To use the MovingRegion3Algebra, the Region2Algebra has to be activated, too. The use of the MovingRegion2Algebra together with the MovingRegion3Algebra/Region2Algebra is not possible! The MovingRegion3Algebra/Region2Algebra uses the GMP-library, so the following needs to be done: In the file makefile.optimizer the option -lgmpxx has to be added at line 67: -lgmpxx LD_GMP := -lgmpxx -lgmp or use the switch in the makefile.algebras file: ALGEBRA_DIRS += Region2 ALGEBRAS += Region2Algebra ALGEBRA_DEPS += gmpxx gmp ALGEBRA_DIRS += MovingRegion3 ALGEBRAS += MovingRegion3Algebra ALGEBRA_DEPS += gmpxx gmp
