tags 850481 + moreinfo thanks Hi Ghislain, I just did a review on your package and note that it does not build the second time. It looks like the following files have been added to d/clean: tests/pybind11_tests.cpython-35m-x86_64-linux-gnu.so pybind11.egg-info/PKG-INFO pybind11.egg-info/SOURCES.txt pybind11.egg-info/dependency_links.txt pybind11.egg-info/top_level.txt Please, see if this is what happens. cheers, Giovani
