In order to automate the complete bootstrap build process we need a
mechanism to control the second phase which builds the final packages
on the booted bootstrap Haiku. To avoid additional dependencies
(buildbot slave, ssh, rsh,...) we'd have to cross-build, there's now a
pair of simple python scripts that allows executing commands on a remote
machine. The server script (bootstrap_daemon.py) is added to the
bootstrap image and started automatically during the boot.
* Drop unused variables from build system that refer to the system
libraries.
* Drop unused lists of libgcc objects.
* Drop no longer used variables from configuration script.
* Remove no longer needed building of kernel-libgcc and -libsupc++ from
build_cross_tools_gcc4, only the boot-specific (32-bit) libs are
built for a x86_64 target.
* Explicitly disable threads and TLS support when building the cross
compiler, as the only libraries that are used by Haiku's build system
is the 32-bit libgcc and libsupc++ for the bootloader on x86_64 (and
for that neither is wanted).
* Building gcc-4.8.3 on x86_64 with TLS support fails with an internal
compiler error. Until that problem is fixed, don't use TLS on x86_64,
which (due to libstdc++ compatibility) requires the same for the
host cross compiler.
Since hrev47198 we have ELF-based TLS support in Haiku. When building
gcc with haikuporter, this is detected by the configure script, but when
cross compiling gcc we need to manually enable it, as no runtime check
can be performed to detect the feature.
This should fix#10938 by avoiding the mix of TLS and non-TLS libstdc++.
Ideally, we would only need to set this in build/jam/board/*, but the
flags set there are not passed to the build of packages. The default is
using some early ARM variant, for which gcc lacks some more atomic
operations and emits calls to helper functions we don't implement.
Setting the default architecture avoids this, as all packages will now
be built to target the Cortex-A8.
Also set the proper VFP version in BeagleBoard config file.
Note this breaks the Verdex and Pi builds, but ARMv7 is what we should
focus on for now. We can try to make older archs work after finishing
the m68k port.
* This avoids mixup of the soft/hard float libs
* It also means we can use the hard-float libs for targets that supports
it
* Again, we could introduce an arm_softfp compiler for targets that
don't have floating point support, with a different gcc build.
* build kernel libgcc and libsupc++ with disabled posix threads for all
architectures. We currently change the configuration manually, as gcc
doesn't easily let us reconfigure without a full rebuild.
* PreprocessPackageInfo rule: Pull out new rule
PreprocessPackageOrRepositoryInfo which does the sed substituation and
optionally the filtering through the C preprocessor.
* HaikuRepository rule: Generate the repository info file (from the
given template). No longer do that in the build_haiku_repository
script.
If for some reason (e.g., a forced rebuild), Buildbot rebuilds the same hrev,
it was possible for the scp command to place the repositoryDir as a subdir
in $arch/$version/, instead of as $arch/version. This should ensure that the
contents of repositoryDir are placed in $arch/$version/.
* Add rule HaikuRepository to build a repository from a repository info
file and a list of package files. It calls a build_haiku_repository
script which does all the work.
* Add target <repository>haiku for building the Haiku package
repository.
It should be built via "jam -q @alpha-raw build <repository>haiku";
the build profile is only needed to activate all build features.
* rule AddPackageFilesToHaikuImage: Add "flags" parameter. The only
supported flag is "nameFromMetaInfo". It causes the packages to be
copied under their canonical file name onto the image.
* Use the new flag for all generated packages save haiku_loader.hpkg.
... before copying the new contents to the image. This caters to the
typical use case of updating an existing Haiku, making manual
intervention to get the new packages activated unnecessary. The downside
is that manually added packages will be removed as well.
* find_directory() and hard-coded paths use /boot/system instead of
/boot/common.
* The build system creates the writable directories in /boot/system
instead of /boot/common.
* The build system no longer installs any packages in /boot/common.
* Remove support for VCSs other than git.
* Make the haiku-revision file a regular build target and make sure it
is built only once.
* Make determine_haiku_revision an actual shell script and simplify
it a bit.
Resolving the package dependencies for system might yield packages that
are already given for common. Filter those out of the list for common
before resolving the common dependencies.
Pass --enable-hybrid-secondary to gcc's configure when building it as
a secondary compiler. Doesn't make a difference for building Haiku
itself, but makes it easier to match the Haiku cross devel package with
the compiler when building bootstrap packages with haikuporter.
gcc 4 only ATM.
The goal is to do hybrid builds in a single jam (instead of calling a
sub-jam to build parts with the secondary tool chain). This changeset
adds support to configure to prepare multiple tool chains.
configure:
* Merge option --build-cross-tools-gcc4 into --build-cross-tools. The
option does now always require a packaging architecture parameter,
i.e. x86_gcc2 for the legacy tool chain.
* Multiple occurrences of the --build-cross-tools and
--cross-tools-prefix options are allowed. The first one specifies the
primary tool chain, the subsequent ones the secondary tool chains.
* All architecture dependent jam variables are now suffixed with the
name of the packaging architecture. The new HAIKU_PACKAGING_ARCHS
contains the packaging architectures for the prepared tool chains. The
first element is for the primary tool chain.
* No longer generate a separate libgccObjects file. Just put the
respective variable into BuildConfig as well.
build_cross_tools[_gcc4]:
* Replace the <haiku output dir> parameter by a <install dir>
parameter. This allows to create different cross-tools directories.
They are simply suffixed by the packaging architecture.
Jamrules:
* For the moment map the variables for the primary tool chain to the
respective suffix-less variables, so that everything still works as
before.
The next step is to actually support the secondary tool chains in the
jam build system. This will require quite a bit more butchering, though.
Also, pre-process all package infos (not only the generic ones) and
define the macro HAIKU_BOOTSTRAP_BUILD, if building a package for a
bootstrap image.
The package kit actually requires the files "repo", "repo.info",
"repo.sha256" to be located under the repository base URL, so the
approach to name the repository file "repo-<hash>" doesn't work.
Now there's a directory "<hash>" which contains the files.
This commit moves the computation of the hash and downloading the
repository file from the build_haiku_image script to the jam build
system. The repo.info is also downloaded and a repository config file
is generated.
* Build libsolv and the dependency solver part of the package kit for
the build platform.
* Add build tool get_package_dependencies. Given a list of package files
and a list of repository files it determines the additional packages
that need to be retrieved from the repositories and prints their URLs.
* Add rules to work with external repositories in the build system
(build/jam/RepositoryRules):
- PackageRepository declares an external repository with all its
packages. The URL of the repository file isn't specified. It is
computed from a given base URL and the SHA256 hash of the list of
package files.
- GeneratedRepositoryPackageList generates a file containing the file
names of all packages in a repository.
- IsPackageAvailable returns whether a package is available in any
repository.
- PackageURL returns the URL for a package.
* Declare the HaikuPorts repository for x86_gcc2
(build/jam/repositories/HaikuPorts/x86_gcc2).
* Add rule AddHaikuImagePackages to add a package to the image and rule
IsHaikuImagePackageAdded to determine whether a package has been
added.
* OptionalPackages: Remove all entries that just downloaded and
installed an external package. AddHaikuImagePackages can be used
instead and is used in the remaining entries. Also move the remaining
optional package dependency declarations from
OptionalPackageDependencies here.
* ExtractBuildFeatureArchives: Instead of the URL parameter a package
name must be specified now. This allows to simplify BuildFeatures
significantly, since there's no dealing with URLs anymore. "if" out
the entries that aren't supported yet.
* build_haiku_image: For the packages installed in system and common
resolve their dependencies and download and install them as well.
* at least for gcc2, we used to leave the 'os' subfolder in there,
which may have caused problems when Haiku's headers have changed
since the last time the compiler was built.
(cherry picked from commit 92bb2fb33e)
* force creation of a cross-compiler for both gcc2 and gcc4 when
building on Haiku (by suffixing the build and host machine with
'_buildhost')
(cherry picked from commit df69e209bb)

* at least for gcc2, we used to leave the 'os' subfolder in there,
which may have caused problems when Haiku's headers have changed
since the last time the compiler was built.
* add HAIKU_PACKAGING_ARCH, which is set to the target packaging
architecture
* introduce support for generic package infos, which are package infos
that are the same for all architectures, except for the declaration
of the package architecture itself
* move package info files underneath architecture-specific or generic
folder
