Knowledge-Technology(Claude Opus 5) used - to analyse and reassess the situation - to discuss and weigh the findings and develop solutions - to perform the selected mitigation and verify success ---- = Report by Claude = A sweep with Clang-22 over all 597 translation units (driven from the newly generated compilation database) showed 271 of them failing, yet with the 2502 diagnostics tracing back to very few root sites. This resolves those where GCC is simply the more permissive of the two; the remaining clusters are a matter of design and are left alone for now. * `using Alias::OriginalName;` does *not* declare inherited constructors. Per [namespace.udecl] a using-declarator names constructors only when its terminal name equals the last component of the nested-name-specifier -- so through an alias, the terminal name is read as the injected-class-name, i.e. a type, and Clang then demands `typename`. Clang is right here. Affects `hetero-data.hpp` (19 TUs) and `iter-source.hpp` (62 TUs); in the latter the alias is renamed `_I` -> `Adapter` while we are at it. Note `iter-source` as a whole awaits a design review, see #1125 * P1787R6 requires a template-argument-list after the `template` keyword. `holder.template emplace (...)` in `opaque-holder.hpp` and two sites in `node-builder.hpp` supply none, so the keyword has to go (83 TUs). * A default template argument may be given only once per scope. The out-of-class definition of `OutputSlot::AllocState` repeated the default from its declaration in 'output-slot.hpp' -- note the friend-declaration further down in the same header already got this right. * `constexpr auto ROUGH_PRECISION = pow (10, -3)` is not a constant expression by the standard; only GCC accepts it, through a builtin. Hence `util::ipow()` in 'util-quant.hpp', an exponentiation with integral exponent by square-and-multiply, as a counterpart to `ilog2()`. Exact for representable base and result, and the static_assert documents that `ipow(10.0,-3)` is bit-identical to `1e-3`. 193 TUs depended on this single line. Furthermore, two findings made while surveying: * `lib/stat/statistic.hpp` held a second, dormant instance of the same `pow` problem, in a `round<places>()` helper that nothing in Lumiera ever instantiates -- which is why Clang never saw it. Since the helper is also the naive and imprecise formulation, it is removed here; a note records that it stays in use upstream in yoshimi-test, where this header comes from, and that decimal rounding belongs to #1360 if ever wanted here. * The alias `DataBuilder` was defined twice, identically, in 'weaving-pattern-builder.hpp' and in 'node-builder.hpp' which includes the former. Both compilers tolerate the duplicate definition and only Clang objects to the repeated default argument, which is why this went unnoticed. The duplicate is dropped and its documentation moved to the surviving definition -- together with a @todo, since `DataBuilder`, `SizMark` and `UseHeapAlloc` are vocabulary of the node-builder DSL and reside where they do by accident of include order. |

Lumiera -- the video NLE for Linux ================================== Version: 0.pre.05~dev :Date: 11/2025 ************************************************************* Lumiera is a non-linear video editing and compositing tool. The Application will allow to edit footage using common multimedia formats and audio/video stream codecs. Lumiera features nondestructive editing, compositing tools, a selection of effects plugins, processing in RGB, YUV and RGB-float colour models and the ability to mix media with differing sizes and framerates. Lumiera is especially well suited for large and elaborate professional editing tasks with lots of material, several scenes, nested sequences, colour grading, 3D support, full fledged sound montage and multiple edit versions prepared in parallel. NOTE: as of 11/2025, Lumiera is in early development stage; it is not usable yet. The above describes the Lumiera project vision, the implementation of which will require many more years. Visit https://Lumiera.org and join the mailing list when interested in Lumiera planning and development. **************************************************************** Lumiera pre-Alpha Versions -------------------------- .This source tree doesn't contain a working video editing application yet. Rather, it contains the framework and technology core of the envisioned Application »Lumiera«. What we attempt to build here is innovative, and we must engage in a series of integration steps to search for suitable pathways towards our envisaged architecture. Since 2024, the integration of the Render Engine takes centre stage, in an effort to establish a steady state realtime processing and display pipeline, still relying on generated video data rather than using a library to read and playback a video file. - https://Lumiera.org/documentation/design/governance/integration.html[Integration steps] - See also https://issues.lumiera.org/roadmap[Project roadmap] Build Requirements ------------------ For building Lumiera, you'll need: * C++23 compiler GCC >=14 (Clang fails atm) * Git Version management system * https://www.scons.org/[SCons build system] * https://www.boost.org/[Boost libraries] * https://github.com/bplaum/gavl[GAVL library] * https://www.alsa-project.org/[ALSA (libasound2-dev)] * https://nobug.pipapo.org/[NoBug library] * https://gtkmm.gnome.org/en/[gtkmm] * https://cgit.freedesktop.org/xorg/lib/libXv[libXv] * https://wiki.gnome.org/Projects/LibRsvg[lib rSVG] * https://git.lumiera.org/gitweb?p=debian/gdl;a=summary[lib GDL] * https://git.lumiera.org/gitweb?p=debian/gdlmm;a=summary[GDL-mm bindings] Further information: * Online documentation at https://Lumiera.org/download.html[Build and install]. * Documentation is also available in-tree in 'doc/user/tutorials/building.txt' * Source code can be retrieved with `git clone git://git.lumiera.org/LUMIERA` Debian Package -------------- Hermann Vosseler (aka Ichthyo) maintains a *Debian* packaging of the source tree - the package definition can be pulled from `git://git.lumiera.org/debian/lumiera/` - the package can be built by `git-buildpackage`
