Possible context of error(s): /var/tmp/portage/dev-libs/spdlog-1.8.5/work/spdlog-1.8.5/include/spdlog/common-inl.h:63:50: error: cannot convert ‘const string’ {aka ‘const std::__cxx11::basic_string<char>’} to ‘const char*’
Same error here, if dev-libs/libfmt-8.0.0 is installed. With dev-libs/libfmt-7.1.3 it builds successful.

Created attachment 717540 [details, diff] Fix spdlog compile with libfmt 8.0 It appears to be this bug: https://github.com/gabime/spdlog/issues/1941 There's a patch, but it's listed under this Visual Studio specific bug for some reason: https://github.com/gabime/spdlog/issues/1955#issuecomment-860676872 There doesn't seem to be a PR to include it upstream yet though. Patch is attached, it fixes the build with libfmt 8 for me.
(In reply to Tiernan Hubble from comment #5) [...] Yes, the patch works for me too Thanks!

How would I go about applying that patch to the ebuild on my local host?
