1 # VxWorks Munching Feature
2 # When compiling C++ sources on VxWorks in kernel mode, all .o files have to
3 # be processed by the so-called 'munch' script which will generate
4 # additional code for static c'tors and d'tors. The resulting .c file has to
5 # be compiled in turn and linked to the executable.
6 # This can only been done when linking applications, since the munch script
7 # generates a .c file containing static symbols: linking a lib that was
8 # already munched to a munched application would lead to duplicate symbols!
