I am writing a .spec file to build my own .rpm.
Here it is, non completed:

mkdir -p src/github.com/mattermost

cd %{_builddir}/src/github.com/mattermost/platform

%install

%changelog

---------------------------------------------

Before going further, I want to test, so run:

$ fedpkg --dist f24 local

Everything went fine and was left with the wanted binaries, BUT I have this error at the very end:

------------------------------------------

My %files section is indeed empty as I did not finished writing the .spec file.
Shall I overcome for now this error  and consider my local build test as successful ?
