create an RPM file

So the a basic step for packaging your (binary) program is as follow – in which i suppose the program is toybinprog with version 1.0, have a conf to be installed in /etc/toybinprog/toybinprog.conf and have a bin to be installed in /usr/bin called tobinprog :

1. create your rpm build env for RPM < 4.6,4.7

mkdir -p ~/rpmbuild/{RPMS,SRPMS,BUILD,SOURCES,SPECS,tmp}

cat <<EOF >~/.rpmmacros
%_topdir   %(echo $HOME)/rpmbuild
%_tmppath  %{_topdir}/tmp
EOF

cd ~/rpmbuild

2. create the tarball of your project

mkdir toybinprog-1.0
mkdir -p toybinprog-1.0/usr/bin
mkdir -p toybinprog-1.0/etc/toybinprog
install -m 755 toybinprog toybinprog-1.0/usr/bin
install -m 644 toybinprog.conf toybinprog-1.0/etc/toybinprog/

tar -zcvf toybinprog-1.0.tar.gz toybinprog-1.0/

3. Copy to the sources dir

cp toybinprog-1.0.tar.gz SOURCES/

cat <<EOF > SPECS/toybinprog.spec
# Don't try fancy stuff like debuginfo, which is useless on binary-only
# packages. Don't strip binary too
# Be sure buildpolicy set to do nothing
%define        __spec_install_post %{nil}
%define          debug_package %{nil}
%define        __os_install_post %{_dbpath}/brp-compress

4. build the source and the binary rpm

rpmbuild -ba SPECS/toybinprog.spec

And that’s all.

 

 

 

Similarly, I needed to create an rpm with just a few files. Since these files were source controlled, and because it seemed silly, I didn’t want to go through taring them up just to have rpm untar them. I came up with the following:

  1. Set up your environment:mkdir -p ~/rpm/{BUILD,RPMS}

    echo '%_topdir %(echo "$HOME")/rpm' > ~/.rpmmacros

  2. Create your spec file, foobar.spec, with the following contents:
    Summary: Foo to the Bar
    Name: foobar
    Version: 0.1
    Release: 1
    Group: Foo/Bar
    License: FooBarPL
    Source: %{expand:%%(pwd)}
    BuildRoot: %{_topdir}/BUILD/%{name}-%{version}-%{release}
    
    %description
    %{summary}
    
    %prep
    rm -rf $RPM_BUILD_ROOT
    mkdir -p $RPM_BUILD_ROOT/usr/bin
    mkdir -p $RPM_BUILD_ROOT/etc
    cd $RPM_BUILD_ROOT
    cp %{SOURCEURL0}/foobar ./usr/bin/
    cp %{SOURCEURL0}/foobar.conf ./etc/
    
    %clean
    rm -r -f "$RPM_BUILD_ROOT"
    
    %files
    %defattr(644,root,root)
    %config(noreplace) %{_sysconfdir}/foobar.conf
    %defattr(755,root,root)
    %{_bindir}/foobar
    
  3. Build your rpm: rpmbuild -bb foobar.spec

There’s a little hackery there specifying the ‘source’ as your current directory, but it seemed far more elegant then the alternative, which was to, in my case, write a separate script to create a tarball, etc, etc.

Note: In my particular situation, my files were arranged in folders according to where they needed to go, like this:

./etc/foobar.conf
./usr/bin/foobar

and so the prep section became:

%prep
rm -rf $RPM_BUILD_ROOT
mkdir -p $RPM_BUILD_ROOT
cd $RPM_BUILD_ROOT
tar -cC %{SOURCEURL0} --exclude 'foobar.spec' -f - ./ | tar xf -

Which is a little cleaner.

Also, I happen to be on a RHEL5.6 with rpm versions 4.4.2.3, so your mileage may vary.
