# 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!
