I can tell you that on a fedora/redhat box, you just include the headers and you are away. If you installed the development package group it will be there and you can build c++ programs and use boost out of the box. What distro are you using?

hello world in boost ?
by paul wisehart 10 Nov '04

10 Nov '04

Hi, I am able to compile the boost libaray on my linux machines. I am not able to use it. Is there a simple program I can try to compile to make sure I am doing things correctly. I'm sorry. its a shortcoming of mine, but I can't do _anything_ until I have a working stub. (or hello_world, or wahtever you want to call it.) I just need a simple example of how to compile a boost prohram from g++ . please help me :) -- paul \ / wisehart >/ <//////$> |\|\|\

write_graphviz: write out edges when vertex data is a boost::shared_ptr?
by Stephen torri 09 Nov '04

How does one write out the proper edge node names when the vertex data is a boost::shared_ptr? My graph is defined as: typedef property< vertex_index_t, uint32_t, property< vertex_name_t, boost::shared_ptr<Component> > > VertexProperty; typedef adjacency_list<setS, // OutEdgeList setS, // VertexList directedS, // Directed VertexProperty> // VertexProperties Graph_Type; The call in … [View More]

PropertyWriter problem - how to handle a boost::shared_ptr type
by Stephen torri 08 Nov '04

08 Nov '04

I have the following graph: typedef property< vertex_index_t, uint32_t, property< vertex_name_t, boost::shared_ptr<Component> > > VertexProperty; typedef adjacency_list<setS, // OutEdgeList setS, // VertexList directedS, // Directed VertexProperty> // VertexProperties Graph_Type; When I looked at the documentation I did not see an example which used a boost::shared_ptr to store information at the … [View More]vertex.

signals library with stlport
by tweety 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
