Serialization of ptr_container
by Merrill Cornish 24 Nov '05

Since I can find no specific mention that ptr_container classes can be serialized, I assume that means they can NOT be serialized. Right? Merrill

about serialization

Hi, I am using MSVC 7.1, and I need to use the boost_1_33_0 Serialization Library. But I can't make libs\serialization\example\demo.cpp work. It always pops memory alloc error. Can anybody kindly tell me how to make serialization library work? Thanks. --------------------------------- 雅虎邮箱超强增值服务－2G超大空间、pop3收信、邮件提醒

linking with visual studio .net 2003 and regex
by louis 24 Nov '05

24 Nov '05

Hi, I built regex as a library using the source (UNICODE char set but not with ICU support). I am able to link to the library in a console program but when I try and link to the library from an MFC project I get a bunch of unresolved errors. Here is one of them: myapp error LNK2019: unresolved external symbol "public: class boost::basic_regex<wchar_t,struct boost::regex_traits<wchar_t,class boost::w32_regex_traits<wchar_t> > > & __thiscall boost::basic_regex<wchar_t,struct boost::regex_traits<wchar_t,class boost::w32_regex_traits<wchar_t> > >::assign(wchar_t const *,wchar_t const *,unsigned int)" (?assign@?$basic_regex@_WU?$regex_traits@_WV?$w32_regex_traits@_W@boost@@@boost@@@boost@@QAEAAV12@PB_W0I@Z) referenced in function "public: class boost::basic_regex<wchar_t,struct boost::regex_traits<wchar_t,class boost::w32_regex_traits<wchar_t> > > & __thiscall boost::basic_regex<wchar_t,struct boost::regex_traits<wchar_t,class boost::w32_regex_traits<wchar_t> > >::assign(wchar_t const *,unsigned int)" (?assign@?$basic_regex@_WU?$regex_traits@_WV?$w32_regex_traits@_W@boost@@@boost@@@boost@@QAEAAV12@PB_WI@Z) Any help would be greatly appreciated

Serialization documentation suggestion
by Merrill Cornish 24 Nov '05

24 Nov '05

It would be useful to Boost serialization users if there were a section in the serialization documentation titled, say, "Serialization Data Types" with a list such as * all built-in C++ data primitives * all STL containers * all Boost smart pointer types * boost::variant and any other Boost types that can be serialized (boost::any? boost::mutex? etc.) As it stands now, the serialization documentation mentions some, but the comments are scattered. The documentation is silent on other Boost-created data types. Merrill

Re: [Boost-users] Serializing boost::variant?
by Merrill Cornish 24 Nov '05

24 Nov '05

Robert, >>> or you just do: >>> #include <boost/serialization/variant.hpp> I knew that a boost::variant data member in serialize() would compile, but--as the mathematicians say--the a necessary, but not sufficient condition. Thanks for verifying it. Merrill

about installation
by Johnny Wong 24 Nov '05

24 Nov '05

Hi, I am using Borland C++ compiler 5.5, and I need to use the Boost Graph Library. But I am new to C++, so I downloaded the boost_1_33_0 but I don't know how to install and make it work. I have read the getting started guide, but I cannot follow the instructions. Can anybody kindly tell me how to do? Thanks. _______________________________________ �x��ӍϢ - Yahoo!

Using Boost 1.33 with STLport 5.0 on MSVC71
by Wu Yinghui, Freddie 24 Nov '05

24 Nov '05

Dear all, I'm having a problem linking the simplest Boost unit_test program on the platform described above. More details here: Compiler: MSVC71 OS: WinXP Pro SP2 STLport 5.0 config: All default as obtained from CVS STLPORT_5_0 branch, except that I use /Zc:wchar_t to use wchar_t as built-in type. Boost 1.33/34: All default as obtained from CVS, built with the following command line: bjam --without-python "-sBUILD=debug release <runtime-link>static <threading>multi <stlport-version>5.0 <native-wchar_t>on <define>BOOST_SIGNALS_NAMESPACE=siglib" stage My simple unit_test program: ===== #include <string> #define BOOST_AUTO_TEST_MAIN #include <boost/test/auto_unit_test.hpp> BOOST_AUTO_UNIT_TEST( Test_Function ) { std::wstring string = L"some test string"; BOOST_CHECK( string.length() == 16 ); } ===== My project setting uses "Multi-threaded DLL (/MD)" in code gen, and links to "libboost_unit_test_framework-vc71-mt-sgdp.lib" in debug mode. My purpose was to use STLport in a DLL, but the whole Boost statically linked. (I know I can link with "libboost_unit_test_framework-vc71-mt-gdp.lib," but I want Boost to be statically linked.) The linker gives the following errors: stlportstld.5.0.lib(stlportstld.5.0.dll) : error LNK2005: "public: __thiscall stlpd_std::__owned_list::~__owned_list(void)" (??1__owned_list@stlpd_std@@QAE@XZ) already defined in libboost_unit_test_framework-vc71-mt-sgdp.lib(unit_test_suite.obj) stlportstld.5.0.lib(stlportstld.5.0.dll) : error LNK2005: "public: __thiscall stlpd_std::basic_string<char,class stlpd_std::char_traits<char>,class stlpd_std::allocator<char> >::~basic_string<char,class stlpd_std::char_traits<char>,class stlpd_std::allocator<char> >(void)" (??1?$basic_string@DV?$char_traits@D@stlpd_std@@V?$allocator@D@2@@stlpd_std@@QAE@XZ) already defined in libboost_unit_test_framework-vc71-mt-sgdp.lib(unit_test_suite.obj) stlportstld.5.0.lib(stlportstld.5.0.dll) : error LNK2005: "public: static void __cdecl stlpd_std::__node_alloc<1,0>::deallocate(void *,unsigned int)" (?deallocate@?$__node_alloc@$00$0A@@stlpd_std@@SAXPAXI@Z) already defined in libboost_unit_test_framework-vc71-mt-sgdp.lib(unit_test_suite.obj) stlportstld.5.0.lib(stlportstld.5.0.dll) : error LNK2005: "public: class stlpd_std::basic_string<char,class stlpd_std::char_traits<char>,class stlpd_std::allocator<char> > & __thiscall stlpd_std::basic_string<char,class stlpd_std::char_traits<char>,class stlpd_std::allocator<char> >::assign(char const *,unsigned int)" (?assign@?$basic_string@DV?$char_traits@D@stlpd_std@@V?$allocator@D@2@@stlpd_std@@QAEAAV12@PBDI@Z) already defined in libboost_unit_test_framework-vc71-mt-sgdp.lib(unit_test_log.obj) <more similar errors removed...> Is there any kind soul here can enlighten me a bit? Is it at all recommended (or even possible) to use STLport in DLL while statically linking with Boost?

Boost IRIX build problems
by Jeroen Akershoek 24 Nov '05

24 Nov '05

Hello, I'm trying to build boost on our SGI Onyx4 and am running into some problems. I've tried looking up some documentation for configuring the build-system a bit better, but couldn't find much. I don't have the time to dig into it and find it out myself, especially since building boost isn't my ultimate goal for this exercise, so I'm hoping you can help me out here I'm getting (a lot of occurances of) three errors throughout the build: 1) the indicated type is incomplete std::basic_istream<charT> m_is; // stream for parsing numbers. Not sure about this one. Missing include somewhere or maybe SGIs STL is f00bar 2) The indicated enumeration value is out of "int" range. enum npos_type { npos = (size_type)-1 }; I assume it's the same problem as with IBMCPP. Don't know if MIPSpro can have 64-bits enums. 3) Threading is disabled: _SGI_MP_SOURCE is undefined If somebody could help me out with these, I'd be very grateful. My environment is IRIX 6.5.27 with MIPSpro 7.41, bjam 3.1.11 and I'm trying boost 1.33.0. I've modified the tools/build/v1/mipspro-tool.jam to use -64 and -mips4 as default. Probably not the way to do it, but I couldn't find the "proper" way within decent time Kind regards, Jeroen -- Jeroen Akershoek SARA - High Performance Computing & Visualization dep. tel: +31 20 5923000 fax: +31 20 6683167 Draco dormiens nunquam titillandus

Complaint about Current Boost Build System
by Wu Yinghui, Freddie 24 Nov '05

24 Nov '05

Hi all, Sorry for this e-mail, since it is more of a complaint. But I do feel the urge to raise this problem to the community so that some solution could be derived soon. The current build system (1.33/34 from CVS) creates subdirectories for each variant/ subvariant specified in the BUILD environment. When more user customizations are specified, the consequence of this is very deep directory structures. Nonetheless, some OSes imposes stringent limits on how long a path can go (e.g., Win2k/XP limits a path name to be 259 characters long maximum). There causes big problem with the building system when error can occur from nowhere in Boost source code itself. This constraint effectively limits how much customization a user can make (e.g., I had to remove some additional optimization/ tuning parameters for subvariants, and SUBST'ed the Boost directory in order to reduce the path name length). So my question is, why can we not be smarter in this to derive alternatives to make the directory structure shallower (or, simply reduce the length of the names of each subvariant directory)? Sorry again if this sound too demanding, but I do consider it an important usability limitation of the current Boost build system.
