Python's distutil's copy tree code maintains a cache of directories
created so deleting a tree a different way then coping the same
tree results in an error because the destination folders in the
tree are not present because distutils thinks they exist. The
solution is to implement a copy tree function.
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.
Rework the RTEMS build set files to point to the new location.
Move the files into devel, this follows the ports naming in
FreeBSD.
Update the macros, defaults, and options to support this.
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.
This is an internal command that wraps the Makefile.inc file in
a BSP so you can get at the configuration values from the
command line without knowing anything about Makefile.inc.
To use:
$ ../source-builder/sb-rtems-config \
--rtems=$HOME/development/rtems/4.11 \
--rtems-bsp=sis \
rtems_cpu_cflags
The option '--list' lists all available configuration values.
The configuration values are match case insensitive and you can
list a number with each printed on a separate line.
The --rtems-bsp can be in new coming standard of arch/bsp such as
'sparc/sis' or you can just supply the bsp, eg 'sis'.
Refactor the reporter to allow the setbuilder to use its build config
rather than regenerating the configuration from the configuration file.
Using the config file and the build macros exposed an issue if a
macro was undefined that was defined in a build set above the
config file. Using the build set's configuration as used to build
is a better solution.
The reporter was refactored to allow a config class to be used
to report.
The setbuild can now take a configuration file as an input file.
