Bost.thread: how to force Pthreads-w32 usage with MingW (x-compile)?
by Joost Kraaijeveld 26 Aug '10

26 Aug '10

Hi, I have x-compiled Boost using Pthreads-w32, using threading=multi,single threadapi=pthread. But when I x-compile my application Boost uses the win32 headers. I have looked at the thread sources but I cannot find out if it just should work or that I should use some macros. Can anyone help me with this? TIA -- Groeten, Joost Kraaijeveld Askesis B.V.

[MultiArray, Thread] Setting the _ITERATOR_DEBUG_LEVEL
by lfrfly＠icqmail.com 24 Aug '10

24 Aug '10

It's probably well-known by now that multi_array has a problem with Visual Studio 2010: due to the way it identifies its iterators, you get errors unless you set the _ITERATOR_DEBUG_LEVEL preprocessor symbol to 0. First of all, when can we expect a fix for this (or is there one already)? Secondly, even if I manually set the _ITERATOR_DEBUG_LEVEL to 0 in Debug configuration (that's the default in Release), I am unable to build because when I try to link in the Boost Thread library, I get 2>libboost_thread-vc100-mt-gd-1_43.lib(thread.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '2' doesn't match value '0' in test.obj This indicates that I need to build Boost Thread with that variable set to 0 as well, even in the debug mode; or else I need to somehow get the Release version of the library linked in instead. I'm not sure how to do either one of these options. Can anyone help me configure bjam to override the variable, or else override which lib is linked?

[boost-users][asio] Interaction problem with signals2?
by Germán Diago 24 Aug '10

24 Aug '10

Hello. I'm trying to call a signal after an async_read from inside a function called by boost::asio::io_service. The run function runs in a thread, and the observers are connected in a different thread. This is causing errors. It's my program or it's not possible to invoke a handler that is running in another thread from io_service::run? Thanks in advance.

using Regex and other Boost libraries that require a build
by Bhushan Inamdar 24 Aug '10

24 Aug '10

Hi all, I am relatively new to Boost but was wanting to install and do development on it for long now. Finally, I can now spare some time for that. I am using Visual Studio 2008 professional edition as a development IDE. I have installed Visual Assist X to assist me with the intellisense as well. I am having Windows 7 ultimate installed on my machine and I am trying to install latest i.e. BOOST 1.44.0 version. So far I have had partial success. I am able to build and compile the sample program on Boost site that needs only headers. But I am facing problems while building programs that reference other libraries. So here is what I did: - Tried unsuccessfully to install it using BoostPro; installation broke quite a few times. - So I gave up and downloaded the Boost compressed version and extracted it successfully in C: drive - The current location is C:\Program Files\Boost\Boost_1_44_0\....and the respective dir structure thereafter. - Then I downloaded the bjam utility and extracted it and then copied it to the Boost root dir - Following this, I double clicked bjam.exe and it ran the build. However, a lot of projects were skipped and virtually nothing was build. - Then I realized that it was Windows 7 we were dealing with and then immediately ran Bjam.exe as an administrator. - This time, it took a lot longer and I was seeing the compilation in progress and I think that it was satisfactory. - Then comes the part of linking the libraries through VC++ compiler to the code. - I then navigated to Tools->Options->Projects and Solutions->VC++Directories and selected Win32 on first combo on top left - There I selected Includes in the other combo on top right and added the C:\Program Files\Boost\Boost_1_44_0\Boost to the list - Then on the same page I changed the top right combo to Libraries and added C:\Program Files\Boost\Boost_1_44_0\libs to the list - Considering that I should not miss out on any other libraries, I added C:\Program Files\Boost\Boost_1_44_0\bin.V2 to the list as well; this directory was constructed as a result of build by Bjam.exe - Following that, I quickly followed the 2 tutorials on Boost site 1 for simple iostream (which worked after some adjustments) and the other for regex (which did not work). - Considering I might still have missed something, I went on to add the path C:\Program Files\Boost\Boost_1_44_0 to System variables and made changes to VC IDE accordingly. - Also, to mention, I did not find any simple way to build the libraries that need a separate build and neither did I found any simple tutorial on Boost site...where they have put the regex sample that extracts matched text from a paragraph So my questions: - I want to know if I have missed anything to build any of Boost libraries or link to VC IDE or else? - Is there a better way to make sure if all the variants of all the libraries are build and linked with VC? - Is there a way to do this with CMake? - I read that, some libraries have some dependencies like libz...etc. where can I get the list for all Boost libraries? - Although this Question is not related to Boost, on a lighter note, I would just want ask this. Please ignore this if it does not hold ground. I have installed Boost after I installed Visual Assist for Visual Studio. Hence, whereever I use Boost members and classes, it keeps on saying that refactoring data is not available. Hence, I presume that, if I uninstall and reinstall Visual Assist, it should help? Or in other words, is there a better way to refactor boost library code so that intellisense can pick that? I will continue searching for this and hope that there is an option in Visual Assist itself. Nonetheless, it is not as important as Boost build related questions. Hope to hear from you soon... Thanks and Regards, Bhushan.

preprocessing error
by Arnaud GELAS 24 Aug '10

Hi all, When compiling some code using boost, I get the following error: /usr/include/boost/type_traits/type_with_alignment.hpp:142: error: Not a valid preprocessing token ")BOOST_PP_LIST_FOLD_LEFT_CHECK_BOOST_PP_IIF" For more details, I posted the log here: http://gofigure2.sourceforge.net/temp/boost-error.txt Any idea what I could do wrong? My machine is a Fedora 13 (64 bits), the installed version of boost is 1.41.0, and I used gcc 4.4.4... Thanks in advance, Arnaud

Boost.Format
by John Dlugosz 24 Aug '10

24 Aug '10

I'm using Boost.Format as a simple way to create strings to pass to exception constructors and primitive logging output during debugging (Windows' OutputDebugString). I see that the format object can be inserted into a stream, easily. But, with arguments, it's awkward to convert it to a string -- you need extra parens around the whole thing. Is there some good reason why there is no implicit conversion to string? E.g. string message= boost.format("blah") % argument % errorcode; OutputDebugStringA (message.c_str()); throw std::runtime_error (message); Or, is there some simple way that I'm missing?

building all libs
by Kraus Philipp 24 Aug '10

Hi, I use boost with thread, iostreams and random. I compiled bjam first and uses them to compile all, but I must call every lib manual with ./bjam variant=release toolset=darwin threading=multi variant=release libs/iostreams/build How can I build the full boost with all libs in one run? Thanks Phil
