I'm getting the same issue as PreciousPika: src/core/frame-interface.h references std::uint8_t but the header that type resides with (cstdint) has not been included.

I experimented with changing pkgver to the latest beta release (2.56.3) and, after fixing the sha256sum, that version built successfully so I don't think there's any need to take this upstream.

Adding #include <cstdint> to five different header files fixes the build for the current version. Best thing would probably just be to add a patch file that does exactly that until the next version is out of beta. Here's the patch file I used:

I'm having issues trying to install a package with this package as a dependency."librealsense" consistently fails to build, citing that CMake removed older version compatibility. It does give an option to append to override this check, but starting the install from yay does not allow you to override the compatibility check as far as I can tell. I'm not extremely experienced with Linux, but am very grateful for any advice or suggestions anyone has. Here's the exact error: In file included from /home/pika/.cache/yay/librealsense/src/librealsense-2.55.1/src/core/frame-holder.h:5, from /home/pika/.cache/yay/librealsense/src/librealsense-2.55.1/src/core/matcher-factory.cpp:5: /home/pika/.cache/yay/librealsense/src/librealsense-2.55.1/src/core/frame-interface.h:27:19: error: ‘uint8_t’ does not name a type 27 | virtual const uint8_t * get_frame_data() const = 0; | ^~~ /home/pika/.cache/yay/librealsense/src/librealsense-2.55.1/src/core/frame-interface.h:6:1: note: ‘uint8_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ 5 | #include <librealsense2/h/rs_frame.h> +++ |+#include <cstdint> 6 | #include <memory> make[2]: *** [CMakeFiles/realsense2.dir/build.make:79: CMakeFiles/realsense2.dir/src/core/matcher-factory.cpp.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:1023: CMakeFiles/realsense2.dir/all] Error 2 make: *** [Makefile:136: all] Error 2 ==> ERROR: A failure occurred in build().

ma work if you have compilation errors

Getting following error currently trying to compile with cmake 4.0:

==> Starting build()...
CMake Error at CMakeLists.txt:3 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

Adding -DCMAKE_POLICY_VERSION_MINIMUM=3.5 does work

I'm unsure if this qualifies as a build issue but I thought I should report it anyway. At the very least maybe others who experience the same thing will find this comment helpful. If you attempt to build this package with your C/C++ compiler set to Clang and without extra/openmp installed the build will fail with the following error message, even though extra/openmp is not a formal dependency:

CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:233 (message):
  Could NOT find OpenMP_C (missing: OpenMP_C_FLAGS OpenMP_C_LIB_NAMES)
Call Stack (most recent call first):
  /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:603 (_FPHSA_FAILURE_MESSAGE)
  /usr/share/cmake/Modules/FindOpenMP.cmake:616 (find_package_handle_standard_args)
  CMake/unix_config.cmake:38 (find_package)
  CMakeLists.txt:42 (os_set_flags)

Additionally extra/openmp must remain installed in order for the library to be used. This occurs because, unlike GCC, the base Clang package does not include the associated OpenMP implementation. Properly fixing this within the Arch dependency system would require adding a new "Provides: openmp" value to both extra/openmp and core/gcc which this package could then depend upon.

I had the same problem as acmiyaguchi when building monado. Their solution worked. Can this be patched?

@buresu the 'git' package is missing from makedepends. Package does not build without it:

CMake Error at /usr/share/cmake/Modules/ExternalProject/shared_internal_commands.cmake:951 (message):
  error: could not find git for clone of nlohmann_json

FYI 2.53.1 is the last version that supports the following cameras: R300, T265, T261, L515.

Hi, git is still needed to clone libcurl:

==> ERROR: A failure occurred in build().

Also, please remove the leading v in pkgver. And glu should be added as a dependency.
