Boost Asio SSL can't receive without sending
by 刘焕杰 23 Aug '16

23 Aug '16

Hi, I am using Boost Asio to developed a server, with SSL support. I add async_read_some() function in handshake handler and send handler. Which receiving is OK if I send something to clients, but I can't keep receiving after I stop sending things to client. So I am wondering how can I keep receiving, I know there must be a way to make it, I am new to Asio, can someone help, thanks in advance. ------------------ I won't go

[type_erasure] use of typeid_of with reference any
by Joaquin M López Muñoz 23 Aug '16

23 Aug '16

Boost.TypeErasure docs say template<typename Concept, typename T> const std::type_info & typeid_of(const any< Concept, T > & arg); [...] Requires: Concept includes typeid_<T>. T is a non-reference, CV-unqualified placeholder. which, if my literal reading is right, means that you can't use typeid_of on, say, any<typeid_<>,_self&>, yet the following compiles on GCC #include <boost/type_erasure/any.hpp> #include <boost/type_erasure/builtin.hpp> #include <boost/type_erasure/typeid_of.hpp> #include <iostream> using namespace boost::type_erasure; int main() { int x=0; any<boost::mpl::vector<typeid_<>,relaxed>,_self&> a=x; std::cout<<typeid_of(a).name()<<"\n"; } and correctly outputs the name of the "int" type. Is this a bug in the docs or am I missing something? Thank you, Joaquín M López Muñoz

How to build Boost agianst specific version of openSSL
by ramonpadilla1＠yahoo.co.uk 22 Aug '16

22 Aug '16

My machine is a Mac with OS X El Capitan installed.Using Homebrew I have installed openssl 1.0.2h_1 but it does not allow it to be linked to usr/local.openssl version -a returns:OpenSSL 0.9.8zh 14 Jan 2016 built on: Feb 4 2016 platform: darwin64-x86_64-llvm options: bn(64,64) md2(int) rc4(ptr,char) des(idx,cisc,16,int) blowfish(idx) compiler: -arch x86_64 -fmessage-length=0 -pipe -Wno-trigraphs -fpascal-strings -fasm-blocks -O3 -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -DL_ENDIAN -DMD32_REG_T=int -DOPENSSL_NO_IDEA -DOPENSSL_PIC -DOPENSSL_THREADS -DZLIB -mmacosx-version-min=10.6 OPENSSLDIR: "/System/Library/OpenSSL"which openssl returns /usr/bin/openssl.I want to build Boost but I understand from the answer posted to this question that Boost will use the openssl version provided by the system.How do I force the boost build to use the version of openssl I have installed via Homebrew?

Hi Radu, yes, I have called run() on the ioservice. And I still can't figure out why, do I need to keep sending things to client?

[math] Undefined reference to promote_args
by Florian Lindner 18 Aug '16

18 Aug '16

Hello, when compiling a file that uses float_distance from #include <boost/math/special_functions/relative_difference.hpp> I get a linking error: undefined reference to `boost::math::tools::promote_args<double, double, float, float, float, float>::type boost::math::float_distance<double, double>(double const&, double const&)' I try to add all boost_math libs I could find, but none helped: -lboost_system -lboost_filesystem -lboost_math_tr1 -lboost_math_c99 -lboost_math_c99 Since float_distance is not a C99 / TR1 function, should'nt boost.math work as header only? What is the problem here? Thanks, Florian

Custom build of Python3 not picked up by Boost.Build
by Matthieu Brucher 17 Aug '16

17 Aug '16

Hi, As I need a build of Python3 compatible with VS2012, I built it from scratch and installed it in a _INSTALL folder, following a tutorial online. Now, I want to use that Python3 with Boost.Python, so I did this in my use-config.jam: using python : 3.4 : D:/Tools/Python-3.4.5/_INSTALL/python.exe : D:/Tools/Python-3.4.5/_INSTALL/include : D:/Tools/Python-3.4.5/_INSTALL/libs ; And then: .\bootstrap.bat --with-python=D:\Tools\Python-3.4.5\_INSTALL --with-python-version=3.4 --python-buildid=3 which failed. The includes are found properly, but the link is floawed: LINK : fatal error LNK1104: cannot open file 'python34.lib' The library is in D:/Tools/Python-3.4.5/_INSTALL/libs, but could not be found according to the log. Also, something strange: D:\Tools\boost_1_60_0\tools\build\src\engine>.\bootstrap\jam0 -f build.jam --toolset=vc14 "--toolset-root=C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\..\..\VC\ " --with-python=D:\Tools\Python-3.4.5\_INSTALL --with-python-version=3.4 --python-buildid=3 The retrieved toolset is wrong, as explicitely asked for VS2012 aka 11.0 int he user-config.jam and I'm running it from a VS2012 x64 native tools command prompt. Couldn't find any help online, so the best is to ask the Boost community!
