# OpenNI 2 is built with its own Makefile-based build system (no CMake/Meson).
# The upstream platform detection only knows x86 / x86_64 / arm32 and errors
# out on aarch64; Patch0 adds the aarch64 (Arm64) platform with neutral,
# SSE-free flags so the library and drivers build natively on aarch64.

%description
OpenNI 2 is a framework for acquiring, processing and understanding the output
of 3D sensors (depth and RGB). It exposes a C and C++ API for depth and color
streams, device enumeration, recording and playback.
This package is the ROS-bundled development package: it ships the core runtime
library (libOpenNI2.so), the bundled device-driver plugins and the public C/C++
headers, so that dependent packages can build against OpenNI 2.
%prep
%autosetup -p1
%build
# The upstream Makefile has no "install" target and only knows x86/x86_64/
# arm32; Patch0 makes aarch64 (Arm64) a supported native platform (no SSE,
# no -march flags; NEON fast paths fall back to the scalar reference code).
#
# Build order matters because the top-level Makefile only declares the
# cross-project dependency graph for its aggregate targets: XnLib (static
# helper) must be built first, then DepthUtils (static), then the core
# libOpenNI2.so, and finally the four device-driver plugins. Each stage is
# a separate make invocation so -j cannot reorder the stages.
#
# The Java wrapper, the GLUT-based NiViewer tool and the samples are
# intentionally not built: they would pull in a JDK and freeglut which this
# library package does not need.

* Thu Sep 24 2026 openEuler Builder <builder@openeuler.org> - 2.2.0-2
- Extend aarch64-support.patch: route __aarch64__ in XnPlatform.h to the
arch-neutral Linux-x86 platform header so the C++ build no longer hits
'#error Unsupported Platform' and the XnChar/XnUInt32/XnUInt64 typedefs
resolve. The original patch only taught the Makefile build system about
aarch64 (CommonDefs.mak + Platform.Arm64); the C++ header still fell
through to the unsupported-platform #error.
* Thu Sep 24 2026 openEuler Builder <builder@openeuler.org> - 2.2.0-1
- Initial package of OpenNI 2.2.0 for openEuler (aarch64 native build)
