Hi, I built the whole project in CLion. The messages are shown below:

I cannot figure out why linking error happens since I have installed all dependencies on my computer (Ubuntu 18.04). Could someone know how to fix it?

AndreiBarsan commented 4 years ago

I upgraded some of the code to use more modern APIs. Can you try building again? What version of CMake do you have? I use 3.10.2 and I am able to build on Ubuntu 18.04.

Frozenheart1998 commented 4 years ago

Hi, my cmake version is also 3.10.2 on Ubuntu 18.04.

AndreiBarsan commented 4 years ago

Can you try building without CLion? Like cd ~/DynSLAM && mkdir build && cd build && cmake .. -DWHATEVER_OTHER_PATHS_YOU_NEED=bla && make?

And if you've already done this, can you try pulling and doing a clean build? (rm -rf build/ and repeat)

Frozenheart1998 commented 4 years ago

I used another computer which is Ubuntu 18.04 and cloned the whole project again. It worked. I think it is related to the version of other unknown APIs since I never changed the version of CMake. Much Appreciated!

AndreiBarsan commented 4 years ago

Oh that's awesome to hear! The linker errors did look odd. Glad you fixed it and please let me know if you have any other issues!
