[boost-users][MPL] Where did eq, gt, lt, et al. go?
by Cromwell Enage 17 Sep '04

17 Sep '04

These metafunctions used to be defined in the same headers as equal_to, greater, less, etc., respectively. What functionality should I use to replace them for my sequence algorithms?

boost.graph, subgraph questioon
by Jeffrey Holle 17 Sep '04

17 Sep '04

I'm using boost 1.31.0. I've experienced and observed that other fokes found this problem with subgraphs and internal properties. Derived subgraphs only get internal properties produced by default construct. What I'd like to know is if adding an edge to a derived subgraph via: add_edge(vertex_descriptor u_local, vertex_descriptor v_local, const EdgeProperty& p, subgraph& g) will get the property sent to the ancestor graphs? Are there any other "bugs" associated with adding edges/vertices to a derived subgraph?

It seems that boost.random doesn't work under vc6.0?
by huangliang 17 Sep '04

17 Sep '04

When I tried to compile the random_demo.cpp using vc6.0 and stlport5.0, there were many errors and warnings. Does boost.random correctly work under vc6.0? I use boost1.31.0.

sort implementation based on swap
by Russell Mok 16 Sep '04

16 Sep '04

I know this is kinda off topic. I am trying to sort some objects which are expensive to copy. Does anyone know a sort implementation that uses neither copier nor assignment? The STLport version I have is using both. Worse, some routines are passing arguments as T instead of const T &. I did search boost and google but I couldn't find what I want. Thanks in advance.

Building boost graph library for Visual C++ 7.1
by Brian Parker 16 Sep '04

16 Sep '04

Hi, I have performed a fresh install of Boost 1.31.0 under Windows (Visual C++ 7.1) and everything built and installed OK except that the Boost Graph Library libraries needed for GraphViz interface (libbglvis.lib) were not built or installed. Does anyone have any suggestions for building this library? I am not familiar with the jam file format. Thanks, Brian Parker

Re: [Boost-users] Compiling for Solaris, gcc, and STLport
by Tim Clemons 15 Sep '04

I found that the following lines in my BOOST_USER_CONFIG allowed for wide character support: #define BOOST_COMPILER_CONFIG "boost/config/compiler/gcc.hpp" #define BOOST_STDLIB_CONFIG "boost/config/stdlib/stlport.hpp" #define BOOST_NO_STDC_NAMESPACE #define BOOST_PLATFORM_CONFIG "boost/config/platform/solaris.hpp" #define BOOST_NO_COMPILER_CONFIG #define BOOST_STRICT_CONFIG I'm not sure why I defined BOOST_NO_COMPILER_CONFIG, or if it was even necessary (it was getting pretty late into the night). I think defining BOOST_STRICT_CONFIG was what did it.
