This changes adds support to build the autotools if the host installed
version is not a suitable version. Autoconf and automake have hard coded
references to the install prefix and host tools and this makes it impossible
to relocate, that is use in any path other than the install prefix. To
bootstrap automake you need to first build a suitable autoconf and with that
you can built automake for the install prefix. The other complication is
not referencing the install prefix in the path when building in the RSB.
Having the install prefix in the path can result in strange issues appearing
such as gcc using a new assembler feature not present in an older assember
installed under the install prefix.
The process is to build the autotools using an install prefix to an
internal path inside the RSB temporary path and to use that autoconf
to build the version for the install prefix. The internal install
prefix version is also used to bootstrap RTEMS.
Set up the rules to manage the separate host and build setting to
allow a Canadian cross to complete.
Update the scripts to move the build directory and host/build
flags into the defaults so they are common for all build
configurations.
Fix paths that need to be coverted to host format.
The shell expansion needs to invoke a shell on Windows as cmd.exe
will not work.
Munch the paths into smaller sizes for Windows due to the limited
path size.
Add support to use a git cloned repo as the source. Move the download
code out of the build module and into a separate module. Add to this
module support for git.
Update the GCC common configuration to support using a symlinked
git repo.
Add checks for all languages.
User macro files passed on the command line allow a user to
override the defaults in configuration files to test new changes
in pending releases.
Fix macros issues with keys with more than one map.
To support building snapshots and pre-release source the defaults
has been refactored. The defaults have been moved to a stand alone
file and a macros.py module added. This modile abstracts the
old default dictionary turning it into a class. The macros
class can load macros from a file therefore the defaults have
been moved to a stand alone file.
The use of defaults has been removed from the project. The only
case where it is used in the options where the defaults are read
from a file. Macros are used everywhere now.
The defaults.py has been moved to the option.py and the separate
options and defaults values has been moved to a new pattern. When
constructing an object that needs macros and options if the macros
passed in is None the defaults from the options are used. This makes
it clear when the defaults are being used or when a modified set of
macros is being used.
The macros class support maps. The default is 'global' and where all
the defaults reside and where configuratiion file changes end up.
Maps allow macros to be read from a file and override the values
being maintained in the 'global' map. Reading a macro first checks
the map and if not present checks the 'global' map.
The addition of maps to the macros provides the base to support
snapshots and pre-release testing with standard configurations.
This functionality needs to be added. It works by letting to
specify a snapshot with:
source0: none, override, 'my-dist.tar.bz2'
and it will be used rather the value from the standard configuration.
With a build set you need to also specify the package these macros
are for. The maps provide this.
Refactor the options handling in defaults.py to allow the --jobs
option have varing specific parameters. The option supports 'none',
'max' and 'half' or a fraction to divide the number of CPUs or
an integer value which is the number of jobs. The --no-smp has
been removed.
The host specific modules have been changed to set the number of
CPUs in the defaults table.
Fixed the --keep-going to clean up is --always-clean is provided
even if the build has an error.
Add support to build MinGW tools using Cygwin. This is a Canadian cross
build.
Do not expand the directives when parsing a configuration file. Hold
in the package object the text as read from the configuration file. Still
parse the logic but leave the macros. This allows a configuration to be
varied when the build happens. The Canadian cross uses this to build a
build compiler used to build a Cxc runtime.
Add Cxc support to the build module. In the defaults add rm and rmfile
macros, add Cxc paths and pre-build script code.
In the setbuilder check for a Cxc build and if so and the package
allow Cxc build the build host version then the host target
version.
Add cygiwn support to the defaults processing and to the Windows module.
By default the Source Builder now directly installs in the prefix and
does not create tar files. You need to supply options to create build
set level tar files and/or package level tar files.
Remove the need to add the --force option. Also revert the force option
back to the --force from --no-force and leave it so the user can
bypass the host check of various packages.
A build set can invoke another build set. This allows an 'all'
type build set that builds all the RTEMS archs.
Change the get config call to return a map of paths and files.
