2022-11-24libcamera: tracing: fix header generation when built as subprojectBarnabás Pőcze
Building libcamera as a subproject is failing when tracepoints are enabled due to incorrectly managing the relative paths between the source and build directory while generating tracepoint headers. The previously used path = output.replace('include/', '', 1) logic is not sufficient to correctly determine the proper path when libcamera is built as a subproject, and does not correctly handle the relative paths, causing path to be processed as: 'subprojects/libcamera/include/libcamera/internal/tracepoints.h'.replace('include/', '', 1) which evaluates to 'subprojects/libcamera/libcamera/internal/tracepoints.h' so the tracepoints.h header file will try to include: #define TRACEPOINT_INCLUDE "subprojects/libcamera/libcamera/internal/tracepoints.h" which will fail. Fix it by using Python's pathlib to calculate the relative path of the output file with respect to the "include" directory of libcamera. This has been tested with Pipewire. For non-subproject builds it should generate the exact same path that was previously generated.

Other options are allowed, even if not recommended, such as storing both the raw image data and the Exif data in IFD0, as done by the TIFF/EP specification. libcamera-apps use pyexiv2 to produce DNG files, following the DNG recommendation, while applications based on picamera2 use PiDNG, which adopts the TIFF/EP structure. Why it does so is not currently clear (see https://github.com/schoolpost/PiDNG/issues/65 for discussions on this topic), but as files based on the DNG and TIFF/EP variants exist in the wild, both need to be supported by ctt.
