Re: [Test] main for BOOST_TEST_DYN_LINK with manualregistration

Rhys Ulerich — 2012-05-25T21:49:38

I'm dumb.  Naming the init_unit_test() method the same thing in either
case simplifies main().  Sorry for the line noise.

Re: [Test] main for BOOST_TEST_DYN_LINK with manualregistration

Rhys Ulerich — 2012-05-25T21:39:50

This appears to work but I would certainly appreciate a prettier solution...

#ifdef BOOST_TEST_ALTERNATIVE_INIT_API
bool init_unit_test()                   {
#else
::boost::unit_test::test_suite*
init_unit_test_suite( int, char* [] )   {
#endif

  // Register some stuff

#ifdef BOOST_TEST_ALTERNATIVE_INIT_API
    return true;
}
#else
    return 0;
}
#endif

int main( int argc, char* argv[] )
{
#ifdef BOOST_TEST_ALTERNATIVE_INIT_API
    return ::boost::unit_test::unit_test_main( &init_unit_test, argc, argv );
#else
    return ::boost::unit_test::unit_test_main( &init_unit_test_suite,
argc, argv );
#endif
}

Regardless of the prettiness of the solution, this would be helpful to
include in the manual at
http://www.boost.org/doc/libs/1_49_0/libs/test/doc/html/utf/user-guide/test-organization/manual-test-suite.html

[Test] main for BOOST_TEST_DYN_LINK with manualregistration

Rhys Ulerich — 2012-05-25T21:28:07

What from example 15 from the Boost.Test "Manually registered test
suites" documentation[1] needs to change if instead of
   #include <boost/test/included/unit_test.hpp>
one used
   #define BOOST_TEST_DYN_LINK
   #include <boost/test/unit_test.hpp>
?

the unit_test_main, but I'm at a loss for what it would look like...
I don't think I'm running afoul of BOOST_TEST_ALTERNATIVE_INIT_API
from reading <boost/test/unit_test.hpp> where the main() definition
cares nothing about that #define, but I could be wrong.

Help or a known-good example much appreciated,
Rhys

Re: "invalid signature" inboost::archive::binary_iarchive

Robert Ramey — 2012-05-25T22:02:33

binary archives are not portable across architectures.  Specifically
it is not possble to create a binary archive with 32 bit code and
and read that archive with 64 bit code.  You'll have to write
your achive to some portable format such as a text archive.
Then you can load it on any platform.

"invalid signature" in boost::archive::binary_iarchive

Ibrahim Beicker — 2012-05-25T18:44:07

I had to port a multi-process application to 64 bits and I rely on boost
serialization to send messages, that are maps of key-values, into Microsoft
queues to the other modules. It works just fine into 32 bits but when I run
it in 64 the constructor throws an "invalid signature" exception

void Message::fromBinary( const std::string& data )
{
  std::stringstream ss;
  ss << data;
  boost::archive::binary_iarchive ia(ss); //exception here

  ia >> *this;
}

I managed to debug into basic_binary_iarchive.ipp and this 'if' < at > line 72
fails

if(file_signature != BOOST_ARCHIVE_SIGNATURE())

boost::serialization::throw_exception(archive_exception(archive_exception::invalid_signature));

inside this file I have no debug symbols so I don't know the values of
'file_signature' and 'BOOST_ARCHIVE_SIGNATURE' or where
BOOST_ARCHIVE_SIGNATURE is defined.

Some additional information: the modules are all running on the same
machine, on windows 7 64-bits, and  compiled by visual studio 2010 x64
including static boost librarie

Re: [Geometry] spatial linestring access along line

Thanks Barend,

the function you mentioned is just what I needed.
I have implemented it on my own. Sadly, only the brute force approach
using for_each_segment and adding up the length travelled.

Great lib nonetheless.

You might try inserting that, and see if that fixes the problem.

[container] Compilation failure with clang 3.1

Hello,

When compiling Boost.Container, clang 3.1 (stable release, Mac OS X 10.7.4) 
fails:
 

However gcc 4.7 has no problem with it. Does anyone has experienced the 
same thing and possibly found a workaround?

Thank you!

Re: [multi_index] movable only types

Joaquín M LópezMuñoz — 2012-05-25T08:28:40


Hi Szymon,

Boost.MultiIndex definitely needs to be updated so as to
be conformant with new requiremts for C++11 containers,
including (but not only) move support. The sad reality is
that the time I can devote to this task is vanishingly small.
I could save some time for this in the future, but can't
really commit to a date yet.

Of course, if someone is bold enough to initiate the work
herself and proposes a patch, I'll be more than willing to help
with the effort.

Re: [msm] Two identical orthogonal regions?

Christophe Henry — 2012-05-24T20:23:08


Hi,

for MSM they just need to be different types. You can define structs 
inheriting from base states, you can templatize them with an int parameter, 
you can even define a submachine which you inherit from and paste 2 
instances, one in each region.

Though I didn't try it since the times of MSM v1, something like the 
following should work (assuming Functor Front-end):

struct SubFront : msm::front_state_machine_def<SubFront>{...};
typedef msm::back::state_machine<SubFront> SubHelper;

template <int index>
struct Sub: public SubHelper{};

// Outer machine
// we have only the submachines in the regions so that it is easier to 
duplicate
typedef mpl::vector<Sub<0>, Sub<1> > initial_state;
// excerpt from transition table
Row<Sub<0>,...>,
Row<Sub<1>,...>

HTH,
Christophe

[msm] Two identical orthogonal regions?

Aurelian Melinte — 2012-05-24T18:25:33

Hi,

I am trying to put two identical orthogonal regions in a state machine 
(each region would model a "channel" and I can have multiple such 
channels).

One way I can think of is duplicating the states through typedefs and 
duplicating entries in the transition table.

Is there a way to avoid this duplication?

a.

Re: Iterator concept checking

Jeffrey Lee Hellrung, Jr. — 2012-05-24T17:11:16


Hmmm...the below code (with a slight modification) compiles for me on
MSVC9, Boost 1.49.0.



I don't know where the following concept checking classes are defined, but
from [1], it appears you should be using
boost_concepts::ForwardTraversalConcept, etc. (badly named, IMHO, but
that's what I'm finding in the documentation).



(Also, could you please use plain formatting in your emails? It makes it
easier to reply inline and easier to read across a wide variety of media.
Thanks.)

Iterator concept checking

McNamara, Nate — 2012-05-24T15:39:41

I'm trying to learn to use BOOST_CONCEPT_CHECK for custom iterators,
ranges, and containers.  I've built a simple linked list class with an
iterator (and const_iterator) that, as far as I can tell, satisfies the
forward traversal iterator requirements.  However, g++ gives the
following errors:
