Re: [ECOS] Using C++ operator new and delete

[David Luca <davidluca3000 at yahoo dot com>]

Yes, you are right, I was using gcc and not cpp
compiler. However, now I renamed hello.c to hello.cpp,
compiled with g++ and now I have a lot of errors...I
used -mhard-float, then remove it, used -mfpu=fpa,
fpe, none worked.
Thank you for your patience. I am new using gnu
toolchain, but I learn :). Here is the output:
