Hi,

Now i want to use IloOplCplexBasis class to get and set basis .
However, when i add

IloOplCplexBasis::getBasis(cplex)

It shows the warning that :

error C2352: 'IloOplCplexBasis::getBasis' : illegal call of non-static member function
C:\ILOG\CPLEX_Studio_AcademicResearch122\opl\include\ilopl/ilooplmodel.h(546) : see declaration of 'IloOplCplexBasis::getBasis'

How to solve this problem?
Thanks.

Thanks.

Did you read the error message? It is clearly telling what you are doing wrong:
IloOplCplexBasis::getBasis() is not a static method of class IloOplCplexBasis. So you need an instance of this class to invoke this method.
In particular, you cannot invoke it with '::' notation (unless you are inside a subclass) but need to invoke it like 'basis->getBasis()' or 'basis.getBasis()', provided that 'basis' is either a pointer or a reference to an instance of IloOplCplexBasis.
How to obtain such a pointer or instance I don't know. I guess the people on the OPL Forum will be able to help you.
