* Update eigen from v3.3.7 to v5.0.1.
This updates eigen from v3.3.7 released on December 11, 2018-12-11 to v5.0.1
released on 2025-11-11. There have be a large number of bug-fixes,
optimizations, and improvements between these releases. See the details at;
https://gitlab.com/libeigen/eigen/-/releases
It retains the previous custom minimal `CMakeLists.txt`, and adds a
README-OrcaSlicer.md that explains what version and parts of the upstream
eigen release have been included, and where the full release can be found.
* Update libigl from v2.0.0 (or older) to v2.6.0.
This updates libigl from what was probably v2.0.0 released on 2018-10-16 to
v2.6.0 released on 2025-05-15. It's possible the old version was even older
than that but there is no version indicators in the code and I ran out of
patience identifying missing changes and only went back as far as v2.0.0.
There have been a large number of bug-fixes, optimizations, and improvements
between these versions. See the following for details;
https://github.com/libigl/libigl/releases
I retained the minimal custom `CMakeLists.txt`, added `README.md` from the
libigl distribution which identifies the version, and added a
README-OrcaSlicer.md that details the version and parts that have been
included.
* Update libslic3r for libigl v2.6.0 changes.
This updates libslic3r for all changes moving to eigen v5.0.1 and libigl
v2.6.0. Despite the large number of updates to both dependencies, no changes
were required for the eigen update, and only one change was required for the
libigl update.
For libigl, `igl::Hit` was changed to a template taking the Scalar type to
use. Previously it was hard-coded to `float`, so to minimize possible impact
I've updated all places it is used from `igl::Hit` to `igl::Hit<float>`.
* Add compiler option `-DNOMINMAX` for libigl with MSVC.
MSVC by default defines `min(()` and `max()` macros that break
`std::numeric_limits<>::max()`. The upstream cmake that we don't include
adds `-DNOMINMAX` for the libigl module when compiling with MSVC, so we need
to add the same thing here.
* Fix src/libslic3r/TriangleMeshDeal.cpp for the unmodified upstream libigl.
This fixes `TriangleMeshDeal.cpp` to work with the unmodified upstream
libigl v2.6.0. loop.{h,cpp} implementation.
This file and feature was added in PR "BBS Port: Mesh Subdivision" (#12150)
which included changes to `loop.{h,cpp}` in the old version of libigl. This PR
avoids modifying the included dependencies, and uses the updated upstream
versions of those files without any modifications, which requires fixing
TriangleMeshDeal.cpp to work with them.
In particular, the modifications made to `loop.{h,cpp}` included changing the
return type from void to bool, adding additional validation checking of the
input meshes, and returning false if they failed validation. These added
checks looked unnecessary and would only have caught problems if the input
mesh was very corrupt.
To make `TriangleMeshDeal.cpp` work without this built-in checking
functionality, I removed checking/handling of any `false` return value.
There was also a hell of a lot of redundant copying and casting back and forth
between float and double, so I cleaned that up. The input and output meshs use
floats for the vertexes, and there would be no accuracy benefits from casting
to and from doubles for the simple weighted average operations done by
igl::loop(). So this just uses `Eigen:Map` to use the original input mesh
vertex data directly without requiring any copy or casting.
* Move eigen from included `deps_src` to externaly fetched `deps`.
This copys what PrusaSlicer did and moved it from an included dependency under
`deps_src` to an externaly fetched dependency under `deps`. This requires
updating some `CMakeList.txt` configs and removing the old and obsolete
`cmake/modules/FindEigen3.cmake`. The details of when this was done in
PrusaSlicer and the followup fixes are at;
* 21116995d7
* https://github.com/prusa3d/PrusaSlicer/issues/13608
* https://github.com/prusa3d/PrusaSlicer/pull/13609
* e3c277b9ee
For some reason I don't fully understand this also required fixing
`src/slic3r/GUI/GUI_App.cpp` by adding `#include <boost/nowide/cstdio.hpp>` to
fix an `error: ‘remove’ is not a member of ‘boost::nowide'`. The main thing I
don't understand is how it worked before. Note that this include is in the
PrusaSlicer version of this file, but it also significantly deviates from what
is currently in OrcaSlicer in many other ways.
* Whups... I missed adding the deps/Eigen/Eigen.cmake file...
* Tidy some whitespace indenting in CMakeLists.txt.
* Ugh... tabs indenting needing fixes.
* Change the include order of deps/Eigen.
It turns out that although Boost includes some references to Eigen, Eigen also
includes some references to Boost for supporting some of it's additional
numeric types.
I don't think it matters much since we are not using these features, but I
think technically its more correct to say Eigen depends on Boost than the
other way around, so I've re-ordered them.
* Add source for Eigen 5.0.1 download to flatpak yml config.
* Add explicit `DEPENDS dep_Boost to deps/Eigen.
I missed this before. This ensures we don't rely on include orders to make
sure Boost is installed before we configure Eigen.
* Add `DEPENDS dep_Boost dep_GMP dep_MPFR` to deps/Eigen.
It turns out Eigen can also use GMP and MPFR for multi-precision and
multi-precision-rounded numeric types if they are available.
Again, I don't think we are using these so it doesn't really matter, but it is
technically correct and ensures they are there if we ever do need them.
* Fix deps DEPENDENCY ordering for GMP, MPFR, Eigen, and CGAL.
I think this is finally correct. Apparently CGAL also optionally depends on
Eigen, so the correct dependency order from lowest to highest is GMP, MPFR, Eigen, and CGAL.

* Fixed an issue on Windows it failed to login Orca Cloud with Google account
Reduce the size of current and new JSONs by standardising them with 1 tab indentation instead of 4 spaces.
This effectively reduces the size by almost 20 MB.
| Current | New |
|---|---|
| 85.2 Mib | 67 Mib |
Used [JQ](https://jqlang.org/) `--tab` to automatically format every current JSON.
> [!NOTE]
> Some profiles had the arrays on the same line, but those created by Orca were in the standard format (each object below the previous one). In some cases, this increases the number of tabs due to the new lines, but the increase is negligible, and this way both the base profiles and those created by Orca maintain the same style.
* Add runtime display backend detection for Wayland support
Add LinuxDisplayBackend utility to detect X11 vs Wayland at runtime
using GDK_IS_X11_DISPLAY / GDK_IS_WAYLAND_DISPLAY macros. This is
the foundation for removing the forced GDK_BACKEND=x11 and enabling
native Wayland support.
- New files: LinuxDisplayBackend.hpp/.cpp with get_linux_display_backend(),
is_running_on_wayland(), and is_running_on_x11()
- Propagate wxHAVE_GDK_X11 / wxHAVE_GDK_WAYLAND from FindGTK3.cmake
as compile definitions to libslic3r_gui
- No-op on non-Linux platforms (returns Unknown / false)
* Fix Phase 1 code quality: pragma once, source ordering, static cache
* Make X11 initialization conditional for Wayland support
Remove the unconditional GDK_BACKEND=x11 force that blocked native
Wayland. Replace with conditional logic:
- EGL safety fallback: re-force X11 only when wxUSE_GLCANVAS_EGL is
off and WAYLAND_DISPLAY is set, with a warning log
- XInitThreads() only called when DISPLAY is set (X11 in use)
- __GLX_VENDOR_LIBRARY_NAME only set when DISPLAY is present (GLX-specific)
- WEBKIT_DISABLE_COMPOSITING_MODE only set under XWayland (both
DISPLAY and WAYLAND_DISPLAY present)
- Guard X11/Xlib.h include with __has_include for robustness
- Restore display validation to accept either DISPLAY or WAYLAND_DISPLAY
This is Phase 2 of the Wayland support plan.
* Fix Phase 2: safer EGL macro check, add clarifying comments
* Add GLAD2 library and replace GLEW linkage in build system
Set up GLAD2 as a static library to replace GLEW for OpenGL loading.
GLAD2 supports both GLX and EGL, which is required for Wayland support.
- Create src/glad/ with pre-generated GLAD2 sources (GL 4.6 compat)
- Add src/glad/CMakeLists.txt building glad as a static library
- Wire glad into src/CMakeLists.txt before libvgcode
- Modify libvgcode to use shared glad for GL path (keeps local copy
only for GLES2/Emscripten) to avoid duplicate symbol conflicts
- Replace GLEW::GLEW with glad in libslic3r_gui link libraries
Note: GLEW is kept in deps for OpenCSG. Code migration from GL/glew.h
to glad/gl.h headers will follow in Phase 3B+3C.
* Fix Phase 3A+3D: libvgcode GLAD include, dead files, dlopen dep, OpenGL link var
* Migrate from GLEW to GLAD: replace headers and API calls across codebase
Replace all #include <GL/glew.h> with <glad/gl.h> across 49 source files.
Migrate GLEW API calls to GLAD equivalents:
- glewInit/glewExperimental -> gladLoaderLoadGL()
- GLEW_EXT_* / GLEW_ARB_* extension checks -> GLAD_GL_EXT_* / GLAD_GL_ARB_*
- Remove GLEW-specific EGL/GLX mismatch #error guards (not needed with GLAD)
- Replace unavailable EXT symbols with core GL equivalents in
GLCanvas3D.cpp (GL_MAX_SAMPLES, glRenderbufferStorageMultisample,
glBlitFramebuffer, GL_READ/DRAW_FRAMEBUFFER)
- Update log messages from glewInit to gladLoadGL
* Fix Phase 3B+3C: remove GLEW find, clean EXT symbols, update attribution
- Remove find_package(GLEW) block from root CMakeLists.txt since GLEW
is no longer linked by any main application code
- Remove "glew" from SLIC3R_STATIC option description
- Replace all remaining EXT framebuffer symbols with core equivalents
in render_thumbnail_framebuffer_ext and _rectangular_selection_picking_pass
- Update AboutDialog credits from GLEW to GLAD
* Enable EGL in wxWidgets and add runtime GLX/EGL selection for Wayland
- Set wxUSE_GLCANVAS_EGL=ON in wxWidgets build and Flatpak manifest
- Add PreferGLX() call on X11 sessions for driver compatibility
- Remove Phase 2 safety fallback (EGL is now always compiled in)
- Guard SwapBuffers against hidden canvases to prevent Wayland stalls
* Fix Phase 4: move PreferGLX to app startup, fix FPS counter guard
Move wxGLCanvas::PreferGLX() from OpenGLManager::create_wxglcanvas()
(static initializer) to GUI_App::on_init_inner() before any wxGLCanvas
is constructed. This prevents a race where SkipPartCanvas could trigger
wxGLBackend::Init() before the GLX preference is set. The new location
also adds explicit is_running_on_wayland() detection with a warning for
unknown backends.
Move increment_fps_counter() inside the IsShownOnScreen() guard so FPS
is only counted when a frame is actually swapped.
* Update GLFW from 3.3.7 to 3.4 for runtime Wayland/X11 backend selection
Replace the compile-time GLFW_USE_WAYLAND flag (which locked to a single
backend) with GLFW 3.4's GLFW_BUILD_WAYLAND + GLFW_BUILD_X11 flags that
build both backends and auto-select at runtime based on the available
display server. This enables the CLI thumbnail renderer to work on both
Wayland and X11 sessions without separate builds.
* wayland: Fix UI call sites that rely on global screen coordinates
On Wayland, wxGetMousePosition() returns (0,0) and SetPosition() is a
no-op for top-level windows. Fix the highest-impact call sites:
- GLCanvas3D: Use cached m_mouse.position from event handlers instead
of wxGetMousePosition() + ScreenToClient() in get_local_mouse_position()
- Plater: Use event-relative coords via ClientToScreen(e.GetPosition())
instead of wxGetMousePosition() in 3 leave-window handlers
- BBLTopbar: Use event.GetPosition() and FindToolByPosition() directly
in mouse handlers instead of wxGetMousePosition()/FindToolByCurrentPosition()
- Search: Use focus-based dismiss logic on Wayland instead of
wxGetMousePosition()-based rect checks in SearchDialog and
SearchObjectDialog
- GUI_App: Skip SetPosition() in window_pos_restore() on Wayland where
it is a no-op; still restore size and maximize state
- Button: Position tooltip relative to button widget via ClientToScreen
instead of wxGetMousePosition()
* Fix SearchDialog Wayland dismiss: guard against search_line focus
* flatpak: Add Wayland socket permission for native Wayland support
* spec
* Fix crash on Wayland when wxWidgets lacks EGL support
Restore the safety fallback that forces GDK_BACKEND=x11 when wxWidgets
was not built with wxUSE_GLCANVAS_EGL=ON. Without this, the GLX backend
tries to access a non-existent X11 display on native Wayland, crashing
in wxGLCanvas::IsDisplaySupported() with SIGSEGV at offset 0xe4.
Also add a defense-in-depth guard in detect_multisample() that skips
the IsDisplaySupported call entirely on Wayland without EGL.
Root cause: deps/wxWidgets must be rebuilt after enabling EGL. The
compile-time check in OrcaSlicer.cpp detects the mismatch and falls
back safely.
* Fix EGL detection: use wxHAS_EGL instead of wxUSE_GLCANVAS_EGL
wxUSE_GLCANVAS_EGL is a CMake build option, NOT a C++ preprocessor
macro. The actual macro defined in wxWidgets setup.h is wxHAS_EGL.
All compile-time EGL checks were using the wrong macro, causing
the safety fallback to always trigger even with a properly built
EGL-enabled wxWidgets.
* Fix GL function pointers invalidated on Wayland/EGL
gladLoaderLoadGL() dlopen's libGL.so.1 to resolve GL function pointers
via dlsym, then immediately dlclose's the handle. On X11/GLX this is
fine because the GLX context keeps libGL.so mapped. On Wayland/EGL,
nothing else holds libGL.so open, so dlclose unmaps it and all function
pointers become dangling — causing SIGSEGV on the first GL call.
Fix: on Wayland, use gladLoadGL(eglGetProcAddress) which resolves
function pointers through the EGL loader without opening/closing
libGL.so.
* fix crash on start and various rendering issues
* fix crash on close
* small refactor
* move GPU selection to desktop file
* clean up a bit
* clean up more
* fix appimage error
- add a new mode to build in docker
- Improve AppImage
1. fix libbz2 soname differeence issue on appimage
2. Downgrade to 22.04 for better compatibility
3. improve appimage overall
Add the localization/ directory to the Flatpak source list so
run_gettext.sh can compile .po files into .mo translations.
Replace LC_ALL=C.UTF-8 with LC_NUMERIC=C in the entrypoint script
to preserve the user's language settings while still preventing
decimal-separator parsing issues.
* Fix GIT_COMMIT_HASH not set in Flatpak builds
The env var check was gated inside the .git directory check, so
Flatpak builds (which exclude .git from the sandbox) always fell
back to "0000000". Lift the env var check to top level and inject
the commit hash into the Flatpak manifest via build-options.env.
* Switch Flatpak build to Clang/LLD via LLVM 21 SDK extension
- Add org.freedesktop.Sdk.Extension.llvm21
- Bump runtime to GNOME 49 (SDK 25.08) for llvm21 availability
* fix build errors and improving build speed for flatpak
* fxi more build errors
* Update error messages for GNOME Platform and SDK versions
* Get libslic3r tests closer to passing
I can't get geometry tests to do anything useful. I've added extra
output, but it hasn't helped me figure out why they don't work
yet. That's also probably the last broken 3mf test doesn't work.
The config tests were mostly broken because of config name changes.
The placeholder_parser tests have some things that may-or-may-not
still apply to Orca.
* Vendor a 3.x version of Catch2
Everything is surely broken at this point.
* Allow building tests separately from Orca with build_linux.sh
* Remove unnecessary log message screwing up ctest
Same solution as Prusaslicer
* Make 2 TriangleMesh methods const
Since they can be.
* Move method comment to the header where it belongsc
* Add indirectly-included header directly
Transform3d IIRC
* libslic3r tests converted to Catch2 v3
Still has 3 failing tests, but builds and runs.
* Disable 2D convex hull test and comment what I've learned
Not sure the best way to solve this yet.
* Add diff compare method for DynamicConfig
Help the unit test report errors better.
* Perl no longer used, remove comment line
* Clang-format Config.?pp
So difficult to work with ATM
* Remove cpp17 unit tests
Who gives a shit
* Don't need explicit "example" test
We have lots of tests to serve as examples.
* Leave breadcrumb to enable sla_print tests
* Fix serialization of DynamicConfig
Add comments to test, because these code paths might not be even used
anymore.
* Update run_unit_tests to run all the tests
By the time I'm done with the PR all tests will either excluded by
default or passing, so just do all.
* Update how-to-test now that build_linux.sh builds tests separately
* Update cmake regenerate instructions
Read this online; hopefully works.
* Enable slic3rutils test with Catch2 v3
* Port libnest2d and fff_print to Catch2 v3
They build. Many failing.
* Add slightly more info to Objects not fit on bed exception
* Disable failing fff_print tests from running
They're mostly failing for "objects don't fit on bed" for an
infinite-sized bed. Given infinite bed is probably only used in tests,
it probably was incidentally broken long ago.
* Must checkout tests directory in GH Actions
So we get the test data
* Missed a failing fff_print test
* Disable (most/all) broken libnest2d tests
Trying all, not checking yet though
* Fix Polygon convex/concave detection tests
Document the implementation too. Reorganize the tests to be cleaner.
* Update the test script to run tests in parallel
* Get sla_print tests to build
Probably not passing
* Don't cause full project rebuild when updating test CMakeLists.txts
* Revert "Clang-format Config.?pp"
This reverts commit 771e4c0ad2.

* Actually build tests on Linux and allow RelWithDebInfo
They weren't being built.
Also cleaned up --config flags which enables RelWithDebInfo on Linux,
now that Ninja Multi-Config is used, it's quite trivial.
* Remove obsolete Slic3r Perl tests
The directory doesn't exist, they're already gone.
* Add GH job for running unit tests
* Move unit test execution to script and upload test results
* Don't run scheduled builds on forks
* Only deploy from SoftFever/OrcaSlicer
Will stop failures on forks
* Use artifact instead of cache
* Tweak archive and checkout paths
Keep getting error:
```
/home/runner/work/_temp/902d0a0a-6d23-4fe0-a643-8b5cc4efd25b.sh: line 1: scripts/run_unit_tests.sh: Permission denied
```
That seems to be because I didn't use actions/checkout, the working
directory is never setup correctly? So using checkout to get scripts
directory. Unsure if archive will preserve the `build/tests/` prefix;
will find out soon.
* Use tar to package directory and write results to correct directory
Tar preserves filenames and directory structure
* Use tar -xvf not -xzf
Muscle memory failed me
* Add testing wiki page
* Save test logs on failure and choose correct directory for junit
* Consolidate apt install steps, use for unit tests too, disable non-Linux builds
Temporarily disable non-Linux builds to save time while developing
this.
Cache the apt packages to save some time searching apt and downloading
them again (though I realize this is also downloading, but hopefully
by something closer and faster).
Remove all the redundant packages listed in the workflow and debian
distribution lists.
* Remove apt install steps from workflow
`./build-linux.sh -u` is supposed to install all needed packages, so
it should build without needing anything besides that. If I'm wrong
this commit will be dropped.
* Need composite action checked out locally
* Re-enable non-Linux builds now that it's working
* Skip a deploy and a notarize in forks
They only succeed in the main repo.
* Fix multi-build for non-Release builds: share CONFIG
* Correct build errors in unit tests
Indeterminate method signatures resolved. Updated script to build all
the tests.
* Fix -g vs -e for RelWithDebInfo
* Change CONFIG->BUILD_CONFIG
Missed one in prior commits
* Reduce wasteful redundant build artifact copies
1. Don't copy the artifacts and leave them; make a hard link first;
only make a copy only while creating AppImage.
2. Don't tar up the `package` directory; nothing uses this tar AFAICT
* Fix directory name
* Change jigsaw auth test URLs to httpbin.org
No idea why the basic auth doesn't work, but it doesn't work for
`curl` CLI either. This does.
* Remove force-build
It got reverted at
e3f049829b
for unknown reasons.
* Add timeout for unit tests in GitHub Actions workflow (#11146)

Move many third-party components' source codes from the src folder to a new folder called deps_src. The goal is to make the code structure clearer and easier to navigate.
