You are building ONE PySide6 Qt-module binding as a STATIC wasm archive for the FreeCAD WebAssembly build. The full pipeline is ALREADY PROVEN this session (M0 shiboken runtime + M1 QtCore value-types + libpyside all compile/link/run in wasm). Your job is mechanical: generate + cross-compile your module and produce lib<Module>_wasm.a exporting PyInit_<Module>. Iterate on compile errors. PATHS (all real): - Host shiboken generator: /opt/toolchains/pyside-host/bin/shiboken6 (v6.11.0) - PySide source: /tmp/pyside-setup/sources/pyside6 (PySide6/<Module>/ has typesystem_<x>.xml + <Module>_global.h[.in]); shiboken runtime src /tmp/pyside-setup/sources/shiboken6 - shiboken generated headers (already built): /home/magik6k/lcad-wasm/pyside-port/build/shiboken-wasm-inc (has sbkversion.h + embed/signature_*_inc.h) - libpyside src (headers to compile against): /tmp/pyside-setup/sources/pyside6/libpyside - emscripten: source /opt/toolchains/emsdk/emsdk_env.sh ; emcc 4.0.12 - wasm Qt: QT=/opt/toolchains/qt-asyncify/6.11.1/wasm_singlethread ; QTINC=$QT/include ; host moc=/opt/toolchains/qt/6.11.1/gcc_64/libexec/moc - wasm python headers: /opt/toolchains/python-wasm/include/python3.14 THE PROVEN COMPILE INCLUDE SET (use verbatim; add sibling-module private paths as needed): QTFLAGS for QtCore: -I$QTINC -I$QTINC/QtCore -I$QTINC/QtCore/6.11.1 -I$QTINC/QtCore/6.11.1/QtCore -I$QT/mkspecs/wasm-emscripten For QtGui also add: -I$QTINC/QtGui -I$QTINC/QtGui/6.11.1 -I$QTINC/QtGui/6.11.1/QtGui For QtWidgets also add: -I$QTINC/QtWidgets -I$QTINC/QtWidgets/6.11.1 -I$QTINC/QtWidgets/6.11.1/QtWidgets (plus QtGui + QtCore paths) EMFLAGS="-fexceptions -O2 -DNDEBUG -std=c++17 -DSHIBOKEN_NO_EMBEDDING_PYC=1" INCS: -I<gen-out>/PySide6/<Module> -I/home/magik6k/lcad-wasm/pyside-port/build/shiboken-wasm-inc -I<that>/embed -I/opt/toolchains/python-wasm/include/python3.14 -I/tmp/pyside-setup/sources/shiboken6/libshiboken -I/tmp/pyside-setup/sources/pyside6/libpyside $QTFLAGS GENERATION (host libclang parses the WASM Qt headers so the AST matches target; NO --compiler-path, it makes a bad triple): $GEN --generator-set=shiboken --enable-parent-ctor-heuristic --enable-return-value-heuristic --use-isnull-as-nb-bool --avoid-protected-hack --api-version=6.11 --include-paths="$QTINC:$QTINC/QtCore[:$QTINC/QtGui:...]:/tmp/pyside-setup/sources/shiboken6/libshiboken:/tmp/pyside-setup/sources/pyside6/libpyside:<gen-inc>" --typesystem-paths="/tmp/pyside-setup/sources/pyside6/PySide6" --output-directory=<gen-out> <Module>_global.h PySide6/<Module>/typesystem_<x>.xml The module global header may be <Module>_global.h.in needing configure — or just write a minimal <Module>_global.h that #includes the module umbrella header (e.g. #include <QtWidgets/QtWidgets>). typesystem package MUST be "PySide6.<Module>" so PyInit_<Module> + the module-import strings line up. KNOWN FIXES (apply as errors demand): - A generated wrapper's __repr__ uses QBuffer+QDebug -> add per-type <extra-includes><include file-name="QBuffer" location="global"/><include file-name="QDebug" location="global"/></extra-includes> in a LOCAL COPY of the typesystem (copy the module dir, edit, point --typesystem-paths at your copy first). OR add the includes to your module global header. - Files that '#include "X.moc"' need: $MOC $QTFLAGS X.cpp -o <out>/X.moc, then -I<out>. - EXCLUDE numpy-gated files (*numpy*). - -no-feature-thread: QThread/QMutex are absent; the QtCore typesystem is already guarded (only QBasicReadWriteLock/QReadWriteLock warn — harmless). Widgets/Gui don't use threads. - If a specific class/method fails to compile and is niche, drop it: <object-type name="X"> ... <modify-function signature="..." remove="all"/> or omit the type. Prefer generating the FULL real typesystem first (known-good); only trim to fix hard errors. Size is secondary to a working archive. - Compile wrappers in PARALLEL (many independent .cpp): background emcc jobs or xargs -P. SUCCESS = lib<Module>_wasm.a exists and 'emnm' shows 'T PyInit_<Module>'. Write your exact working build script to /home/magik6k/lcad-wasm/pyside-port/m2-<module>/build.sh and the archive to /home/magik6k/lcad-wasm/pyside-port/build/m2-<module>/. Capture the final compile status (how many wrapper .o built, any files you had to drop and why). === YOUR MODULE: QtWidgets (slug m2-qtwidgets) === typesystem_widgets.xml. Depends on QtGui + QtCore. Largest module (QApplication/QWidget/QMainWindow/...). This is what FreeCAD getMainWindow() returns (QMainWindow). Needs QtWidgets+QtGui+QtCore private headers. Expect it to be big; get the archive built even if you must drop a few niche widget classes (record them). Gen output dir: /home/magik6k/lcad-wasm/pyside-port/build/m2-qtwidgets/gen ; archive: /home/magik6k/lcad-wasm/pyside-port/build/m2-qtwidgets/libQtWidgets_wasm.a . Return the schema.

I'm seeing the structure for QtWidgets_global.h now—it needs the core namespace header and the debug macro, followed by the main QtWidgets include, with no additional post-header content since QtWidgets isn't in the global files list.

For the typesystem setup, QtWidgets depends on QtGui and QtCore, so I need to load their typesystems and point the typesystem paths to the PySide6 directory to find them. The key issue is that shiboken will generate references to headers like `pyside6_qtgui_python.h` and `pyside6_qtcore_python.h`, but since I'm not building those modules here, those generated headers won't exist—I'll need to handle that dependency somehow when compiling the QtWidgets wrapper c  …

The issue is that when QtCore uses a reduced type system with only QObject, the generated header file lacks type indices for other types like QString and QRect that QtWidgets wrappers need to reference. This causes compilation failures because those indices don't exist in the reduced build.

To compile QtWidgets, I need the full generated headers from both QtCore and QtGui with all their type indices included. When shiboken generates QtWidgets, it includes the QtCore and QtGui headers and references their type indices, but those come from building those modules separately first. The M1 QtCore being reduced means those indices were never generated in the first place.

The solution is to gener  …

The typesystem_widgets.xml loads QtGui and QtCore with generate="no", so when I generate QtWidgets, shiboken only creates QtWidgets wrappers but references the type indices from QtGui and QtCore in the generated header files. This means I need to generate the full QtGui and QtCore bindings first with matching typesystems to ensure those indices exist and align properly.

Since shiboken assigns indices deterministically per module based on the loaded typesystem, generating QtCore and QtGui separately produces the same index enums that QtWidgets expects—this mirrors how the real build works with three separate shiboken invocations. The -no-feature-thread caveat shouldn't be a problem since the  …

The template files are referenced relative to the PySide6 source directory, so I need to make sure the `--typesystem-paths` argument includes `/tmp/pyside-setup/sources/pyside6/PySide6` so that paths like `templates/common.xml`, `QtGui/typesystem_gui.xml`, `QtCore/typesystem_core.xml`, and `QtWidgets/typesystem_widgets_common.xml` can all be resolved correctly.

For the full build, I'll point directly at the PySide6 source directory instead of using a local copy like the M1 approach did. If I need to add extra includes for `__repr__` types, I can add those to my global headers instead of maintaining a separate typesystem copy.

I need to add the PySide6 helper headers directory to the include paths for both generation and compilation, and I'm verifying that qiopipe.h is present there. The compilation issues for QtCore and QtGui don't matter since I only need the generated pyside6_qt*_python.h headers.

I'm realizing that generation and compilation are separate — shiboken's libclang just needs to parse the global headers during generation, but they don't need to compile with emcc. So I'll generate QtCore, QtGui, and QtWidgets all into the same output directory so their relative includes align properly, then grab the python.h headers from each.

I need to adjust the typesystem file path since it's relative to the typesystem-paths directory, which already includes PySide6—so I should pass just `QtCore/typesystem_core.xml` rather than the full path. Let me use the absolute path for the typesystem file argument instead.

QtCore generation is complete with the full type indices in the header file, so I'm moving on to generate QtGui next.
Fable
QtCore full generation works. Now QtGui.

I need to track down the emscripten sysroot include path so that libclang can locate the GLES3/gl3.h header that QtGui requires. The M1 build already referenced EM_SYSROOT, so I should look for how that's configured.
Fable
QtGui needs GLES3 headers from emscripten sysroot. Let me locate them.

Fable

I'm going to add the emscripten sysroot include path to the generation process for GLES3 support, even though it might pull in conflicting system headers. Since the generation uses host libclang, adding `$EMSDK/upstream/emscripten/cache/sysroot/include` to the include paths should be safe. Let me regenerate QtGui with this addition.

Now I'm retrying the GUI generation.
