ##### parallel_stable_sort( x.begin() , x.end() ); heading = "Boost sort "; t = timer_01.elapsed(); print_time(heading, t); cout << x[0] << " " << x[nr-1] << endl; ##### I get similar messages when trying to use any of the serial Or parallel routines. The documentation says that I only need to include #include <boost/sort/sort.hpp> To make things available. Any thoughts? Ian Chivers
