Hi folks,

I would like to use link time wrapping so I tried linking a program using QCC with the following option 
              --wrap foo  

This does not work. How should I proceed to wrap functions in my program ?
Thanks in advance,

Wim

It's a linker option so you have to pass it through to the linker using 
-Wl, For example:

-Wl,--wrap,foo

Re: Link time wrapping using QCC

Thank for the reply.

Linking did continue  but resulted  in the  unresolved symbol

                          undefined reference to `__real_foo()'


I got ride of it using extern "C" linkage 

Do the wrapped functions alway require C linkage ?
