Building with Comeau
by Dale Peakall 12 Oct '01

12 Oct '01

Anyone had any success using the new build system with Comeau C++ on Win32 (MSVC6)? I'm using the pre-compiled Win32 jam binary from the FreeType project. Is this still suitable? I noticed Dave has checked in a whole bunch of changes to SourceForge. If not, is there an easy way to get the whole branch out of CVS? I've only ever used the web-interface which doesn't seem to provide this facility. The first problem I encountered was jam trying to use mv. After replacing the $(MV) instructions in the como-tools.jam with copy, I managed to get some obj files produced, but none of the libraries will link. First up, I noticed that the build system requires libcomo to be in a certain location, so I fixed that, but still nothing will link (lots of undefined external symbols - some to boost, some to std). I'm a Comeau newbie, so I may have messed up building libcomo (which would explain the missing std symbols), but not the missing boost symbols. Cheers, - Dale.

Thread Summary Experiment -- on the Wiki
by Jeff Garland 08 Oct '01

08 Oct '01

Last week we were having a discussion about the sort of content that might, or might not belong on the Wiki. I have tried another small experiment that might be a useful approach to augmenting the current boost information. The idea is to build a summary of mailing list discussion threads related to each library (or other topics). Many of the discussion on the mailing list can provide insight into the library design as well as solutions to specific problems not necessarily incorporated in the documentation. I built a small example for the function library. http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?Function_Lib… -_Mail_Thread_Summary I have used the following convention for this: -- Order the thread names by date -- Title of the thread is either the email title, or a more precise title followed by the original thread title in parens The link performs a search that returns all the items in the thread from the yahoo groups site. One problem is that since the search is full text, some threads cannot be easily retrieved. For example searching "function review" will return a pile of email on threads and other topics unrelated to function. Despite the issues, this would seem to me this would be a useful contribution library users could build. Thoughts? Jeff

concept_check and B&N trick
by Eric Ford 03 Oct '01

03 Oct '01

I ran into problems using BOOST_CLASS_REQUIRES in conjunction with the base class in the Barton-Nackman trick/Curiously recursive template technique. I want to require functions that take the derived type as an argument. So I declare a variable of the derived at struct level in the concept class, but then g++ (2.95) complains about it being an invalid use of undefined type... forward declaration... . Is there a way to make this work? If so, does anyone have/know of an example I can see how to order things to make it work? Thanks, E

Building regex/1.25.0 with MSVC6SP5, STLPort 4.0
by Markus Schöpflin 02 Oct '01

Hi there, I've been trying to build the regex library but failed miserably. The compiler always dies with an error in "regex_traits.hpp" C:\boost_1_25_0\libs\regex\build>nmake INCLUDES="-I%STL_INCLUDE%" -fvc6-stlport.mak Microsoft (R) Program Maintenance Utility Version 6.00.8168.0 Copyright (C) Microsoft Corp 1988-1998.

The error stays the same if I try the new build system with the following command line: jam -ftools/build/allyourbase.jam -sTOOLS="msvc" -sBUILD="<include>%STL_INCLUDE%" If I look at the offending line in "regex_traits.hpp" it reads const std::ctype<char>* pctype; Obviously it doesn't know that ctype lives in the std namespace. It works if I use the STL supplied by Microsoft. Does anyone else use this combination of compiler and library and managed to successfully build the regex library? Markus 'mar

I don't use STLPort, but you might try a slight modification to boost/config/suffix.hpp. Search for BOOST_NO_STDC_NAMESPACE, and you'll see the line: namespace std { using ::ptrdiff_t; using ::size_t; } Try adding "using ::ctype;" into the list of using declarations. This may not work, though; I don't know if a using declaration can nominate the name of a template. -- Jim
