[PropertyTree] Request to have string_path.get_separator()
by Gábor Márton 21 Nov '11

21 Nov '11

Hi, I am implementing my own read function to populate a property tree: void read_imm(const boost::property_tree::path& path, boost::property_tree::ptree& pt); The first parameter is to specify the root of the configuration tree, from where the property tree will get it's values. However in the implementation of read_imm the path must be parsed and reversed. For that I need to know the separator of the path. Currently, I have the following workaround to get the separator: char getSeparator(const boost::property_tree::path& path) { assert(!path.single()); assert(!path.empty()); std::string pathStr = path.dump(); namespace bpt = boost::property_tree; bpt::path pathCopy(path); std::string first = pathCopy.reduce(); return pathStr.at(first.length()); } This is inconvenient , so this letter is to request a public member function to get the separator to ease the use of boost::property_tree::path. Thanks, Gabor

[xpressive] Stack overflow with small stacks without compiler optimization turned on
by Ovanes Markarian 21 Nov '11

21 Nov '11

Hello *, I currently ran into the issue with xpressive. One of our test suites limits the stack usage to 32K and we have a stack overflow with over 600 function calls within xpressive. I stripped down our test case to the minimally reproducible source: #include <boost/xpressive/xpressive.hpp> #include <iostream> #include <string> using namespace boost::xpressive; namespace x=boost::xpressive; using namespace std; const sregex allowed_chars = x::set[alnum | (x::set= '_','-','+','.')]; sregex regex(string const& delim) { return bos // begin of sequence followed by >> !(s1=as_xpr(delim)) // zero or one delimiter (greedy) >> (s2=*(allowed_chars|as_xpr(delim)))// any number of allowed characters mixed with delim string ; } int main() { const string s = "Process.DiagBuffer"; string delim; cout << "enter delim: "; cin >> delim; smatch what; bool matched = regex_match(s, what, regex(delim)); const string suffix=what[s2]; cout << suffix << endl; return 0; } Compilation Platform is Linux 32 bit. Compiler call: g++ -g -I"../software/boost_1_47_0" -o test main.cpp For that source the stack has to be limited to 24K. You can set the stack size and core dump file size like this: $ ulimit -c 10000 -s 24 Consider using ulimit in the sub-shell, since stack size can't be increased anymore. If you are interested I can post the compiled executable and the core dump file. When using optimization this works fine (it crashes with stack size being less equal 12K), but the main question is: Is it really normal to have more than 600 function calls in Debug mode? Many thanks, Ovanes

boost 1.48, Qt and [Parse error at "BOOST_JOIN"] error
by qplace 20 Nov '11

20 Nov '11

When I switched from boost 1.47 to 1.48 I started to get multiple compile-time errors: Parse error at "BOOST_JOIN", pointing to boost/type_traits/detail/has_binary_operator.hp(50) Falling back to 1.47 made this problem go away. I found discussion about this problem here: http://thread.gmane.org/gmane.comp.lib.boost.user/71406/focus=71459 There is a solution suggested in the above thread, but it is specific to the software that the author has problems with. Risking double-post, (I posted in this thread as well), I'd like to ask for generic suggestion of fixing this problem in 1.48.

[Boost.Test] reporting tests with warnings
by Olaf Meeuwissen 20 Nov '11

20 Nov '11

Hi all, For our CI setup I would like to be able to report the following results from our unit test suite: - number of tests aborted (started but did not complete) - number of tests failed - number of tests passed without warnings - number of tests passed with warnings The first two are supported just fine but the last two are collapsed into a single count in the reports. In the logs, I can make out the warning messages from the passing tests, but I can't seem to get at a count of the number of such tests in the (XML) reports. Any suggestions? Thanks in advance, -- Olaf Meeuwissen, LPIC-2 FLOSS Engineer -- AVASYS CORPORATION FSF Associate Member #1962 Help support software freedom http://www.fsf.org/jf?referrer=1962

[lambda] Using Boost.Lambda with overloaded operators on user defined types
by DeVill 19 Nov '11

19 Nov '11

Hi! I can work around this one easily, but I'm really interested what's wrong with it, and spent 2 days searching in vain. I have in SnakeCube.h the following: typedef boost::multi_array<int, 3> SnakeCubeSolution_t; typedef std::tr1::function<void(const SnakeCubeSolution_t&)> SnakeCubeSolutionCallback_t; typedef std::vector<int> SnakeCubeConstraint_t; void solveSnakeCube( const SnakeCubePosition_t& constraint, SnakeCubeSolutionCallback_t callback); std::ostream& operator<< (std::ostream& out, SnakeCubeSolution_t solution); I included <vector> <ostream> <boost/tr1/functional.hpp> <boost/multi_array.hpp> Function implementations do not seem important, since the problem persists with empty functions. --- The part that won't compile is the last line of main.cpp (Error message at the end of the post) #include <algorithm> #include <iostream> #include <boost/assign/std/vector.hpp> #include <boost/lambda/lambda.hpp> #include "SnakeCube.h" using namespace std; using namespace boost::assign; int main(int argc, char* argv[]) { using boost::lambda::_1; SnakeCubeConstraint_t constraint; constraint += 0,0,1,1,1,0,1,1,0,1,1,1,0,1,0,1,1,1,1,0,1,0,1,0,1,0,0; solveSnakeCube( constraint, cout << _1); // Other versions I tried: //solveSnakeCube( constraint, boost::ref(cout) << _1); //solveSnakeCube( constraint, boost::lambda::ret<ostream&>( cout << _1 ) ); } The easy way out is renaming the operator to printSoution, and use bind(printSolution, boost::ref(cout), _1) instead of cout << _1. Can someone please point me in the right direction on this matter?

Building Boost 1.48 using Intel compiler

First time posting to a mailing list, sorry if I've messed something up. I'm trying to build Boost 1.48 using Intel XE 12.1 and when running bjam it brings up "Windows can't open this file" for each file. I tried to adapt instructions from here: http://software.intel.com/en-us/articles/building-boost-with-intel-c/ I added the following to user-config.jam: using intel-win : 12.1 : "C:/Program Files (x86)/Intel/Composer XE/bin/ia32/icl.exe" : intel "C:/Program Files (x86)/Intel/Composer XE/bin/iclvars_ia32.bat" ; I tried building with the following command: C:\Users\blanked\Desktop\boost_1_48_0>bjam --toolset="intel" "-sINTEL_PATH=C :\Program Files (x86)\Intel\Composer XE\bin\ia32\" "-sINTEL_BASE_MSVC_TOOLSET=vc -10_0" "-sINTEL_VERSION=12.1" Building the Boost C++ Libraries.

has_binary_operator.hpp error

Hello list. I just upgraded my system to the newest version of boost, i.e., 1.48.0. Boost compiled just fine. However, I recompile my applications (that link to boost) and I get the following error: ****************************************************************** usr/local/include/boost/type_traits/detail/has_binary_operator.hp:50: Parse error at "BOOST_JOIN" ****************************************************************** Any suggestions? Regards, Panagiotis Foteinos

BOOST ASIO relation between I/O Service and a Socket and a Thread
by Gokulakannan Somasundaram 19 Nov '11

19 Nov '11

Hi, By going through ASIO, i find that the I/O Service gets run on a thread and the socket gets created with a I/O Service. So the data for the socket has to be always sent through the same thread. For trying take advantage of data localization, i am exploring whether it would be possible to have a thread per multi-core processor running the io_service::run() method. I am just wondering there is a way where in i can change the io_service associated with the socket. Can someone help me with that? Thanks, Gokul.
