I'm learning how to make rpm's for fedora but I get following error (fg: no job control)

If you look at the generated rpm-tmp shell script it may
become clearer what is going wrong...

I think you should avoid unnecessary indentation in your
spec file.  Try instead:

--
%prep
#unpack source code  -q: quiet
%setup -b
#apply patch on source code
#%patch0 -p1 -b .


#all commands needed for building
%build
#configure properly packages that use autoconf and automake
%configure
make
--
