Re: [Boost-users] [Test] Is It Possible to Put Test Cases in DLL?

Hi Edwin, Thanks for your pointer. But how this small test framework is supposed to work out? The fact is that I've been using Boost.Test mostly with its auto test case capability (I don't want to have to write code to register my test cases one by one in general, unless that's the last resort). Therefore, I'm not very familiar with how such mechanism can work out by writing some test framework of my own... Would you mind to shed some more light on this?

boost::numeric::ublas matrix iterators
by Ed Johnson 01 Jun '06

01 Jun '06

Hi, I read through the Ublas documentation but did not see any examples with the iterator1 and iterator2 being used with a matrix. I am having trouble working with them. Does anyone know how to recreate this example using the iterators? http://www.boost.org/libs/numeric/ublas/doc/matrix.htm int main () { using namespace boost::numeric::ublas; matrix<double> m (3, 3); for (unsigned i = 0; i < m.size1 (); ++ i) for (unsigned j = 0; j < m.size2 (); ++ j) m (i, j) = 3 * i + j; std::cout << m << std::endl; } Many thanks, Ed Johnson

Using Boost.Build to link to boost libs
by Pierre THIERRY 01 Jun '06

01 Jun '06

Hi, I've read a great part of Boost.Build's documenation and taken a look i all the rest of it, but I don't quite understand of to use it to build to boost libs and arbitrary libs in general. If I have main.cpp that should be compiled to main, and uses boost::program_options, what should the Jamfile be? If it was any other lib, like POSIX threads or libbzip2, what would it be? That may sound quite simple, but I'm not sure it's clearly in the doc. :-/ Desperately, Nowhere man -- nowhere.man(a)levallois.eu.org OpenPGP 0xD9D50D8A

Pb compiling serialization on linux
by Thomas DAVID 01 Jun '06

01 Jun '06

Hi all, i've posted some time ago about a problem about how to serialize valarray with boost. The answer was to use the CVS version. But I have errors when i try to compile it. I downloaded the .rpm version of bjam, and installed it with alien and dpkg (i use Ubuntu). I used this command to launch the compilation : bjam --with-serialization I'm using : g++ (GCC) 3.4.6 (Ubuntu 3.4.6-1ubuntu2) and GNU ld version 2.16.91 2006011 I have many erros like this : `.L454' referenced in section `.rodata' of bin/boost/libs/serialization/build/libboost_serialization.so/gcc/debug/shared-linkable-true/array_binary_oarchive.o: defined in discarded section `.gnu.linkonce.t._ZNK5boost7archive17archive_exception4whatEv' of bin/boost/libs/serialization/build/libboost_serialization.so/gcc/debug/shared-linkable-true/array_binary_oarchive.o and collect2: ld a retourné 1 code d'état d'exécution (ld returned code 1) and at the end : ln -fs "libboost_serialization-gcc-mt-1_35.so.1.35.0" "bin/boost/libs/serialization/build/libboost_serialization.so/gcc/release/shared-linkable-true/threading-multi/libboost_serialization-gcc-mt-1_35.so" ...failed gcc-Link-action bin/boost/libs/serialization/build/libboost_serialization.so/gcc/release/shared-linkable-true/threading-multi/libboost_serialization-gcc-mt-1_35.so... ...skipped <@boost!libs!serialization!build/libboost_wserialization.so/gcc/debug/shared-linkable-true>libboost_wserialization-gcc-d-1_35.so for lack of <@boost!libs!serialization!build/libboost_serialization.so/gcc/debug/shared-linkable-true>libboost_serialization-gcc-d-1_35.so... ...skipped <@boost!libs!serialization!build/libboost_wserialization.so/gcc/debug/shared-linkable-true/threading-multi>libboost_wserialization-gcc-mt-d-1_35.so for lack of <@boost!libs!serialization!build/libboost_serialization.so/gcc/debug/shared-linkable-true/threading-multi>libboost_serialization-gcc-mt-d-1_35.so... ...skipped <@boost!libs!serialization!build/libboost_wserialization.so/gcc/release/shared-linkable-true>libboost_wserialization-gcc-1_35.so for lack of <@boost!libs!serialization!build/libboost_serialization.so/gcc/release/shared-linkable-true>libboost_serialization-gcc-1_35.so... ...skipped <@boost!libs!serialization!build/libboost_wserialization.so/gcc/release/shared-linkable-true/threading-multi>libboost_wserialization-gcc-mt-1_35.so for lack of <@boost!libs!serialization!build/libboost_serialization.so/gcc/release/shared-linkable-true/threading-multi>libboost_serialization-gcc-mt-1_35.so... ...failed updating 4 targets... ...skipped 4 targets...

With the latest CVS, test\preprocessor.cpp no longer compiles. The first two errors are: macro BOOST_PARAMETER_FOR_EACH_pred_aux3 requires 3 arguments, but only 2 given macro BOOST_PP_SPLIT_0 requires 2 arguments, but only 1 given All of my programs that use BOOST_PARAMETER_FUNCTION et al. are failing due to these errors.

boost::bind with const parameter
by Alain Cormier 01 Jun '06

01 Jun '06

Hi group! I try to call in a for_each a member function that take a parameter by value AND const. I know we do not need to do things like that, but I am using code from an other team and I don't want to change it if I don't need. It results with this error : D:\ENG-AC\working\tests\test_ParamConst_vs_boostBind\test\test.cpp(35) : error C2665: 'bind' : none of the 2 overloads can convert parameter 1 from type 'int (__thiscall test_class::*)(const int) const' Here a little program that reproduce de behavior : #include <algorithm> #include <vector> #include "boost/bind.hpp" class test_class { public: test_class(int value) : m_value(value){} ~test_class(){} int fct_param_const(const int value) const {return m_value + value;} int fct_param_ref_const(const int& value) const {return m_value + value;} int fct_param(int value) const {return m_value + value;} private: int m_value; }; int main(int argc, char* argv[]) { std::vector<int> all_values(5); std::generate(all_values.begin(), all_values.end(), &rand); test_class doTest(28); std::for_each(all_values.begin(), all_values.end(), boost::bind(&test_class::fct_param, doTest, _1)); std::for_each(all_values.begin(), all_values.end(), boost::bind(&test_class::fct_param_ref_const, doTest, _1)); // DOESN'T WORK : because of the parameter by value and const??? //std::for_each(all_values.begin(), all_values.end(), boost::bind(&test_class::fct_param_const, doTest, _1)); return 0; } Is this a correct behavior from boost::bind? Does the only solution is to remove the const from our function? We have so much difficulty to stay const-correct, I do not want to send a signal to our team that const isn't good (but maybe too much const isn't good :D). Anyway, what do you suggest? By the way. I am using VC6 (SP5) under Win2000 and boost 1.33.1. Regards, -- Alain Cormier alain.work(a)gmail.com

[Test] Is It Possible to Put Test Cases in DLL?
by Wu Yinghui, Freddie 31 May '06

31 May '06

Dear all, I remember seeing similar topic some time earlier, but I failed to find the information I need. So if this question has been answer before, please kindly point me to the correct resource. TIA! Basically, I goal is to build a bunch of unit test cases into a few DLLs, and be able to run them by loading the DLLs into my test executable (either automatic or using LoadLibrary is fine with me). I'm using the auto registration facility now to create and register the test suites and cases. And I'm running on MSVC 7.1 on Windows XP SP2 now. Any pointer will be greatly appreciated.

Re: [Boost-users] [BGL] Updating to CVS version, typedef ... Graph not working?!
by dave＠boost-consulting.com 31 May '06

I think there's probably a better way: put all the concepts in a nested namespace of boost and then add a using-directive to expose them in boost... Although I'd really like to see the whole test program first, because it's not obvious where/how the collision occurs. -----Original Message----- From: dgregor(a)osl.iu.edu Subj: Re: [Boost-users] [BGL] Updating to CVS version,typedef ...

[snip] > Can someone explain to me what's happening here? This looks like fallout from recent changes to the concept checking library. There is now a template called "Graph" in namespace boost, and we find that as well as your "Graph" typedef. This might force us to go back to the "Concept" suffix on concept checking templates, if this problem affects many compilers :( Doug -- Dave Abrahams Boost Consulting http://www.boost-consulting.com

[Graph] BGL python bindings documentation
by John Reid 31 May '06

31 May '06

Hi, Can anyone point me in the direction of some documentation of the python bindings for the BGL? I know this is no longer part of boost. Should I be asking some other list? The documentation at http://www.osl.iu.edu/~dgregor/bgl-python/#example and http://www.osl.iu.edu/~dgregor/bgl-python/reference/boost.graph.html is helpful but far from complete. What happened to the more user friendly documentation that came with boost_1_33_1? How stable is the interface? Is the library actively maintained? After all that I'd like to say I have found the bindings very useful just a little hard to work with at first. Thanks, John.
