Thank you for your email, Johan. I resolved the issue, but the solution was different than the one you pointed out. It seems there is a bug in boost_1_33_1/libs/graph/src/Makefile.

I have a problem with the Boost Graph Library: I'm unable to link with the read_graphviz function. I'm using Boost v. 1.33.1 on Fedora Core 3, Linux 2.6.10, gcc 3.4.4. I try to compile the example boost_1_33_1/libs/graph/example/graphviz.cpp.

- Get the BGL sources - Build the libbgl-viz.a library (follow the instruction here:

http://www.cs.brown.edu/~jwicks/boost/libs/graph/doc/read-graphviz.html)

- Compile with this library (g++ your_source.cpp -Lpath/to/your/library -lbgl-viz)

Yes, I did all this: got newest Boost, compiled the non-header files of BGL and linked graphviz.cpp with the bgl-viz library. I followed the instructions at: http://www.boost.org/libs/graph/doc/read_graphviz.html I built the bgl-viz lib in two ways: 1. went to boost_1_33_1/libs/graph/src and typed: make 2. went to boost_1_33_1/libs/graph/build and typed: bjam "-sTOOLS=gcc" When trying to link with the bgl-viz lib, I got the same error: undefined reference to `boost::detail::graph::read_graphviz(std::basic_istream&, boost::detail::graph::mutate_graph&)' After some more work I realized that file boost_1_33_1/libs/graph/src/read_graphviz_spirit.cpp is missing at boost_1_33_1/libs/graph/src/Makefile:35. After I added it and recompiled the bgl-viz library, the example worked fine. Best, Irek
