The last installed tool in RTEMS repository is the install-if-change
script. It is not used to build/install BSPs. This script does the
same as the standard "install" program with an additional feature to
install variants via the -V command line option.
This script is used by the standard Makefile support:
c/src/make/host.cfg.in:INSTALL_CHANGE=$(PROJECT_BIN)/install-if-change
The INSTALL_CHANGE is used by:
c/src/make/host.cfg.in:ifndef INSTALL_CHANGE
c/src/make/host.cfg.in:INSTALL_CHANGE=$(PROJECT_BIN)/install-if-change
c/src/make/host.cfg.in:INSTALL_VARIANT=$(INSTALL_CHANGE) -V
"$(LIB_VARIANT)"
Remove the support for variant installation and instead use the standard
"install" program. This breaks application Makefiles using the standard
Makefile support of RTEMS.
Close#3455.
All tools should be removed from the RTEMS source repository at some
point in time. Tools with a BSD-style license will be moved to the
RTEMS tools repository. Unfortunately, this tool has no license
information.
Remove all uses of this tool from the code base. Users of HEX files
should consider to use ELF instead.
Close#3379.
This option silences warning with automake-1.16.1 allowing us to
upgrade to that version.
This change has been tested with automake-1.12.6 and automake-1.16.1.
It seems version 1.16.1 configures slower than 1.12.6 for the same
source and BSP. The newer versions is 6 second slower.
Close#3387.
A speciality of the RTEMS build system was the make preinstall step. It
copied header files from arbitrary locations into the build tree. The
header files were included via the -Bsome/build/tree/path GCC command
line option.
This has at least seven problems:
* The make preinstall step itself needs time and disk space.
* Errors in header files show up in the build tree copy. This makes it
hard for editors to open the right file to fix the error.
* There is no clear relationship between source and build tree header
files. This makes an audit of the build process difficult.
* The visibility of all header files in the build tree makes it
difficult to enforce API barriers. For example it is discouraged to
use BSP-specifics in the cpukit.
* An introduction of a new build system is difficult.
* Include paths specified by the -B option are system headers. This
may suppress warnings.
* The parallel build had sporadic failures on some hosts.
This patch removes the make preinstall step. All installed header
files are moved to dedicated include directories in the source tree.
Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc,
etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g.
erc32, imx, qoriq, etc.
The new cpukit include directories are:
* cpukit/include
* cpukit/score/cpu/@RTEMS_CPU@/include
* cpukit/libnetworking
The new BSP include directories are:
* bsps/include
* bsps/@RTEMS_CPU@/include
* bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include
There are build tree include directories for generated files.
The include directory order favours the most general header file, e.g.
it is not possible to override general header files via the include path
order.
The "bootstrap -p" option was removed. The new "bootstrap -H" option
should be used to regenerate the "headers.am" files.
Update #3254.
This commit deletes all RTEMS ChangeLog files. These files have been abandoned
since converting to git version control. The historical data may be recovered
by checking out any commit before this one. Most of the contents of these
ChangeLog files can also be found in the git log.
Two external ChangeLog files, ChangeLog.slac and ChangeLog.zlib, remain.
These modifications were required by hand after running the script.
In some cases, the file names did not match patterns. In others,
the format of the file did not match any common patterns.
Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.
