FreeCAD Web Dependency Boundary

Scope

This report records the FW-P0-005 probes against the locked dependency sources and the current Emscripten toolchain. A successful dependency probe does not mean that the FreeCADBase or FreeCADApp targets are WebAssembly complete.

Dependency	Locked source	Probe result	Evidence
QtCore / QtXml	Qt 5.15.13	Configure and wasm static archive build passed	`build-web/qt-probe/lib/libQt5Core.a`, `build-web/qt-probe/lib/libQt5Xml.a`
CPython	Python 3.12.3	Cross configure passed for `wasm32-unknown-emscripten`	`build-web/python-probe/Makefile`, `build-web/python-probe/pyconfig.h`
PyCXX	PyCXX 7.1.11	Four C/C++ bridge sources compiled to wasm objects	`build-web/pycxx-probe/*.o`

Reproduction

Qt was configured with the checked-in wasm-emscripten mkspec and then only the Core/XML targets were built:

FreeCAD/FreeCADBaseLib/sources/src/Qt-5.15.13/qtbase/configure \
  -xplatform wasm-emscripten -opensource -confirm-license -release -static \
  -no-feature-thread -nomake examples -nomake tests \
  -prefix FreeCAD/freecad-source/build-web/qt-install
make -C FreeCAD/freecad-source/build-web/qt-probe/src --jobs=8 sub-xml

The configure summary reports that Qt 5.15.13 recommends Emscripten 1.39.8, while this workspace uses Emscripten 3.1.6. The mismatch is a compatibility warning, not a hidden exact-compatibility claim. file reports representative objects from both archives as WebAssembly MVP modules.

CPython was configured using its checked-in wasm build instructions:

CONFIG_SITE=FreeCAD/FreeCADBaseLib/sources/src/Python-3.12.3/Tools/wasm/config.site-wasm32-emscripten \
  emconfigure FreeCAD/FreeCADBaseLib/sources/src/Python-3.12.3/configure -C \
  --host=wasm32-unknown-emscripten --build=x86_64-pc-linux-gnu \
  --with-emscripten-target=browser --with-build-python=/usr/bin/python3.12 \
  --without-ensurepip

The generated Makefile records MACHDEP=emscripten, SOABI=cpython-312-wasm32-emscripten, and PY_ENABLE_SHARED=0. The CPython runtime itself has not yet been compiled; a native build-Python and a later runtime build remain required.

PyCXX 7.1.11 sources cxx_extensions.cxx, cxxsupport.cxx, IndirectPythonInterface.cxx, and cxx_exceptions.cxx compile cleanly with em++ against the generated CPython headers. file confirms all four objects are WebAssembly modules.

Blocking boundary

The current FreeCAD CMake still calls find_package(Python3 COMPONENTS Interpreter Development REQUIRED) and find_package(Qt5 ... REQUIRED) for the FreeCADBase/FreeCADApp graph. The Web configuration currently has no installed Emscripten Python development package or Qt CMake package wired into those lookups. The first full-core configure is also stopped earlier by the missing yaml-cpp CMake package, as recorded in freecad-web-core-configure.log.

Consequently, this task establishes usable Qt/Python/PyCXX source boundaries and evidence, but does not promote FreeCADBase, FreeCADApp, Document, or Python integration to exact.
