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

(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.

Re: [Boost-users] [mpl] cross product and gcc specific compiler error

Hi, I grabbed an mpl cross product implementation (product_view) of this mailing list. It works fine in MSVC but fails in gcc: // typedef boost::mpl::vector<decimal32, decimal64, decimal128> DecimalTypes; // Original typedef boost::mpl::vector<float, double, long double> DecimalTypes; // for demonstration typedef boost::mpl::vector<int, unsigned int, long, unsigned long, long long, unsigned long long> IntegralTypes; typedef product_view<boost::mpl::vector<DecimalTypes, IntegralTypes> > EachDecimalWithEachIntegralT; BOOST_AUTO_TEST_CASE_TEMPLATE(MyTest, DecimalIntegralT, EachDecimalWithEachIntegralT) { { typename DecimalIntegralT::item1 r(1234567); // Fails on gcc: no type named ‘item0’ in ‘struct boost::mpl::v_item<long long unsigned int, boost::mpl::v_item<ext::decimal::decimal128, boost::mpl::vector0<mpl_::na>, 0>, 0> typename DecimalIntegralT::item0 d(r); BOOST_CHECK_EQUAL(static_cast<long long>(d), r); } } A complete listing is below. I'm wondering if there is just something simple that needs to be tweaked? The thing that has me really stumped is the type exsits in MSVC, so I'm at a bit of loss of how to proceed debugging.

Boost.Filesystem (?): How to get the platform-specific path separator (not directory separator) ?
by Johannes Stallkamp 14 May '12

14 May '12

Hi all, Boost.Filesystem eases use of path names across platforms w.r.t to the directory separator (slash vs. backslash, as I am only concerned with Linux <-> Windows). Now, I need to handle _lists_ of path names (in an environment variable). Is there a similar transparent way a) to automatically handle or b) access os-specific _path_ separators (colon vs. semicolon) in Boost.Filesystem or Boost in general? In other words, I am looking for the Boost (well, C++) equivalent of Pyhton's os.pathsep, Java's path.separator or PHP's PATH_SEPARATOR. And I am looking for a library function/constant rather than a self-implemented platform-dependent preprocessor directive. The only C++-solution I am currently aware of is "apr_filepath_list_merge"/"apr_filepath_list_split" in Apache Portable Runtime (as mentioned in this answer to my question on stackoverflow: (http://stackoverflow.com/a/10514401/1228449) Is there a similar way in Boost? Kind regards Johannes

Building boost with a locally built g++
by Mark Summerfield 14 May '12

14 May '12

Hi, I have two locally built g++'s and want to build boosts to go with them. Unfortunately I've never used jam and despite reading the docs haven't succeeded. I created a user-config.jam file with the single line: using gcc : 4.7 : /home/mark/opt/gcc47/bin/g++ : <compileflags>-std=c++11 -pedantic <linkflags>-lstdc++ -lpthread -L/home/mark/opt/gcc47/lib -L/home/mark/opt/gcc47/lib64 <address-model>64; but this seems to be ignored. All I want to do is build boost for my local g++ 4.6 in ~/opt/gcc46 and my local g++ 4.7 in ~/opt/gcc47. Can anyone give me or point me to some simple instructions for doing this? I did not find http://www.boost.org/doc/libs/1_49_0/more/getting_started/unix-variants.html at all helpful for my situation. In particular, section 5.2 didn't help and b2 just keeps using the system's /usr/bin/g++. (I want boost primarily for its regex library.) Thanks! PS I'm not a subscriber so would appreciate being cc'd in any reply. -- Mark Summerfield, Qtrac Ltd, www.qtrac.eu C++, Python, Qt, PyQt - training and consultancy "Programming in Go" - ISBN 0321774639 http://www.qtrac.eu/gobook.html

[build] How do I get my trial project to use b2 correctly?
by Daryle Walker 13 May '12

13 May '12

I'm trying out GitHub for the first time. I have a new project thatis supposed to reference my Boost-SVN tree for both the Boostheaders and its build system. I copied the project structure,including Jamfiles, from John Maddock's Multiprecision trial library.I don't think I did it right because calling "b2" doesn't do anything.At first, I got directory errors because it couldn't find my Boost tree.(The "../Trunk" alias doesn't work. Is it because I'm an extradirectory away?) Then I defined "BOOST" in my shell, so "b2" canfind the tree. I just get "1 target found" notices without anythinghappening. I know nothing's being compiled because I called it fortool-sets that aren't C++11-enabled and the build just ends withouterror on my C++11 code. My directories are like: + MyProjects++ boost-trunk++ Trunk (aliased to "boost-trunk")++ Unionize (a Git clone of my project on GitHub) Does anyone want to take a look and see how I have to fix my buildfiles? The project is at "https://github.com/CTMacUser/Unionize". Daryle W.
