Hello everyone, The following lines produce a segmentation fault when executed from a compiled program which has been linked with libNew.so TMapFile *mfile; mfile = TMapFile::Create("hsimple.map","RECREATE",100000,"Demo memory mapped file with histograms"); mfile->Print(); TH1F *hodo; hodo = new TH1F("hodo"," Donnees Hodo ",100,0,500); hodo->FillRandom("gaus",10000); mfile->Update(); Apparently the last line upsets the program. Does anyone know why? And I would also like to know why one needs the instruction: TROOT root(.....) in a program. Thanks a lot. Primrose.
