Cannot make rpm from spec file: File not found errors

I have a pre-made directory structure that I want to make an rpm from. In my spec file I specify all files from that directory structure that I want to include in the rpm, and when executing rpmbuild I set the buildroot to the (from what I can tell) correct directory:

%files
/usr/local/bin/test/Test
/usr/local/bin/test/something.awk
/usr/share/snmp/mibs
/etc/init.d/test

My rpmbuild command looks like this:

rpmbuild --rmspec --buildroot=bin/<files dir> -bb bin/tmp.spec

Both the buildroot directory & location of my spec file are relative. The directory structure looks like this:

/home/<me>/Projects/<project>/ <-- I execute rpmbuild from here
/home/<me>/Projects/<project>/bin/tmp.spec
/home/<me>/Projects/<project>/bin/<files dir>/ <-- All files/directories mentioned in spec file reside here
/home/<me>/Projects/<project>/bin/<files dir>/usr/local/bin/test/Test
/home/<me>/Projects/<project>/bin/<files dir>/usr/local/bin/test/something.awk
/home/<me>/Projects/<project>/bin/<files dir>/usr/share/snmp/mibs/ <-- directory with a few MIB files, which I all want to include
/home/<me>/Projects/<project>/bin/<files dir>/etc/init.d/test

However, when executing the rpmbuild command I get the following errors:

Processing files: <rpm>
error: File not found: /bin/<files dir>/usr/local/bin/test/Test
error: File not found: /bin/<files dir>/usr/local/bin/test/something.awk
error: File not found: /bin/<files dir>/usr/share/snmp/mibs
error: File not found: /bin/<files dir>/etc/init.d/test


RPM build errors:
    File not found: /bin/<files dir>/usr/local/bin/test/Test
    File not found: /bin/<files dir>/usr/local/bin/test/something.awk
    File not found: /bin/<files dir>/usr/share/snmp/mibs
    File not found: /bin/<files dir>/etc/init.d/test

The spec file does not contain any %prep, %build or %install directives, as the complete file structure is pre-made before building the rpm file. I am convinced it is some small thing that I am missing, and I suspect that it is a case of rpmbuild using a different directory than I am specifying. I've been toying around with the buildroot & _topdir directives, both with relative & absolute paths, but to no avail...

It seems to me that you are confused by semantics of buildroot. The --buildroot option and %{buildroot} macro points to build root. Let me elaborate more:

In the %install section you are located in directory where your sources have been extracted (this has been done by %setup macro in %prep section). Now you are should create the file/directory structure in the build root. So:

%install
install -d %{buildroot}/usr/local/bin/test/
cp -a something.awk  %{buildroot}/usr/local/bin/test/

This assume that something.awk was in in tar.gz file of Source0 and it was in root of that archive (there was no leading paths in that archive).

%buildroot is always defined. And usually is in form of ~/rpmbuild/BUILDROOT/%{name}-%{version}-%{release}.$arch. When you override it with --buildroot=bin/<files dir> option as in your example, then the previous script in %install will copy the something.awk into 'bin//usr/local/bin/test/something.awk'. Which is not error per se, but does not have sense too.If you previously copied the files into your ./bin directory, then you should know that %{buildroot} is usually wiped before %install section. So you have to copy those files into '%{buildroot}' in this section.

So what was the cause of the error? When you stated:

%files
/usr/local/bin/test/something.awk

Then rpmbuild looks for file %{buildroot}/usr/local/bin/test/something.awk. It does not exist so rpmbuild yield "file not found". So you are obviously missing the actions in %install section. If you add it there then it will work. And you can omit the --buildroot option too.
