From many days, I have observed that our build sometimes goes into recursive loops and does not get out of the loop for many hours/days. I found the reason for this problem. It is about the modification time of makefile & C/C++ files. I use tar.gz which preserve file modification times and transfer that tar.gz to other systems. If those systems have different timezone, it might happen that the makefile/c/c++ files are modified in the future. Since gmake considers file modification times when running makefile, it goes in recursive loop. Simple solution is to touch the makefile/c/c++ files with future modification time using touch command.
