RPM support for BSPs
|
||||
====================
|
||||
|
||||
Introduction
|
||||
------------
|
||||
|
||||
Building an rpm requires to have a tar archive of the sources, and a
|
||||
rpm-spec files specifying the details of building.
|
||||
|
||||
To support per bsp rpms, one rpm-spec is used per BSP.
|
||||
Instead of writing one rpm-spec for each BSP, I have written a shell script
|
||||
(mkspec) which generates one *.spec (rtems-<target_alias>-<bsp>.spec) per BSP
|
||||
bsp from an rpm-spec template (rtems.spec.in).
|
||||
|
||||
A second shell script (mkrpms) is a convienience script which invokes a
|
||||
sequence of building rpms for several bsps.
|
||||
|
||||
mkspec
|
||||
------
|
||||
|
||||
mkspec takes two arguments:
|
||||
$1 ... the bsp to be built
|
||||
$2 ... the target_alias this bsp belongs to
|
||||
|
||||
Invoking mkspecs will generate a rtems-<target_alias>-<bsp>.spec either in
|
||||
/usr/src/packages/SPECS (SuSE convention) or
|
||||
/usr/src/redhat/SPECS (Redhat convention) or
|
||||
/usr/src/SPECS
|
||||
|
||||
Eg. ./mkspec gensh1 sh-rtemself generates
|
||||
/usr/src/packages/SPECS/rtems-sh-rtemself-gensh1.spec on SuSE-6.2.
|
||||
|
||||
Building BSP-rpms
|
||||
-----------------
|
||||
|
||||
0. Login as root.
|
||||
|
||||
1. Install a tarball of RTEMS's sources (with version number attached!) to
|
||||
/usr/src/[packages|redhat]/SOURCES
|
||||
Eg.
|
||||
tar czvf /usr/src/packages/SOURCES/rtems-<VERSION>.tar.gz rtems-<VERSION>
|
||||
|
||||
2. Generate and install the required rpm-spec file[s]
|
||||
cd rtems-<VERSION>/scripts/
|
||||
mkspec <bsp> <target_alias>
|
||||
|
||||
3. Build the rpms
|
||||
Building a binary rpm:
|
||||
rpm -bb /usr/src/[packages|redhat]/SPECS/rtems-<target_alias>-<bsp>.spec
|
||||
|
||||
Building a source and binary rpm
|
||||
rpm -ba /usr/src/[packages|redhat]/SPECS/rtems-<target_alias>-<bsp>.spec
|
||||
|
||||
Note: a BSP's src.rpm contains its spec-file and the tar-archive of the
|
||||
sources (approx. 4-5MB per BSP).
|
||||
|
||||
Known Bugs/Deficiencies
|
||||
-----------------------
|
||||
|
||||
* All files mentioned in here are in its early infancy ;-)
|
||||
|
||||
* Building for a single bsp requires an own copy of the source tree inside
|
||||
rpm's build directory.
|
||||
* Building inside the RTEMS source tree doesn't work.
|
||||
* Dependencies on toolchain-rpms not yet supported in rtems.spec.in.
|
||||
* Installing multiple binary bsp rpms for the same target can cause
|
||||
warnings from rpm, because these bsp-rpms share files.
|
||||
* rtems.spec.in is prepared for rpm relocation support, but RTEMS is not
|
||||
relocatible (yet?)
|
||||
* rtems.spec.in deserves to be extended (description, authors etc)
|
||||
* The final packaging stage to build a binary rpm takes an awful lot of
|
||||
time - deserves to be investigated.
|
||||
* Some RTEMS's cross executables (eg. hello.exe for sparc-rtems/erc32) cause
|
||||
warnings from rpm and/or objdump. AFAIS, this is a bug in rpm.
|
||||
* Probably many more ...
|
||||
|
||||
* Last but not least: RTEMS should be split.
|
||||
|
||||
Remarks
|
||||
-------
|
||||
* It would make sense to split RTEMS host/cross-tools and files depending on
|
||||
the target only (<target_alias>/make/*.cfg -- Whow, RTEMS really has files
|
||||
which depend on the target only :) into separate rpms.
|
||||
* Instead of using a single rpm-spec for each bsp, RTEMS could also use a
|
||||
single rpm-spec for all (or at least a given subset of all) bsps of a target.
|
||||
* rpm -b[b|a] leaves its built trees unpacked in
|
||||
/usr/src/[packages|redhat]/BUILD. Therefore you will rather soon run out of disc
|
||||
space if not removing them. (Use rpm --clean -b[a|b] for cleaning them up
|
||||
automatically after building)
|
||||
* The size of binary rpms can differ up to one magnitude depending on the
|
||||
target/bsp (eg. sh-rtems/gensh1 ~10MB vs. sh-rtemself/gensh1 ~32MB)
