History
|
|
-------
|
|
|
|
The RTEMS Source Builder is a stand alone tool based on another tool called the
|
|
*SpecBuilder* written by Chris Johns. The *SpecBuilder* was written around 2010
|
|
for the RTEMS project to provide Chris with a way to build tools on hosts that
|
|
did not support RPMs. At the time the RTEMS tools maintainer only supported
|
|
*spec* files and these files held all the vital configuration data needed to
|
|
create suitable tool sets. The available SRPM and *spec* files by themselves
|
|
where of little use because a suitable ``rpm`` tool was needed to use them. At
|
|
the time the available versions of ``rpm`` for a number of non-RPM hosts were
|
|
broken and randomly maintained. The solution Chris settled on was to use the
|
|
*spec* files and to write a Python based tool that parsed the *spec* file
|
|
format creating a shell script that could be run to build the package. The
|
|
approach proved successful and Chris was able to track the RPM version of the
|
|
RTEMS tools on a non-RPM host for a number of years.
|
|
|
|
The *SpecBuilder* tool did not build tools or packages unrelated to the RTEMS
|
|
Project where no suitable *spec* file was available so another tool was
|
|
needed. Rather than start again Chris decided to take the parsing code for the
|
|
*spec* file format and build a new tool called the RTEMS Source Builder.
