#678 Similar error but i got it from building openrave

any reason it gives undefined reference to symbol '_ZN5boost6system15system_categoryEv'?

I have managed to solve this Issue during the make however similar error show up when i try this openrave.py --example hanoi

i checked '#define BOOST_SYSTEM_NO_DEPRECATED' in the boost_assertion_failed file.**

and this is ldd /usr/local/lib/python2.7/site-packages/openravepy/_openravepy_0_62/openravepy_int.so what could be causing this..?

[cielavenir]

is /usr/local/lib/libboost_python.so.1.58.0 py2 or py3?

maybe ldd /usr/local/lib/libboost_python.so.1.58.0

[benthebear93]

@cielavenir

ldd /usr/local/lib/libboost_python.so.1.58.0 linux-vdso.so.1 (0x00007fff9856a000) libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007fa3d9086000) libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007fa3d8e6e000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fa3d8c4f000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fa3d885e000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fa3d84c0000) /lib64/ld-linux-x86-64.so.2 (0x00007fa3d9658000)

those it suppose to have python2? i have ROS which run by python2 and also anaconda(python2, python3) i did all the installation related with openrave with python2 env in anaconda. maybe mixed python3 and python2 causing the problem?

[cielavenir]

umm nm -D /usr/local/lib/libboost_python.so.1.58.0|grep init_module|c++filt

let's see if it shows PyModuleDef& or const char *

[benthebear93]

@cielavenir it shows 0000000000031cf0 T boost::python::detail::init_module(PyModuleDef&, void (*)())

[cielavenir]

So /usr/local/lib/libboost_python.so.1.58.0 is python3 version!

Currently openrave assumes python2. You need to locate python2 version of libboost_python.so.

[benthebear93]

Im not sure how to change to python2. I will try to figure out!

[dal88236]

Hi @benthebear93 did you solve this issue?

[benthebear93]

@dal88236

I was not able to solve the issue. I only need to install openrave for ROS IKfast plugin, so i just used different computure which didn't have anaconda installed.

[cielavenir]

I just remember that Ubuntu 18.04 requires pybind11 build
