RE: [ECOS] Dose eCos support C++ or only C?

["Dan Conti" <danc at iobjects dot com>]

eCos supports C++ just fine, but it expects your entry point (i.e.
cyg_user_start, or main) to be a C-style function, i.e. no name
mangling. Running your code through the C++ compiler wont generate the
proper symbol by default. You need to explicitly state that you want C
style naming for your routine:

extern "C" void cyg_user_start(void);

or

extern "C" int main( void );

Just toss that in your source file right in front of your
implementation.
