Hi all
I'm trying to add doxygen-generated comments to my Python module build via SWIG using https://github.com/m7thon/doxy2swig. This means I need to run doxygen first, then run doxy2swig, and only then run swig. However, I'm getting reports that parallel builds are failing (sometimes). My strategy is based on CMake advice and some blogs (e.g. at https://samthursfield.wordpress.com/2015/11/21/cmake-dependencies-between-ta rgets-and-files-and-custom-commands/ ) and relies on creating custom commands to generate the files and custom targets to be able to specify dependencies on those generated files. Somewhat simplified code is below (original is at https://github.com/UCL/STIR/pull/280) # command that runs doxygen add_custom_command( OUTPUT doxygen.stamp DEPENDS ${doxyfile} COMMAND ${DOXYGEN_EXECUTABLE} ${doxyfile} COMMAND cmake -E touch doxygen.stamp .) # corresponding target add_custom_target( doc ALL DEPENDS doxygen.stamp) # command that runs doxy2swig add_custom_command( OUTPUT STIR_DOXY2SWIG.i DEPENDS doc COMMAND ${PYTHON_EXECUTABLE} doxy2swig.py -c index.xml STIR_DOXY2SWIG.i ) # corresponding target add_custom_target(doxy2swig DEPENDS STIR_DOXY2SWIG.i) # now add that target to the SIWG module add_dependencies(${SWIG_MODULE_stir_REAL_NAME} doxy2swig) Any suggestions on what I'm doing wrong? Many thanks! Kris PS: I note that FindDoxygen's doxygen_add_docs merges the add_custom_command and target into one add_custom_target, see https://github.com/Kitware/CMake/blob/a44191abc489373d295ecaeb5c2eb1573c876a 1a/Modules/FindDoxygen.cmake#L1104 I thought that couldn't be done but I guess I was wrong. PS: I also note that doxygen_add_docs doesn't create a doxygen.stamp file to prevent re-runs though, is that not needed then?
