Getting Started with RTEMS
RPM is a packaging format which can be used to distribute binary files as
well as to capture the procedure and source code used to produce those
binary files. For RPM, it is assumed that the following subdirectories
are under a root directory such as /usr/src/redhat or
/usr/local/src/redhat) on your machine.
BUILD RPMS SOURCES SPECS SRPMS
For the purposes of this document, the RPM SOURCES directory is the
directory into which all tool source and patches are assumed to reside.
The BUILD directory is where the actual build is performed when
building binaries from a source RPM.
RPM automatically unarchives the source and applies any needed patches
so you do NOT have to manually perform the procedures described
Unarchiving the Tools and Applying RTEMS Project Tool Patches.
But you are responsible for placing all source tarballs
and patches in the SOURCES directory per the instructions in
Obtain Source and Patches
This procedure starts by installing the source (e.g. .src.rpm
extension) RPMs. The RTEMS tool source RPMS are called "nosrc" to
indicate that one or more source files required to produce the RPMs
are not present. The RTEMS source RPMs typically include all required
patches, but do not include the large .tar.gz or .tgz files
for each component such as BINUTILS, GCC, or NEWLIB. These are shared
by all RTEMS RPMs regardless of target CPU and there was no reason to
duplicate them. You will have to get the required source archive files
by hand and place them in the SOURCES directory before attempting
to build. If you forget to do this, RPM is smart -- it will tell you
what is missing. You can fetch any missing files and try again.
