Fwd: cannot find lboost_thread -problem
by Väisänen Teemu 03 Jan '06

03 Jan '06

Hi all. It seems I have tried to send my messages to wrong mailing lists. Sorry about extra work. I need Boost and lboost_thread to compile Open Diameter. When compiling Open Diameter, I get message /usr/bin/ld: cannot find -lboost_thread I can not find lboost_thread with slocate after compiling Boost 1.33.1, so presumable reason is that I haven't used bjam with right options. Do I need to add libraries using --with-<lib> option to get lboost_thread? If yes, which library has it? Do I also need to use -th option? If I want to use boost rpm's (1.32.0) that came with Linux distribution and is installed already, what should I do to get lboost_thread? Thank you for any answers and help! -Teemu Väisänen

Problems cross compiling to ARM
by James Hughes 03 Jan '06

03 Jan '06

Hello all, I am cross compiling the boost libs to the PXA270 arm processor running Linux, using GCC 3.4.3 (iwmmxt_le-g++ et al from Montavista) Whilst a lot of libs do seem to build correctly, I get a number of other errors. Here is a typical example which comes up a lot..... /home/jhughes/boost_1_33_1/boost/spirit/core/primitives/numerics.hpp:120: error: declaration of `template<class ScannerT> struct boost::spirit::sign_parser::result' /home/jhughes/boost_1_33_1/boost/spirit/core/parser.hpp:123: error: conflicts with previous declaration `template<class ScannerT> struct boost::spirit::parser<boost::spirit::sign_parser>::result' In file included from /home/jhughes/boost_1_33_1/libs/serialization/build/../src/basic_xml_grammar .ipp:22, from /home/jhughes/boost_1_33_1/libs/serialization/build/../src/xml_wgrammar.cpp: 243 In fact most of the errors seem to be in the grammer area. The command I use to do the build is ... bjam "-sGCC_ROOT_DIRECTORY=/opt/montavista/mobilinux/devkit/arm/iwmmxt_le" "-sGCC=iwmmxt_le-gcc" "-sGXX=iwmmxt_le-g++" stage In addition, I do not seem to get any files copied to the include folder when doing a install build (/usr/local/lib has lots of my built boost libs, /usr/local/include is empty). I would expect to see files in there - am I correct in that expectation? Anyone any ideas? James

Dear Robert, The boost library I use is from direct includes from Fedora Core 4. I think they might have done a good job to make it work before they distribute on FC4. I built a local boost library per your suggestion, however, the same errors come up. Any More suggestion? Like any small sample code can be built successfully on your system if it is a linux? Thanks. Feng

Merrill, I tried to change the include files order as you suggested, but it does not work. Any more suggestions? Feng

Boost.Serialization // Basic Usage Problem for your help!
by Feng Wang 03 Jan '06

03 Jan '06

Dear All, I got a trouble with boost::serialization library and need your help. 1) I am working with FC4 on my laptop. GCC 4.0.2 is known handle this library pretty well according to yesterdays's report. http://boost.sourceforge.net/regression-logs/cs-Linux.html 2) try to test the basic sample obtained on webpage posted by Jeff Cogswell: #include <fstream> #include <iostream> //#include <boost/serialization/base_object.hpp> #include <boost/archive/text_oarchive.hpp> #include <boost/archive/detail/basic_iarchive.hpp> #include <boost/archive/text_iarchive.hpp> #include <boost/serialization/utility.hpp> #include <boost/serialization/access.hpp> using namespace std; class Vertex { private: friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int version) { ar & x; ar & y; } double x; double y; public: Vertex() {} // Serialization requires a default constructor Vertex(double newX, double newY) : x(newX), y(newY) {} double getX() const { return x; } double getY() const { return y; } void dump() { cout << x << " " << y << endl; } }; int main() { Vertex v1(1.5, 2.5); std::ofstream ofs("myfile.vtx"); boost::archive::text_oarchive oa(ofs); oa << v1; ofs.close(); return 0; } 3) try to compile and link it by the following command: g++ -lboost_serialization testoa.cpp -otestoa and got a bunch of errors. 4) The errors looks as this:

Feng, I don't have the expertise to decode the full list of errors. However, I do know that there is an ordering dependency that requires all archive include files come before any serialization include files. So, try rearranging your #includes to put archive includes first and see what happens. Merrill

True, but it's not the BOOST_AUTO_TEST_MAIN that's causing the problem, or that's being included in more than one file. > Worse, that also means that other headers that pay attention to > that macro can't be in a common header, otherwise the One Definition Rule > would be broken. If you have two translation units with an anonymous namespace, they may appear to be defining the same thing twice. But the C++ standard says it is not the same thing, since each anonymous namespace is distinct. So the definitions occur in different namespaces.

[serialization] assertion in basic_binary_oprimitive::save_binary() revisited
by Austin Bingham 02 Jan '06

02 Jan '06

A while ago I brought up what I considered (and still consider) to be a serious problem in basic_binary_oprimitive::save_binary(). The problem is the assert at the end of the function: assert(os.good()); There are a number of reasons why doing this is a bad idea, but the discussion on this issue was dropped flat on the floor. Is there any possibility of discussing alternatives to this assertion? At the very least, can I get an explanation of why an assert is correct to which counter-arguments might be considered? -- Austin Bingham

boost::spirit, comment_p("//")

Hello Boost users. I'd like to know if anyone was solving the following problem. I tried to use comment_p("//") in this way: rule_t r = *(anychar_p-comment_p("//")) % comment_p("//")[push_back_a(v)] ; This works for me except this case: C++ code: <snip> else if (szMethodName == "the test //") open(tCallParams, tAction); <snip> Problem is caused by the string "the test //". Then the source is parsed in the wrong way because //") open(tCallParams, tAction); is assumed as comment. I think I should select an allowed segment where // is valid.
