Issue Running Regression Tests on msvc-12.0

I have been trying to run a regression test against msvc-12 on Windows 8.1 and I am getting the following errors. In the past, this has run fine.

[parameter] #line markers in literate tests
by Edward Diener 27 Jun '14

27 Jun '14

Is there any logical reason for the #line markers in the source files for the 'literal' tests in Boost parameter ? VC++ will not compile these tests with them and although they appear to me as completely valid C++ I would like to create a pull request to fix the VC++ problem. If there is no reason for the #line markers I can remove them, else I can wrap in "#if !defined(BOOST_MSVC)/#endif" pairs after including boost/config.h.

Boost Build question
by Emil Dotchevski 27 Jun '14

27 Jun '14

Hello, I'm trying to instruct bjam to attempt to output an iphone executable (btw I'm not trying to build Boost itself.) What's the correct way to do this? I apologize if this is explained somewhere, but searching online mostly finds xcode-related information, and the suggestions in the few pages that looked relevant didn't work for me. -- Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode

I just re-assigned these tickets that were incorrectly filed against the regression testing component to the utility library: https://svn.boost.org/trac/boost/ticket/9945 https://svn.boost.org/trac/boost/ticket/9944 https://svn.boost.org/trac/boost/ticket/9925 They are now owned by "no-maintainer".

Boost.Python and __slots__
by Matt Calabrese 26 Jun '14

26 Jun '14

Does something special need to be done to setup __slots__ on a class bound via Boost.Python? I can set __slots__ on the class and verify that it can be accessed from python, however I am still able to set members that aren't in the __slots__ list. -- -Matt Calabrese

How to handle generated html files with modular-boost and GIT?
by Paul A. Bristow 26 Jun '14

26 Jun '14

I've started to proof-read Vladimir Batov's Boost.Convert library and correct a (very few) typos etc. I've had some troublesome experience with building docs with Boost.Math and this is similar (but much smaller). Can experienced GIT users suggest how better to handle the problem of generated files in the /html folder. I've provided below a log of what I've done after a single edit to a Quickbook file. As you will see, there are *new* files (with randomized filenames) html/boost/convert_id274115.html html/boost/convert_id274279.html html/boost/convert_id277698.html html/boost/convert_id277857.html (and also my log file cv_20jun14_1135.log) And all the .html file have been modified. So what do I do? I'd hope just to be able to GIT commit (but there will be added files so "git commit -a") and "git push". (But what about obsolete files like html/boost/convert_id999999.html that should be deleted?) . This seems a muddle, so should we remove the /html folder from GIT using gitignore? However this would mean that users would have to generate the html (and assumes that all the tools like Doxygen and autoIndex are setup right - an unwelcome requirement). And what about .log files - it seems very useful and reasonable to have them live in /doc but be ignored by GIT? Could/Should there be a global entry in top level /modular-boost/.gitignore to exclude all .log files? (I'd also like to put .bat or .sh files to build docs etc here too - there are various options in building and automatically dated log files are nice to have. ) Suggestions on how better to manage this?

ptr_vector requiring non-const iterator for insert
by Florian Burkart 26 Jun '14

26 Jun '14

Hi, I noticed that ptr_vector requires a non-const iterator for insert. This is inherited from ptr_sequence_adapter, which defines iterator insert( iterator position, T* x ); Under C++11, this differs from std::vector, which, since C++11, is happy to take const_iterators. iterator insert( const_iterator pos, const T& value ); I read somewhere that C++11 was attempting to clear up some confusion in the standard between iterator constness and container constness. Just wondering whether this should be adopted (e.g. changed) in ptr containers. Gave me an error when I switched from vector to ptr_vector in a drop-in fashion. Not sure whether that is already planned, but google didn't find anything. Florian

[parameter] 'develop' branch breaks tests with VC++
by Edward Diener 25 Jun '14

25 Jun '14

In testing out potential changes in Boost PP against other Boost libraries, to make sure those changes break no code, I noticed that running tests in the Boost parameter 'develop' branch against VC++ ( msvc-12.0 ) creates a number of compiler errors related to Boost PP.

[git workflow questions for boost]
by Robert Ramey 25 Jun '14

25 Jun '14

I've discovered a couple of changes I want to see incorporated into some boost libraries. In this particular instance the modules are mpl and tools. The "best" way of doing this for me is to: use github to fork the modules in question clone the modules to my local machine make (and test) my changes push them to the the fork enter a pull request. sometime later delete the fork from github This is well described here https://help.github.com/articles/fork-a-repo So far so good. But I have a couple of questions about this. I currently have modular boost installed on my machine. It seems that I want to: delete the module in question. clone to the same spot I just deleted. do everything above. delete the module again. clone from the original? update super project? rerun b2 headers? what? - I'm sort of at a loss here. I'm sort of uncomfortable with deleting the "official" version - but it seems the right think to do. I would appreciate any observations/advice from some more experienced boosters.
