ROS package to interface with IIO devices.
Vendors libiio (userspace IIO library) as it is not available on openEuler.
%prep
%autosetup -n %{RosPkgName}-%{src_version} -a 1
%build
# Build vendored libiio 0.25 first (openEuler has no libiio package).
# Using 0.25 (last 0.x release) because adi-iio 1.0.1 uses the libiio 0.x API
# (iio_buffer_cancel/destroy, iio_channel_enable/disable single-arg,
# iio_device_create_buffer, iio_buffer_refill/first/step/push) which was
# removed/changed in libiio 1.0. libiio 1.0.0 was tried in rounds 1-2 and
# caused compilation failures due to API mismatch.
# Network backend disabled: it transitively pulls in libavahi/libxml2
# (DNS-SD discovery + XML backend). adi-iio only needs the local backend
# (iio_create_context_from_uri with "local:" URI) plus the libiio API,
# so WITH_NETWORK_BACKEND=OFF avoids the whole dependency chain.

%changelog
* Mon Sep 28 2026 ai-importer <ai-importer@openeuler.org> - 1.0.1-4
- Switch vendored libiio from 1.0.0 to 0.25: adi-iio 1.0.1 uses the libiio
0.x API (iio_buffer_cancel/destroy, single-arg iio_channel_enable/disable,
iio_device_create_buffer, iio_buffer_refill/first/step/push) which was
removed/changed in libiio 1.0, causing compilation failures in iio_buffer.cpp.
libiio 0.25 header (iio.h) is at source root, not include/iio/ subdirectory.
* Mon Sep 28 2026 ai-importer <ai-importer@openeuler.org> - 1.0.1-3
- Disable libiio network backend: it requires libavahi/libxml2/libzstd which are
not pulled in; local backend suffices for adi-iio's iio_create_context_from_uri
* Mon Sep 28 2026 ai-importer <ai-importer@openeuler.org> - 1.0.1-2
- Vendor libiio 1.0.0 (not available on openEuler)
- Remove libiio-dev BuildRequires/Requires, add Provides: libiio/libiio-devel
* Mon Sep 28 2026 ai-importer <ai-importer@openeuler.org> - 1.0.1-1
- Initial import (ROS batch)
