It's a POD type. So the point is indeed moot. Thanks.

This makes no sense. Your test program does not refer to the itest facilities.
There is single testing tool involved as well. Something seriously screwing up
the stack.
Can you try to go step by step in the debugger? Can you also try build UTF as

Re: [Boost-users] [Uuid] Portable binary serialization.

2010-03-12T22:28:27Z

I've been a strong advocate of making UUID a POD, in which case the
fallback is perfectly fine.
I don't remember what Andy decided, but check whether the version
you're using is a POD before worrying.

[Boost-users] [Uuid] Portable binary serialization.

2010-03-12T22:16:23Z

I'm interested in using the portable binary serialization code in
[serialization]/example directory with Boost.Uuid. I've noticed that
there's a fall back template function for unrecognized types in
portable_binary_iarchive.hpp:
101 // default fall through for any types not specified here

[Boost-users] BOOST_STATIC_CONST

Hi all,
I am currently having problem with a static const class member (in a header
only project):
// type.hpp
template< typename Property >
struct property_base
{
typedef Property type;
struct some_type : property_base< uint32_t >
{
BOOST_STATIC_CONSTANT( type, first_value = 1 );
BOOST_STATIC_CONSTANT( type, second_value = 2 );

Documentation is still in progress, we're rewriting everything to quickbook
format. Meanwhile, please find attached your test case, hopefully it makes
it a bit clearer.
If you run into further difficulty, please let me know.
Cheers,

Re: [Boost-users] boost.units converting double tp SI prefix

2010-03-12T19:22:33Z

There is not such a facility. There will soon be support for
printing things like 1.0 km instead of 1000 m, but formatting
of raw numbers is somewhat beyond the scope of the library.

[Boost-users] strange "fatal errors" with Boost.Test

2010-03-12T18:54:31Z

Dear boost experts,
while adding regression tests to my project I experience very strange
errors. I am using boost 1.40 and g++ 4.4 as packaged in Debian
testing.
The problem is that a very simple test suite, one which does almost
nothing, produces the following runtime error:
cwg@argo:/tmp/lg-bug$ ./test_all

[Boost-users] boost.units converting double tp SI prefix

2010-03-12T18:00:58Z

Hi,
is there a way to use boost.units to convert a double automatically to a
SI unit prefix, e.g. 10e-3 to 10m or 10e3 to 10k ?? The value isn't know
at compile time, so the decision has to be done on runtime.
Thanks,
Olaf

Sure, I can help with the one without the -v1 suffix. The regressions tests
should work for 98%, the examples however aren't ported yet to the newer
bindings structure. One of the major changes in the newer bindings is that
if you would like to use atlas, it's still blas, so
bindings::atlas::gemm( ... )

Hello,
I try to install the numerical bindings for my boost, but I can't

the examples. I had installed and compilde the Atlas Lib 3.9.23 with
Lapack support and the Boost 1.42 with MPI Support under OS X Leo.
I take a look at [link]

Re: [Boost-users] storing pointers in a std::map

2010-03-12T16:13:39Z

Thanks. I presume it would be better in implementing a map that can hold
left = std::string, right = "any" but only pointers to objects to have a
boost::map_ptr<std::string> than a std::map<std::string, boost::any>.

[Boost-users] matrix iterator each element

2010-03-12T10:23:49Z

Hello,
I have very large matrices (not sparse), where I have to change
each element. From the documentation I used the example
with which two for-loops.
I use for vectors:
blas::vector<T> l_vec = p_vec;
BOOST_FOREACH( T& i, l_vec)
i = std::pow(i, p_exponent);
Is there any way to process each element in
