serialization, demo.cpp, error: undefined reference to ...
by Jan Martin Krämer 19 Oct '05

19 Oct '05

Hi, i couldn't fix the problems I had, trying to use serialization in my own code, so I decided to try and compile the demo.cpp file from the tutorial. If i just compile the file it's ok, but if i choose "build project" to create an executable, it fails with a lot of "undefined reference to ...". The specific error messages are in the attachement. I'm using kdevelop with ubuntu (breezy badger) and gcc 4.0.1. I've tried both the boost libraries that come with ubuntu (1.32.0+1.33.0-cvs) and to download and build them manually (boost_1_33_0). I'm not really a c++ guru and i just don't have a clue what I should do. Neither the documentation for the serialization library, nor google were of any help to me. It's probably just a misconfiguration on my part, but I don't know where to look or what to do. I hope you can help, if you need more information I'd be happy to provide it. Jan M.

[TR1 Review] TR1 Formal Review Beginning
by Beman Dawes 19 Oct '05

19 Oct '05

The formal review of the Boost TR1 Library by John Maddock begins today, Saturday, September 24th, and runs through Wednesday, October 5th. The TR1 library provides an implementation of the C++ Technical Report on Standard Library Extensions. This library does not itself implement the TR1 components, rather it's a thin wrapper that will include your standard library's TR1 implementation (if it has one), otherwise it will include the Boost Library equivalents, and import them into namespace std::tr1. Functionality supported includes: * Reference Wrappers * Smart Pointers * Class template result_of. * Function template mem_fn. * Function Object Binders. * Polymorphic function wrappers. * Type Traits. * Random Number Generators and Distributions. * Tuples. * Tuple Interface to std::pair. * Fixed Size Array. * Hash Function Objects. * Regular Expressions. * Complex Number Algorithm Overloads. * Complex Number Additional Algorithms. Functionality in TR1 but not yet available: * Mathematical Special Functions. * Unordered Associative Set (Hash Table). * Unordered Associative Map (Hash Table). * C99 C language additions. Additional information including online documentation is available at http://freespace.virgin.net/boost.regex/tr1/index.html The complete TR1 lib source and docs can be downloaded from http://freespace.virgin.net/boost.regex/tr1/tr1-20050816.zip Please help Boost by posting your formal review of this library. Your comments may be brief or lengthy, but basically the Review Manager needs your evaluation of the library. If you identify problems along the way, please note if they are minor, serious, or showstoppers. Here are some questions you might want to answer in your review: * What is your evaluation of the design? * What is your evaluation of the implementation? * What is your evaluation of the documentation? * What is your evaluation of the potential usefulness of the library? * Did you try to use the library? With what compiler? Did you have any problems? * How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? * Are you knowledgeable about the problem domain? And finally, every review should answer this question: * Do you think the library should be accepted as a Boost library? Be sure to say this explicitly so that your other comments don't obscure your overall opinion. --Beman Dawes, Review Manager

However, the solution for this is: Thanks for the suggestion Reece. I thrashed about some this morning turning on extensions. I'm now able to reproduce the problem that Markus Sch?pflin found: Markus Sch?pflin wrote: > For the next test, I changed struct test_values (in binary_int_test.cpp) to > the following: > > struct test_values { > uint64_t hex_value; > uint64_t bin_value; > }; > > This additionally needs #include <boost/cstdint.hpp>. > > When compiling and running this (on both 32 bit and 64 bit systems), I got > the following error: > > At test_array index 40 8a6c4e20 != ffffffff8a6c4e20 > assertion "test_array[i].hex_value == test_array[i].bin_value" failed: file > "../binary_int_test.cpp", line 118 And I found that...

I'm using the Microsoft 32-bit Compiler, Version 13.00.9466, and I'm running into two different problems with 64 bit values: 1. So far I've been unable to make Marcus's problem go away. With 32-bit values I was able to fix this up by forcing the underlying type that I write to my enums. When I try this same fix in 64-bits nothing gets better. 2. The worse problem is that binary value values larger than 32 bits (8 nibbles) get their upper nibbles truncated. After a couple of tests it appears that, for this compiler, the largest supported enum value must fit in 32 bits. If that's correct, then my enum based calculations run out of steam on this compiler at 32 bits. Hmmph. Matt Calabrese's macro-based approach is looking more appealing, at least as far as 64-bit support goes. Scott Schurr

[testing] Refactoring serialization tests, and possibly others.
by Rene Rivera 19 Oct '05

19 Oct '05

After having run two cycles of tests for Boost with the mingw-3_4_2-stlport-5_0 configuration and having it take more than 14 hours on a 2.2Ghz+1GB machine, most of that in the Boost.Serialization library[*]. And reading some of the recent discussion about the desire to expand testing to include cross-version compatibility and cross-compiler compatibility, and hence having the number of tests multiply possibly exponentially. I am seriously concerned that we are going in the wrong direction when it comes to structuring tests. From looking at the tests for serialization I think we are over-testing, and we are past the point of exhausting testing resources. Currently this library takes the approach of carpet bombing the testing space. The current tests follow this overall structure: [feature tests] x [archive types] x [char/wchar] x [DLL/not-DLL] Obviously this will never scale. My first observation is that it doesn't seem that those axis look like independent features to me. That is, for example, the char/wchar functionality doesn't depend on the feature getting tested, or at least it shouldn't. And I can't imagine the library is structure internally in that way. To me it doesn't make sense to test "array" saving with each of the 3 archive types since the code for serialization of the "array" is the same in all situations. Hence it would makes more sense to me to structure the tests as: [feature test] x [xml archive type] x [char] x [not-DLL] [text archive tests] x [char] x [non-DLL] [binary archive tests] x [non-DLL] [wchar tests] x [non-DLL] [DLL tests] Basically it's structured to test specific aspects of the library not to test each aspect against each other aspect. Some benefits as I see them: * Reduced number of tests means faster turn around on testing. * It's much easier to add tests for other aspects as one only has to concentrate on a few tests instead of many likely unrelated aspects. * The tests can be expanded to test the aspects more critically. For example the DLL tests can be very specific as to what aspect of DLL vs non-DLL they test. * It is easier to tell what parts of the library are breaking when the tests are specific. [*] That's just a CPU time observation, not to mention that it takes 2.15GB of disk space out of a total of 5.09GB. And it's only one compiler variation. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - Grafik/jabber.org

asio networking proposal 0.3.4
by Christopher Kohlhoff 18 Oct '05

18 Oct '05

Hello all, I have just released asio 0.3.4. You can download it, or view the documentation online, at http://asio.sourceforge.net. The major changes in this version include support for scatter-gather operations, an initial SSL implementation, and documentation improvements including an HTTP 1.0 server example. Code that uses asio will need to be updated. It is my feeling that there are no more major interface changes to be made, and my next goal is to convert asio into "Boost format" in preparation for a submission. Feedback is appreciated. In detail, the changes since asio 0.3.3 include: - Added support for scatter-gather on all read and write operations. These operations now take a list of one or more "buffers" for the operation. These buffers may be created to represent raw memory, POD arrays, boost::array or std::vector. This change breaks existing code, which needs to be fixed as follows. Where one used to write: sock.read(data, length); one now needs to write: sock.read(asio::buffers(data, length)); Similar changes are needed on all read, write, send and receive operations, both synchronous and asynchronous. - Added initial SSL support using OpenSSL. This takes the form of a template, called asio::ssl::stream, which can be used with any class which supports the Sync_*_Stream and Async_*_Stream concepts, e.g.: typedef asio::ssl::stream<asio::stream_socket> my_ssl_socket; Please note that for now this only works when used with single-threaded demuxers. A big thanks to Indrek Juhani of Voipster for developing the core implementation, and to Dirk Griffioen for organising this contribution. - Exceptions in handlers are no longer suppressed using catch (...). Instead they are now allowed to propagate out of the basic_demuxer::run function so they may be caught by application code. After an exception is caught, basic_demuxer::run may be called again immediately to continue processing. - Replaced the basic_demuxer::work_started/work_finished classes with an RAII class called basic_demuxer::work. - Added iostream output operators for ipv4::address, ipv4::tcp::endpoint and ipv4::udp::endpoint. - Added an HTTP 1.0 server example. - Added a kqueue reactor implementation for Mac OS X. Thanks to Stefan Arentz for providing the initial implementation. - Improved error handling in the epoll_reactor. - TSS slot usage has been minimised to use one slot for all demuxers of a given type, rather than one slot per demuxer object. - The calls to WSAStartup and WSACleanup have been made safer with respect to global demuxer objects. - Automaticaly link in ws2_32.lib when using asio on Win32 with Visual C++ or Borland C++. - Added back missing implementation of get_remote_endpoint. - Visual C++ 6 and gcc 2.95.x are not supported in this version, due to lack of testing resources. - Many documentation improvements. Note that I chose not to rename the send/receive family of functions to write and read, as had been discussed. After further thought I came to the conclusion that functions should only have the same name if they provide the same semantics. I think it's fair to say that read and write are the ideal names for the stream concepts' operations. However stream_socket's send and receive functions take additional parameters (flags) that can significantly alter the semantics (e.g. peek). A similar thing applies to not renaming datagram_socket's send/send_to/receive/receive_from functions, which are datagram-oriented, as opposed to the stream concepts' read and write which are (obviously) stream-oriented. Cheers, Chris
