RE: [Boost-users] Boost Logging Library 1.3 troubles

Hi, John Torjo's latest version (May 19) fixes my problems. Thanks again John. Randy _____ From: boost-users-bounces(a)lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of Ormond, Randy (Mission Systems) Sent: Wednesday, May 11, 2005 11:47 AM To: boost-users(a)lists.boost.org Subject: [Boost-users] Boost Logging Library 1.3 troubles Hi, If I'm following the threads correctly, it looks like John Torjo's logging library may become an official part of Boost someday. It certainly seems to be perfect for my needs. But I'm having all sorts of trouble on Red Hat with gcc 3.2.2-5. I had to modify some source to avoid compile errors, which has me worried given my lack of expertise. In log.hpp, I had to change (sorry, I can't paste in code or compiler output, this is typed in) template<bool is_compile_time, bool is_enabled> struct logger_keeper_is_enabled... to template<bool is_compile_time, bool is_enabledInput> struct logger_keeper_is_enabled... to avoid shadowing is_enabled in ts_posix.hpp, I had to change the mutex ctr from mutex() : m_mutex(0) {... to mutex() {... This seems OK because m_mutex is initialized in the ctr body. After making those changes, I tried the example in the basic_usage.html. It hangs on the first call to BOOST_DEFINE_LOG. I traced it with gdb to find_log_by_name() at log_manager.cpp:294. From there, it goes to the logger_info ctr. It hangs in lwm_pthreads.hpp:72 in the scoped_lock ctr, apparently trying to get a lock. Of course my mods to the source and general lack of insight have me worried. I expect difficulties as an "early adopter" but any help would be greatly appreciated. BTW, is anyone else trying to use this yet? Thanks, Randy

boost.serialization 1.32 example execution fails in MFC project (Visual Studio .NET 2003)
by Yan Zhang 02 Jun '05

02 Jun '05

I installed Boost 1.32 in Windows with Visual Studio .NET 2003. I tested serialization provided in "vc7ide" project, it runs successfully. Of course, all test projects are "Console", no MFC library involved. Then I used the same library in MFC project, the execution failed in function: BOOST_SERIALIZATION_NVP(s) >From MSDN, it was said that Boost is supported in Visual Studio .NET 2003. I labored a week to upgrade our MFC project to Visual Studio .NET 2003 and it still has problem. Any idea? Thanks in advance. Yan

Using boost regex
by Tulio Bender 02 Jun '05

02 Jun '05

Hello,I'm new to boost and regular expressions in general.I'm using sregex_iterator (and the example provided in the documentation as a base) to search for all occurrences of "G0" in a string like these "M51DTnM54G0G1G1G1G1G1G1G1G1G1G1G1G1G1G0G1M54M54G1G0G1G0M54M54G1M54".I tried to use for RE: "G0", "(G0)+" and "(G0)", but it only finds 1 occurrence for "G0" when I expected to find 4. I also need to know the position of each occurrence.Thanks in advance.Tulio Cleber Bender Unisinos University Laboratorio de Automacao Industrial - LAI/C6 Av.

[thread] bug in to_microduration (timeconv.inl)?
by Paolo Coletta 02 Jun '05

02 Jun '05

I needed something to convert the difference between two xtime values to microseconds, so I looked at the to_microduration function in time_conv.inl and I guess that there is a bug there. The if should be: if (boost::xtime_cmp(xt, cur) <= 0) microseconds = 0; else ... In facts, the intent of the if condition seems to be avoiding negative return values, as for the to_duration function. Current code is: inline void to_microduration(const boost::xtime& xt, int& microseconds) { boost::xtime cur; int res = 0; res = boost::xtime_get(&cur, boost::TIME_UTC); assert(res == boost::TIME_UTC); if (boost::xtime_get(&cur, boost::TIME_UTC) <= 0) microseconds = 0; else { microseconds = (int)((xt.sec - cur.sec) * MICROSECONDS_PER_SECOND) + (((xt.nsec - cur.nsec) + (NANOSECONDS_PER_MICROSECOND/2)) / NANOSECONDS_PER_MICROSECOND); } } Paolo

Building boostbook from cvs fails lately.

I've been unable to build the boostbook documentation from the cvs sources for some time now. It used to work, but lately I get the errors below.

Hi Jeff, I installed Boost 1.32 on my computer (Windows Server 2003 and Visual Studio .NET 2003). A directory: \boost_1_32_0 was created. In \boost_1_32_0\libs\serialization\vc7ide, I found the projects for building serialization library and test examples. I can build the library (libboost_serialization.lib) and examples, and they run well. All examples are Windows console applications. Then I created an MFC application, linked it with the library. In Document class, I did a test similar to the one presented in demo_xml.cpp and demo_xml.hpp: ... #include "stdafx.h" #include "MFCTests.h" #include "MFCTestsDoc.h" #include <iostream> #include <sstream> #include <string> #include <boost/archive/tmpdir.hpp> #include <boost/archive/xml_oarchive.hpp> #include "demo_xml.hpp" .... void CMFCTestsDoc::OnTestSerialize() { bus_stop *bs0 = new bus_stop_corner( gps_position(34, 135, 52.560f), gps_position(134, 22, 78.30f), "24th Street", "10th Avenue" ); std::string filename(boost::archive::tmpdir()); filename += "/demo.xml"; std::ofstream ofs(filename.c_str()); assert(ofs.good()); boost::archive::xml_oarchive oa(ofs); oa << BOOST_SERIALIZATION_NVP(*bs0); ... } Execution fails in last statement with message: Unhandled exception at 0x77e55dea in MFCTests.exe: Microsoft C++ exception: __non_rtti_object @ 0x0012e800. The build was debug build, application and library were build with runtime library option "Multi-threaded Debug (/MTd)". I tried to use different options such as "Multi-threaded Debug DLL (/MDd)", it failed the same way. In MSDN (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vst echart/html/boostvc.asp), it discussed Boost for Visual Studio C++. It stated that Boost works well with VC++ 7.1. Of course we know it doesn't work well with previous VC++ such as VC++ 6.0 which I tried and failed badly.

RNG
by Sliwa, Przemyslaw (London) 02 Jun '05

02 Jun '05

All, I have a question which is not related directly to boost. I am writing a multithreaded application and would like to make use of a multiprocessor machine in order to speed up our Monte Carlo simulation engine. We make use of the random number package (random number distributions). My question is: making the random number generator a global variable (object) it is possible to use it in several threads at the same time -> does it mean that the random sequences will be repeated and the entire simulation will be simply a repetition of n non-random sequences? This can be avoided when a lock is acquired on the random number generator and at a given time just one thread can access the rng and the advantage of the multiprocessor machine is lost. Can you advise?

Boost.Tribool: GCC4 and anonymous enums
by Alo Sarv 01 Jun '05

01 Jun '05

GCC4 seems to be rather picky on anonymous enums, and some code seems to break in logic/tribool.hpp with the following error: boost/logic/tribool.hpp: In member function `boost::logic::tribool::operator void (boost::logic::tribool::dummy::*)()() const': boost/boost/logic/tribool.hpp:114: error: `boost::logic::tribool::<anonymous enum>' is/uses anonymous type boost/boost/logic/tribool.hpp:114: error: trying to instantiate `template<class T> struct boost::is_integral' boost/boost/logic/tribool.hpp:114: error: `boost::logic::tribool::<anonymous enum>' is/uses anonymous type boost/boost/logic/tribool.hpp:114: error: trying to instantiate `template<class T> struct boost::is_integral' Same error is repeated at lines 128, 161, and 162 (CVS HEAD). Workaround/patch is obvious (making the enum named), but I haven't managed to create a minimal test-case for the behaviour (the triggering code is rather large and there doesn't seem to be any logic in what actually triggers the error). Any ideas? Alo Sarv
