* From now on, the gcc-specific system libraries (libgcc, libsupc++ and
libstdc++) are provided by separate packages built along with gcc:
- gcc_syslibs contains the shared libraries (libgcc_s.so, libsupc++.so and
libstdc++.so)
- gcc_syslibs_devel contains the static libraries and both c++ and gcc
headers
The shared libraries now make proper use of symbol versioning and there
are version-specific symlinks
* The buildsystem has been adjusted to no longer use the libraries and
headers from the cross-compiler, but use the ones provided by the
above-mentioned packages. The only exception is that the 32-bit libraries
required for the bootloader of the x86_64 architecture are still taken
from the cross-compiler.
* 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).
* If --no-downloads has been given, Haiku will be built without
trying to download anything, all required packages need to be put
into the download folder manually (the build will stop on missing
packages).
* As the required HaikuPorts repository can't be downloaded in this
mode, a local repository is created during the build, which only
contains the packages available in the downloads folder.
This is useful for building Haiku completely from source.
* Since this affects generated objects and needs a clean build anyway,
it is better set and fixed at configure time.
* It could also be used when building the cross compiler to set
appropriate options.
* As per the ML discussions. Bumps MIPS to tier 3.
* We've reached a unanimous descision that MIPS doesn't
target any real / valid hardware Haiku wants to pursue
at the moment. In the event that anyone wants to pursue
MIPS, feel free to fork Haiku into your own repository
(and we'll even link to it on the website ports page)
* If someone develops a viable plan for MIPS (and gets the
port working, it can be readded at a later date)
* as Ingo has pointed out, the remote user settings doesn't
relate to the build configuration at all, so setting the
remote user via HAIKU_REMOTE_USER in UserBuildConfig or
via shell environment is the way to go
* additionally: drop debug output
* add option --remote-user to configure, which sets HAIKU_REMOTE_USER
* add evaluation of HAIKU_REMOTE_USER variable when ssh-ing
into git.haiku-os.org
This allows FreeBSD with a pure /bin/sh (not a symlink to /bin/bash) to build
the cross-tools to a dedicated directory, outside of the generated folder.
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.
* Add configure option --bootstrap which allows specifying the
haikuporter and HaikuPorts repository paths.
* Add rules for supporting a second repository type. The
PackageRepository rule is now private and RemotePackageRepository is
used for remote repositories. The new BootstrapPackageRepository rule
is for defining a bootstrap repository (there will probably be only
the HaikuPorts cross repository) whose packages can be built as needed
via haikuporter.
* Rename DownloadPackage to FetchPackage.
* Define repository HaikuPortsCross.
* HaikuCrossDevel package(s): There are now two sets of packages: A
"stage1" set with the same content as before and a final set
additionally containing the libraries libbe, libnetwork, libpackage.
Those are needed for building the libsolv bootstrap package while for
building them we need other bootstrap packages (ICU, libz).
This is basically all that's required to build a bootstrap Haiku
completely from sources, with a few caveats:
* There's no ICU bootstrap recipe yet (so one has to cheat and use the
prebuilt package ATM).
* Probably doesn't work on Haiku yet (tested on Linux only).
* A 32 bit environment must be used (otherwise building the gcc 2
bootstrap package fails).
* Building with multiple jobs doesn't work yet, since haikuporter uses
common directories for building different packages and there's no
explicit serialization yet.
* Haven't tested the resulting image save for booting it. So it probably
needs a bit more work before it can actually build the final
HaikuPorts packages.
The new configure option "--use-xattr-ref" enables an xattr assisted
variant of the generic attribute emulation. Instead of using the inode
ID of a node to identify its attribute directory, we use a reasonably
unique random 128 bit number, which we generate and attach as an
attribute to the node. This way, when a node changes its inode ID
(defragmentation?) or the inode ID of a removed node with a left-over
attribute directory is reused, attributes won't get mixed up.
The old method is still used for symlinks (since on Linux only
priviledged users can write attributes on symlinks), but those usually
only have a rather boring BEOS:TYPE attribute, so mix-ups wouldn't be
that problematic anyway.
