NumericalMinimization.C crashes in 6.18

Hello,
When I try to run NumericalMinimization.C using

>root NumericalMinimization.C

I get the error:

Error in <HandleInterpreterException>: Trying to dereference null pointer or trying to call routine taking non-null arguments.

Execution of your code was aborted.

In file included from input_line_9:1:

tmp/NumericalMinimization.C:55:4: warning: null passed to a callee that requires a non-null argument [-Wnonnull]

minimum->SetMaxFunctionCalls(1000000); // for Minuit/Minuit2
^~~~~~~

I am running this on a Mac OS 10.14.5.

Any ideas?

Thanks,
Wolfgang

Try to use e.g.: minName = "Minuit"

It seems that your ROOT binaries are cut down and are missing “Minuit2”.
Try: root-config --features

Yes, indeed minuit2 was missing. Works now. Thanks for the info.
