I have no way to test in anything else than Ubuntu 16.04. So, I honestly have no idea.

I've successfully compiled this package on Ubuntu 18.04 and ROS melodic using the following CMAKE flags:
cmake .. -DCMAKE_BUILD_TYPE=DEBUG -DCMAKE_C_FLAGS_DEBUG="-g -O0" -DCMAKE_CXX_FLAGS_DEBUG="-g -O0"
Using the -O3 optimization flag causes a segmentation fault.

@iaherzog OMG, thx! I tried on Ubuntu 18.04 many times, but all failed. Your codes can really work.

If you want to use those optimization flags that do work, you could figure out which ones the -O3 optimization flag turns on, and then turn them on/off individually to see which are possible in 18.04.

Could you try the following flags?

set(CMAKE_CXX_FLAGS "-O3 -march=native -mtune=intel -msse4.2 -mavx2 -mfma -flto -fopenmp -fPIC -Wno-d eprecated -Wenum-compare -Wno-ignored-attributes -std=c++17")

This works for me in Ubuntu 18.04 where with the previous set of flags, I'd encountered a segfault. The compilation takes some time, but GPD runs fast.
