/usr/bin/ld: cannot find -lboost_python-py36

system: Ubuntu16.04 virtualenv create the only python3.6 environment:

$ pip3 install -e $ROBOSCHOOL_PATH

    C++ dependencies for this project are:

    bullet
    tinyxml
    boost_python
    assimp
    Qt5

    If you see compilation error FIRST THING TO CHECK if pkg-config call was successful.
    Install dependencies that pkg-config cannot find.

I don't know what going on, i can test boost example under python3.6 environment. Can we due with this question together?

[huangjiancong1]

It seem that there have no libboost_python-py36 generated when i install Boost. But generated libboost_python-py35 under the python3.6 only virtual environment.

@huangjiancong1 : How do you solve your problem?

[id9502]

try to modify /robotschool/cpp-household/Makefile line:59: BOOST_PYTHON = -lboost_python$(BOOST_PYTHON3_POSTFIX) to BOOST_PYTHON = -lboost_python3$(BOOST_PYTHON3_POSTFIX), this may solve the error

[zanovis]

@id9502's fix partially worked.

I replaced BOOST_PYTHON3_POSTFIX in line:59 with "3" and it fixed the issue that /usr/bin/ld: cannot find -lboost_python36

This is probably not a sustainable fix, so if someone has a better suggestion please let us know.
