Building noarch RPMS for SUSE linux.

SUSE has modified the build system from the standard RedHat process.

Here are the steps I took to create a usable RPM package under SUSE.

1.) Install the prerequisite packages on the build server.

# yast -i build

# yast -i gpg

2.) Configure the build environment

The build environment can be modified in numerous ways, but I found the default to be usable.

After issuing the "build" command for the first time as root, a /var/tmp/build-root/ directory structure will be created.

This is basically a skeleton file system. Any files that we want to include in the RPM will go in this directory.

3.) Lay out the files to be included in the RPM.

If you want to install /etc/sudoers, add the sudoers file to /var/tmp/build-root/etc/sudoers ... etc. Then you can note that in the next step.

4.) Create the RPM SPEC file.

Most of the derivatives in this file are self explanatory, but the important ones are noted below.

As a test I created the file /usr/src/packages/SPECS/lukescripts.spec :

--------- Start File

%define name    lukescripts

%define version 1.1

%define release 1

Summary: LukeScripts, a collection of tools

Name: %{name}

Version: %{version}

Release: %{release}

License: GPL

Group: Amusements/Graphics

BuildArch: noarch

Provides: LukeScripts

%description

This package contains LukeScripts, just random scripts as a test for building a non-source RPM.

%prep

exit 0

%build

exit 0

%install

exit 0

%clean

exit 0

%files

/tmp/lukescripts

/cvsrx

---------End File

Note: the BuildArch: tag defines the architecture of the machines that we want the RPM to build on. In this case since we're not building any source code, we specify noarch. Basically, we're just copying text files... If we were building C code, we'd specify i686. 

Note: the %files section of the spec file is what points to the files we want to include in the RPM. Adding /tmp/lukescripts to this section tells RPM to take the files from /var/tmp/build-root/tmp/lukescripts and put them in the binary package. When the RPM is installed, those files will be extracted to /tmp/lukescripts on the target machine. It's chroot juju.

5.) Build the RPM

Once the files are in place and pointed to in the spec file, we can build the RPM.

Change to the directory containing the .spec file... /usr/src/packages/SPECS

Issue the command:

# build

... simple enough. If all goes well the rpm will be created and placed in /var/tmp/build-root/usr/src/packages/RPMS/lukescripts-1.1-1.noarch.rpm

6.) Install and verify the new rpm.

suse1:/var/tmp/build-root/usr/src/packages/RPMS/noarch # rpm -ivh *
