Boost Graph + Compute Libraries
by Muhammad Hassan Khan 20 Apr '21

20 Apr '21

Hi, I am new to boost libraries. I was wondering if I can use boost graph and boost compute libraries in one code to implement graphs on GPUs. Can you give any example if it is possible? or any other solution to it. Thank you. Regards, Hassan Khan

ASIO: acceptor::async_accept throws "Operation cancelled" after restart io_service
by Joost Kraaijeveld 19 Apr '21

19 Apr '21

Hi, In short my program: - creates an io_service - calls acceptor::async_accept - calls io_service.run - handle several connections OK - calls io_service.stop - the acceptor goes out of scope (i.e. the destructor of the owning object is ran) - calls io_service.restart - calls acceptor::async_accept which then throws "Operation cancelled" Should it be possible to do this? When/under what circumstances does async_accept throw this exception? Could it be connected with the fact that the acceptor's destructors documents that is does some cleanup but actually does nothing, from the source: /// Destroys the acceptor. /** * This function destroys the acceptor, cancelling any outstanding * asynchronous operations associated with the acceptor as if by calling * @c cancel. */ ~basic_socket_acceptor() { } OS: Linux Debian Bullseye, Boost 1.74, gcc 10 TIA Joost

Boost.Test - test tree is empty
by Olaf Peter 17 Apr '21

Hello, I am in despair. The attached source compiles fine, but gives: $ bin/utf_dataset_loader_issue Test setup error: test tree is empty and I don't know why. It is based [Data-driven test cases parametrized from the command line <https://www.boost.org/doc/libs/1_73_0/libs/test/doc/html/boost_test/runtime…>](https://www.boost.org/doc/libs/1_73_0/libs/test/doc/html/boost_test/runtime_config/custom_command_line_arguments.html#boost_test.runtime_config.custom_command_line_arguments.data_driven_test_cases_parametri) but reduced to pure API, no cli parse, file loading etc. Any help is appreciated.

Information about a Fixed Point type
by Emilio Paolini 13 Apr '21

13 Apr '21

Hi everyone, i'm new to Boost. I would like to know if there is a way, using this library, to declare a fixed point type, specifying the number of bits for the fractional part and the behaviour when overflow happens. Thank you very much. Regards, Emilio

A new home for Boost releases
by Marshall Clow 12 Apr '21

12 Apr '21

We’ve been using BinTray to host our releases for a few years, and it’s worked well for us However, JFrog is shutting down BinTray soon (at the end of this month). We have moved all the releases that were hosted on BinTray over to JFrog Artifactory. They are at https://boostorg.jfrog.io/artifactory/main/release <https://boostorg.jfrog.io/artifactory/main/release> For example, instead of: https://dl.bintray.com/boostorg/release/1.74.0/source/boost_1_74_0.tar.gz <https://dl.bintray.com/boostorg/release/1.74.0/source/boost_1_74_0.tar.gz> You should now use: https://boostorg.jfrog.io/artifactory/main/release/1.74.0/source/boost_1_74… <https://boostorg.jfrog.io/artifactory/main/release/1.74.0/source/boost_1_74…> I’ll be updating the web site soon, but if you have automation that relies on BinTray, you should update it to use the new home. — Marshall P.S. The “nightly” snapshots will live there too, as soon as we get that set up.
