Build error C3083
by James 26 Jun '17

26 Jun '17

Hi, I am trying to build an application that uses the boost libraries. I am seeing build error C3083 in bind_mf_cc.hpp. The error states: Error C3083 'core': the symbol to the left of a '::' must be a type This is the offending code section : template<class Rt2, class R, class T, class A1> typename boost::enable_if_c<!boost::core::is_same<Rt2,R>::value, _bi::bind_t<Rt2, _mfi::BOOST_BIND_MF_NAME(mf0)<R,T>, typename _bi::list_av_1<A1>::type>>::type BOOST_BIND(R(BOOST_BIND_MF_CC T::*f) (), A1 a1) { typedef _mfi::BOOST_BIND_MF_NAME(mf0)<R, T> F; typedef typename _bi::list_av_1<A1>::type list_type; return _bi::bind_t<Rt2, F, list_type>(F(f), list_type(a1)); } And the line giving the trouble is the line beginning: typename boost::enable_if_c<!boost::core::is_same<Rt2,R>::value, Can anyone help me correct the line to fix this issue please? Thanks.

Hi, there, I am getting internal error C1001 on one of the library header file. it points to the line inside the code: template<class T1, class T2, class...

Hello, I've got Boost 1_53_0 & 1_64_0 working with Qt 5.9 (gcc version 5.3.0) and c++ on Windows 10 - 32 bit. Compiling (without warnings) and running from within Qt Creator. In each version of Boost change "std:auto" to "std::unique". That’s it. What this does with MSVC, I don’t know Regards

Process extension compile issue.
by dinesh kumar 15 Jun '17

15 Jun '17

Hi Team, Greetings for the day. I am currently facing the problem with process extension as documented here <http://www.boost.org/doc/libs/1_64_0/doc/html/boost_process/design.html#boo…> . I am testing the boost 1.64 version macOS, and unable to use the below functionality. void test() { cout << "On Setup" << endl; } int main() { std::function<void(void)> on_st = test; bp::child c2("ls", boost::process::extend::on_setup(on_st)); } *Error: * /usr/local/include/boost/process/detail/handler.hpp:33:9: No matching function for call to object of type 'std::__1::function<void ()>' Would somebody guide me here, please? -- Regards, Dinesh manojadinesh.blogspot.com

[Boost.Program_options] String options parser
by Belcourt, Kenneth 14 Jun '17

14 Jun '17

Hi, We have an executable that uses the program_options library to process command line options like this: $ ./hilbert.x -h -b [ --hilbert ] arg (=1) enable hilbert matrix -e [ --epsilon ] arg (=0.001) roundoff epsilon -h [ --help ] help message -i [ --input-file ] arg process input file -r [ --rank ] arg rank of matrix to construct -t [ --tolerance ] arg (=1e-13) linear tolerance -v [ --inverse ] arg (=0) enable inverse hilbert matrix -w [ --wordsize ] arg (=8) floating-point word size (bytes) and it works great. Now we’re trying to automate some testing and we test our executable with an input file that has hundreds of lines like this: --inverse 1 --tolerance 1e-15 --rank 2 --inverse 1 --tolerance 1e-15 --rank 3 --inverse 1 --tolerance 1e-15 --rank 4 where each line is a separate test case that we run with the specified options. I was looking for a program options parser that can parse a string, so I can read one line of input from this file into a string, and run that test case, that is something like this: // read one line of input from file ifstream ifp; string buffer; while (!ifp.eof() && ifp.good()) { getline(ifp, buffer); // load a set of command line options from this string po::parse_config_file<char>(buffer.c_str(), desc); } The only program option parsers I see are parse_command_line, parse_config_file, and parse_environment. Is there an easy way (without having to construct an argc/argv data structure) to parse a file of program options? — Noel Belcourt

How do I build x64 binaries with Boost source?
by Osman Zakir 12 Jun '17

12 Jun '17

Hi, How do I specify that I want to build 64-bit binaries when I run bootstrap and then invoke b2? I had a linker error saying, “1>libboost_thread-vc141-mt-gd-1_64.lib(thread.obj) : fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'x64'” when I tried to build an ISAPI extension DLL with Wt (just a simple app using the same code as in the “Hello world” example). [Note: I’m just trying out the wtispai.lib/wisapid.lib connector libraries to see how to use them.] Any help would be appreciated. Thanks in advance.

Semantic Compiler Errors (general question)
by James Stortz 12 Jun '17

12 Jun '17

I have included and linked the latest Boost C++ library into my build. I tested the library beforehand. However, when simply including the header files in a C++ actor class in my Unreal game project, I get errors like: Warning Example: Error boost/config/stdlib/dinkumware.hpp(99) : warning C4668: '_HAS_NAMESPACE' is not defined as a preprocessor macro, replacing with '0' for '#if/#elif' Error Examples: Error boost/intrusive/slist.hpp(1926) : error C4003: not enough actual parameters for macro 'check' Error boost/intrusive/slist.hpp(1926) : error C2062: type 'void' unexpected It looks like there is some strict/unsupported semantic issues with the compiler that is being used. How do I fix this? I am on Windows with VS 2017. Sample programs compile fine with just cl /EHsc /I boost_1_64_0 test_game.cpp /link /LIBPATH:"F:\boost_1_64_0\stage\lib" Why would the compiler not work from within Unreal? Thanks, Regards, James

Re: [Boost-users] Beginner Question (Windows MSVC)

So I got it to work by simply renaming the library, but I don't know if that's the proper solution or why. I'm wary that I'll have other issues or that something is off about my installation. (And I do have the LIBPATH correctly typed in the console -- sorry. :D) On Fri, Jun 9, 2017 at 8:26 PM, James Stortz <james.ryan.stortz(a)gmail.com> wrote: > So I got it to work by simply renaming the library, but I don't know if > that's the proper solution or why.
