Hi, Below is the details of my problem: gcc version and system: g++ (Debian 4.3.1-9) 4.3.1 I tried to compile the graph example (boost/libs/graph/example/graph.cpp) using the following command: g++ -Wall -I /cs/phd/freiman/include/boost_1_36_0 graph.cpp -o graph and got the following message about deprecated headers: ---------------------------------------- OUTPUT ------------------------------------------------- In file included from /usr/include/c++/4.3/backward/hash_set:64, from /cs/phd/freiman/include/boost_1_36_0/boost/graph/adjacency_list.hpp:22, from graph.cpp:15: /usr/include/c++/4.3/backward/backward_warning.h:33:2: warning: #warning This file includes at least one deprecated or antiquated header which may be removed without further notice at a future date.

When I tried to compile the kolmogorov max-flow example (boost/libs/graph/example/kolmogorov-eg.cpp) using the following command: g++ -Wall -I /cs/phd/freiman/include/boost_1_36_0 kolmogorov-eg.cpp -o kolmogorov-eg I got the following: -------------------------------------- OUTPUT ------------------------------------------------------ In file included from /usr/include/c++/4.3/backward/hash_set:64, from /cs/phd/freiman/include/boost_1_36_0/boost/graph/adjacency_list.hpp:22, from kolmogorov-eg.cpp:36: /usr/include/c++/4.3/backward/backward_warning.h:33:2: warning: #warning This file includes at least one deprecated or antiquated header which may be removed without further notice at a future date.

When I tried to run this example using the following command: kolmogorov-eg < max_flow.dat I got a segmentation fault: I tried to understand where the seg. fault came from using valgrind and it runs without seg. fault but with many "invalid read" errors, that seems to come from the file read_dimacs.hpp, line 118 Using the same code with WinXP and visual studio 2003, yields no problems. Any idea? Thanks, Moti

I'm a newbie to boost and have a storng interest in the graph algorithms

boost.

I tried to run both kolmogorov and edmund-karp examples and got many

warnings due to deprecated conversions in the read_dimacs function When I tried to run these examples I got segmentation faults. Other simple program (from boost homepage) that I tried to compile and run, run well. Is there any known issue about using boost with gcc 4 and later?

You need to be more specific about the errors system that you're building for and the errors that you're getting. Which version of Boost? Which compiler (very specifically)? What are the warnings? Can you tell what's causing the error?
