[hjjayakrishnan]

While executing build.sh, it started throwing up internal compiler errors.
My gcc version : gcc (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609
Ubuntu : 16.04
ROS: Kinetic

And these errors keep going and I have to forcefully stop it, because it froze up my PC. Any ideas why this is happening? Thanks

Hi, I managed to resolve the issue. It was a memory problem so I had two options in hand: either add more memory to swap space and then execute build.sh or remove the parallel make operation in the build file. The former alternative would help in faster compilation.
