When building the documentation, a lot of text is output, meaning that any warnings can be missed in all the text. Unfortunately, ninja merges both stderr and stdout of all tasks so one cannot just redirect stdout to a separate location as part of the build command to rectify that. Therefore, since we rarely care about the output of the doc builds, only output the stderr text and write the standard output text to a log file in the relevant build folder (i.e. build/doc/guides or build/doc/api)
Related to this, we can catch documentation bugs earlier by setting WARN_AS_ERRORS for doxygen, meaning the build will fail if any API documentation warnings as encountered. Rather than setting this globally, we can link it to the global build --werror setting. --- V2: added in patches to fix API doc issue, and enable WARN_AS_ERRORS Bruce Richardson (6): doc/api: hide verbose doxygen standard output doc/api: align output folder with sphinx guides doc/api: put output log file in build directory doc/guides: suppress printing out standard output ethdev: fix mis-named parameter doc/api: make doc warnings errors when werror option set buildtools/call-sphinx-build.py | 6 ++++-- doc/api/doxy-api.conf.in | 1 + doc/api/generate_doxygen.sh | 6 ++++-- doc/api/meson.build | 10 +++++++--- lib/librte_ethdev/rte_ethdev.h | 2 +- 5 files changed, 17 insertions(+), 8 deletions(-) -- 2.25.1
