Hi Petr, to come back to my first point: I am using 13.1 and have been trying to compile the version you use for 13.2 - no way. But, if I am downloading the version from factory, everything is fine (apart from the gzipped info files issue). The difference shows here: octave-3.8.2-suitesparse-4.4.patch If this one is applied, compilation on 13.1 works flawlessly, if not, compilation is terminating with error messages. Therefore I switched to the version from factory - just to explain. Take care Dieter Jurzitza
