Sorry Dave, not 100% sure what kind of test you are talking about. Something
like this?
----------
// func0.cpp
int func0(int) __attribute__((weak));
int func0(int arg) {
return arg + 1;
}
// main.cpp
int func0(int) __attribute__((weak));
int func0(int arg) {
return arg + 10;
}
int main(int argc, char * argv[]) {
return func0(argc);
}
----------
Thanks!
