[Geometry] Calculating distances on the earth
by Sean Farrow 19 Mar '12

19 Mar '12

Hi all: I need to calculate distances on the earth. Ideally I'd like to use the haversine formula. There is an example in the docs at: http://www.boost.org/doc/libs/1_49_0/libs/geometry/doc/html/geometry/quicks… under the non-Cartesian heading. Will this do what I need, or do I need the Geographical coordinate system, (if yes where is this available and what features does this supply?) Any help appreciated. Regards Sean.

convert a boost::iostreams::filter_streambuf to a std::wofstream
by Sean Farrow 19 Mar '12

19 Mar '12

Hi: I'm trying to pass a boost::iostreams::filtering_streambuf to a boost::archive constructor. I'm using visual studio 2010, and am getting c2664 telling me that this conversion carn't be performed. Is there anyway I can convert a boost::iostreams::filtering_streambuf. Any help appreciated. Cheers Sean.

Hello, I just subscribed to this mailing list. I have a question that I originally sent to David Abrahams, and I'm hoping someone can help. Dear Sir or Madam, I am currently using boost in a simulator and have a few questions regarding the special functions that are (are not) available. 1. Do your special functions accept complex numbers as input and provide complex output? I am specifically interested in the Bessel functions. In most applications the argument is restricted to be positive and the index to be real. However, Bessel functions are defined for complex index and argument, the former arises in acoustic and optical wave guide problems.If the answer to 1 is no I’d suggest these capabilities as a future nice to have. 2. Does Boost plan to have hypergeometric functions in the future? They are currently listed as unsupported TR1 functions. I have not been able to find them in TR1 either but I’m not done looking. Thanks in advance for your help. David

It was the question of binary files. Thank You for Your help.

It sounds like you're opening the files in text mode. This causes Windows to insert a carriage return (0x0D) before each line feed (0x0A), but has no effect on Linux or other Unix-like operating systems. Here is the actual code I use to open a gz or bz2 file for writing in one of my projects, which produced valid gz files with boost 1.48 (untested with 1.49) and Visual Studio 2010, both in i386 and AMD64 modes. Ignore the references to tbb::scalable_allocator. In particular, note the last line where I specify the file_sink should be binary: boost::iostreams::filtering_stream <boost::iostreams::output, char, std::char_traits <char>, tbb::scalable_allocator <char>> output_file; if (boost::iends_with (file_name, ".gz")) output_file.push (boost::iostreams::basic_gzip_compressor <tbb::scalable_allocator <char>> (boost::iostreams::zlib::best_compression)); else if (boost::iends_with (file_name, ".bz2")) output_file.push (boost::iostreams::basic_bzip2_compressor <tbb::scalable_allocator <char>> ()); output_file.push (boost::iostreams::file_sink (file_name.c_str(), std::ios::out | std::ios::binary));

boost.zlib on Windows
by László Marák 19 Mar '12

19 Mar '12

Dear Boost Users, I would like to ask You what is the status of Boost.zlib on Windows. I have a program that uses Boost.iostreams to create a gzip file. It compiles both on Windows and Linux and on Linux it creates a functional gz file. On Windows it creates a gz file but when I try to decompress the file it gives me "data error". When I look at Boost's regression tests both gzip and zlib is missing on Windows. Has anybody successfully run Boost.zlib on Windows recently? Is there some flush method that should be called, but on Linux it does not show any symptoms? Thank You in advance, UJ

how to contribute documentation for boost.enum in the boost vault
by Carsten Greiner 17 Mar '12

17 Mar '12

Hello, in the boost vault exists the boost_enum library. (file name enum_rev4.6.zip). and I have four questions: - provided I create documentation for it, could someone assist me in adding it to the package? - which mailing list is appropriate for reviewing feedback of the created documentation (maybe that Q applies to all of my points) - what format should I use when creating the documentation - and last but not least: adding it to the official release would be initiated then via the development list, right? cheers, Carsten.

boost error
by Pervez, Salman 16 Mar '12

16 Mar '12

Hi everyone, I am trying to do a source build for qpid 0.14. I am running into a boost dependency error which I am unable to solve. Here is the error... /usr/bin/ld: cannot find -lboost_program_options collect2: ld returned 1 exit status make[2]: *** [libqpidcommon.la] Error 1 I also built boost from source so its no surprise that it cannot find the required file in /usr/bin/ld. Perhaps there is a way to tell it where to find boost? I passed the location of my boost build to the configure script through a CPPFLAG which helps it find the hpp files but perhaps not this one. I realize the error output is limited but I also didn't want to mess everything up with meaningless output. If you require more info I'll be happy to post the rest of the output along with the error message. I'll appreciate any input on this. Thanks!
