Root cause: openyxdb's export macros (OPEN_ALTERYX_EXPORT, BASE_EXPORT, STRING_EXPORT, etc.) expand to nothing when BUILDING_OPEN_ALTERYX is defined, to __declspec(dllexport) when building an actual DLL (OPEN_ALTERYX_EXPORTS), and to __declspec(dllimport) otherwise. The openyxdb library target and the nanobind Python module both define BUILDING_OPEN_ALTERYX explicitly, but openyxdb_tests/openyxdb_example did not - so on Windows those two consumers saw every class as dllimport while linking against a plain STATIC archive (the default when OPENYXDB_BUILD_PYTHON=ON), which has no import thunks to satisfy those references, producing LNK2019 unresolved externals for every exported symbol. Fix: define BUILDING_OPEN_ALTERYX for both test targets whenever OPENYXDB_BUILD_PYTHON is ON, matching what the library and the Python module already do. Verified locally on Linux in both configurations (OPENYXDB_BUILD_PYTHON=ON default, and standalone OPENYXDB_BUILD_PYTHON=OFF shared-lib build) - 25/25 tests pass in both. --- CMakeLists.txt | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/CMakeLists.txt b/CMakeLists.txt index 655c14b..408f0f2 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -123,6 +123,15 @@ if(OPENYXDB_BUILD_TESTS) add_executable(openyxdb_example test/main.cpp) target_include_directories(openyxdb_example PRIVATE ${CMAKE_SOURCE_DIR}/include) target_compile_definitions(openyxdb_example PRIVATE UNICODE NOMINMAX) + # openyxdb's headers gate __declspec(dllimport) on Windows behind + # BUILDING_OPEN_ALTERYX/OPEN_ALTERYX_EXPORTS (see include/Open_AlteryxYXDB.h + # and friends).

On windows-latest, CMake's default generator selection falls back to guessing a Visual Studio version by name ("Visual Studio 17 2022"), which doesn't match the VS 18 Enterprise actually installed on the runner, so configure fails with "could not find any instance of Visual Studio" even though msvc-dev-cmd set up the environment correctly. test-cpp's pixi task already sidesteps this by passing -G Ninja directly to its own `cmake -B build` invocation. Apply the same fix here via scikit-build-core's cmake.args, which it passes straight through to the underlying `cmake` invocation - Ninja is already a pixi dependency, so no new tooling is needed. Verified locally on Linux: clean `pixi run test-python` rebuild still passes 47/47 (1 skipped) with the explicit generator. --- pyproject.toml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/pyproject.toml b/pyproject.toml index 899e6bd..83d7aac 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -49,7 +49,7 @@ test = [ [tool.scikit-build] cmake.build-type = "Release" -cmake.args = ["-DOPENYXDB_BUILD_TESTS=OFF"] +cmake.args = ["-GNinja", "-DOPENYXDB_BUILD_TESTS=OFF"] wheel.packages = ["python/openyxdb"] [tool.scikit-build.cmake.define] From 32719097497d9d098d45533e758de800450a5d57 Mon Sep 17 00:00:00 2001 From: Nathan Riley Date: Sun, 19 Jul 2026 07:11:49 +0000 Subject: [PATCH 5/7] fix: scope the Ninja-generator fix to ci.yml, revert pyproject.toml pyproject.toml's [tool.scikit-build] cmake.args is global build config - it also drives publish.yml's cibuildwheel wheel build, not just ci.yml's test-python job. Forcing -GNinja there (253efbc) fixed test-python but changed how the Windows wheel's extension module gets linked/placed, breaking cibuildwheel's own test step with "ImportError: DLL load failed while importing _openyxdb: The specified module could not be found" - a real behavioral difference in the published wheel, not just config noise. Revert pyproject.toml to its pre-253efbc state (no explicit generator; publish.yml keeps whatever generator selection has always worked for the shipped wheels) and instead set CMAKE_GENERATOR=Ninja as a step-scoped env var on ci.yml's "Run Python tests" step only, which scikit-build-core reads the same way. This keeps the fix contained to the test job and out of the release build path entirely.

Root cause: conda-forge's vc-feedstock activation script (pulled in by pixi's cxx-compiler on win-64) unconditionally sets CMAKE_GENERATOR_PLATFORM=x64 alongside CMAKE_GENERATOR whenever CMAKE_GENERATOR_PLATFORM is empty - it doesn't check whether the resolved generator actually supports a platform argument, so it stomps on our Ninja override too, and scikit-build-core forwards that env var straight to cmake, which then rejects it. Switch to CMAKE_ARGS=-GNinja instead: scikit-build-core detects the "-G" token in CMAKE_ARGS and passes it straight through as a CLI argument to cmake (see scikit_build_core/cmake.py's get_generator/ configure), the same mechanism test-cpp's pixi task already uses successfully (`cmake -B build -G Ninja ...`) - CMake's CLI -G always wins over any CMAKE_GENERATOR/CMAKE_GENERATOR_PLATFORM env vars still present from the activation script, sidestepping the conflict entirely.
