Hi Ovanes, I found the problem. The console_test_runner and my NetCtrld.dll used different boost_unit_test_framework-....dll's. So I had two different master test suites, one in each DLL. Now it seems to be working.

[program options] support for sections
by Ovanes Markarian 16 Jan '08

16 Jan '08

Hello! In my last project I remeber to see somewhere that boost::program_options library supports config files sections. But I can not find any hints to this feature in the current doc. Does anyone has an experience with sections in the config file? With Kind Regards, Ovanes

Hi Ovanes, this is, why I added 'printf("Initializing\n"); to init_unit_test() in my DLL. As this is indeed printed before the error message, I think that the lib is found and loaded. Furthermore, if the lib cannot be found, I get: C:\Projekte\Test\NetControl\bin>console_test_runner --test NetCtrl.dll Boost.Test framework internal error: unknown reason So it seems that the DLL is loaded and init_unit_test() is invoked, but the test cases are not registered ...

Applying Boost license to non boost projects
by Roshan Naik 16 Jan '08

16 Jan '08

I am interested in adopting the Boost Software license for an open source C++ library (Castor: http://www.mpprogramming.com/2.html) The Boost FAQ describes how to apply the license to Boost header files. It basically states that the foll. lines should be included: // Copyright Joe Coder 2004 - 2006. // Distributed under the Boost Software License, Version 1.0. // (See accompanying file LICENSE_1_0.txt or copy at // http://www.boost.org/LICENSE_1_0.txt) - Does this same guideline apply to non boost projects ? The need for stating Boost.org there might confuse some users of non boost prj to think that the library is supplied by Boost. - Do all header files in my prj (which is a pure header library) need to include this text at the top/somewhere in order to adopt the license. -Roshan

[iostreams and serialization] serialize via iostreams
by Pooyan McSporran 15 Jan '08

15 Jan '08

I'm trying to use a combination of the iostreams library and the serialization library in order to be able to serialise objects and send them over a socket. I've written a class called "SocketDevice" which implements a bidirectional iostreams instance, and I'm trying to use this with serialization, in particular the binary_oarchive and binary_iarchive archive models. The problem is that when I do this, the code ends up calling a copy constructor (which doesn't exist) on my SocketDevice class. However I don't want to implement a copy constructor for this class as it doesn't make sense (as it manages a socket and a buffer for that socket, etc). The interface of my SocketDevice class looks like this: class SocketDevice : public boost::iostreams::device<boost::iostreams::bidirectional> { public: typedef char char_type; SocketDevice (int sock); ~SocketDevice (); std::streamsize read (char *s, std::streamsize n); std::streamsize write (const char *s, std::streamsize n); private: const int sock; char *buffer; size_t bufferSize; }; and I'm trying to do the object sending/receiving via template methods, eg: template<class C> void sendObject (const C& data, int sock) { boost::iostreams::stream_buffer<SocketDevice> buf (sock); std::ostream s (&buf); boost::archive::binary_oarchive oa (s); oa << data; } The copy constructor appears to be synthesised when the 'buf' object is instantiated in the above template method. My guess is that I'm doing something wrong, but I can't see what. I've also tried splitting my SocketDevice class from a bidirectional one to a pair of input & output ones, but with the same result. I've also tried making sendObject() a normal (non-template) method, this makes no difference. I realise that there are issues with trying to combine socket communications with object serialisation, but I'm still curious as to why I have this copy constructor issue.

Boost.Test Framework to test a DLL
by Plonka Christian 15 Jan '08

15 Jan '08

Hi, I'm planning to change from CppUnit to Boost.Test for unit testing since it is now possible to integrate unit tests also in a DLL. Nevertheless I do encounter some problems here. The code is (I guess you'll recognize it): //---------------------------------------------------------------------- --- #define BOOST_TEST_DYN_LINK #include <boost/test/unit_test.hpp> using namespace boost::unit_test; BOOST_AUTO_TEST_CASE( test1 ) // void test1() { int i = 0; BOOST_CHECK_EQUAL( i, 2 ); } BOOST_AUTO_TEST_CASE( test2 ) { BOOST_CHECKPOINT("About to force division by zero!"); int i = 1, j = 0; i = i / j; } extern "C" { __declspec(dllexport) bool init_unit_test() { printf("Initializing\n"); framework::master_test_suite().p_name.value = "Test runner test"; // framework::master_test_suite().add( BOOST_TEST_CASE( &test1 ) ); return true; } } //---------------------------------------------------------------------- --- I the sample (test_runner_test.dll) it works fine but when I use it in my DLL I get: C:\Projekte\Test\NetControl\bin>console_test_runner --test NetCtrld.dll Initializing Test setup error: test tree is empty I also tried the commented version using master_test_suite().add() without any change.

MetaComm and Boost Consulting SVN daily snapshot services
by Joaquín Mª López Muñoz 15 Jan '08

15 Jan '08

Hello, Some time ago, there were two places where users could download daily snapshots of the Boost repository: * http://engineering.meta-comm.com/boost.aspx (linked from boost.org) * http://www.boost-consulting.com/boost.tar.bz2 Alas, none of them are being updated anymore. It'd be great if at least one could be put back in business, as this is a very useful service for casual Boost users without SVN tools. Thank you, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

[DateTime] format flag to print single-digit hour?
by Boris 15 Jan '08

15 Jan '08

I'm using the Boost.DateTime IO system to create customized date/time strings. While the library supports quite a lot of format flags out of the box I'm missing a format flag to print a single-digit hour. There is the format flag %k though (see http://www.boost.org/doc/html/date_time/date_time_io.html#date_time.format_…) - however it adds a preceding blank for single-digit hours. I guess there is currently no format flag for single-digit hours? Is it possible then to extend the Boost.DateTime IO system somehow to add your own format flag? While I could use another library like Boost.Format additionally I prefer to stick to one (it might make more sense then to switch to Boost.Format completely)? Boris
