error: template argument for template type parameter must be a type template< class Allocator = std::allocator< none > >
by Phil Phil 05 Jul '24

05 Jul '24

Greetings, I try to port a c++ project to a new environment with clang++-17, libcxx 17 and std=c++17 for x64 Linux. Also, I switched form boost 1.65 to 1.84. Now I start getting errors in boost itself: /workspace/usr/include/boost/statechart/fifo_worker.hpp:55:45: error: template argument for template type parameter must be a type 55 | template< class Allocator = std::allocator< none > > As far as I know this has to do with deprecation of some variable type in allocator. Any ideas how I might fix this on short notice? Regards

directory_iterator UNC path
by Lars Sunde 04 Jul '24

04 Jul '24

Hello, Using boost::filesystem::directory_iterator with an UNC path failed with Boost 1.84 and Windows 10. Did some research on this topic and found this bug report from 2022; https://github.com/boostorg/filesystem/issues/245 This issue contain a link to this fix; https://github.com/boostorg/filesystem/commit/9c9d127bddc2b72187c57f4933c49… When looking at boost 1.84 and 1.85 source code I cannot find the fix shown above. Please excuse my ignorance but what is the relationship between https://github.com/boostorg/filesystem and the sw released at https://www.boost.org<https://www.boost.org/> ? Kind regards, Lars [https://opengraph.githubassets.com/d5334b4df3942668241ead9dde0a136ddc1b0979…]<https://github.com/boostorg/filesystem> GitHub - boostorg/filesystem: Boost.org filesystem module<https://github.com/boostorg/filesystem> Boost.org filesystem module.
