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?

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

[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!

Boost Units initialize quantity with signaling NaN
by Belcourt, Kenneth 13 Aug '16

13 Aug '16

Hi, I’m trying to find a way to initialize a Boost Unit with a signaling NaN, not just a NaN with the signal cleared. It seems that the only way to initialize a quantity is by multiplying by the unit, and that multiplication clears the signal on the NaN. I know I can just modify the quantity.hpp header and initialize the default constructor val_ member with the signaling NaN, but I was hoping for a cleaner solution. Here’s an example (typed in by hand, not tested): const double s_nan = std::numeric_limits<double>::signaling_NaN(); typedef quantity<si::acceleration, double> acceleration_t; BOOST_UNITS_STATIC_CONSTANT(acceleration_u, acceleration); acceleration_t a(s_nan * acceleration_u); // <— this clears the signal on the NaN Has anyone encountered this or know of a more elegant solution than modifying the quantity.hpp header? — Noel

[Wave] Wave samples and driver utility not building?
by Michael Young 12 Aug '16

12 Aug '16

I have just built boost_1_61_0; I am particularly interested in Boost.Wave at this time. This is my first attempt to build any boost library, or boost in its entirety (all libs). I read and followed the build instructions from the web site, with slight modifications for my environment / purposes: bootstrap.sh 2>&1 | tee build_boost_log.txt sudo ./b2 install 2>&1 | tee -a build_boost_log.txt When it completes, I get the libboost_*.a and .so files in /usr/local/lib, and the source is installed at /usr/local/include/boost, as expected. I do get "...failed updating 58 targets..." in the build output, but my understanding is that's OK - I didn't install optional items like ICU and such. The problem is that I can't find the wave driver (or other sample) utility anywhere. Moreover, when I look at the build log, there is no indication that any of these are being built (even attempted). So I'm wondering if there's a build step / option that I am missing (and/or perhaps I need one of the "optional" 3rd party packages installed?). BTW - I'm building in Ubuntu 14.04 ARM (crouton chroot on Chromebook), with gcc/g++ 4.8.4. I didn't see any indication of any environment problems in the build log.
