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