r47 | # 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! | ||||

# a shared build, every lib, plugin and executable is munched separately. | ||||
