Invoking "make -j8 -l8" failed for rgbdslam_v2 about rgbdslam_v2 HOT 3 OPEN

That is weird. The only error source I can make out is misc.cpp, line 763. Since this didn't change recently, I have no idea what causes this.

Maybe the rest of the error message would help. Please try running catkin_make -j1 for readability and to exclude the chance of memory exhaustion.

I assume you are working on an x86_64 architecture (see uname -m)?

Thanks for the reply. I get the output attached when running catkin_make -j1. It is similar to the previous output but has the whole error. I'm on x86_64. Thank you

Ok, the error is buried deeply:

/home/ap/catkin_ws/src/rgbdslam_v2/src/misc.cpp:804:25: error: ‘int round(float)’ conflicts with a previous declaration
/usr/include/c++/6/cmath:1708:3: note: previous declaration ‘constexpr float std::round(float)’

My guess is that, on your system, one of rgbdslam's dependencies includes the namespace "std" in a header file.

Probably the best solution is to explicitly scope the 4 calls of round in misc.cpp to the global scope, by replacing round(...) with ::round(...). Or rename the function to "round_float_to_int".
