cast from pointer to smaller type 'int' loses information

[Waldstein Wang]

Hi all,

I try to test the cvrptw.cc under example folder.

While every thing seems OK for testing, there is an error as title when building by CMake

I searched from Google and someone says uintptr_t should be used to replace all int.

Is that the only method to resolve this error?

If so, it means I need to do replacing and rebuild all library, right?

Thx.
