I am trying to decipher my strace. My setup is Linux beaglebone
4.1.12-ti-r29 #1 SMP PREEMPT Mon Nov 9 22:46:19 UTC 2015 armv7l
GNU/Linux BeagleBoard.org Debian Image 2015-11-12. I am not sure on
how to interpet my findings. In particular of the files that are
missing is that because I need an update or do they arise out a make
file that simply is not working or incorrect. The CMake version that I
am using is 3.0.2. Thanks for replies in advance.
