[Python][TR1] Broken in V1.35 if Boost.Python used with Boost.TR1
by Hartmut Kaiser 17 Apr '08

17 Apr '08

Hi all, compiling Boost Python while having the Boost TR1 headers in the include path is broken in V1.35 (trunk as well, BTW), at least while using VC8.1 on Windows or gcc on Cygwin. The simplest way to reproduce this is: create a file test.cpp: #include <boost/python.hpp> Compile it with: cl -c -MDd -I$PYTHON_ROOT\include -I$BOOST_ROOT -I$BOOST_ROOT\boost\tr1\tr1 test.cpp or gcc -c -I$PYTHON_ROOT/include -I$BOOST_ROOT -I$BOOST_ROOT/boost/tr1/tr1 test.cpp voila! Lots of errors. Regards Hartmut

some bug in serialization/utility.hpp

i have writed a program with stl::map serialization //note : although the program use boost.mpi ,i think this bug have no relation with mpi,is just the utility . #include<iostream> #include<boost/serialization/nvp.hpp> #include<boost/serialization/map.hpp> #include<boost/mpi.hpp> int main(int argc, char ** argv) { using namespace boost::serialization; using namespace boost::mpi; using namespace std; environment env(argc, argv); communicator world; map<int ,double> ws; if (world.rank() == 0) { world.send(1,1, boost::serialization::make_nvp("ws", ws)); } else { world.recv(0,1,boost::serialization::make_nvp("ws", ws)); } return 0; } the erro is : /home/ws/boost-1-35/include/boost-1_35/boost/serialization/utility.hpp:48: error: expected template-name before '<' token /home/ws/boost-1-35/include/boost-1_35/boost/serialization/utility.hpp:48: error: expected `{' before '<' token /home/ws/boost-1-35/include/boost-1_35/boost/serialization/utility.hpp:48: error: expected unqualified-id before '<' token

Hello, become iterators of an ordered_non_unique index invalidated if I call: iterator erase(iterator position)? Or are all other iterators still valid and point to the same item as before? thx! Oliver

[boost.pool] Workaround for a msvc 7.1 & 8.0 bug surfaced in the boost 1.35 release
by Jurko Gospodnetić 17 Apr '08

17 Apr '08

Hi all. One of our projects failed to build using the Boost 1.35 release and we traced it down to a compiler bug with MSVC 7.1. & 8.0. We have not tested any earlier compiler versions and MSVB 9.0 seems to have fixed the bug (and seems to compile the project in about half the time it took in MSVC 8.0 :-)))). We found a fix that should be applied to boost/pool/detail/mutex.hpp: The CRITICAL_SECTION type should be referenced using its fully qualified name '::CRITICAL_SECTION'. I am attaching a suggested patch file for boost/pool/detail/mutex.hpp. If no problems are found with it should be applied to the trunkas well as the release branch for the upcoming 1.35.1 patch release. The patch uses fully qualified names for other global Windows/posix API calls as well (e.g ::InitializeCriticalSection(), ::DeleteCriticalSection(), ::EnterCriticalSection(), ::LeaveCriticalSection()) but that does not have direct impact on this concrete bug. The following source file demonstrates the bug using boost libraries: #include "boost/archive/text_iarchive.hpp" #include "boost/pool/pool_alloc.hpp" int main() {} It should fail to build with an error message similar to: X:\Resources\Libraries\Boost\boost_1_35_0\boost\pool\detail\mutex.hpp(67) : error C2872: 'CRITICAL_SECTION' : ambiguous symbol could be 'X:\Resources\Libraries\PlatformSDK\Version_6.0\Include\WinBase.h(314) : RTL_CRITICAL_SECTION CRITICAL_SECTION' or 'X:\Resources\Libraries\Boost\boost_1_35_0\boost\detail\lwm_win32_cs.hpp(33) : boost::detail::CRITICAL_SECTION' Perhaps someone knows how and where to add the above example as a part of some regression test suite on MSVC 7.1 & 8.0? Here is also a minimal example demonstrating the same compiler bug without using any external libraries: namespace One { class Brick; } namespace Two { using namespace One; template <class TinyTemplateParam> class TinyClass {}; } class Brick {}; Brick brick; int main() {} Hope this helps.

[Proto] Review result
by Hartmut Kaiser 16 Apr '08

16 Apr '08

Hi all, initially I was hoping to find some time over the last weekend to go through the reviews in great detail to put together a proper review report. Well, as things happen, I was not able to find the time :-( To avoid further delays, here is the short version of the review result: Proto got 16 reviews (That's well above average! Thanks to all for participating), out of which 15 have been positive. The one 'No' essentially stated that the library, even if doubtless very useful, shouldn't be accepted yet, mainly because there has to be done more work in the area of formalizing the problem domain. In my opinion this is an overwhelming result and I'm whole heartily agreeing with the majority of the voters. Proto is accepted as a Boost library. The discussions have been very detailed and there have been raised a lot of (mostly minor) issues, but Eric is aware of the problems and is working on solving them. I'll try to put together a summary as soon as possible. Regards Hartmut Review Manager

Avoiding boost::noncopyable error.
by Emre Turkay 16 Apr '08

Hi folks, In the example below, while (1) is compiling fine, (2) causes compiler error in linux gcc 4.1.3. I certainly don't want to copy the member variable of the object in copy constructor, and I need T2. How can I handle it? Thanks, emre #include <boost/noncopyable.hpp> struct A: boost::noncopyable { }; template <typename T> struct B { B() { } B(const B<T>& b) { } // (1) template <typename T2> B(const B<T2>& b) { } // (2) private: T a; }; int main() { B<A> b1; B<A> b2(b1); }

[serialization]

We've discovered an issue Boost has writing and reading wide character strings (wchar_t* and std::wstrings) to non-wide character file streams (std::ifstream and std::ofstream). The issue stems from the fact that wide characters are written and read as a sequence of characters (in text_oarchive_impl.ipp and text_iarchive_impl.ipp, respectively). For text streams, an EOF character terminates the reading of a file on Windows. Some wide characters have EOF (value = 26 decimal) as one of the bytes so reading that byte causes early termination of the read. We have worked around the issue by deriving our own input and output archives from text_i|oarchive_impl<Archive> and overriding load_override() and save_override for std::wstring and wchar_t*. Our implementation just sequences through the wide characters and writes them 1 by 1 as wchar_t to the archive. This isn't very elegant and is even less readable in the file than the current implementation but does resolve the problem. I looked at both Boost 1.34.1 and 1.35 and didn't see a difference in the implementation here so I'm assuming 1.35 still has the issue. I've been working with 1.34.1. Is this a known issue? Does 1.35 solve it in some other subtle way? Is there a better way that doesn't require us to derive our own streams? If not, is there a more elegant way of implementing the reading and writing of wide characters ourselves? Thanks in advance. Jeff Faust

<windows.h> policy?
by Emil Dotchevski 16 Apr '08

The header date_time/microsec_time_clock.hpp (which is used by the Thread lib) includes <windows.h>. I noticed because a call to std::min() in my own code stopped compiling after I switched a project to compile against the current boost trunk. What is the official policy for including such platform-specific headers? I hope that this is a bug! -- Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
