Hello everyone - I have upgraded one of my test machines to Fedora 41. Therion 6.2.0 now fails to run with a complaint that libfmt.so.10 cannot be found. Very true! The fmt package was upgraded to version 11 and the shared library is now libfmt.so.11. I downloaded the latest source code for version 6.2.1 and went to compile it. The compile fails, and I think it is related to fmt. The last few lines from the compile run are listed below. How can I get past this? Thanks! -- =============== Bill Gee [ 57%] Building CXX object CMakeFiles/therion-common.dir/therion.cxx.o In file included from /usr/include/fmt/format.h:41, from /usr/include/fmt/core.h:5, from /home/bgee/Installs/therion-6.2.1/thepsparse.cxx:42: /usr/include/fmt/base.h: In instantiation of ‘static void fmt::v11::detail::value<Context>::format_custom_arg(void*, typename Context::parse_context_type&, Context&) [with T = thdouble; Formatter = fmt::v11::formatter<thdouble>; Context = fmt::v11::context; typename Context::parse_context_type = fmt::v11::basic_format_parse_context<char>]’: /usr/include/fmt/base.h:1383:19: required from ‘fmt::v11::detail::value<Context>::value(T&) [with T = thdouble; Context = fmt::v11::context]’ 1383 | custom.format = format_custom_arg< | ~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~ 1384 | value_type, typename Context::template formatter_type<value_type>>; | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/fmt/base.h:1647:41: required from ‘constexpr fmt::v11::detail::value<Context> fmt::v11::detail::make_arg(T&) [with bool PACKED = true; Context = fmt::v11::context; T = thdouble; typename std::enable_if<PACKED, int>::type <anonymous> = 0]’ 1647 | return {arg_mapper<Context>().map(val)}; | ^ /usr/include/fmt/base.h:2018:74: required from ‘constexpr fmt::v11::detail::format_arg_store<Context, NUM_ARGS, 0, DESC> fmt::v11::make_format_args(T& ...)
