"cross-running" boost tests
by Gottlob Frege 23 Nov '12

23 Nov '12

I've managed to cross-compile boost for BlackBerry10 devices. (Side-note: there is very little docs on cross compiling) Now, how would I go about "cross-running" the boost tests? In particular, can I hook into the unit-test and/or run rules of Boost.Build? Given a command line, I can load and run it on device and then retrieve the results, I just need to know where to hook in. Tony

Can you share how you succeeded a cross compiling the tests, I didn't have luck. - Sent via iPhone -----Original Message----- From: Gottlob Frege [gottlobfrege(a)gmail.com<mailto:gottlobfrege@gmail.com>] Sent: Thursday, November 22, 2012 12:28 PM Pacific Standard Time To: boost-users(a)lists.boost.org Subject: Re: [Boost-users] "cross-running" boost tests That is along the right track. But I don't want to have to do that for every boost test file. This isn't for my own tests, I want to run the boost tests. I sort of need a global launcher that I can hook into.

I guess you should see how Boost.Build could support this. Best, Vicente Right. That's kind of what I'm asking. Does Boost.Build support this already? Is there a way to hook into 'run'? I don't find Boost.Build (or docs) easy to use/understand, so my poking around at it didn't find anything, but I could have easily missed it.

Then serializing and > other operations would probably be trivial. Shalom Another option would be an intrusive list -- http://www.boost.org/doc/libs/1_52_0/doc/html/intrusive.html . The serialization library in Boost doesn't provide support for intrusive containers, but the C++ Middleware Writer -- http://webEbenezer.net has support for intrusive list and rbtree. If you use std::list, the C++ Middleware Writer has some advantages -- http://webEbenezer.net/comparison.html over the serialization library in Boost. (There are serialization and deserialization tests with std::list there.) -- Brian Ebenezer Enterprises -- so far G-d has helped us. http://webEbenezer.net (651) 251-9384

[mpl] How to use not_ with has_trivial_destructor metafunction
by Christian Henning 22 Nov '12

22 Nov '12

Hi there, I have troubles compiling the following code with Visual C++ 2010 and boost 1.52. #include <boost/mpl/not.hpp> #include <boost/type_traits/has_trivial_destructor.hpp> #include <boost/utility/enable_if.hpp> template <typename T> void foo( typename boost::enable_if< boost::mpl::not_< boost::has_trivial_destructor< T > > >::type* /*ptr*/ = 0 ) { int i = 9; } int main(int argc, char* argv[]) { foo< int >(); return 0; } The error I'm getting is: error C2770: invalid explicit template argument(s) for 'void foo(boost::enable_if<boost::mpl::not_<boost::has_trivial_destructor<T>>>::type *)' Can someone see what the problem might be? Thanks, Christian

[Range & c++0x Lambdas] Can this be done?
by Robert Jones 22 Nov '12

22 Nov '12

Can the last line, labelled NOT Ok, be made to work? I think the lambda does not publish its result as a bind does, so I suspect it's hopeless. Any thoughts? Thx, Rob. #include <boost/range/adaptor/transformed.hpp> #include <boost/range/algorithm_ext/push_back.hpp> #include <boost/bind.hpp> #include <vector> #include <algorithm> struct S { int i; }; void f( std::vector<int> & out, std::vector<S> & in ) { using boost::adaptors::transformed; // Ok std::transform( in.begin( ), in.end( ), std::back_inserter( out ), bind( & S::i, _1 ) ); // Ok boost::range::push_back( out, in | transformed( bind( & S::i, _1 ) ) ); // Ok std::transform( in.begin( ), in.end( ), std::back_inserter( out ), []( S & s ) { return s.i; } ); // NOT Ok boost::range::push_back( out, in | transformed( []( S & s ) { return s.i; } ) ); }

list serialization with boost
by Olivier Austina 22 Nov '12

22 Nov '12

Hello, I am a newbie of boost and I want to use it. I would like to serialize a list. The list is defined with the following data type: typedef struct person { char *name; char *first_name; struct person *next; } person; person *list_person; I have the list built from this structure and I want to serialize it on the hard disk. -- Regards Austina

[Intrusive] unordered_set and thread safety
by Alexandre Hamez 22 Nov '12

22 Nov '12

Hello, I'm currently using intrusive:: unordered_set in a single threaded application. But now, I need to switch to a multi threaded application. As such, the unordered_set must be protected. I don't want to block the whole table with a single mutex. Thus, it would be fine to have a lock per bucket. Furthermore, intrusive:: unordered_set provides a bucket_traits mechanism to enable some customization. So, my question: is it possible to use bucket_traits to have a lock per bucket? Thank you! -- Alexandre Hamez

Errors compiling with Boost
by Amos Anderson 21 Nov '12

21 Nov '12

Hello -- I'm having trouble compiling our code on redhat gcc 4.4.6 (full specs below). There are a lot of errors in the output, but paring down the list a bit, some examples are pasted below. This exact same code successfully compiles on several OSX compilers, as well as redhat gcc 4.1.2. I posted this to Boost.Build, and someone informed me I had posted to the wrong list. This person mentioned that: > OSX has gcc-4.2 or clang 3.1 for 10.8. > > The gcc project has done some cleanups of standard library code, eliminating > some implicit dependencies. So you might need to explicitly include the now > missing headers. > > Yours, > > Jürgen Does anybody have any suggestions for which headers I might be missing? I do not have direct access to the machine with these compile errors, so it's hard for me to just fiddle with my code. thanks for any advice!

SVN access problem
by Simon West 20 Nov '12

20 Nov '12

Hi, I am being asked for a username and password when attempting to check out Boost anonymously using the following command: $ svn co http://svn.boost.org/svn/boost/trunk boost-trunk This command was copy-pasted directly from the instructions for anonymous read-only access described at https://svn.boost.org/trac/boost/wiki/BoostSubversion. This is holding up my progress in creating a patch - can anyone help? Thanks, Simon.

[enable_if] Compile Time Member Overloading

Hi there, can someone tell me why the following doesn't compile with VS2010 SP1? #include <boost/mpl/and.hpp> #include <boost/type_traits/is_same.hpp> #include <boost/utility/enable_if.hpp> using namespace boost; struct foo { void bla() { read_data_24<int, int>(); } template< typename T1 , typename T2 > void read_data_24( typename enable_if< mpl::and_< mpl::true_ , mpl::bool_< is_same< T1, T2 >::type::value > > >::type* /* ptr */ = 0 ) { int i = 9; } }; int main(int argc, char* argv[]) { return 0; } I get the error: 1>gil_test_vc10.cpp(25): error C2039: 'type' : is not a member of 'boost::enable_if<Cond>' 1> with 1> [ 1> Cond=boost::mpl::and_<boost::mpl::true_,boost::mpl::bool_<false>> 1> ] I tried a couple of hours to have make is happen but I don't get it.
