Hi Josh - you da man! This fixes the problem, and the 3.9 OOT runs now.
Of note for anyone else following along: the 2.4.3 tarball for pybind11 listed in the 3.9 OOT porting guide instructions does not create a make uninstall target. It does however produce an install manifest. I went through that and deleted what it installed before proceeding. Then sudo apt install pybind11-dev This installed 2.5.0 -- Tom, N5EG On Mon, May 10, 2021 at 4:01 AM Josh Morman <mor...@gmail.com> wrote: > Tom, > > It looks like the OOT might be using a different version of pybind11 than > the ppa version of gnuradio was built against.
