vc8 / 2005 linker problems in program_options
by Andrew Schweitzer 19 Feb '07

19 Feb '07

I'm having problems building programs with program_options and vc8/2005. I'm getting linker errors... any suggestions? I suspect I'm doing something obvious wrong. Linking against 1.33.1, I have $(BOOST_ROOT)\bin\boost\libs in "Additional Library directories". I get "already defined" and "unresolved" errors when I try to use program_options code that builds in vc71. For example: //no problem here... #include <boost/program_options.hpp> using namespace std; using namespace boost; using namespace boost::program_options; void func() { //but with this I get linker errors variables_map l_vm; } //...such as: 1>libboost_program_options-vc80-mt-gd-1_33_1.lib(variables_map.obj) : error LNK2005: "class std::basic_ostream<char,struct std::char_traits<char> > & __cdecl std::operator<<<char,struct std::char_traits<char>,class std::allocator<char> >(class std::basic_ostream<char,struct std::char_traits<char> > &,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &)" (??$?6DU?$char_traits@D@std@@V?$allocator@D@1@@std@@YAAAV?$basic_ostream@DU?$char_traits@D@std@@@0@AAV10@ABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@0@@Z) already defined in msvcprtd.lib(MSVCP80D.dll) //and: 1>libboost_program_options-vc80-mt-gd-1_33_1.lib(options_description.obj) : error LNK2019: unresolved external symbol "__declspec(dllimport) public: class std::reverse_iterator<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::const_iterator> __thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::rbegin(void)const " (__imp_?rbegin@?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QBE?AV?$reverse_iterator@Vconst_iterator@?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@2@XZ) referenced in function "public: bool __thiscall boost::program_options::option_description::match(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &,bool)const " (?match@option_description@program_options@boost@@QBE_NABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@_N@Z) Any suggestions?

bjam crashes
by Andrew Schweitzer 18 Feb '07

18 Feb '07

Hi there. When I run bjam 3.1.12 or 3.1.13, bjam crashes. Any ideas, suggestions? I wouldn't be surprised if I'm doing something obvious wrong. I'm trying to build on XP Pro, VC7, VC8. 1.33.1 Bjam 3.1.10 vc7 or vc8 Works! 1.33.1 Bjam 3.1.12 vc7 or vc8 kaboom 1.33.1 Bjam 3.1.13 vc7 or vc8 kaboom cvs Bjam 3.1.10 vc7 or vc8 says bjam >= v12 needed. cvs Bjam 3.1.12 vc7 or vc8 kaboom cvs Bjam 3.1.13 vc7 or vc8 kaboom Thanks Andy

When bjam is run on the examples folder on fedora core 4 it generates linker errors. Such as: ../../../bin/boost/libs/interprocess/example/process_a_example/gcc/release/runtime-link-static/process_a_example.o(.text+0x340): In function `main': process_a_example.cpp: undefined reference to `sem_post' NB: Does this help? [root@localhost example]# gcc -v Using built-in specs. Target: i386-redhat-linux Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-libgcj-multifile --enable-languages=c,c++,objc,java,f95,ada --enable-java-awt=gtk --with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre --host=i386-redhat-linux Thread model: posix gcc version 4.0.2 20051125 (Red Hat 4.0.2-8) Thanks

Boost compilation error
by Gunjan 18 Feb '07

18 Feb '07

I am not able to compile Boost libraries through command line (gcc compiler on Windows). It is giving the error: fatal error C1083: Cannot open include file: 'boost/config.hpp': No such file or directory I searched on the net and found this is a common problem and should get solved by adding the path for Boost libraries to the include environment variable. But it is not happening. My observation is that its not identifying the path correctly. If I change the path manually (changing it to ‘”config.hpp” instead of <boost/config.hpp>), it proceeds with compilation. But that is not desired and practical. Can someone help me solving this problem? Thanks in advance.

[Program options] Some questions about composing.
by Seweryn Habdank-Wojewódzki 18 Feb '07

18 Feb '07

Hi all Is that possible to use "unsigned int" type in: config.add_options() ("source-columns,c", po::value< vector<unsigned int> >()->composing(), "List of columns. Can be: 1 2 34 5 2."); If I change "unsigned int" to "std::string" it works good. I mean I can use: -c 1 2 34 5 2 and it works. Regards. -- |\/\/| Seweryn Habdank-Wojewódzki `\/\/'

[property map] copying dynamic_properties
by gavinband＠tiscali.co.uk 18 Feb '07

18 Feb '07

Dear all, I have boost 1.33.0. It looks to me like boost::dynamic_properties (in dynamic_property_map.hpp) does not have a supplied copy-constructor, and so it has a default copy-constructor. However, since dynamic_properties allocates dynamic_property_map objects on the heap, and holds them by pointer, this is not sufficient. This is causing a segfault in the code pasted below. Either dynamic_properties should be given a copy constructor and assignment operator (which seems useful to me) or it should be noncopyable. Or perhaps it could use shared_ptrs instead of regular pointers to avoid this problem? Thanks, Gavin. #include <boost/dynamic_property_map.hpp> int main() { std::map<long,long> my_map; boost::associative_property_map<std::map<long,long> > apm(my_map); boost::dynamic_properties dp; dp.property("property",apm); boost::dynamic_properties dp2(dp); // crash occurs when dp is destructed. return 0; } ___________________________________________________________ Tiscali Broadband only 9.99 a month for your first 3 months! http://www.tiscali.co.uk/products/broadband/

[iterator] make_zip_iterator
by Erik Åldstedt Sund 18 Feb '07

18 Feb '07

Hi, just a short question: Why does not the zip_iterator header have the following (or something along the lines of the following) creator function: template <typename Iter1Type, typename Iter2Type> boost::zip_iterator<boost::tuple<Iter1Type, Iter2Type> > make_zip_iterator(Iter1Type i, Iter2Type j) { return boost::make_zip_iterator(boost::make_tuple(i, j)); } That would make creating a zip_iterator much simpler. Instead of writing the following: std::set<double> s; std::vector<int> v; // populate s and v.... std::for_each(boost::make_zip_iterator(boost::make_tuple(s.begin(), v.begin())), boost::make_zip_iterator(boost::make_tuple(s.end(), v.end())), my_functor_that_does_something_useful()); you could write the following: std::set<double> aSet; std::vector<int> aVector; // populate aSet and aVector.... std::for_each(boost::make_zip_iterator(aSet.begin(), aVector.begin()), boost::make_zip_iterator(aSet.end(), aVector.end())), my_functor_that_does_something_useful()); Regards, Erik Åldstedt Sund

[bimap] Review of the Bimap library begins today Feb 15
by Ion Gaztañaga 18 Feb '07

18 Feb '07

Hello everyone, The review of the proposed Boost Bimap library written by Matias Capeletto starts today (February 15th, 2007) and ends after 10 days (February 25, 2007). Documentation for the library can be found online here: http://tinyurl.com/e2os3 The library can be downloaded from Boost.Vault/Containers: URL: http://www.boost-consulting.com/vault/index.php?directory=Containers Tiny URL: http://tinyurl.com/ysfclr Online documentation and the documentation package can be found here: http://tinyurl.com/y95qng --------------------------------------------------- Context: The library has been developed by Matias Capeletto with the mentoring of Joaquín M López Muñoz in the context of the Google SoC 2006. You can find more information about SoC projects here: http://code.google.com/soc/boost/about.html You can read an overview of Boost participation in Google Summer of Code 2006 written by Joaquín M López Muñoz here: http://boost.org/more/boost_soc_06_overview.html --------------------------------------------------- About the library: With Boost.Bimap you can create associative containers in which both types can be used as key. A bimap<X,Y> can be thought of as a combination of a std::map<X,Y> and a std::map<Y,X>. The learning curve of bimap is almost flat if you know how to use standard containers. A great deal of effort has been put into mapping the naming scheme of the STL in Boost.Bimap. The library is designed to match the common STL containers. Boost.Bimap offers also advanced features: -> Boost.Bimap offers much more than just a one-to-one ordered unique bidirectional map. It is possible to control the set type of each side of the relationship that the bimap represents, giving one-to-many containers, hashed bidirectional containers and others that may be more suitable to the the task at hand. -> The types of a bimap can be tagged so that each side is accessible by something closer to the problem than left and right. This leads to more readable, self-documenting code. -> The extended mapping framework allows to disable a view of a bimap, including the standard mapping containers as a particular case. Bimap has been tested in the following platforms: GCC 3.4/Linux GCC 4.0/Linux, Mac VS 7.1/Windows VS 8.0/Windows ICC 7.1/Windows ICC 8.0/Windows --------------------------------------------------- Please always state in your review, whether you think the library should be accepted as a Boost library! Additionally please consider giving feedback on the following general topics: - What is your evaluation of the design? - What is your evaluation of the implementation? - What is your evaluation of the documentation? - What is your evaluation of the potential usefulness of the library? - Did you try to use the library? With what compiler? Did you have any problems? - How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? - Are you knowledgeable about the problem domain?

Building Universal Boost Libraries on MacOS
by Finley Lee 18 Feb '07

18 Feb '07

Greetings, list! I'm trying to compile the boost libraries on an Intel based Macintosh. On my Intel Mac, I was able to build an Intel based version of bjam, which happily builds libraries for the Intel architecture. I want to link them to a universal app, though. Is there a way to instruct bjam to build universal versions of the libraries instead? I guess I could build the PowerPC libraries on my PowerPC Mac and them lipo them together, but I am hoping there is an easier way! Best regards, Finley
