rpmbuild install dependency

I'm new to rpmbuild + spec files and I tried the following tutorial to build the "hello world" example.

Manage to get it working, but I wanted to learn how dependencies/requires works. Therefore, I tried to duplicate another "hello world 2" example and link it as a dependency to the first in the spec file below.

However I keep getting the error below. Is there a way that yum install will pick up the helloworld1 and install automatically when i yum install helloworld2 ?

Any example for me learn from?

SPEC FILE

Name:           helloworld2

Source0:        helloworld2-2.0.tar.gz

#BuildRequires: helloworld1
Requires(preun):  helloworld1
#PreReq: testYW

%install

echo %{?buildroot}

%clean
rm -rf %{buildroot}

%files
%{_bindir}/helloworld2

 You could try using --skip-broken to work around the problem

okay ! i got the answer !

i can either do a yum install *.rpm , which it will do its own dependency

else putting all the new rpm file into the repository and it will pick it up :)

since helloworld2 requires helloworld1; you should either install helloworld1 first; either install both together. Since helloworld2 depends on helloworld1; you cannot install him without installing helloworld1 first (or at the same time).
