[Buildroot] [PATCH 0/8] package/sdl3*: complete the SDL3 family

[Buildroot] [PATCH 0/8] package/sdl3*: complete the SDL3 family

[Alsey Coleman Miller]

Buildroot has sdl3, sdl3_gfx, sdl3_image and sdl3_ttf. This adds the two
satellite libraries that are missing, fills in options the existing
packages do not offer, and moves SDL3_image off a prerelease.

Patches 1 and 2 add plutovg and plutosvg. plutosvg is a small SVG
renderer built on plutovg, and it is what patch 6 uses: colour emoji
fonts store their glyphs as SVG, which SDL3_ttf renders through the
FreeType OpenType-SVG hooks. Both are useful on their own.

Patch 3 gives sdl3 an ALSA option. There is none today, so whether the
ALSA audio driver is built is decided by what SDL's own detection finds
in the sysroot rather than by the configuration. It also makes D-Bus
follow BR2_PACKAGE_DBUS instead of being off unconditionally - that
costs screensaver inhibition and the D-Bus parts of the Wayland backend
- adds an option for the test programs, and names the audio backends
that were left unset. SDL probes for OSS, JACK, sndio and PipeWire and
builds against whatever it finds, so an unlisted backend makes the
result depend on which unrelated packages happen to be enabled.

Patch 4 moves sdl3_image from 3.1.1, a prerelease, to 3.4.4, and builds
the AVIF, JPEG, TIFF, WEBP and JXL backends according to the image
libraries already in the configuration rather than PNG alone. The option
names changed in 3.4: PNG is SDLIMAGE_PNG_LIBPNG, and
SDLIMAGE_BACKEND_STB selects the built-in decoder used when no helper
library is available.

Patch 5 stops sdl3_ttf building samples that are never installed and
installing man pages that Buildroot deletes again.

Patches 7 and 8 add sdl3_mixer and sdl3_net, the last two SDL3 satellite
libraries without a package. Both are built with CMake, like sdl3
itself, rather than with the autotools setup their SDL2 counterparts
use. sdl3_mixer plays several formats with no dependency at all and
picks up the better decoders - flac, mpg123, opusfile, wavpack,
fluidsynth, libxmp, game-music-emu - when those are already enabled.

check-package is clean over all seven packages. Checked on x86_64/glibc
with alsa-lib, dbus, harfbuzz, jpeg, libpng, tiff and webp enabled, and
again with plutosvg, sdl3_mixer and sdl3_net turned on: the resulting
*_CONF_OPTS and dependency lists are as intended, and BR2_PACKAGE_PLUTOSVG
selects plutovg and turns on SDLTTF_PLUTOSVG. A full build of the series
on that configuration is still running as I send this.

[Buildroot] [PATCH 1/8] package/plutovg: new package

[Alsey Coleman Miller]

plutovg is a standalone 2D vector graphics library providing path
filling and stroking, gradients and text rendering. It is the renderer
plutosvg is built on.

Examples are not built: they are demo programs that are never installed.

[Buildroot] [PATCH 2/8] package/plutosvg: new package

[Alsey Coleman Miller]

plutosvg is a small SVG rendering library built on plutovg.

PLUTOSVG_ENABLE_FREETYPE is on because the FreeType integration is what
provides OpenType-SVG rendering - the hooks FreeType calls for the SVG
glyphs in a colour emoji font - which is what consumers of this library
generally want it for.

[Buildroot] [PATCH 3/8] package/sdl3: add ALSA and test program options, follow dbus

[Alsey Coleman Miller]

SDL_ALSA had no option at all, so whether the ALSA audio driver was
built depended on what SDL's own detection found in the sysroot when it
happened to configure. Add BR2_PACKAGE_SDL3_ALSA and pass
SDL_ALSA_SHARED=OFF with it, so libasound is linked rather than
dlopen()ed - a dlopen leaves nothing in the ELF, and the library is then
absent from the target unless something else pulls it in.

SDL_DBUS was off unconditionally, which loses screensaver inhibition and
the D-Bus parts of the Wayland backend; make it follow BR2_PACKAGE_DBUS.

Add BR2_PACKAGE_SDL3_TESTS for the test programs, which are useful for
checking the video and audio drivers on the target.

Finally, name the backends that were left unset - OSS, JACK, sndio,
PipeWire, RPI - and turn the examples off. SDL probes for each of these
and builds against whatever it finds, so leaving them out makes the
result depend on which unrelated packages are enabled.

[Buildroot] [PATCH 4/8] package/sdl3_image: bump to version 3.4.4

[Alsey Coleman Miller]

3.1.1 is a prerelease. 3.4.4 is the current release, and the option
names changed with it: PNG is now SDLIMAGE_PNG_LIBPNG, with
SDLIMAGE_BACKEND_STB selecting the built-in decoder used when no helper
library is available.

Build the optional format backends according to the image libraries
already in the configuration - AVIF, JPEG, TIFF, WEBP and JXL alongside
the existing PNG - rather than PNG alone. VENDORED stays off so the
copies of those libraries carried in the tarball are not used, and
DEPS_SHARED off so they are linked rather than dlopen()ed.

The formats SDL3_image decodes by itself (BMP, GIF, LBM, PCX, PNM, QOI,
SVG, TGA, XCF, XPM, XV) need no helper and are always available.

[Buildroot] [PATCH 5/8] package/sdl3_ttf: do not build the samples or install man pages

[Alsey Coleman Miller]

SDLTTF_SAMPLES builds example programs that are not installed, and
SDLTTF_INSTALL_MAN puts man pages on the target that Buildroot removes
again. STRICT makes the build fail on a missing dependency rather than
quietly dropping the feature it belongs to.

Also state SDLTTF_HARFBUZZ=OFF in the branch where harfbuzz is absent
instead of relying on the default set above it, so both halves of the
condition read the same way.

[Buildroot] [PATCH 6/8] package/sdl3_ttf: build plutosvg support when available

[Alsey Coleman Miller]

Colour emoji fonts store their glyphs as SVG, which SDL3_ttf renders
through plutosvg. Without it those glyphs are skipped and the rest of
the font still renders.

plutosvg is packaged in the swift-linux ports tree rather than in
Buildroot, so BR2_PACKAGE_PLUTOSVG is undefined on a plain Buildroot and
the branch selects SDLTTF_PLUTOSVG=OFF - the behaviour before this
commit. Not for upstream until plutosvg and plutovg are packaged there.

[Buildroot] [PATCH 7/8] package/sdl3_mixer: new package

[Alsey Coleman Miller]

SDL3_mixer is the multi-channel audio mixer library for SDL3. It plays
AIFF, AU, VOC and WAVE, MIDI through the built-in timidity, and MP3,
Ogg Vorbis and FLAC through the bundled dr_mp3, stb_vorbis and dr_flac
decoders, none of which need a dependency.

The better decoders are built when their libraries are already in the
configuration: flac, mpg123, opusfile, wavpack, fluidsynth, libxmp for
modules and game-music-emu for console chiptunes. Ogg Vorbis comes from
vorbisfile or tremor and never both, since upstream errors out when the
two are enabled together, so tremor is used only when libvorbis is
absent.

VENDORED is off so the copies of those libraries in the tarball are not
used, DEPS_SHARED off so they are linked rather than dlopen()ed, and
STRICT on so a decoder that cannot find its library fails the build
instead of being dropped silently.

Built with CMake, like sdl3 itself, rather than with the autotools setup
the SDL2 counterpart uses.

[Buildroot] [PATCH 8/8] package/sdl3_net: new package

[Alsey Coleman Miller]

SDL3_net is the small cross-platform networking library for SDL3,
providing TCP and UDP sockets and hostname resolution.

Samples are not built and the man pages are not installed: the samples
are demo programs that are never installed, and Buildroot removes
/usr/share/man from the target anyway.

Built with CMake, like sdl3 itself, rather than with the autotools setup
the SDL2 counterpart uses.

Here, the script "utils/check-symbols" reports an error:

package/sdl3_mixer/sdl3_mixer.mk:30: BR2_PACKAGE_GAME_MUSIC_EMU 
referenced but not defined

This symbol does not exist. This package is missing in
your patch series, or this block should be removed.

Could you split this patch in 4 smaller ones?
- one patch for the ALSA change,
- another for DBUS
- another for introducing BR2_PACKAGE_SDL3_TESTS
- finally a last one disabling examples and other unbeeded options

When trying to build this new package with "test-pkg -a -p plutosvg",
the cmake configuration fails for the br-arm-full-nothread toolchain.

See:
https://gitlab.com/jolivain/buildroot/-/pipelines/2872694570

Maybe there is some missing build requirements.

Could you have a look, please?

Thanks for your patch. In the mean time another version bump has been
applied on sdl3_image, but it didn't as much as your patch. So I've
taken the bits of your patch that still made sense, and split them
across multiple commits:

bc8a47c1ef07eabd14789bf11a41eee97d887466 package/sdl3_image: disable vendoring, use direct dynamic linking
1f02444f51c07b9cf7d9d4a644a2709bca8fad7c package/sdl3_image: disable examples, tests, man pages
785365def77065e0338061b9cad5aeee481946e7 package/sdl3_image: be explicit about using libpng
396e388f83af8c54bd27ac59e584fd6daafbc2d4 package/sdl3_image: add optional support for avif, jpeg, tiff, webp, jxl
145d360b9ba62cb918563c034eb1218956db61d5 package/sdl3_image: fail if dependencies are not found

The one thing I didn't pick up are the CPE information. Are there
already CVEs against sdl3_image that allow us to be sure what the
correct CPE identifiers are?

Thanks!

This patch did several unrelated things in the same commit, so I split
it up into several commits:

f9e468d6bb6556933fce7e9ac2dad35ed9fdc42f package/sdl3_ttf: put -DSDLTTF_HARFBUZZ=OFF where it belongs

I'm not sure what happened, but we don't have plutosvg in Buildroot at
the moment, so I changed this to a simpler commit that disables
plutosvg support entirely.

Could you resubmit the plutosvg package and its support, if you're
still interested into this?

Thanks a lot!

Thanks, I've applied your patch. The only thing I've changed is that
I've dropped the CPE identifier information since the commit log did
not provide evidence that these were correct. If you have such
evidence, do not hesitate to submit a follow-up commit.

Thanks for your contribution!
