Utility: FileWatcher does not compile on gcc 5.4.0 about corrade

Hi, thanks for the report (and thanks for going an extra way with the bisect)! 👍

I did a similar workaround for Clang 3.8 in d26b546 and assumed that this, having it worked on the venerable GCC 4.7, would work on all newer GCCs as well (it does work on 8 again)...

I'll look around if I have some GCC 5 around to test on, in the meanwhile can you try removing the noexcept specifier from the operator=? That should make it work.

Works without the noexcept 👍

Just tested locally with GCC 5.5 and there it works. Turns out to be a bug/non-conformance in libstdc++ < 5.5: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58265 Now I'm not sure why it worked on 4.7 (probably the compiler just didn't care back then).

I pushed a fix in c32b096 (it's the next branch at the moment, not master yet). Could you verify it works, please? Thank you!

next compiles just fine for me.

Thanks for the confirmation! Merged into master now.

That was quick, thanks! :-)
