I've often had linker errors when re-building gamescope if I'm not building from scratch Try doing: (I'm adding an optional --buildtype=debugoptimized because otherwise compiler optimizations are off by default)

meson setup build --reconfigure --wipe --buildtype=debugoptimized
git submodule update
ninja -C build

I tried what you said, but unfortunately it didn't help. I see the same error with destructor not found.

Yeah! I found the problem. My repository was missing the libeis-devel package. It’s strange that the meson didn’t tell me this during configuration. I found two interesting lines in the src/meson.build:

...
eis_dep = dependency('libeis-1.0', required : get_option('input_emulation'))
...
gamescope_cpp_args += '-DHAVE_LIBEIS=@0@'.format(eis_dep.found().to_int())
...

At the same time, the entire file src/InputEmulation.cpp is surrounded by #if HAVE_LIBEIS. And this file contains the definition of the destructor, and all the methods for the GamescopeInputServer class.

Correction suggestion: Fix src/meson.build so that a configuration error is thrown if there is no dependency "libeis"
