I suppose you have enabled -Wall in the CB project settings?

smallB:
Hi Neil, yes, I have it set. The output from a program (in cb in build log tab):


--- Code: ---int f()
{
}

int main()
{
f();
}
--- End code ---

is:

zabzonk:
If your code compiled with warnings,  but with zero errors, it is not by default re-built the next time you hit "run", so you won't see the warnings a second time. To see the warnings again, you need to explicitly rebuild.  The stuff in the build-log is from the last compilation.

smallB:
Neil, thanks, indeed rebuild does the trick.
