Spirit with UI Tools
by Philipp Kraus 05 Nov '14

05 Nov '14

Hello, I would like to create a small parser with Boost.Spirit. I have run the short examples and everything works well, so I would like to create my own LL grammar. In my case I need also for documentation a EBNF or something else and in the best case I can would like to create the EBNF first and transform this into the Spirit LL grammar code. Did you know any tools to do this? My first idea is to use AntLR to create the grammar but imho it creates a LR grammar. Can you recommend a tool to define the grammar structure and generate the Spirit code? Thanks a lot Phil

Hello, I cannot compile bjam.exe and I see error.

problem with #include <boost/thread.hpp>
by Grison PG Pierre (External DEXIA-US) 04 Nov '14

04 Nov '14

Hello, I encounter a problem with the Thread library. The library works fine when I use it in a .exe project. It means it has been correctly built. Then I try to use the same library in an DLL project (so as to build a XLL object thanks to the XLW library). But as soon as I add the line #include <boost/thread.hpp> to my project, even if it compile without any problem, I get the following message when I debug my project through Excel: The file you are trying to open, "mylibrary.xll" is in a different format than specified by the file extension, Verify that the file is not corrupted [...]. Do you want to open the file now? And I can no more use my C++ functions in Excel. Do you have already encounter this problem? I use VS2010. I have tried both Multi-threaded Debug DLL (/MDd) and Multi-threaded DLL (/MD) options. My solution includes two other static libraries and also with the classic RunInterfaceGenerator XLW-project (the one which is executed when debugging). Regards, Pierre

iterator_facade Boost 1.57
by gast128 04 Nov '14

04 Nov '14

Dear all, Just trying out 1.57, since we are already 5 releases behind due to all kinds of compilation errors with Boost and our software. Below simplified code doesn't compile on vs2010: template <typename DerivedType> struct IteratorFacade : public boost::iterator_facade<DerivedType, int, std::random_access_iterator_tag> { typedef boost::iterator_facade<DerivedType, int, std::random_access_iterator_tag> base; IteratorFacade (); virtual ~IteratorFacade (); friend class boost::iterator_core_access; reference dereference () const; }; struct MyIteratorFacade : IteratorFacade<MyIteratorFacade> { }; What do I wrong?

[Test] How to log output to both stdout in HRF and to a file in XML?
by Martin Ba 03 Nov '14

03 Nov '14

As asked on SO: http://stackoverflow.com/questions/26505229/how-to-log-boost-test-output-to… I would like to enable logging of Boost.Test output to *both* the stdout/sterr and to a logfile. However, I would also like to have the stdout logging be in HumanReadableFormat and only the file output be in XML format. Generating a report file seems to be addressed [here][1]. ([official docs][2]) Choosing the format can be done in [various ways][3], but it seems one is stuck with either HRF or XML? ----------- Rationale: When running tests on or [Jenkins][4] server, the [xUnit plugin][5] [requires][6] the **log** XML output (as opposed to the *report* XML output -- `log_level` vs. `report_level`). However, the in-progress log output (in HRF) is highly valuable *while* the tests are running on the server, to detect hanging tests or to a quick manual check of where the tests currently are. So I want an in-progress HRF log for the tests and at the end I need an XML file containing the `<TestLog>...</TestLog>` output of Boost.Test (not the `<TestResult>` output). Do note that we run both unit as well as integration tests via Boost.Test, so some of them are quite long-running.

ASIO: Windows/Linux/Mac socket inter-operability
by Joost Kraaijeveld 03 Nov '14

03 Nov '14

Hi, I have a C/S-application that uses ASIO-sockets. The application runs fine if I try to connect between 2 Windows or 2 Linus or 2 Mac machineas. However, it fails to work with a "reset by peer" error if I try to connect between Windows and Linux, Windows and Mac or Linux and Mac. Is there anything known about problems wrt inter-os connections, and if so, is there a solution for this? TIA -- Groeten, Joost Kraaijeveld Molukkenstraat 14 6524NB Nijmegen tel: 024-3607445 / 06-51855277
