This probably means that at some point after the installation of polymake, the C++ compiler was uninstalled which is quite strange. You can try to reinstall a g++ or gcc package depending on what operating system you are using. You can check whether you have a working compiler by running 'g++ --version' in a terminal.Code: Select all
polymake: ERROR: Shared module compilation failed; see the error log below make: g++: Command not found make: *** [/tmp/poly23874Taaaa0013.o] Error 127
If you have done that just retry the polymake commands.
Note that the included_polyhedra function would force the computation of an H-description for P2.
