undefined reference to `fmt::v6::internal::is_output_iterator<char*>::value

[Boddlnagg]

In my specific setup (I have integrated fmtlib and its unit tests into a custom build system), I'm getting the following linker error in the unit tests:

fmt/test/format-test.cc:216: undefined reference to `fmt::v6::internal::is_output_iterator<char*>::value'

The compiler is GCC8. On Windows it works.

According to https://stackoverflow.com/a/30277639 using static const bool value = ... is probably not a good idea. But it might also be me doing something wrong ...

Does 2492412 fix the issue?

Should be fixed now but feel free to reopen if you still see the issue. Thanks for reporting!

I can confirm that it is now indeed fixed. Thanks!
