Hi folks,

Good day to you!
I got this error "warning: 'bind1st<std::__1::multiplies<double>, int>' is deprecated [-Wdeprecated-declarations]" during compiling. I didn't get the expected results as I wish.

The code is very simple like below.

effectiveGreen = 94;
signalPlan.Clear();
signalPlan.Reserve(split.size());
transform(split.begin(), split.end(), signalPlan.begin(), bind1st(multiplies<double>(),double(effectiveGreen)));

The two vector are all Vector<double>. I didn't get correct results in "signalPlan".

Many thanks. I want all elements in "split" to be multiply "effectiveGreen" and stored in "signalPlan" in the same order.

Appreciate your help.

Best Regards
David

P.S.: Not sure what version of TheIDE you are using and when that feature was added, but it has now a nice function just for this case: You can directly google error message (right click it).
