[Program Options] Multi-char option alias
by Uli Köhler 18 Nov '08

18 Nov '08

Hi everyone, is there a way to declare an alias for an options with more than one character, for example: options_description desc("Allowed options") desc.addOptions() ("disable-header,dh", "Disable") ; I'm using Boost 1.37.0 on Linux x64 and when I try to run the program it displays: "-d [ --disable-header ] Disable" The character 'd' is otherwise used (and 'h' is also not available) Do you know how to tell program_options to use a multi-character alias? Thanks in advance

Two issues - An error I think due to some invalid pointer and another speed problem.
by Raj Prasan 18 Nov '08

this is my second post. first I had a problem of a crash during startup and later changed my entry point and solved it. I got help from this list. Thanks a lot for that again.. This time I need some ways to debug it. Or a direct solution if possible. Please help this n00b folks. Scenario.. A AutoCAD like program. OpengL based.. Windows XP SP2 Code : C++ Mixed (native + managed.NET) /w CLR VS 2008, no MFC My code is pretty complex with a lot of classes, STL lists, maps pointers of the same objects in lists in different places. Issue 1 Moreover after adding the serialization library, the compile time has heavily increased. And the full system slows down. When compiling the task manager shows around 500 mb usage for the compilation process. I had a really lot of warning generated.. I mean more than 300 maybe or more. So I just disabled them in the settings. Compile Time - 7 mins 44 secs Link Time - 1 min 30 secs Total - 9 mins 14 secs Code is hardly 6000 to 10000 lines.. Can anyone guide me or give me links to articles that can help me.. Issue 2 Later I had this SEHException.. then I had to add try catch and found it raised unregistered class exception, so I fixed it adding BOOST_CLASS_EXPORT() below each class declaration... I still had some problems of redefinition, so I simply removed serialization from some classes and fixed that. Later I got some void cast exception, I still commented some more serialization code. Now It runs fine and gets me an file when I serialize immediately after initialization. After that when I create some lines/circles etc, and then serialize It gives me another error...

Problem compiling with CodeGear Borland 2007
by Philip Ogunbona 18 Nov '08

18 Nov '08

Dear Boost users: I have been successful in using boost under gcc 4.3. (running Linux FC9). I wanted to try compiling under Windows environment - Borland C++ 2007. A simple program using "boost/numerics/ublas/vector.hpp" will not compile. I got errors like: [BCC32 Error] is_reference.hpp(46) E2135 Reference cannot be declared 'const' or 'volatile' etc. I have looked at the header file "is_reference.hpp" to see if I could make something out of the line 46. It turns to be a "workaround" for BORLAND compiler. There is a comment to the effect "theses are illegal specializations: cv-qualifies applied to references have no effect according to [8.3.2p1], C++ Builder requires them though it treats cv-qualified reference as distinct types ..." I would like to know if any has been successful in using Borland compiler with boost library based codes. Regards, Philip Ogunbona

thread linking strangeness
by James Sutherland 18 Nov '08

18 Nov '08

I am observing strange things while linking boost::thread on a linux system with gcc 3.4.6. If I link an app with -L[path to boost.thread] -lboost_thread-gcc34-mt then it links fine. If I link with [path to boost.thread]/libboost_thread-gcc34-mt-1_36.a then I get linker errors with unresolved externals to things like: pthread_mutexattr_init pthread_detach pthread_getspecific I suspect it has to do with dynamic vs. static libraries. I have two flavors built: libboost_thread-gcc34-mt-1_36.so.1.36.0 libboost_signals-gcc34-mt-1_36.a So I suspect that in the first case I am getting a dll while in the second case the static link fails for some reason. Any suggestions/ tips to get the static link to work?

Hi I'd like to ask how can I get my template classes to work with boost class versioning? Since BOOST_CLASS_VERSION does not work for template classes. thanks Al

[BGL] Edmund Karps works with long, but does not with doubles
by Matthias Teich 17 Nov '08

17 Nov '08

Hello, I have some problems with the max-flow algorithms in the boost graph library. The only algorithm that worked for me was edmund karps, but only when I use long or int values as edge capacities. Here is my graph: typedef adjacency_list<listS, vecS, bidirectionalS, Node, Edge> Graph; typedef graph_traits<Graph> Traits; typedef Traits::vertex_iterator vertex_iter; typedef graph_traits<Graph>::edge_iterator edge_iter; typedef property_map<Graph, default_color_type Node::*>::type ColorMap; typedef property_map<Graph, int Edge::*>::type CapacityMap; typedef property_map<Graph, Graph::edge_descriptor Edge::*>::type ReverseEdgeMap; typedef property_map<Graph, Graph::edge_descriptor Node::*>::type PredecessorMap; typedef property_map<Graph, CapacityMap::value_type Node::*>::type DistanceMap; typedef property_map<Graph, long Node::*>::type IndexMap; struct Edge { CapacityMap::value_type capacity; CapacityMap::value_type residual_capacity; Graph::edge_descriptor reverse; }; struct Node { Mesh::FaceHandle faceHandle; CapacityMap::value_type distance; long index; Traits::edge_descriptor predecessor; boost::default_color_type color; }; Before calling edmund karps I add an edge with zero capacity to each existing edge and set the reverse edges. It would be very nice if anyone could give me a hint why this does not work. The push relabel and the kolmogorov algorithm always return 0 as result :( Best Regards, Matthias -- View this message in context: http://www.nabble.com/-BGL--Edmund-Karps-works-with-long%2C-but-does-not-wi… Sent from the Boost - Users mailing list archive at Nabble.com.

MSVC++ linker asking for boost_regex even though not using it
by Sharad Mittal 17 Nov '08

17 Nov '08

I have been compiling my program with boost_thread, boost_date_time and boost_system on mingw till now. Now I am trying to compile the same program on VC++ (9.0) and it is asking for libboost_regex-vc90-mt-sgd-1_36.lib . Is that normal? I have not used boost::regex in my code at all. Thanks, Sharad

tokenizer and R package
by Vidhu Choudhary 17 Nov '08

17 Nov '08

Hi Thank you all . With your help now I could install boost on windows I making a R package which contains c src code which uses tokenizer.hpp I made the package and tried to install it in Linux. I could install the package by successfully making the .so file When I tried the same in windows it showed error : bed2vector.C:13:31: boost/tokenizer.hpp: No such file or directory. While making the .dll R is using gcc to compile the files. Some how the boost libraries were not linked to gcc. And I dont know how to do it in windows from command line. If anyone could suggest it will be a great help --Vidhu

I want to do some dispatching based on the fatc that my binary_expr tag is one of predefined proto tag or not. What kind of internal properties of proto tags can I try to use to perform this discrimination ? Thanks in advance

Some problems about GIL
by blp330 17 Nov '08

17 Nov '08

Hi, 1. Does any one know how to crop a image using GIL? 2. The IO extension seems not support to serialize a image binary data to memory, how to do that using GIL? (read png -> do some stuffs... -> write png to char* buffer not file.) 3. Is there any one good performance image comparison algorithm to compare two images by GIL? I am using ImageMagick to do that now. It try to compute Mean Absolute Error for two images, how this can be done by GIL? Thanks for your answer, I am try to adopt my old ImageMagick's code to GIL, I like elegant design of GIL but I am a newbie. Thanks for you patient to answer my questions. :) -- View this message in context: http://www.nabble.com/Some-problems-about-GIL-tp20526156p20526156.html Sent from the Boost - Users mailing list archive at Nabble.com.
