Yeah we've been looking at POCO since it was mentioned here, and it really does look very good compared to ACE. I think if you wanted more of a framework, you might go with ACE.

using lu_substitute
by arun.s 23 Jul '06

23 Jul '06

Hello, Iam trying to use lu_factorize and lu_solve for solving a linear system Ax= B where matrix A has entries of type double and vector B entries of type point ( a simple class wrapping double [3] ) but I get compiler errors in in_place_solve ( all of the overrides have this problem) BOOST_UBLAS_CHECK (e1 () (n, n) != value_type (0), singular ()); apparently this expects that "double" and "point" are comparable using != operator. The problems disappear if I change the line to BOOST_UBLAS_CHECK (e1 () (n, n) != E1::value_type (0), singular ()); but I leave it for the experts to give me the correct solution. PS : I tried to switch to MTL after this, but it too, had the same problem. Thanks, Arun

Naming integer, real and either template types
by Paul A Bristow 23 Jul '06

23 Jul '06

I am writing template math functions. Some can take integral types (only) Some can take real (both built-in floating-point - float, double.. AND User Defined real types) And some can take either integral OR real. Real : Floating-point types Integer : Integral types Arithmetic : Either Integral OR Floating-point types Arithmetic is a bit long - other ideas? So to write a function something like template <class RealType> RealType students_t(ArithmeticType degrees_of_freedom, RealType t) { ... } Using just T is not an option because there are three (at least) possibles. What names should I use for the types? RealType, real_type, RealT, or RT, or ??? IntType, int_type, IntT, IT, or ??? ArithmeticType, arithmetic_type, ArithType, arith_type, AT ??? Suggestions for names please. Rationales? Prior art? Precedents? Standards?

[integer] endian-0.6 posted w/ names changed
by Beman Dawes 22 Jul '06

22 Jul '06

endian-0.6.zip has been posted in the integer directory of the file vault at http://boost-consulting.com/vault/ The only important change is that I finally came around on the names, and changed from byte-count oriented names to bit-count oriented names. What finally swayed me was some code I wrote that mixed endian typedefs with cstdint typedefs. It was jarring to see both naming conventions intermixed in the same source files. Yet this will be the most common use pattern. So the change has been made. --Beman

I'm happy with the direction boost is going in (if that counts for anything). I look to boost to solve data structure related problems for me where C++ lacks, less so for other things that a full library like POCO can provide. Sohail

CVS notification e-mails

Hi, I currently follow CVS activity through gmane.comp.lib.boost.cvs. Unfortunately for two days now it is completely stopped, and last message I can see there is: RCS file: boost/libs/date_time/xmldoc/exclusive_date_time.xml,v (...) diff -u -d -r1.1 -r1.2 --- exclusive_date_time.xml 8 May 2005 18:55:39 -0000 1.1 +++ exclusive_date_time.xml 20 Jul 2006 15:55:16 -0000 1.2 I wonder if the problem concerns gmane or the mailing list itself (or my news server, or...?). Any clue? Is anyone else experiencing the same issue? -- [ Gennaro Prota, C++ developer for hire ]

My colleague just showed me a very concise example of how he created a service that can be registered with Windows. The same code works for Unix as well. I don't think there are any boost libraries that can do this yet. > -----Original Message----- > From: boost-bounces(a)lists.boost.org > [mailto:boost-bounces@lists.boost.org] On Behalf Of Cliff Green > Sent: Friday, July 21, 2006 3:10 PM > To: boost(a)lists.boost.org > Subject: Re: [boost] ANN: POCO - C++ Portable Components > > I've only quickly scanned the POCO web page, but it > appears that there is quite a bit of overlap with Boost > (and will be even more overlap in the future).
