Hi, I am not sure whether this is a bug in dh-python or if something is wrong with my package (python-asdf). The package has an (almost) standard setup, so dh_build is not overridden.
However, when I try to package, some subdirectories are not copied; namely `asdf/external`: ----------------------------8<---------------------------------- dh_auto_build -O--buildsystem=pybuild I: pybuild base:217: /usr/bin/python3 setup.py build running build running build_py creating /build/python-asdf-2.4.2/.pybuild/cpython3_3.7_asdf/build/asdf [...] ----------------------------8<---------------------------------- The subdir `asdf/external` which is in the source is not created and not filled during this process. However, when I run `python3 setup.py build` or `pybuild --build` manually, everything is correct: ----------------------------8<---------------------------------- $ python3 setup.py build -vvv running build running build_py creating build creating build/lib creating build/lib/asdf copying asdf/yamlutil.py -> build/lib/asdf [...] creating build/lib/asdf/extern copying asdf/extern/RangeHTTPServer.py -> build/lib/asdf/extern copying asdf/extern/__init__.py -> build/lib/asdf/extern copying asdf/extern/atomicfile.py -> build/lib/asdf/extern copying asdf/extern/decorators.py -> build/lib/asdf/extern [...] ----------------------------8<---------------------------------- Is there any idea what happens here? Why does pybuild (or setup.py) behave differently when called from dh_python than directly? How can I ensure that all files are copied during dh_auto_build? Best regards Ole
