[serialization] newbie compilation question
by lenberman 21 Feb '09

21 Feb '09

I've got boost 1.38 built. When I try to build demo.cpp, it fails. I'm building in the serialization/examples subdirectory. I think this is a supported compiler. No doubt I'm doing something very stupid and hopefully very easy to fix. Thanks in advance. --Len make -k g++ --version g++ (Debian 4.3.2-1.1) 4.3.2 Copyright (C) 2008 Free Software Foundation, Inc.

OT: generic template type from specific type?
by Neal Becker 21 Feb '09

21 Feb '09

Say I have: template<typename in_t> void F (in_t & in) ... main() { F<std::vector<int> > (...) Suppose in_t is a templated container, such as std::vector<int>. Is there a way within the function 'F' to get the generic container type, 'std::vector' when F is instantiated with a specific e.g., std::vector<int>? Maybe I'm missing something obvious :)

[serialization][build][spirit][repost] Problems with spirit when building 1.38 serialization on windows with Intel C++ 11.0
by Jesse Perla 21 Feb '09

21 Feb '09

Sorry for the repost, but it looks like the formatting on my previous post was messed up, and I wouldn't blame people for not reading it I am on windows using the latest version of the intel compiler (set in my user-config.jam). I was able to do a debug build of everything using: bjam link=static debug stage But when I tried to do a release build, it is popping up a spirit error for serialization(fails with or without mpi). Any ideas on a workaround or if this is a legit bug? The main error in the build output is: C:\apps\boost\boost_1_38_0\boost\spirit\home\classic\utility\impl\chset\range_run.ipp(142) (col. 21): internal error: 0_1504 compilation aborted for libs\serialization\src\xml_grammar.cpp Full output: bjam --with-mpi link=static release stage ...patience... ...found 1080 targets... ...updating 4 targets... compile-c-c++ bin.v2\libs\serialization\build\intel-win\release\link-static\thre ading-multi\xml_grammar.obj icl: command line remark #10010: option '/Op' is deprecated and will be removed in a future release.

[shared_ptr] Is reference counting thread safe in boost 1.38
by dhruva 21 Feb '09

21 Feb '09

Hello, I am trying to replace a home grown shared pointer which uses expensive lock (mutex) to make the increment and decrement thread safe. I went through the boost code and see it uses atomic operations. I am not able to figure out if the following case is handled: 1. Thread 1 has a shared_ptr and hence the reference is 1 2. Thread 1 is in the process of decrementing the reference and thread 2 is in the process of incrementing the the reference 3. If thread 1 succeeds in decrementing, the reference will become 0 and hence 'destroy' will get called. 4. Can thread 2 increment after when thread 1 is in a call to destroy? The reference count variable is itself protected but is the call to destroy and reference count variable synchronized? -dhruva Add more friends to your messenger and enjoy!

ambigous bitshift operator for ubig64_t ?
by Ákos Maróy 21 Feb '09

Hi, I'm trying to compile the following code: #include <boost/spirit/home/support/detail/integer/endian.hpp> boost::integer::ubig64_t big_endian_value; big_endian_value >> 1; but I get: error: ambiguous overload for 'operator>>' in 'big_endian_value >> 1' note: candidates are: operator>>(long long unsigned int, int) <built-in> ../../usr/include/boost-1_38/boost/spirit/home/support/detail/integer/cover_operators.hpp:53: note: long long unsigned int boost::integer::operator>>(const boost::integer::endian<big, long long unsigned int, 64u, unaligned>&, long long unsigned int) what am I doing wrong? (BTW, the same works with the >>= operator) I'm doing this on Linux, gcc 4.1.2 Akos

boost::exception - leaking error_info
by Bruce Laing 21 Feb '09

21 Feb '09

This program seems to be leaking boost::exception::error_info objects. Is there something missing here? - Bruce typedef boost::error_info< struct tag_my_error, std::string > some_error_info; struct an_exception : public boost::exception, public std::exception {}; void throw_func() { BOOST_THROW_EXCEPTION ( an_exception() // no leak if next line is commented out. << some_error_info( std::string( "error message" ) ) ); } . . . BOOST_AUTO_TEST_CASE( test_exceptions ) { try { throw_func() } catch( an_exception& ) { } }

boost_regex link problems
by Colin Hercus 21 Feb '09

21 Feb '09

Hi, I'm trying to use Boost regex for the first time and I'm having trouble getting libboost_regex to link. The libraries are in /usr/lib64 and I try adding -lboost_regex to CC command and also explicitly adding /usr/lib64/libboost_regex.so or .a but I keep getting the same linker errors whether the library is specified or not.

[Python] can't import boost modules in an embedded interpreter

I solved my problem. I had to add the current directory (where the executable is) to sys.path at the beginning of the program before python files are picked up as modules in the embedded interpreter. George
