This is not necessary - the binary is not used. The interface needs the 
SCIP library.

You mean that upon asking, you specify this path?

Can you please send me the output when you run "matlabSCIPInterace" (not 
via the list).

Does the compilation output warnings?

Except that something went wrong earlier, it could be the MinGW compiler 
is not set up correctly. Can you check whether the example from

works?
