# 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.
#
# topdir: libopenni2-dev-2.2.0
#
# The upstream Makefile builds Release with -O2 -DNDEBUG and deliberately no
# -g, so the produced .so files carry no DWARF debug info. mock's
# find-debuginfo therefore cannot emit any source mapping, leaving
# debugsourcefiles.list empty, which rpmbuild treats as a hard
# "Empty %files file" error. Disable the debug/debugsource subpackages:
# there are no symbols to ship anyway, so nothing useful is lost.

%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.

* Mon Sep 28 2026 openEuler Builder <builder@openeuler.org> - 2.2.0-5
- Disable the debug/debugsource subpackages with %%define debug_package
%%{nil}. Build 113193 finally compiled, linked and installed all artefacts
(libOpenNI2.so + the four driver plugins + headers) on aarch64, but the
build then failed at debuginfo packaging with "error: Empty %%files file
.../debugsourcefiles.list". Root cause: the upstream Makefile builds
Release with -O2 -DNDEBUG and no -g, so the .so files carry no DWARF
symbols (the gdb-add-index stage logged "No debugging symbols" for all
five .so files); find-debuginfo can't emit any source mapping, leaving
debugsourcefiles.list empty. As there are no symbols to ship anyway,
disabling the debug subpackages loses nothing and resolves the hard
error. This is a no-op on any other arch / chroot (a global spec macro).
* Mon Sep 28 2026 openEuler Builder <builder@openeuler.org> - 2.2.0-4
- Fix aarch64-support.patch: the Include/OniPlatform.h hunk header was
miscounted (@@ -42,6 +42,10 @@ claimed 6 context / 10 total lines but
the body actually has 5 context + 4 added = 9 lines). GNU patch rejected the
hunk at %prep ("1 out of 1 hunk FAILED -- saving rejects to OniPlatform.h.rej")
so build 113192 never reached %build. Corrected the header to
@@ -42,5 +42,9 @@; the aarch64 branch insertion is unchanged and applies
cleanly (verified locally). The hunk content is __aarch64__-guarded so this
is a no-op on any other arch.
* Mon Sep 28 2026 openEuler Builder <builder@openeuler.org> - 2.2.0-3
- Extend aarch64-support.patch: add __aarch64__ branch to the public API
header Include/OniPlatform.h (same pattern as the XnPlatform.h fix in -2).
The previous round only patched the XnLib internal header XnPlatform.h;
the public OniPlatform.h still had no __aarch64__ branch, so DepthUtils.cpp
(which includes OniCTypes.h -> OniPlatform.h) hit '#error Unsupported
Platform' and ONI_CALLBACK_TYPE/uint*_t stayed undefined.
* Mon Sep 28 2026 openEuler Builder <builder@openeuler.org> - 2.2.0-2
- Extend aarch64-support.patch: add __aarch64__ branch to XnPlatform.h so the
C/C++ platform-abstraction header includes the Linux-x86 types header
(XnChar, XnUInt32, XN_INVALID_FILE_HANDLE, ...). The previous patch only
handled the Makefile-level platform detection; the C preprocessor still
hit "#error Unsupported Platform" and every type stayed undefined.
* 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)
