ublas compatible solvers (newbie question)

Hi all, I'm looking into using uBLAS for solving some big sparse systems, specifically with conjugate gradient family of solvers. Could anyone point me towards boost-compatible implementation of such solver ? thanks in advance

signals library with stlport
by tweety 08 Nov '04

08 Nov '04

how can i compile the signals library with stlport? i have tried setting STL_PORT_PATH and STL_PORT_VERION but when i run bjam -sTOOLS=vc-7.1-stlport it says it cannot find vc-7.1-stlport.jam (which is true, there's only jamfile and jamfile.v2 in signals/build) and if i just run bjam it gives me the native stl libraries (which, of couse, won't autolink with my program). can you help me? ---------------------------------- Peace and love, Tweety mitea(a)sympatico.ca - tweety_04_01(a)users.sourceforge.net YahooID: tweety_04_01

Re: boost graph library bugs
by Qiaofeng Yang 07 Nov '04

07 Nov '04

Hi, Below is a list of bugs (at least I think so) in boost graph library: 1. I used the functions illustrated in file "components_on_edgelist.cpp" on a adjacency_list graph instead of a edge_list graph. It gave the correct number of components in the graph, but when printing out each components, the nodes in some of the components were disconnected. Also, segmentation fault was flagged.(This happened when the graph had a lot of components.) 2. I ran the source code in file "subgraph.cpp" as it was, the output was different from the sample output given in the same file. The difference was: the subgraph had global edge index, but local vertex index. 3. When creating multiple subgraphs, code like below would give segmentation fault: " typedef property<vertex_name_t, string> VertexName; typedef property<vertex_index_t, int, VertexName> VertexProperty; typedef property<edge_index_t, int> EdgeProperty; typedef subgraph< adjacency_list<vecS, vecS, undirectedS, VertexProperty, EdgeProperty> > Graph; ... Graph G(N); //add edges to G //assign names to vertices in G ... Graph & G1 = G.creat_subgraph(); //add vertices to G1 //assign names to vertices in G1 ... " When using function put(PropertyTag, const subgraph& g, Key k_local, const Value& value) to assign names to the vertices of subgraph G1(it seems that the name of vertices in G is not automatically inherited by G1.), it gave segmentation fault. This problem would not happen if the number of subgraphs was few such as 2. I found the above problems when I tried to create subgraphs for each component in the graph when the number of components was large. Thanks for your time, Qiaofeng

problem with boost::thread libraries
by Vinodth Mohanam 06 Nov '04

06 Nov '04

Hi, I came across this problem in using the threads package. I used the following files: boost_thread-vc71-mt-gdp-1_31.lib boost_thread-vc71-mt-gdp-1_31.dll boost_thread-vc71-mt-p-1_31.lib boost_thread-vc71-mt-p-1_31.dll While trying out a simple example from the test folder: #include <boost/thread.hpp> #include <boost/thread/xtime.hpp> using namespace boost; ............ ............ ............ void HelloWorld() { } ............ ............ ............ // Test threads boost::thread thrd(&HelloWorld); thrd.join(); ............ ............ ............ The application gave the following link error: Abacus error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall boost::thread::thread(class boost::function0<void,class _STL::allocator<class boost::function_base> > const &)" (__imp_??0thread@boost@@QAE@ABV?$function0@XV?$allocator@Vfunction_base@ boost@@@_STL@@@1@@Z) referenced in function "public: unsigned int __thiscall mok3::Abacus::Application::init(void)" (?init@Application@Abacus@mok3@@QAEIXZ) The program works fine without any parameters to the constructor ( boost::thread thrd; ), but of course that's not useful. If it were a syntax error it should be at compile-time, but there is no problem during compilation. Also, if there is a patch for statically linking threads package, it would be appreciated if you could send it. I am compiling the libraries with the following settings: Boost_1_31_0> bjam -sTOOLS=vc7.1-stlport -sSTLPORT_PATH=... install Thanks, -Vino

write_graphviz with listS as vertex container
by Meredith L. Patterson 05 Nov '04

05 Nov '04

Hi all, I've been using the Boost Graph Library for a project that requires the use of the graphviz library, and have run into a quandary. For reasons that are a bit complicated to get into right now, my users need to be able to remove vertices from what are at times extremely large graphs (~75,000 vertices), so vecS is clearly the wrong type for runtime reasons. The problem comes with write_graphviz. As the documentation points out, the graph must have an internal vertex_index property map; listS doesn't have an inherent vertex_index the way vecS does, so I've defined vertex_index as a property (along with vertex_name); the code compiles and runs. However, in the DOT output, I get a vertex list that looks like: 0[label="foo"]; 1[label="bar"]; 2[label="baz"]; [....] and an edge list that looks like 0x8061d90->0x8061db8 [weight="5"]; 0x8061d90->0x8061c50 [weight="13"]; [....] Obviously, the edge list is using vertex descriptors (which in this case end up being the memory location of each vertex object), while the vertex list is using vertex indices (and a quick look at graphviz.hpp confirms this; starting from line 262, the function uses get(vertex_index, *i) to get vertex identifiers for the vertex list in the DOT file, and source(*ei, g) and target(*ei, g) to get source-vertex and target-vertex identifiers for the edge list. This isn't a big deal when the vertex list type is vecS, of course, because vertex-index is basically a pointer into the vector, but it doesn't work for listS, setS, et cetera. Any suggestions for how to resolve this contradiction? I suppose I could try overloading source() and target(), but if there's an easier way to do it, I'd rather go that route. :) Cheers, Meredith L. Patterson

(Has everyone in the US gone on holiday to avoid the election coverage?). Could the registration process at ublas-dev in yahoo groups be relaxed as there do appear to be measures to stop spambots autoregistering. ------------------------------ All, I have been waiting for acceptance into the uBLAS-dev group for approximately two months now. I have completely given up on lobbying for expiditing this process. I would love to have access to this group! I am deeply involved in projects using uBLAS.

RE:RE:Re:Re: i am stuck since a week here: need help:scoping error when trying to make boost work with luabind

thanks again brian.Like u said, i also thought about project settings and made sure I had set the various options and linker specifications correctly...well, i solved a lot of issues and i am down to 12 errors from initially 122. Which is quite a relief, but these last 12 are still an issue taking away a considerable time of mine. I am working on them right now but do let me know if you have any clue. They are mainly some issues with luabind and boost. I have just made #include references to luabind and boost. Havent included any .libs for them, so it would be great if you let me know if there are any specific .libs for the same that need to be added to the project settings. APart from that I have made sure that the various include and lib directory paths have been set correctly. I am attaching the error message below, thanks again in advance, regards, rohit Linking...

I would also suggest to you if you setup JUST VC projects for EVERYTHING and get everything to build properly in the MS tool (I am not sure if below is bjam or not) that will at least get you to something that works and it will be easier to take the bjam step from there.

boost function problem
by gast 128 04 Nov '04

Dear all, I am little bit tired, but probably people can help me and explain why this does not compile on VC++ 7.1: struct NCFoo { template <int i> void f(){} void g(){} }; void Bla { void (NCFoo::*pmf)() = &NCFoo::f<4>; boost::function<void (NCFoo*)> fc1 = &NCFoo::f<4>; //does not compile boost::function<void (NCFoo*)> fc2 = boost::bind(&NCFoo::f<4>, _1); //does not compile boost::function<void (NCFoo*)> fc3 = &NCFoo::g; } Probably it has to do with template argument matching, but can someone give a quick help?
