Hello Adrian If I look at the current boost1.67, I find this in the boost python package
https://packages.debian.org/sid/amd64/libboost-python1.67.0/filelist and https://packages.debian.org/sid/amd64/libboost-python1.67-dev/filelist We can find these /usr/lib/x86_64-linux-gnu/libboost_python3-py36.a /usr/lib/x86_64-linux-gnu/libboost_python3-py36.so but only for the python3.6 version and not for 2.7 and 3.7 previously we had for boost 1.62 https://packages.debian.org/sid/amd64/libboost-python1.62-dev/filelist all python version add these -pyXY.so files. Is it an intended change in the new boost_python package, or a mistake ? This logic -pyXY was coded in the pytango setup.py, in order to deal with boost_python. cheers Fred
