Reproducible: Always
have you actually checked to see if it works ?
python print(42) works. Pretty-printing std::vector works.
does libpython3.5 show up in `ldd /usr/bin/gdb` ?
Not exactly. libpython3.5m does. Pretty-printing python objects also works.
done now, thanks ! https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=8dc799ef5db54811778b38948b537dfa2342643d
