[Description Liu Yujie 2024-06-07 00:49:16 UTC]

When trying to emerge media-gfx/inkscape-1.3.2-r2 on llvm profile with clang-18:
/tmp/portage/media-gfx/inkscape-1.3.2-r2/work/inkscape-1.3.2/src/3rdparty/2geom/include/2geom/path.h:846:20: error: no member named 'unique' in 'std::shared_ptr<Geom::PathInternal::PathData>'
  846 |         if (!_data.unique()) {
      |              ~~~~~ ^


there is already an upstream issue and exists possible fix

Patch works for me! Thanks!

Not sure if related, but also failing to build with gcc 13.3.1_p20241025:

/var/tmp/portage/media-gfx/inkscape-1.3.2-r2/work/inkscape-1.3.2/src/extension/internal/pdfinput/poppler-cairo-font-engine.cpp: In static member function ‘static CairoFreeTypeFont* CairoFreeTypeFont::create(const std::shared_ptr<GfxFont>&, XRef*, FT_Library, CairoFontEngine*, bool)’:
/var/tmp/portage/media-gfx/inkscape-1.3.2-r2/work/inkscape-1.3.2/src/extension/internal/pdfinput/poppler-cairo-font-engine.cpp:424:44: error: no matching function for call to ‘FoFiTrueType::make(fontchar, std::vector<unsigned char>::size_type)’

(...)

I didn't dig into this, just removed it from world and moved on with my update. Perhaps should have a dependency on app-text/poppler <= 24.08.0 ?

Unrelated and fixed in 1.4-r1.

Speaking of which, did anyone here test 1.4-r1 with clang-18 already?

[Comment 7 Michel Ganguin 2024-11-21 19:06:36 UTC]

Same error with 1.3.2. Building 1.4 with LLVM profile works for me, with the following USE flags:
