Installation error of Rtabmap standalone on Ubuntu 16.04

[brunoeducsantos]

Hey,
After I add libfreekinect , I did make install of rtabmap dir and the following error comes out:
collect2: error: ld returned 1 exit status
app/src/CMakeFiles/rtabmap.dir/build.make:503: recipe for target '../bin/rtabmap' failed
make[2]: *** [../bin/rtabmap] Error 1
CMakeFiles/Makefile2:416: recipe for target 'app/src/CMakeFiles/rtabmap.dir/all' failed
make[1]: *** [app/src/CMakeFiles/rtabmap.dir/all] Error 2
Makefile:149: recipe for target 'all' failed

Any leads what maybe?

[matlabbe]

Can you show full output of cmake and make?

[matlabbe]

It seems that some rtabmap's dependencies were built from source too. The make errors are about OpenCV. Did you try to build against standard OpenCV binaries? These errors can also happen when rtabmap's cmake was done with an opencv version, then a new opencv version has been installed, then doing make in rtabmap again without flushing cmake cache. Try to delete everything in the build directory and redo a clean cmake/make.

[brunoeducsantos]

I delete build and cmake/make it again and I got the following make log :

What could be the issue?

Now I installed opencv again and I am getting the following error on rtabmap cmake:

You could do "make VERBOSE=1" to see to which opencv libraries it is trying to link. This can help to debug if rtabmap is building against headers in /usr/local/include but linking with libraries in /usr/lib instead of /usr/local/lib. You can also make sure that you have only one Opencv installed.

At this point, I would suggest to follow steps 0 and 2 of this page. This will install all dependencies as binaries before you try to make rtabmap from source. Make sure to uninstall all dependencies built from source to avoid some problems if you try this.

cheers,
Mathieu

I successfully install rtabmap. thank you Matt
