Functors and Boost::MPL
by Dan 14 Jul '04

14 Jul '04

It occurs to me that it should be possible to manage an mpl::vector of types which are actually functors. One could add functors to this list with compile time complexity and likewise call all the functors in the list with compile time complexity. Requiring none of the function pointers, class templates, or virtual functions typically used for this purpose. I think it should be easy to create the vector, but how does one construct an object of each type and call operator() on it? -Dan "The only impossible task is the task you never start"

[assign] not in status/Jamfile

Shouldn't be there an entry for this lib in status/Jamfile? The code is checked in since 2 weeks ago. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

Re:[boost] Re: serialization:question regarding test
by Robert Ramey 14 Jul '04

I don't see that this should be a problem. Just follow the instructions in the release notes: a) Download spirit 1.61 from SourceForge.net to a local directory. On my machine its c:/spirit161 b) Define (export) environmental variable SPIRIT_ROOT=c:/spirit161. The build/test jamfile set up is sensitive to the SPIRIT_ROOT variable and will put it in the include path for those systems that are known to require it. Right not that is msvc 6.0 and all tested borland compilers. Other compilers just work with the latest version of spirit from the CVS Tree. This works on my system without any other special adjustments other than the above. So I'm asking that the testers set up their environment as above before running the tests. I don't think that's an unreasonable request. In fact, I believe this should be seen as a vindication and demonstration of the power and flexibility of the bjam/jamfile system rather than an extra burden.

serialization:question regarding test
by Robert Ramey 14 Jul '04

14 Jul '04

It seems I've succeeded in getting my serialization project checked in. (I've held back the Jamfile in the test directory pending a tiny tweak) And I have a couple of questions regarding testing. a) in order for libraries to be built for Borland and VC 6.0 which don't support Spirit 1.8 but do support spirit 1.6, the Jamfile checks for the environmental variable SPIRIT_ROOT and if found presumes it contains the root of the directory where Spirit 1.6 is located. This has worked well in my local environment. An environment which tests this library for these compilers will also need to have Spirit 1.6 installed and have the SPIRIT_ROOT variable set accordingly. I don't know who I should inform about this. b) its unclear to me how to exclude certain platforms. I've been unable go get non-intrusive serialization with Commeau - much to my disappointement. This is pretty much a show-stopper for this compiler. (Other than this it seems to compile cleanly - though perhaps a tad picky with warnings). So I would like to know how to exclude Comeau from the tests. c) As currently loaded, the test programs create temporary files in the systems temporary directory. And leaves them there - I occasionally delete them in masse. It only just dawned on me that this would be very inconvenient for the test setup so I'm going to tweak the tests to remove their trash at the end. So in some case some trash may be left over but shouldn't accumulate at a large rate as before. I hope this is acceptable. Robert Ramey

Another spirit compile problem using HP aC++
by DY, JERRY U (SBCSI) 14 Jul '04

14 Jul '04

Here's another problem while compiling with aC++. This has been reported to the HP aC++ team, but in the meantime, I'm posting this fix to the list for review and for future users of Spirit for aC++. BTW, I'm a little afraid to commit changes to the repository, so quick question: If I end up committing changes that need to be backed out, can I delete that version that I committed easily? Thanks! boost/spirit/core/primitives/impl/match.ipp:101 ===old=== inline void match<nil_t>::swap(match& other) { std::swap(len, other.len); } ===new=== inline void match<nil_t>::swap(match<nil_t>& other) { std::swap(len, other.len); } -Jerry

uBLAS developers meeting ?
by Toon Knapen 14 Jul '04

14 Jul '04

I was discussing with Michael Stevens about organising a uBLAS developers meeting. And thus we decided to ask the community if 1) there would be any interest, 2) which topics people would like to discuss 3) what format would best fit, 4) and finally where and when. As for the topics (item 2), I think following list are certainly candidates: Evaluation of the design of uBLAS and discussion of future design Evaluation of the efficieny of uBLAS Syntax and ET engine Evaluation of the documentation and how to go from there. Restating the main goals of uBLAS Organisation of ublas project. overview of applications using uBLAS. As for the format I think most important are having intense discussions on the topics above. Presentations (by volunteers) could serve to initiate the dicussion on specific topics. Where and when to organise it probably depends on the interest from the developers. It seems like many active ublas-dev members are at most a few 100km from Cologne (Germany) so getting this group together could be easy in a small timeframe. But it is probably easier to discuss the 'where and when' once we have more information about 'who' would like to attend. toon
