boost::filesystem::detail::not_found_error with Boost installer on VC2005
by Rainer Thaden 22 Feb '08

22 Feb '08

Hi all, yes, I know, there has been a thread some days ago, but I just registered and don't know how to reply to a mail that I don't have. Anyway, there seems to be a bug in boost 1.34.1 with VC 2005 when using directory_iterator. I used the filesystem before and everything worked fine. Now (since I use the iterator), I get 1>HD2.obj : error LNK2019: Verweis auf nicht aufgelöstes externes Symbol ""unsigned int boost::filesystem::detail::not_found_error" (?not_found_error@detail@filesystem@boost@@3IA)" in Funktion ""private: unsigned int __thiscall boost::filesystem::basic_directory_iterator<class boost::filesystem::basic_path<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,struct boost::filesystem::path_traits> >::m_init(class boost::filesystem::basic_path<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,struct boost::filesystem::path_traits> const &)" (?m_init@?$basic_directory_iterator@V?$basic_path@V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@Upath_traits@filesystem@boost@@@filesystem@boost@@@filesystem@boost@@AAEIABV?$basic_path@V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@Upath_traits@filesystem@boost@@@23@@Z)". I looked into the filesystem dll with depends and found the function there with ordinal 48 (0x30) (in both the debug and the release Version for multithreading). Also in the lib, I found it. Rather strange. The signatures of the linker and the ones found in the DLL also match. I used the installer from Boost-Consulting. In the thread some time ago, a responder claimed, he could compile successfully. Maybe he used a self-compiled boost version? I am going to test that, but maybe somebody has an answer right now? Best regards, Rainer Thaden

Problem using boost::bind with VC2005 (compiler crashes)
by Daniel Lidström 22 Feb '08

22 Feb '08

Hello! I'm trying to use boost::bind and boost::function to perform a callback mechanism. However, the VC2005 compiler crashes for some reason. Let me show the code right away: #include <boost/bind.hpp> #include <boost/function.hpp> #include <boost/any.hpp> #include <boost/noncopyable.hpp> #include <iostream> #include <tchar.h> struct Fl_Widget; typedef boost::function<void (Fl_Widget&, const boost::any&)> CBF_Callback; struct Fl_Widget { CBF_Callback cbf_callback_; boost::any user_data_; //Three calls to set or probe that functor callback variable. CBF_Callback cbf_callback() const {return cbf_callback_;} void cbf_callback(CBF_Callback c, const boost::any& p) {cbf_callback_=c; user_data_=p;} void cbf_callback(CBF_Callback c) {cbf_callback_=c;} //Calls to do the functor callback void do_cbf_callback() {cbf_callback_(boost::ref(*this),user_data_);} // override user_data_ void do_cbf_callback(const boost::any& user_data) {cbf_callback_(boost::ref(*this),user_data);} }; struct GUI : private boost::noncopyable { static GUI& Instance() { static GUI theGUI; return theGUI; } void print() { std::cout << "Inside GUI" << std::endl; } private: GUI(){} }; struct RailCaterpillarControllerGUI { Fl_Widget widget; RailCaterpillarControllerGUI() { // cbToggleDeadZone should be called by widget's callback CBF_Callback callback(boost::bind(&RailCaterpillarControllerGUI::cbToggleDeadZone, this)); widget.cbf_callback(callback); } void cbToggleDeadZone(Fl_Widget& widget, const boost::any& data) { // assume data is reference to the GUI instance boost::any_cast<boost::reference_wrapper<GUI> >(data).get().print(); } }; int _tmain(int argc, TCHAR** argv) { RailCaterpillarControllerGUI controller; controller.widget.do_cbf_callback(boost::ref(GUI::Instance())); } Compiling gives this: 1>------ Build started: Project: test, Configuration: Debug Win32 ------ 1>Compiling... 1>test.cpp 1>c:\users\daniel.sbg\programming\boost_1_34_1\boost\bind.hpp(1575) : warning C4180: qualifier applied to function type has no meaning; ignored 1> c:\users\daniel.sbg\programming\boost_1_34_1\boost\bind.hpp(1609) : see reference to class template instantiation 'boost::_bi::add_cref<Pm,I>' being compiled 1> with 1> [ 1> Pm=void (__thiscall RailCaterpillarControllerGUI::* )(Fl_Widget &,const boost::any &), 1> I=1 1> ] 1> c:\users\daniel.sbg\programming\test\test.cpp(48) : see reference to class template instantiation 'boost::_bi::dm_result<Pm,A1>' being compiled 1> with 1> [ 1> Pm=void (__thiscall RailCaterpillarControllerGUI::* )(Fl_Widget &,const boost::any &), 1> A1=RailCaterpillarControllerGUI * 1> ] 1>c:\users\daniel.sbg\programming\boost_1_34_1\boost\mem_fn.hpp(318) : warning C4180: qualifier applied to function type has no meaning; ignored 1> c:\users\daniel.sbg\programming\boost_1_34_1\boost\bind\bind_template.hpp(22 5) : see reference to class template instantiation 'boost::_mfi::dm<R,T>' being compiled 1> with 1> [ 1> R=void (Fl_Widget &,const boost::any &), 1> T=RailCaterpillarControllerGUI 1> ] 1>Project : error PRJ0002 : Error result 255 returned from 'C:\Program Files\Microsoft Visual Studio 8\VC\bin\cl.exe'.

regexp - how to do an anti-match on a word
by David Ward 22 Feb '08

22 Feb '08

Boosters: I'm having trouble determining a regular expression that will do the following: 1. Match the following strings: TermGeMstreamIPTriplePlay_11.0.IpTxMstream_0.DefaultGateway TermGeMstreamIPTriplePlay_11.0.VplsTxMstream_0.CurMbps TermGeMstreamIPTriplePlay_11.0.MplsTxMstream_0.AvgMbps TermGeMstreamIPTriplePlay_11.0.MacTxMstream_0.Address 2. But not match the string: TermGeMstreamIPTriplePlay_11.0.TrafficTxMstream_0.RampStart So, essentially match the strings with IpTx, VplsTx, MplsTx and MacTx, but not match strings with TrafficTx. Right now, I have: .*\.(IpTx|MacTx|MplsTx|VplsTx)Mstream_0\..* This works, however, it is not very robust because there may be more entries added to the matching words over time. Is there someway to do an anti-match on the word "TrafficTx"? Something like: .*\.(!TrafficTx)Mstream_0\..* Thanks, David

"Re: Boost, HP-UX and gcc"
by stacie＠dcindigos.com 22 Feb '08

22 Feb '08

I'm on 11.23 itanium using gcc 4.1.1 and the latest build of 1.35 beta (feb 21) With my setup, c++config,h indicates that the header wchar.h does exist, however gcc does *not* set _GLIBCPP_USE_WCHAR_T nor_GLIBCXX_USE_WCHAR_T. My build keeps throwing No WCHAR_MIN and WCHAR_MAX errors, and suggests that I adjust integer_traits<>. I was going to just let it slide but unfortunately I received this error while trying to build using the Unit Test framework. Since unit testing is my friend, I would really like to get this working. I tried a work-around from the boost mailing list, but the code that I found in my files was not quite like what he modified: ***** Added code at top of bad header file: #ifdef hpux #include <wchar.h> #undef WCHAR_MIN /* (wchar_t)0 */ #define WCHAR_MIN 0 #endif * error simply changed to: /home/mlinck/develop/api/tp-sources-trunk/boost_1_33_1/boost/regex/v4/regex_traits_defaults.hpp:94:28: error: missing binary operator before token "(" * tried a different workaround at the code where the error is thrown. Noticed that broken code gets skipped for HP_aCC compiler. Figure we can maybe get away with same for gcc compiler: => #if !defined HP_aCC && !defined hpux * seems to compile. Had to apply to boost/regex/v4/perl_matcher.hpp as well ****** How would I modify integer_traits<> ? Since that is what is suggested...... Thanks!

Hi Boris, No help there. I'm still getting the same errors. I'm willing to look at it some more if you have any more suggestions. How can I turn off the building of the python and serialization libraries? There are other libraries that may be broken with HP, too and I'd like to exclude those from the build.

BGL: Finding a vertex by the vertex_index_t property
by Torsten Sadowski 21 Feb '08

21 Feb '08

Hi, is there a simple possibility to find a vertex in a adjacency_list graph by the vertex_index_t property? My uninspired way would be to build a map<int, vertex_descriptor> but there might be something more elegant. Cheers, Torsten

[variant] ideas needed
by ope 21 Feb '08

21 Feb '08

Hi, I've the following code: ---8<--- #include <boost/variant.hpp> #include <iostream> #include <string> struct available : public boost::static_visitor<bool> { template <typename T, typename U> bool operator()( const T&, const U& ) const { return false; // cannot compare different types } template <typename T> bool operator()( const T& lhs, const T& rhs ) const { static const std::string NA( "NA" ); return lhs != NA; //??? } }; using namespace boost; using namespace std; int main() { variant< double, std::string > R; variant< double, std::string > L; R = 3.14; L = "NA"; cout << R << endl; cout << L << endl; bool r = boost::apply_visitor(available(), R ); cout << ( r ? "true" : "false" ) << endl; bool l = boost::apply_visitor(available(), L ); cout << ( l ? "true" : "false" ) << endl; } --->8--- which does not compile. Anyway, from a data parser I get a double or a "NA" (not available) string. This test shall handle both cases. To process using the double I have to check if it available (than use defaults). Unfortunately, the static_visitor<bool> needs two arguments. How can I get the syntax (or simpler) as used in the example? Thanks Olaf

A request for help using the Boost Unit Test Library
by Tim Allison 21 Feb '08

21 Feb '08

I am working on a project that uses the Boost Multi-Index library and Boost shared_ptr, so I know I can use the Boost libraries on our project. However, I am unable to build so much as an example from the Boost Unit Test Library, and need help. (I assume the problem is a conflict with compiler switches, or something along those lines.) I set up a test directory, into which I will link the source code I wish to test. The Make file I am using is a modified form of one we use to build my project, so I know it will build both the module using some Boost libraries, and our old code, some of which is more than 10 years old. I am using boost 1.33.1-42@586 on Suse 10.2 (If it matters, my computer is a Latitude D510) and Gnu compiler 4.1.3-29@586 (as listed by Smart Package Manager). When I run the make file, it echos out the following line: g++ -Wno-deprecated -frepo -m32 -g -I../lib -I/usr/X11R6/include -I../../../source/ecs/shared -DOS_IS_LINUX -c FuserTests.cc FuserTests.cc is the file into which I have attempted to copy the examples. (The examples are both from the patmedia.net/rogeeff site, and the official boost site, as corrected within the discussion forum.) The case I am most interested in running uses BOOST_AUTO_TEST_CASE( functionName ). This line produces the error: FuserTests.cc:16: error: expected constructor, destructor, or type conversion before ‘(’ token Is there something special I need to do to get this to compile in C++? -- Tim Allison Chief Engineer MIDCON Millennium Engineering and Integration (719) 264-4302 Work (719) 264-4318 Fax
