Thanks for your answer Ben. Apachies offer a search through the mailing lists, which is very useful. I think, I will search using google, which can be practical. One only needs to add the website url at google with the specification where to search as addititional parameter, e.g. regex multibyte site:http://lists.boost.org/boost-users Thanks for your help, again.

Re: [Boost-users] Error building date_time and ICE with multi_index
by Jasper, Alexander 19 Jul '05

Hi! maybe s.th. can be told from the bjam output while building dsate_time. I've attached the output to my previous post. Does it look the some as yours? Or are significant differences that might somehow indicate why I don't have the release mode libs. I've not seen any obvious error messages in there, though. It would be nice if s.o. compared that stuff.

Sorry to disturb you all, I have a very simple question. Is here a functionality to search the archives, or should I use google to search within boost.org? Kind Regards, Ovanes

cvs serialization error
by Chris Coleman 19 Jul '05

19 Jul '05

Hi, While using the boost cvs sources on Mac OS X 10.4.2 I have come across the error below: (I'm using the cvs since 1.32 wont build on 10.4 due to apple? removing one of the gcc compiler flags...) In file included from /usr/local/include/boost/archive/detail/basic_oarchive.hpp:25, from /usr/local/include/boost/archive/detail/oserializer.hpp:58, from /usr/local/include/boost/archive/basic_text_oarchive.hpp:32, from /usr/local/include/boost/archive/text_oarchive.hpp:31, from ./zz_cell_zri.h:28, from ./zz_public_cell.h:27, from ./zz_cell_set.h:21, from ./mantra_response.h:32, from ./mantra_request_abstract.h:26, from mantra_request_admin.h:21, from mantra_request_admin.cpp:16: /usr/local/include/boost/archive/basic_archive.hpp:21:2: error: #error "no serialization headers my precede any archive headers" Cheers Chris This message has been checked for viruses but the contents of an attachment may still contain software viruses, which could damage your computer system: you are advised to perform your own checks.

Phoenix lazy functions
by Edson Tadeu 19 Jul '05

19 Jul '05

I'm trying to learn to use Phoenix, but I haven't found an example of how to do the following simple thing using its inline lazy function creation (it seems that there isn't a simple way to do this): struct Test { int x; void Test() {x = 1;} void inc(int i) { x += i; } }; void main() { vector<Test> v; v.resize(5); // v == {1, 1, 1, 1, 1} for_each(v.begin(), v.end(), arg1.inc(1 + arg1.x) ) // v == {3, 3, 3, 3, 3} } The only ways I found to do this involves function<> that needs an external functor declaration, but this is ugly just like old STL functors, or using member_function_ptr and member_var_ptr templates, but I couldn't get them to work on Borland C++. Anyone knows how to do it, keeping simplicity and elegance? Thanks in advance!

ICE in multi_index - solved
by Jasper, Alexander 18 Jul '05

18 Jul '05

Hi All! I've solved the ICE in VC 7.1 and multi_index: don't use /Gm (ie. "Minimal rebuild") Than it works ok. But I'm still unable to build the release verison of date_time, though. kind regards Alex

Boost warning policy
by Yuval Ronen 18 Jul '05

18 Jul '05

Hi. Is there some "official" Boost warning policy? What I mean is something like: "If you use Boost with VC7.1, then you should work with warning level X, warnings A, B and C enabled, and warning D, E and F disabled. If you work this way, you won't get any warnings from Boost code. If you still do, then it's our bug. Please report it so we can fix it." Is there something like that? I searched the docs, but found nothing of this sort. Thanks, Yuval

Question about the comment in boost::thread condition.hpp

Can anybody shed a light on this? // 23 May 01 WEKEMPF Removed "duration" timed_waits, as they are too // difficult to use with spurious wakeups? I need relative time waits and this comment made me wary. Thanks for your time, Georgi

Lookbehind assertions problem with 1.33
by Gregory Nisnevich 18 Jul '05

18 Jul '05

I'm trying to use lookbehind assertions, and here's a problem: the following syntax (?<=^.{2}).{4} gives me the error: '(?<=^.{2}).{4}' is a bad regular expression: Unmatched [ or [^ while the following works: (?<=^..).{4} matching, as I expected, 4 characters after the first 2 characters in a line. Shouldn't the above two regexes work the same way? Thanks, -Gregory __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
