py10x-fin-base-cxx (cxxfin import)
Native extension for py10x-fin-base. Dist name is py10x-fin-base-cxx; the import
module remains cxxfin. Install py10x-fin-base (not this package directly).
Built with pybind11 and scikit-build-core.
Architecture
cxxfin.cpp— pybind11 module source;PYBIND11_MODULEname iscxxfingenerate_stubs.py— post-build stub generation; promotespy10x_kerneltoRTLD_GLOBALbefore importingcxxfinso thatBTraitabletypeinfo is visible (macOS flat namespace requirement)- Headers fetched from
cxx10xat the exact git commit matching the installedpy10x_kernelbinary (version string contains the hash)
Subclassing py10x_kernel types
py10x_kernel is built with CXX_VISIBILITY_PRESET default so its vtables and typeinfo are exported. On import it promotes itself to RTLD_GLOBAL via dladdr + dlopen(RTLD_NOW | RTLD_GLOBAL | RTLD_NOLOAD), making its symbols visible to subsequently loaded extension modules. py10x_kernel must be imported before cxxfin — this holds in normal usage since it is always loaded as part of the py10x-core import chain.
Incremental, automatic rebuild
cxxfin is automatically rebuilt on import cxxfin whenever the sources changed.
Clean rebuild
Needed when changing build structure, e.g. adding source files, editing CMakeLists.txt):
uv pip uninstall py10x-fin-base-cxx
rm -rf .venv/py10x-build/cxxfin
uv sync --reinstall-package py10x-fin-base-cxx
uv pip uninstall py10x-fin-base-cxx— removes the editable finder from site-packages, which otherwise interceptsimport cxxfinduring stub generation and causes a circular rebuild failurerm -rf .venv/py10x-build/cxxfin— wipes the stale CMake cacheuv sync --reinstall-package py10x-fin-base-cxx— rebuilds and reinstalls from scratch
Normal development (edit C++ source → run) does not require this; the editable rebuild fires automatically on import.
Debug build
cxxfin builds Release by default. For Debug build, set the build type via
scikit-build-core's env override and re-run uv sync, for example:
SKBUILD_CMAKE_BUILD_TYPE=Debug uv sync --reinstall-package py10x-fin-base-cxx
The build type is fixed at sync time (baked into the editable install along with the
build-dir), so switching is just another sync — SKBUILD_CMAKE_BUILD_TYPE=Debug uv sync --reinstall-package py10x-fin-base-cxx
for Debug, plain uv sync --reinstall-package py10x-fin-base-cxx for Release. Because each type has its own
tree under .venv/py10x-build/cxxfin/<Debug|Release>/, switching does not rebuild from
scratch.
