Here you promise to the compiler that there exists
somewhere the definition of a function named
'Table::v3_snap shot()'. Did you provide one?

'snapshot()' is a function. Why are you trying to assign
something to it?
}

snapshot = this->v3_snapshot(re alm);

return snapshot;
Why are you trying to return a type other than what

It probably means that you need to add tables.cpp to your project or
make file.
Good luck,

'snapshot()' is a function. Why are you trying to assign
something to it?
'snapshot' is also a local variable, hiding the name of the function
in which it's declared. Look at the first line inside the body of
this function.
int foo()
{
int foo = 42;
return foo;
}
int main()
{
return foo();
}
This practice is not recommended, but it's perfectly legal.

My mistake was to have the declarations done but to have the
implementations under under names. Kicked myself a bit when I saw that
I had forgotten to rename the fuctions after renaming the declarations.
Didn't help that the error message is a mouthful and that Intellisense
seemed to see things that were no longer there but untimately my fault. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |
