RE: [Boost-Users] Suggestion -- Boost Building

In my case (the most recent how-can-I-build-this question) I'm trying (unsuccessfully) to use the regex library, which requires compiling.... I used to be able to build this, but since the boost.build stuff came along, I've been completely unable to build anything at all. The documentation is worse than useless because it's so self-contradictory.... -------------------------- John Wismar mailto:jwismar@alldata.com > -----Original Message----- > From: Duane Murphy [mailto:duanemurphy@mac.com] > Sent: Saturday, January 26, 2002 12:15 AM > To: Boost Users > Subject: [Boost-Users] Suggestion -- Boost Building > > > It seems a lot of questions come up on the list about > "building" the boost libraries. > > I wonder how many of these people realize that most of the > functionality of the Boost "libraries" is completely > encapsulated in the header files?

Cannot find regular expression symbols in Solaris debug
by phlasnicek 31 Jan '02

31 Jan '02

Hi, I am using Solaris Workshop 5.0 and I am using boost libraries for regular expressions. Everything builds fine and runs ok except when I try to attach to the process and run the debugger. I get the following error: warning: cannot demangle '__1c9uX__unnamed_6ofsRKVdR8zYNQre_get_error_str6FI_pkc_' Anyone have any suggestions, I would appreciate it very much. Thanks Paul

RE: [Boost-Users] Re: boost::pool + shared memory

I've been using the ACE_Malloc framework from ACE (http://cs.wustl.edu/~schmidt/ACE.html) to solve a similar problem (sharing statics between DLL's). It takes a little while to figure out because the documentation is a little slim, but once you do it pays off pretty quickly. Doxygen documentation for ACE_Malloc is at: http://doc.ece.uci.edu/Doxygen/Current/html/ace/classACE__Malloc__T.html and the shared_mem memory pool is at: http://doc.ece.uci.edu/Doxygen/Current/html/ace/classACE__Shared__Memory__Po ol.html I ended up not having to write an STL allocator using ACE_Malloc, but I don't think it would be too difficult. If you get it right, a lot of ACE users would be your friend :) Tom Matelich > -----Original Message----- > From: xpav_2000 [mailto:alex@pavloff.net] > Sent: Tuesday, January 29, 2002 6:01 PM > To: Boost-Users(a)yahoogroups.com > Subject: [Boost-Users] Re: boost::pool + shared memory > > > --- In Boost-Users@y..., Tom Matelich <tmatelich@z...> wrote: > > Looks like pool may not be what I need, darn.

Hi John, that's what I'm doing now. I just want to fully understand the new jam way of building/using boost, and eg to see what is neccessary to use the 'new way'. Will the 'old way' be deprecated someday? Does/will the new way support static libs? > >And how to link the boost thread stuff? > >Is it supported for statically linked apps at all? > Build threadmon.cpp into a dll, and the rest of the source into a static > lib with the options you want. Okay, thanks, I will try this combination. bye, Bruno

It actually does slow things down noticeably, since it's a small project. > He might be sub setting boost and only wants to include the needed files. Exactly. I have 47 more files checked into source control that everybody else has to download (and have the tool check every time they refresh) so that I can parse a command line. I suppose I could check in the whole boost library, (~2000 files in the download I got,) but I'd rather just take what I need for now. > Anyway, this was brought up during the review, but at the time only 20 files > were needed (the very first tokenizer only need 2 boost headers).

Evidently reviewers thought 20 was reasonable, and I assume that some major problems are solved by the 47 headers that weren't by 20. I just wondered if there was a lighter weight way in boost to do my little tokenizing task. Is there? -- Tony K.

object_pool, O(N) destroy?
by kevin_godden＠agilent.com 29 Jan '02

29 Jan '02

Hi, I am considering using boost::object_pool for fast allocation and deallocation of likkle container/token objects. I need to make this as fast as possible, to this end I wonder why object_pool seems to use boost::pool::ordered_free() (O(N)) rather than the faster free() (O(1))? There must be a reason, but I can't seem to find it in the Lib's documentation. I would be interested in hearing if peoples experiences/comments on using object_pool. Thanks for reading! Kevin\
