Hi,
Please read the changelog! What used to be an enum value such as INT_VAR_NONE before 4.* is now a function that when called creates a branching description, that is INT_VAR_NONE(). Please check MPG.

The custom class looks as below: class Cbcl_Options : public Options{ protected: StringOption _branchval; ... public: Cbcl_Options(const char* e) : Options(e), ....{ .... _branching.add(INT_VAR_NONE, "input"); _branching.add(INT_VAR_MIN_MIN, "min"); ... branching(INT_VAR_DEGREE_MAX); .... _branchval.add(INT_VAL_MIN, "min"); ... add(_branchval); .... } ... } I have used the proper namespaces and header files, but when I compile the code it gave me the following errors: g++ -Wall -g -I/usr/local/include -c cbcl_options.cpp cbcl_options.cpp: In constructor 'Cbcl_Options::Cbcl_Options(const char*)': cbcl_options.cpp:75:40: error: invalid conversion from 'Gecode::IntVarBranch (*)()' to 'int' [-fpermissive] _branching.add(INT_VAR_NONE, "input"); ^ In file included from cbcl_options.cpp:7:0: /usr/local/include/gecode/driver.hh:195:12: error: initializing argument 1 of 'void Gecode::Driver::StringOption::add(int, const char*, const char*)' [-fpermissive] void add(int v, const char* o, const char* h = NULL); ^ I am using gecode-4.2.1, but the seems to work on gecode-3.7.1. Can you please help me in correcting those errors. Thanks tad.
