Hi, I tried other programs: g++ -ftemplate-depth-30 -I /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/ bfs_cc.cpp Then the program (a.out) run more than 1 minutes and didn't stop. (I killed..) is it ok? other two program: dfs_cc.cpp dijkstra_cc.cpp similar but e.g. dfs.cpp bfs.cpp are ready, immeadiately finished. Other things: When I compiled g++ -ftemplate-depth-30 -I /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/ leda_graph_cc.cpp I got: In file included from leda_graph_cc.cpp:26: /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/leda_graph.hpp:33: LEDA/graph.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/leda_graph.hpp:34: LEDA/node_array.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/leda_graph.hpp:35: LEDA/node_map.h: No such file or directory Exit 1 When I compiled g++ -ftemplate-depth-30 -I /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/ stanford_graph_cc.cpp I got: In file included from stanford_graph_cc.cpp:27: /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:54: gb_graph.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:55: gb_io.h: No such file or di rectory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:56: gb_flip.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:57: gb_dijk.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:58: gb_basic.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:62: gb_books.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:63: gb_econ.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:64: gb_games.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:65: gb_gates.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:68: gb_lisa.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:69: gb_miles.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:70: gb_plane.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:71: gb_raman.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:72: gb_rand.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:73: gb_roget.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:74: gb_save.h: No such file or directory /net/cooler/vol/export/proteome/murvai/CC/BOOST/boost_1_26_0/boost/graph/stanford_graph.hpp:75: gb_words.h: No such file or directory Exit 1 Janos
