serialization code compilation problem - shared_ptr_helper.cpp in Boost 1.59
by Robert Fairlie 06 Oct '15

06 Oct '15

I tried building the serialization library only using the standard b2 approach and looking at the output. It looks like shared_ptr_helper.cpp isn’t included in the build (at least for serialization). So I just left it out of my own build and my code compiled and linked OK, and my serialization seems to be working. Does this approach sound safe or am I overlooking something?

serialization code compilation problem - shared_ptr_helper.cpp in Boost 1.59
by Robert Fairlie 06 Oct '15

06 Oct '15

Hi, I’m building the Boost serialization library in Visual Studio 2015 (for x86 and ARM) by copying the 40 or so files in libs\serialization\src and compiling them in my Visual Studio project. (I’m doing it this way because Visual Studio won’t seem to let me build everything with b2 in the ARM case). The last build of the 40 files I did used Boost 1.55 and that worked fine, but now with Boost 1.59, all files compile except shared_ptr_helper.cpp. I notice that shared_ptr_helper.cpp refers to a class called shared_ptr_helper_base, but I’ve done a full *.* search and it doesn’t seem to be declared anywhere. Also, I notice that usage of macros such as BOOST_ARCHIVE_DECL has been updated in other files, but not in shared_ptr_helper. Any advice on this would be much appreciated. Robert Fairlie

[geometry] is there an rtree version that works with boost.1.49 and MSVC2010?
by Jeff Flinn 06 Oct '15

I pulled the version down from the old svn sandbox, but msvc2010 doesn't support the variadic template args in indexable.hpp. Any help appreciated. Thanks, Jeff

Container features in regards to IPC
by David Schneider 05 Oct '15

05 Oct '15

Hello, I was wondering if I could suggest adding the ability to have separate allocators inside containers so that the structure (such as map) can be in a different shared memory region, or whatever, than the data. It would have variety of useful cases such as offline storage swapping out, inter-process communications, etc. This can be realized by a bit of a hack with a bunch of boiler-plate code, but I think that this could be a very useful extension over what is available in the standard library.

how to get auto_link to use shared libraries

I am trying to use Boost 1.59.0 with Visual Studio 2015 I believe I have built correctly the shared libraries as I have the following files in stage/lib 10/03/2015 04:48 PM 968,192 boost_regex-vc140-mt-1_59.dll 10/03/2015 04:48 PM 1,100,728 boost_regex-vc140-mt-1_59.lib 10/03/2015 03:59 PM 2,561,024 boost_regex-vc140-mt-gd-1_59.dll 10/03/2015 03:59 PM 1,103,914 boost_regex-vc140-mt-gd-1_59.lib I am trying to build the credit_card_example from http://www.boost.org/doc/libs/1_59_0/libs/regex/example/snippets/credit_car… I do have several static libraries in my stage/lib.

range: partition a transformed range adaptor
by Auer, Jens 02 Oct '15

02 Oct '15

Hi, So today I wanted to partition a transformed range. I came up with something like std::vector<int> v; auto t2 = r | transformed( [](int) {return 0;} ); auto p2 = boost::range::partition(t2, [](int) {return true;} ); , but that didn't work. On Stackoverflow, it was explained that this doesn't work because partition needs to modify the range, and a transformed range is not modifiable. So far so good, I can follow this and see why and modify the program to use transform on the vector directly. What bothers me is that I was not able to figure that out from the documentation, and that the error message was not very intuitive to say the least. According to the documentation, the requirements on the range for partition are that it has to be a model of ForwardRange, which means that the iterators have to be forward traversable iterators. I think the important fact, namely that it has to be writeable iterator, is missing from the documentation completely. As far as I can see, readable/writable categories are not used in the range documentation at all. Best wishes, Jens -- Dr. Jens Auer | CGI | Software Engineer CGI Deutschland Ltd. & Co.

parallelised ODE solvers
by Vihan Pandey 01 Oct '15

01 Oct '15

Dear all, I am trying to integrate a simple 2 variable ODE system. I wanted to know which of the solvers listed here : http://www.boost.org/doc/libs/1_56_0/libs/numeric/odeint/doc/html/boost_num… are parallelised for multicore CPU’s and GPU’s? Perhaps using Thrust for the Nvidia/CUDA GPU end of things? I am principally interested if someone has managed to make/port a library for parallelised RK45 methods. Please note in later work I plan on having more ODE's - probably systems of 12-15 parameters though they will be all be first order equations. Thanks and Cheers! - vihan -- Listening to Ozzy again!

Hi!I'm a C++ beginner and any help would be very much appreciated.I would like to convert this "std::sort" into "boost::sort::spreadsort::integer_sort".I know that I have to write "#include <boost/sort/spreadsort/integer_sort.hpp>" inmy header instead of "#include <algorithm>" but after that, this is too difficult...Thanks!-------------------------------------------------------------------#include <iostream>#include <algorithm>using namespace std;int main() { int nb1[4] = {15, 5, 0, 20}; int nb2[4] = {99,102, 8, 2}; int indices[4]; for (short i=0; i<4; i++) indices[i]=i; sort(begin(indices), end(indices), [&](int i1, int i2) { return nb1[i1] < nb1[i2]; } ); for (short i=0; i<4; i++) cout << nb1[indices[i]] << ' '; cout <<endl; // 0 5 15 20 for (short i=0; i<4; i++) cout << nb2[indices[i]] << ' '; cout <<endl; // 8 102 99 2 return 0;}---------------------------------------------------------------------

program_option parsing error
by Marek Skalický 30 Sep '15

30 Sep '15

Hello everyone, I have a question about program_option library. If I have argv=["binaryname", "--port", "5"] and port have set default_value=6 and implicit_value=7 what should be the value of port after parsing argv? I am asking because this test https://github.com/mongodb/mongo/blob/0481c958daeb2969800511e7475dc66986fa9… is failing with boost 1.59 (with boost 1.58 it is passing). Does someone please know what changed in this new version? Thank you, Marek
