Broken link to latest code from old ASIO example
by Kenneth Porter 11 Aug '22

11 Aug '22

The directory structure of ASIO changed a bit and now the website pages of samples in old versions no longer direct to the correct page in the latest version: <https://www.boost.org/doc/libs/1_51_0/doc/html/boost_asio/example/icmp/ping…> I wanted to see how to code a ping so I googled for "boost asio ping" and the top result was for 1.51.0. (I never get the latest code, but I can always jump to an older version and then jump from there to the latest. It just didn't work this time.) … [View More]

Boost.Graph: user survey
by Jeremy Murphy 05 Aug '22

05 Aug '22

Dear Boost.Graph users, I'd like to know how you use Boost.Graph. If you know someone that uses Boost.Graph but is not on this mailing list, please forward this survey to them. The purpose of this survey is to help prioritize work on the areas of Boost.Graph that will have the most benefit to the users. I was planning to make a very sophisticated Google Forms survey, but that is so time consuming. These questions should all be taken in the context of using Boost.Graph. - Which operating … [View More]

Help with a compilation error [Boost/Math]
by Peder Lon Hauge 04 Aug '22

04 Aug '22

Hi, I'm trying to use Boost in order to find values of a 2F3 hypergeometric function. Just to check that I am using the package the correct way, I tried to compile the small test file below (using the example from the pFq docs), with the command $ g++ -o test.exe test.cpp -I /home/peder/boost/boost_1_79_0 As far as I understand, the library is header-only, so I didn't expect the compilation error below. I don't where I've made a mistake, and I'd greatly appreciate any help with figuring out … [View More]

sgn/sign-function
by Gero Peterhoff 31 Jul '22

31 Jul '22

Hi John, i think your sign-function (boost/math/special_functions/sign.hpp) is incomplete. Because the resulttype is int, not all cases can be covered correctly (nan, inf, -0). With my implementation this works and it follows the std-conventions (sgn(FP) -> FP, sgn(INT/BOOL) -> double). I also tried to optimize them (branch-free, vectorizable). sgn(FP) -> FP ±0/±1 sgn(FP nan/inf) -> FP nan/inf sgn(INT) -> double +0/±1 sgn(UINT/BOOL) -> double +0/+1 regards Gero

C++11 or C++14?
by Vinnie Falco 29 Jul '22

29 Jul '22

I'm considering bumping up the C++ language requirement for Boost.URL from C++11 to C++14. I have concerns about doing this, because it affects all my downstream libraries (HTTP.Proto, HTTP.IO, Websocket.Proto, Websocket.IO, and any examples or complete clients/servers that I write). My main fear is that there are still a considerable number of individuals or corporations who, for whatever reason, cannot build with -std=c++14 or later despite having access to newer compilers. I don't mind if … [View More]

gcc 12 and clang 14
by Matt Hurd 28 Jul '22

28 Jul '22

Curious as to if gcc-12 and clang-14 may make it to the release compiler list for 1.80? (https://www.boost.org/users/history/version_1_80_0.html) Is that just a formality? I see the regression tests for both look in pretty good shape: https://www.boost.org/development/tests/develop/developer/summary.html Thanks all for your great work. Much appreciated, --Matt _______________ matthurd(a)acm.org

boost::asio::ssl::context::use_certificate_chain_file and boost::asio::ssl::context::use_certificate_file Methods Give "bad method" Error
by Osman Zakir 21 Jul '22

21 Jul '22

Hello. Message for update to previously-reported issue. It turns out that the "bad method" error was because of the boost::asio::ssl::context object methods I mentioned in the subject of this email. Reading the certs in from the files into std::strings manually and using use_certificate and use_certificate_chain instead is better, at least from what I saw. I still have an error in the browser (code: ERR_SSL_PROTOCOL_ERROR) when I try to visit my running app saying that the connection … [View More]
