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

[Signals][Patch] test/ordering_test.cpp
by Juergen Hunold 14 Jul '04

14 Jul '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi ! the test in ordering_test.cpp does not use the BOOST_SIGNALS_NAMESPACE #define and therefore breaks if BOOST_SIGNALS_NAMESPACE is #defined to something else (for Qt-compatibilty, for example).

typeof
by Arkadiy Vertleyb 14 Jul '04

14 Jul '04

Hi everybody, Please find at http://groups.yahoo.com/group/boost/files/typeof.zip (and in the Spirit repository, TYPEOF_DEV branch) a new version of my typeof emulation library. This version has the documentation, as well as support for the following has been added: - arrays; - function pointers; - pointers to member functions; - pointers to data members. Any comments are welcome. I would also again greatly appreciate if anybody could try to compile the test with any compiler except VC7.1 (which I have), GCC and Metrowerks (which have native typeof support), or any compiler that does not support partial template specialization (which would not compile this anyway). Best regards, Arkadiy

compiling spirit parser using aC++
by DY, JERRY U (SBCSI) 14 Jul '04

14 Jul '04

I'm trying to get spirit parser to compile in aC++, but aC++ errors on the following line. The problem apparently is that aC++ is not recognizing extract_int_ as a type, so a preceding typename keyword is required for it to compile. Hoping to get instruction on how to change this so that it won't break other compilers? Thanks! boost/spirit/core/primitives/impl/numerics.ipp:305 return extract_int_<(MaxDigits >= 0)>::template apply<Radix, MinDigits, MaxDigits, Accumulate>:: f(scan, n, count); fixed for aC++ is as follows, but may break other compilers??: return typename extract_int_<(MaxDigits >= 0)>::template apply<Radix, MinDigits, MaxDigits, Accumulate>:: f(scan, n, count); -Jerry

Math functions for statistics - a draft TR2 proposal.
by Paul A Bristow 13 Jul '04

13 Jul '04

As promised recently, I am presenting a draft of proposals for math functions which are needed for even most elementary statistics. I have been encouraged to submit this to both the C and C++ Standard Library groups at the same time. (They seem to speaking more than in the past). These are additions to the list drawn up by Walter Brown accepted into TR-1. The style and format follows his closely even though there were some opposition to them from the C++ community. However I think we have to accept that C and C++ compatibility are valued more than C++ 'ideality', and not try to re-open this area of dissent. The draft has been uploaded to the files area in a new folder Math Functions as "More Mathematical Functions.pdf" 220 kb. I'd be grateful if some CVS whizz would copy it to the sandbox as I know that many are unable to access the fiels section. It would be useful to have comments on 1 Typographical mistakes. 2 Mathematical mistakes (prepared by someone with seriously rusty math!). 3 The choice of functions espcially if there are any your feel strongly are missing, or are not needed (say why). 4 The choice of names. Clarity is preferred to curtness. 5 The choice of names for derivatives like the inverse and complement. I have added suffixes _inc and _c (or _com?). ( for C there will be suffixes f and l for the float and long double versions). Thanks. Paul PS I am on holiday for two weeks and will not respond to your observations until July.
