Why does boost::locale::generator fail for some locale codes?
by Adrián Chaves Fernández (Gallaecio) 15 May '12

15 May '12

I am using boost::locale::generator with its default backend (ICU I assume) to generate an std::locale. But for some reason, when I pass certain locale codes to the generator, it fails and the application execution is interrupted with the following output messages: terminate called after throwing an instance of 'boost::locale::conv::conversion_error' what(): Conversion failed Abortado I have tested the following values: * gl — FAILS * gl_ES — FAILS * gl_ES.utf8 — Works * en — Works * en_US — Works * en_US.utf8 — Works Installed locales should not be the issue: [user@localhost build]$ locale -a C en_US en_US.iso88591 en_US.utf8 galego galician gl_ES gl_ES@euro gl_ES.iso88591 gl_ES.iso885915@euro gl_ES.utf8 POSIX So why might this be happening?

Boost/Asio short read error
by Marcin Głogowski 15 May '12

15 May '12

Hi, I have problem with Boost/asio - sometimes server returns "short read" error. I'm using client/server from the examples. Please write me - is it a bug or just wrong implemented example because the error occurs not every time. How to protect my application against the error?

boost::asio The semaphore timeout period has expired
by Markus Bonk 15 May '12

Hi, I am getting a timeout "The semaphore timeout period has expired" from async_read_some which I do not want. What is causing it - ok, it could be that I am not receiving anything and how do I configure it? Markus

communicate with GSM MODEM
by Evaggelos Tsampazis 15 May '12

15 May '12

Hi Everyone! I would like to ask if someone knows how to use in detail the serial_port() mechanism. I want to create an API application where I will send SMS messages from the pc instead of the mobile phone/gsm modem. Of course, the mobile phone will be connected to the PC from a com or tty serial port. Despite that, I would also like to receieve the inbox from the mobile device. By other words, I need a way to send AT commands to my gsm device and then after receieve the answer. How can that be made easy? Thanks Evaggelos

Using BoostTest to run unit tests multiple times without quitting test runner
by Pankaj 15 May '12

15 May '12

I want to use Boost Test to run unit tests multiple times without quitting the test runner. Here is the pseudo-code to demonstrate what I want to do: void main() { for(int i = 0; i < 10; ++i) { char *arguments[] ={ "MyApplication.exe", "--detect_memory_leak=0" }; boost::unit_test::unit_test_main( &init_function, 2, arguments); } } The first time unit_test_main is called, all the boost tests run fine but in the second iteration, boost test throws an exception. I looked at the internal code and found that framework is initialized everytime unit_test_main is called and if framework is already initialized, boost test doesn't like initializing framework again. Please let me know if there is any way to run units test multiple times without quitting test runner. -- View this message in context: http://boost.2283326.n4.nabble.com/Using-BoostTest-to-run-unit-tests-multip… Sent from the Boost - Users mailing list archive at Nabble.com.

boost::bind and Motif
by Sven Bauhan 14 May '12

14 May '12

Hi, I just tried to use boost::bind to create a function pointer from an object method to define it as a Motif callback function: class AnimationController { public: void timerCB( XtPointer, XtIntervalId* ); void startTimer() { this->mTimeout = XtAppAddTimeOut( this->mAppContext, ANIMATION_TIMESTEP, boost::bind( &AnimationController::timerCB, this ), NULL ); } ... }; For the definition of the Motif function: XtIntervalId XtAppAddTimeOut( XtAppContext /* app_context */, unsigned long /* interval */, XtTimerCallbackProc /* proc */, XtPointer /* closure */ ); with typedef void (*XtTimerCallbackProc)( XtPointer /* closure */, XtIntervalId* /* id */ ); But I get the following error: ../AnimationController.cpp: In member function 'void geo::AnimationController::startTimer()': ../AnimationController.cpp:193: error: cannot convert 'boost::_bi::bind_t<void (&)(void*, XtIntervalId*), boost::_mfi::dm<void ()(void*, XtIntervalId*), geo::AnimationController>, boost::_bi::list1<boost::_bi::value<geo::AnimationController*> > >' to 'void (*)(void*, XtIntervalId*)' for argument '3' to 'XtIntervalId XtAppAddTimeOut(_XtAppStruct*, long unsigned int, void (*)(void*, XtIntervalId*), void*)' Can someone explain, what I did wrong? Thanks, Sven

[Intrusive] Cleaning up trailing white space
by Brian Wood 14 May '12

>From what I can tell a lot of Boost libraries would benefit from this, but in particular I want this for the Intrusive library. It helps to improve compile times and reduce the space needed by Boost. I used grep " $" * to help with that here. Shalom, Brian Wood Ebenezer Enterprises http://webEbenezer.net

(GCC) 4.6.3 and boost_1_47_0 lockfree issue

Hi All, I am using boost_1_47_0 and (GCC) 4.6.3. The C++ application on linux complains on the following in linking. boost_1_47_0/boost/lockfree/detail/freelist.hpp:124: undefined reference to `std::atomic<boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node> >::operator boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node>() const' /boost_1_47_0/boost/lockfree/detail/freelist.hpp:124: undefined reference to `std::atomic<boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node> >::operator boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node>() const' collect2: ld returned 1 exit status I looked into http://tim.klingt.org/code/projects/boost-lockfree/repository/revisions/423… and dowloaded lockfree changed files. But the issue still exists. boost_1_47_0/boost/lockfree/detail/freelist.hpp:117: undefined reference to `std::atomic<boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node> >::compare_exchange_weak(boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node>&, boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node>, std::memory_order)' boost_1_47_0/boost/lockfree/detail/freelist.hpp:87: undefined reference to `std::atomic<boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node> >::load(std::memory_order) const' boost_1_47_0/boost/lockfree/detail/freelist.hpp:124: undefined reference to `std::atomic<boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node> >::operator boost::lockfree::detail::tagged_ptr<boost::lockfree::detail::freelist_node>() const' Any idea on this ?
