undefined symbol: _ZN5boost13thread_detail20rollback_once_regionERNS_9once_flagE

Hello,

I'm using ubuntu 16.04, gcc 5.4, and libboost1.58-dev:amd64. I followed this link to modify the Makefile in custom_ops folder. And I got the undefined symbol error as below. I don't know if my boost version is not correct? Or there could be some other reasons? I have confirmed that my boost libraries are installed in "/usr/lib/x86_64-linux-gnu". And boost header files are in "/usr/include/boost" (of course in my Makefile, BOOST_INC_DIR := $/usr/include, as in the aforementioned issue post). Thanks!

Does your boost installation have the boost.thread library compiled? Boost is largely include-only library but certain parts of it (like threads) needs to be specifically compiled. I would suggest trying to compile it from source with Threads turned on, and linking against that instead.

Build instructions are here, look for --with-libraries.

Thanks! I solved my problem. Some parts were not properly linked.

How do you solve this error? I had the same problem.
