RE: [Boost-Users] [date_time] library binaries for VC7.1? && Comm on lib placement
by Administrator 18 Aug '03

18 Aug '03

Dan, The date_time.lib library is a static lib. The built date_time.dll actually has no exports in it, so for VC purposes is useless. I would say don't worry about it, and just use the static lib. On a side note, has anyone been working on placing built items into a common directory, say <boost_top_dir>/lib? If not, I have a patch that should help alot.

Type Traits
by Hossein Haeri 18 Aug '03

18 Aug '03

Hi friends, I'm looking for some stuff like the Loki::TypeTraits. I presume that there should be some similar ones in the boost repository. If I'm right, please tell me where they are. Thanks, --Hossein __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free, easy-to-use web site design software http://sitebuilder.yahoo.com

uClibc and Boost
by codeazure 18 Aug '03

18 Aug '03

Has anyone had success using Boost with the uClibc libraries? In particular, have you got Boost.Python to work? I am using the getting_started1.cpp example provided with Boost. I am using Boost 1.30.0, uClibc 0.9.20 and Python 2.2.3. Note that uClibc does not currently support a dlopen() called library calling a dlopen(). I have found that as long as the library is loaded with Python, I can get it to work. I am currently using the SSL version of the socket module, which is using SSL libraries linked against Python. I have tried 2 techniques so far, but both result in core dumps. 1. Compile Python against uClibc and force linking with libboost_python.so 2. Compile Pyhton against uClibc only. Build Boost application by linking against libboost_python.a so no external library is needed. It may be that the 2 libraries are simply not compatible at this stage. Does anyone have any ideas? David Abrahams has suggested low level debugging to work out what is causing the core dump, but if the problem lies deep within uClibc, then I have a problem. Regards, Jeff Gray

Variant library or alternative suggestion
by vivek_arora 17 Aug '03

Whats is the status of the variant library which was supposed to have been approved for inclusion? I was unable to compile the code submitted for review. Are there any alternative ways/libraries for representing typesafe unions ? thanks -Vivek Arora

newbie metaprogramming question
by Istvan Buki 17 Aug '03

17 Aug '03

Hello Boost experts, I'm starting learning about template metaprogramming and I discovered that Boost provide several libraries in that area. I tried to see if those libraries could be used for a piece of code I have in my mind but I have a hard time figuring out how to start with it. I don't know if it is because I try to apply metaprogramming techniques in a use case where they doesn't fit or because of my lack of experience with these tools. I'm posting my use case here to get some help and advice about it. In a library I provide two classes: 1) An abstract base class (let's call it Base) from which user will derive their own classes. 2) A manager class responsible for manipulating instances of classes derived from Base. The user, in his application, create an an arbitrary number of classes derived from Base. Let's call them A, B and C for example. He create a typelist containing all those classes and passes it as a parameter to the manager class: typedef boost::mpl::list< A, B, C > my_types ; typedef Manager< my_types> my_manager ; When an instance of my_manager is created I would like to automatically create one instance of each type present in the typelist and these instances should be stored in a container where I could access them later. Something like the following: template < class Typelist > class Manager { public: Manager( void ) ; // ..... private: std::vector< Base * > container_ ; // .... } ; template < class Typelist > Manager< Typelist >::Manager( void ) { // This is not C++, it is pseudo-code that shows what I would // like to achieve. FOR EACH Typelist item i DO Base *b = new Typelist[i] container_.push_back( b ) ; END } So, at compile-time, some code should be generated to do what I wrote in pseudo-code in the constructor of Manager. Does this make any sense ? And if it is, could someone help me transform transform the pseudo-code in the constructor of manager to real code ? Thanks for any help you could provide, Istvan

Errors building boost w/ VC++ 6.0 sp5

I downloaded boost_1_30_0.zip, unpacked the zip file, cd'ed into boost_1_30_0, and ran "bjam "-sTOOLS=msvc". Most of the library seemd to compile fine (Python was skipped since I didn't have it installed). Bjam failed to update 12 targets, skipped 12 targets (the same 12 that failed?), and updated 452 targets.

I download boost_1_19_0 and built it in .net, now I want to test the libraries is right or not, I try to build the hello module in the example, but fail, it saying that: c:\Program Files\Microsoft Visual Studio .NET\Vc7\include\cstdio (15): error C2059: syntax error : ':' any trick about it

The following bug exists also as sourceforge bug request: [ 778394 ] GraphViz Interface boost version is 1.30.0 Because Jeremy seems to be reactivated and the sourceforge tracker status is still 'open' a small reminder: For an adjacency list of the following form adjacency_list<listS, listS, undirectedS, PositionProperty> write_graphviz produces the following graph structure --- output begin --- graph G { graph [splines=false bgcolor=lightgrey] node [shape=circle color=red] edge [style=solid] 002F48A0[label ="", height="0.1", pos="540,250"]; 002F4978[label ="", height="0.1", pos="278,321"]; 002F4A50[label ="", height="0.1", pos="198,67"]; 002F4B28[label ="", height="0.1", pos="163,27"]; 002F4C00[label ="", height="0.1", pos="442,487"]; 002F4B28--002F4A50 ; 002F4A50--002F4978 ; 002F4978--002F4B28 ; 002F4B28--002F48A0 ; 002F48A0--002F4A50 ; 002F4978--002F48A0 ; 002F48A0--002F4C00 ; 002F4C00--002F4978 ; } --- output end --- This causes error messages from neato (GraphViz tool): --- error messages begin -- v:\my\delaunay\test\d1\output>neato -s72 -n2 -Tgif -o file.gif delaunay.dot Warning: delaunay.dot:5: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:6: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:7: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:8: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:9: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:10: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:10: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:11: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:11: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:12: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:12: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:13: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:13: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:14: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:14: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:15: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:15: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:16: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:16: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:17: ambiguous "002F" splits into two names: "002" and "F" Warning: delaunay.dot:17: ambiguous "002F" splits into two names: "002" and "F" Error: node 002 in graph G has no position as required by the -n flag v:\my\delaunay\test\d1\output> --- error messages end --- The reason can be found at: http://www.research.att.com/~erg/graphviz/info/lang.html "An ID is any string of alphabetic characters, underscores or digits, but not beginning with a digit; or a number; or any quoted string possibly containing escaped quotes." So, the hexadecimal number (mix of digits and characters) of the transfered pointer (list item) is the problem.I would suggest write_graph_viz quotes the node name or prefixes with a character or uses a decimal representation.
