VEX_Sort not working in 16.0.736 (Solved)

[wandersonp 11]

Hey guys the original example from VEX_Sort is not working at least in my windows machine

I change the code



#include <UT/UT_DSOVersion.h>
#include <UT/UT_Array.h>
#include <UT/UT_Vector3.h>
#include <UT/UT_Vector4.h>
#include <UT/UT_Matrix3.h>
#include <UT/UT_Matrix4.h>
#include <UT/UT_Assert.h>
#include <VEX/VEX_VexOp.h>

    {
        if (*a < *b)
            return -1;
        if (*a > *b)
            return 1;
        return 0;
      //Direct access to pointer value is not working in compare operator
        //return *a > *b;
    }

    template <>
    int compareValues<const char *>(const char * const *a, const char * const *b)

        return strcmp(*a, *b);
    }

            return -1;
        if (a->length2() > b->length2())
            return 1;
        return 0;
