Using spdlog with fmtlib 536cabd562831816450ce3f9e57d4da0777ffa9b gives me compile errors

[Vertexwahn]

I try to use fmtlib with commit hash 536cabd562831816450ce3f9e57d4da0777ffa9b (from Nov 15, 2024) when building spdlog (with commit hash 51a0deca2c825f1d4461655a18bb37d6df76646d from Nov 9, 2024) (I set the define SPDLOG_FMT_EXTERNAL)

I get the following compile error:

In file included from external/spdlog~/include/spdlog/spdlog.h:12,
                 from ./core/logging.hpp:44,
                 from core/platform.cpp:37:
external/spdlog~/include/spdlog/common.h:369:54: error: 'template<class T, class ... Args> fmt::v11::basic_string_view<Char> spdlog::details::to_string_view' redeclared as different kind of entity
  369 | inline fmt::basic_string_view<T> to_string_view(fmt::basic_format_string<T, Args...> fmt) {

If I use fmt version 11.0.2 everything compiles without errors.

Unreleased fmt is not supported yet. If the same error occurs after release, it will be fixed.

Close this for now.

I recently encountered a bug caused by macro conflict from fmt with cpprest. It has been fixed by this commit in fmt. Since without new release from fmt and unreleased fmt is not supported, is there any way to fix that ?

You can try to use the fixed fmt with “cmake -DSPDLOG_EXTERNAL=ON” when building spdlog

Sadly it's not working. Avoiding use U macro in cpprestsdk by add_definitions(-D_TURN_OFF_PLATFORM_STRING) in CMakeLists.txt is a workaround for me. Thanks for your help.
