Re: [Boost-users] cross-compilation x86_64-w64-ming32: undefined reference to `InterlockedIncrement'
by Frédéric Bron 23 Sep '13

23 Sep '13

So I eventually managed to fix the issue with interlocked.hpp and mingw-w64: both i686 and x86_64 now work. Attached is a patch against 1.54.0. Is it possible to include this in 1.55.0? Regards, Frédéric

Multiple instance of options
by Ulf Samuelsson 22 Sep '13

22 Sep '13

Need to parse an "ini" file which configures one or more sensors. The sensors can be of the same type and are identified by "name", "type" and an "id" Some configuration items are for all sensors Other configuration tiems are only for some sensors. [sensor] SensorName="Outdoor Temp" SensorType=1 # Temp Sensor SensorID=1000 SerialNumber="12344" Active=1 Device="/dev/ttyUSB01" [sensor] SensorName="Indoor Temp" SensorType=1 # Temp Sensor SensorID=1001 SerialNumber="12345" Active=1 Device="/dev/USB02" [sensor] SensorName="Light" SensorType=2 # Light Sensor SensorID=1002 SerialNumber="12349" Active=1 Device="/dev/ttyUSB02" MaxLumen="500" Is having multiple identical section names possible with boost program options? It is of course possible to do [sensor_1] ... [sensor_2] ... [sensor_3] ... but that is not so nice looking, and you get a hard limit on the number of sensors you can attach. Ideas?

Question about boost.build and automatic selection of toolsets
by Mauricio Carneiro 22 Sep '13

22 Sep '13

I am using boost-build in my project (very happy with the outcome) but I would like to have the toolset selected automatically based on the operating system. Currently I am running successfully from the command line by manually setting the toolset when I am running it from macos and linux accordingly, but I feel like the Jamroot file should be able to figure that out for me. Any ideas? I made a more descriptive post on stack overflow, to share the knowledge once we figure this one out. http://stackoverflow.com/questions/18939911/choosing-compiler-options-based… Thank you, Mauricio Carneiro, Ph.D. http://www.broadinstitute.org/~carneiro/

units
by Robert Ramey 22 Sep '13

22 Sep '13

I have a program in which there is the notion of consumption rate such as m^3/sec, gallons/hour, etc. I have consumption_rate unit defined in terms of si units. I read in a quanity in gallons/hour and so far so good. If I display the quantity it is displayed as m^3/sec. This displays the "compound units" as expected - very cool. All this is OK as far as it goes. When I try to display the quantity as gallons/hour again I have a whole host of problems. The attached test fill illustrates the issues. The only way I've been able to do is is by making a complete end run around the units system itself - sort of self defeating. I would appreciate insight anyone might be able to offer into this issue.

Boost::Bind Problem
by vishal rawate 21 Sep '13

21 Sep '13

Hello, I am trying to use Boost::Bind to bind my function but I am getting an error as Bind cannot diffrentiate between the constructors even though they have diffrent function signatures. TestBind(boost::bind((&Test::process), &t1, _1)); I would highly appreciate any help. Thanks //Boost Includes #include <boost/function.hpp> #include <boost/bind.hpp> #include <boost/enable_shared_from_this.hpp> namespace test{ struct A{ public: int one; int two; }; struct B{ public: short three; short four; }; typedef boost::shared_ptr<A> t_boostInt; typedef boost::shared_ptr<B> t_boostShort; class TestBind{ public: typedef boost::function< int (t_boostInt)> t_ProcessFunctionInt; public: ///< call back process function for short typedef boost::function< short (t_boostShort)> t_ProcessFunctionShort; public: TestBind( t_ProcessFunctionInt func){} TestBind(t_ProcessFunctionShort func){} }; class Test { public: Test(){} ~Test(); public: int process(t_boostInt msg) { return 1;} }; int main(int argc, char * argv[]) { try { Test t1; TestBind(boost::bind((&Test::process), &t1, _1)); } catch (std::exception & exception) { std::cout << exception.what() << std::endl; } return 0; } }

Newbie boost::spirit rule semantic action question
by LeMay.Steve 21 Sep '13

21 Sep '13

Brand-newbie boost::spirit::qi question. MSVS2012, boost 1.54 I have a response from a serial device that provides with 0 or more "profiles" in a given character format. I want to capture the number of profile responses in the list (semantic action) as well as have the value into the final result (std::vector<std::string>). How do I properly express this? Given the input.... (in this case, there are zero profiles returned) *ARSS:0<CR><LF>OK<CR><LF> Expect a vector of strings containing "*ARSS" "0" "OK" This sub-rule fails to return... (Not failing to parse) boost::spirit::qi::rule<Iter, std::vector<std::string>(), boost::spirit::qi::locals<int, std::string>> service_search_list; service_search_list %= // %= operator is necessary for attribute propagation when using symantic attributes (anything in [ ]) string ("*ARSS") >> colon >> // Initial response +digit [qi::_a = qi::_1] >> crlf >> // Number of discovered devices - save in local qi::_a qi::omit [ok [qi::_b = qi::_1]] >> // Match but don't emit the "OK" here - save it for the end qi::repeat (qi::_a) // Repeat for each discovered device [ crlf >> ( qi::hold [profile1] | qi::hold [profile2] ... ) ] >> qi::attr(qi::_b); // Emit the "OK" here at the end of the list Using qi::int_[qi::_a = qi::_1] provides and empty string "" in the result and not "0". If I omit the numeric input from the result... qi::omit [qi::int_[qi::_a = qi::_1]] the parse will succeed but number of items in the response list is lost in the final result (omitted as requested). Any suggestion is appreciated, I'm stumped.

Re: [Boost-users] Boost::Bind Problem

Try use TestBind f(boost::bind(boost::type<TestBind::t_ProcessFunctionInt>(), (&Test::process), &t1, _1)); for ambiguity. Either ...boost::bind<TestBind::t_ProcessFunctionInt>..., but less portable.

[units] Convert from Degree Minutes to Degrees
by Ryan 20 Sep '13

20 Sep '13

Angles have their own system that define both radians and degrees. I would like to create the necessary type for minutes (this is 1/60 of a degree). My first thought was to create a scale unit with degrees as the base type. I couldn't determine how to enter the scale of 1/60. The other option is to define a new base unit. I would think using the degrees base unit would be a good reference, but it uses an "INTERNAL ONLY" macro call "BOOST_UNITS_DEFINE_BASE_UNIT_WITH_CONVERSIONS". What should I use to create a unit type that will convert from degree minutes to just degrees? Ryan
