[website] Redirection to latest documentation
by Laurent Dupuy 23 Oct '13

23 Oct '13

Hello all, Would it be possible for the webmaster(s) to add a redirection (a symbolic link or whatever) to the latest documentation? Until recently, the URL http://www.boost.org/doc/libs/ did the job, but it does not anymore. Thanks! -- Laurent Dupuy.

Boost.Build commit heads up
by Beman Dawes 23 Oct '13

23 Oct '13

Here is the commit message for revision 86392: Add Boost.Build support for the Git modular layout, using links to to new header locations, thus preventing breakage to vast amounts of user code and build setups. Being added to SVN so that changes will automatically propagate to Git and modular Boost. Thanks to Steven Watanabe, Jürgen Hunold, Vladimir Prus, and Bjørn Roald for developing this patch. Steven in particular conceived the approach and did the initial implementation, which was further refined by the other contributors. In theory this commit won't break any existing boost builds. To verify that, on Win 7 and Ubunto I've done a fresh SVN checkout of trunk and verified bootstrap.bat, bootstrap.sh, and a b2 build work both before and after the patch is applied. On Windows, I verified that after the patch is applied a b2 build using an unpatched prior compilation of b2 still works. These tests increase confidence that committing the patch to trunk now isn't likely to cause breakage, but please post to this list right away if you spot any build breakage or other odd behavior. The files modified are listed below.

Re: [boost] [git help] Documenting common modular boost workflows
by Daryle Walker 23 Oct '13

23 Oct '13

Since a project that’s made of a bunch of sub-repositories that’s later merged is (AFAIK) unusual, I don’t think the writer of gitflow had it in mind. I’m guessing that each sub-repository independently uses gitflow. When it’s shipping time, the release-merge script grabs from the “master” branch of each sub-repository. Of course, this doesn’t cover multiple libraries that have to work together or what happens when fixing is necessary (probably due to cross-library problems). And do the test runners work off “develop,” “master,” “release,” or does it shift depending where we are in the release cycle?

When Boost release 1.64.0 is started, who is going to create the gitflow release branch, and from what? _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost

Reading & Parsing an .ini input file using BOOST... ..!!
by Rahul Mathur 22 Oct '13

22 Oct '13

All, Need small help. I have an "input.ini" input file which contains sample values like – --- App=| 5000 | 5001 | 0 | | | | 1BYTE | --- Starting with word (viz. App), followed by equal sign, than data within pipes (|) and blank space between two pipes ( | | ). Anything only between two pipes is to be read. I am looking to parse this input file. After parsing, assign each data to struct member type and than send this complete struct as socket. I am looking to use Boost property tree (or the needed one) and finally the ASIO to send the complete filled struct as stream. I tried below code to read complete data and it worked but - --- #include <iostream> #include <boost/property_tree/ptree.hpp> #include <boost/property_tree/ini_parser.hpp> #include <boost/filesystem/fstream.hpp> int main() { boost::property_tree::ptree pt; boost::property_tree::ini_parser::read_ini("input.ini", pt); std::cout << pt.get<std::string>("App") << std::endl; } --- But, how to read between pipes? Any clue?

(my last email is still in moderaition because of the zip with the log) On Tue, Oct 22, 2013 at 11:40 PM, Klaim - Joël Lamotte <mjklaim(a)gmail.com>wrote: > The boost build on my Win764bit finished for me for both VS2012 and > VS2013, apparently no error in the log I'm attaching to this mail with the > build script (which uses b2). > I'll try now to compile my main project. > I forgot to say that the revision I built was trunk r86395. So building boost with b2 now don't spawn errors, but compiling my project I still hit this bug: https://svn.boost.org/trac/boost/ticket/9266 see comments for details. (By the way, does the test suite is able to catch such compiler crashes?) To continue compiling my project, see other errors, I modified synchronized_value to activate only the code that do use variadic templates, which is a workaround I suggested in the bug report. I'm waiting for the rest of the project build right now.

[1.55] VS2013 massively failing
by Joaquin M Lopez Munoz 22 Oct '13

22 Oct '13

I understand this is being taken care of, but... VS2013 is failing to pass most libs in the release branch. For the one I care about most the problem is: D:\teeks99-10\boost\boost/mpl/aux_/preprocessed/plain/arg.hpp(45) : error C2039: 'assert_not_arg' : is not a member of 'boost::mpl' which seems to be fixed in trunk. Thank you, Joaquín M López Muñoz Telefónica Digital

Request permission to apply patch to trunk.
by Beman Dawes 22 Oct '13

22 Oct '13

I'd like to apply the attached patch to trunk. It is not supposed to break anything on an svn checkout, but we held off applying it until 1.55 beta shipped because of concern it would be disruptive if it somehow messed up the build system right in the middle of getting the beta out. Thanks to Bjørn Roald for developing the patch. Without this patch, the only way to test modular-boost headers mechanism is to manually apply the patch yourself, and that pretty much limits testing. OK to apply? --Beman

[modernization][skelly] Surprising changes
by Agustín K-ballo Bergé 22 Oct '13

22 Oct '13

I was going through recent Boost.Spirit changes and I was surprised to see this code: #if (defined(BOOST_MSVC) && (BOOST_MSVC < 1310)) \ || (defined(__BORLANDC__) && (__BORLANDC__ <= 0x570)) \ || (defined(__GNUC__) && (__GNUC__ < 3)) \ || (defined(__GNUC__) && (__GNUC__ == 3) && (__GNUC_MINOR__ < 1)) # error "Compiler not supported. See note in <boost/spirit/core/config.hpp>" #else // Pass... Compiler supported. #endif modified into this code: #if (defined(__BORLANDC__) && (__BORLANDC__ <= 0x570)) # error "Compiler not supported. See note in <boost/spirit/core/config.hpp>" #else // Pass... Compiler supported. #endif The whole point of the check is to detect unsupported compilers. It seems the modernization changes do not take into account the context in which they are done. To Stephen Kelly: I would like to suggest going over your modernization commits looking for unwanted changes like this one, and reverting them. I have already revisited your modifications to Boost.Spirit and found all changes but the one I mentioned to be valid ones (thank you for those!).

[multiprecision] New binary floating point type
by John Maddock 21 Oct '13

21 Oct '13

Folks, One of the main feature requests during the multiprecision lib review was for a binary floating point type. There is now such a type in the sandbox under the "multiprecision.cpp_bin_float" directory - you will also need latest SVN Trunk to try this out. This new type is correctly rounded to nearest for all arithmetic operations plus binary-decimal conversions and sqrt. Minimal docs so far here: https://svn.boost.org/svn/boost/sandbox/multiprecision.cpp_bin_float/libs/m… I'd welcome comments, and if folks would like to try and break it, that would be cool too ;-) Regards, John.
