The config.guess file needs to know about the SerenityOS `uname -m`
system name if we want to build ports inside Serenity. Support was only
added in January 2022, so most ports don't have a new enough version
yet.
This commit adds facilities for fetching a fresh config.guess file that
supports SerenityOS, similarly to what we do for config.sub. As its
first user, we make the bash port buildable inside the system.
We don't have a perl port, so let's use GNU sed's in-place option for
doing substitutions when running inside Serenity.
Note that we can't do this unconditionally, as `sed -i` is not portable
and works differently on BSD systems.
We now download a versioned tarball instead of the latest release to
avoid breaking the port build due to a signature mismatch when a new
version is released.
This depends on both the `libmpeg2` and `libmad` ports. Since `monkey4`
is currently an experimental engine in ScummVM, we need to explicitly
enable it during configuration.
Relying on host tools working correctly is not a good idea, as they may
be outdated (and therefore not support features like RELR relocations)
or may not exist at all (like objcopy on macOS).
While troubleshooting why gdb wasn't working when attempting to debug
serenity programs I noticed two things:
- The contract of serenity's `waitpid(..)` appears to be slightly
different than the generic ptrace target expects. We need to make
sure we pass `WSTOPPED`, and it can return different errno values
that we would want to re-try on.
- The contract of serenity's `ptrace(..)` implementation appears to
diverge as well, as we are expected to call `PT_ATTACH` before we
call `PT_CONTINUE`, otherwise `ptrace(..)` will just error out.
These two patches fix the behavior of wait and mourn_inferior so that
they work as expected on serenity and allow us to attach and then wait
for a process to exit while running under gdb.
This also switches to checking out a specific commit instead of just the
master HEAD, as the port linter requires a hash (which is imo pointless
in this case), and we can't provide a stable hash for the master branch
HEAD.
When I did a fresh build of ports, I got this while building fontconfig:
```
checking for FREETYPE... no
configure: error: Package requirements (freetype2 >= 21.0.15) were not
met:
No package 'freetype2' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables FREETYPE_CFLAGS
and FREETYPE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
```
When a git patch that doesn't apply is encountered, start a git am
session and _then_ drop the user in it instead of expeting the user to
start the session on their own.
Also prompt for leftover files and delete them if the user does not want
them.
This hash format offers faster symbol lookup than the System V hash.
We've been using it in all our shared libraries for a long time, but did
not have it enabled by default in our toolchain, so ports couldn't make
use of it.
Before this change, our dynamic linker's global constructor handler
relied on the GNU linker implicitly including the content of `.ctors`
section inside `.init_array`. The mold linker does not do this, so
global constructors would fail to be called in the mold-built userland.
There is no point in sticking to `.ctors`, as most other systems already
use the superior `.init_array` scheme. This commit changes the kernel
linker script to not discard this new section, and enables it by default
in our toolchain.
The new `use_fresh_config_sub` option puts the config.sub in the root of
the tree, but `readline` puts it in the `support/` folder. So we need to
tell the ports infrastructure to place the file in that folder.
All of these patches did the same thing, which is already in upstream
config.sub.
With this change, we need only add `use_fresh_config_sub=true` to
the package.sh file.
Note that this is not done automatically in case the port has a modified
config.sub file.
According to the OpenGL spec, invoking functions without an active
context results in undefined behavior. Since ScummVM seems to be the
only port having issues with our behavior, patch their code instead.
The port exposes some dynamic loader and toolchain shortcomings,
namely RTLD_NEXT, RTLD_NOLOAD, and std::filesystem. Hopefully we can
discover a ton of multi-threading bugs in Serenity with this port :^)
This commit backports the LLVM commit that adds support for the
`--update-section` flag to llvm-objcopy. We use this feature of GNU
objcopy to embed the symbol map in the kernel.
The corresponding LLVM Phabricator Differential Revision can be found
here: https://reviews.llvm.org/D112116
This patch is identical to the upstream commit, except for two hunks
that had to be changed as they didn't apply cleanly.
This removes the shlib hack from the install step, which repackaged the
static library as the shared one. It also has the benefit of making the
port work with the Clang toolchain :^).
Running `./package.sh interactive` in a port directory will
spawn a new shell with the serenity build environment set up.
This makes porting software much easier as build commands can
be run interactively instead of having to modify package.sh
just to test things.
The --enable-optimizations flag attempts to enable PGO. Profile-guided
optimization is great in general, but will not work at all when doing a
cross-compile. If there's a more fine-grained flag for generic
optimization levels that doesn't try to do PGO, we should enable that
instead. The flag also enables `-fno-semantic-interposition`, but our
GCC patches enable that by default for -fPIC anyway, so that's not
necessary.
Ports such as python require a distinction between host readelf and
target readelf. Set a toolchain-specific varaible for these, but be sure
save off the host readelf binary in case anyone needs it later.
This is part of allowing python to build with the Clang toolchain.
This allows building with the clang toolchain. We might consider a more
global patch in the future for this, it seems a lot of packages need
help to find /usr/local/lib.
By telling the libtool-related configure checks that the serenity
platform does in fact support shared libs, we can get a VERSYM-free
shared lib out of sqlite. This probably applies to other ports as well.

This uses sha256 instead of signatures like what has been done for the
other ports.
This version of libtiff uses the version of config.sub which has
Serenity in it, so this port no longer needs any patches! :^)
The configure script for `SDL2_mixer` was trying to find the shared
library for `libmodplug` in the wrong directories and with the wrong
filename. This installs the shared library as `libmodplug.so.1` and
symlinks to it from `libmodplug.so`, and instructs the `SDL2_mixer`
build to search for it in `/usr/local/lib`.
Fixes the build for ports Super-Mario, freeciv and dungeonrush.
This file apparently relies on the fact that `sys/wait.h` _may_ include
symbols from `signal.h`, but as we don't have that (and it isn't a
requirement), let's just add the include for `signal.h`.
These environment variables would linger after the `php` port was done
building. This would pose issues in the future if other ports depend on
this package, since these vars then leak into the build scripts.
The README previously described `depends` as a space-separated
string. This is now changed to an array, which seem to be the
correct type used in the other Ports.
