Has anyone managed to use boost::function<> with Sun WorkShop 6 update 2? For me, it causes the compiler to core dump. Simon Bailey

RE: [Boost-Users] Linking Problem with GCC

Hi Jeff, I agree that latest problem is possibly an STL/environment problem specifically related to linking a DLL. An exe compiles and links fine. I'm only new to GCC and am using v2.95. I tried updating to the 3.0.4 libraries but that didn't seem to help any. Anyway, I only got into this bind because VC7 and VC6 both run into Internal Compiler Errors when trying to compile (only a select part) of the BGL. I got a work around from Microsoft for one compiler bug, made a fix to the BGL code to get past another, then hit yet another internal compiler error. Where does all this happen? Specifically with examples from the BGL text book including the edge connectivity example in section 8.2. I don't blame the BGL for the bugs in the VC compilers and I guess the remainder of my woes are most likely attributable to my inexperience with the other compilers/environments. It seems, however, that for the code I am tryng to compile atleast, that there is a hurdle at every corner! I'm scared that even if I do get something going Ok, the second I use a new template I'll be in uncharted territory again. Unfortunately I can't afford this kind of risk on a fast track project. Maybe when I have more time, I'll come back to the BGL and try again. Thank you for your kind response. Wayne. -----Original Message----- From: Jeff Garland [mailto:jeff@crystalclearsoftware.com] Sent: Tuesday, April 16, 2002 4:17 PM To: Boost-Users(a)yahoogroups.com Subject: RE: [Boost-Users] Linking Problem with GCC > Hi Jim, > > Yep its boost (BGL - graph) related.

Sure, I've compiled earlier versions of BGL with GCC (of course this proves little since we might have been using different parts). According to the compiler status page the graph test also works under BCC and VC6SP5. http://www.boost.org/status/cs-win32.html Which again doesn't prove much since we don't know the difference in what you are doing from the graph test does. From your previous mail the GCC problems doesn't seem to be a boost problem at all: :\data\software\code\controlled\snowbird\support\hminetworkservices\net worklib\maindll.o(.text$_S_oom_malloc__t23__malloc_alloc_template1i0Ui+0 x1a)://c/data/software/code/controlled/snowbird/support/hminetworkservic es/networklib/maindll.cpp: undefined reference to `endl(ostream &)' c:\data\software\code\controlled\snowbird\support\hminetworkservices\net worklib\maindll.o(.text$_S_oom_malloc__t23__malloc_alloc_template1i0Ui+0 x27)://c/data/software/code/controlled/snowbird/support/hminetworkservic es/networklib/maindll.cpp: undefined reference to `cerr' This looks to be an environment issue because it is complaining about not being able to find standard library components: cerr and endl.

Hi Jim, Yep its boost (BGL - graph) related. (Refer my 3 previous postings 11/4, 12/4 & 12/4). Granted, this particular posting didn't have the word "boost" in it. Like I say. VC7 croaks, VC6 croaks, GCC croaks, Borland (bcc32) croaks. BGL sounds excellent in theory. GTL compiles first time. Has anyone else had a better experience than mine with the BGL?

Regd Boost Graph Library Graphviz interface library...
by rradh 16 Apr '02

16 Apr '02

Hi, On two seperate Solaris 8 multi-processor machines (with sufficient RAM and swap space), the final archive command to create the library for reading/writing the dot format crashes with a segmentation fault: OBJS = graphviz_graph_lex.o graphviz_digraph_lex.o graphviz_digraph_parser.o graphviz_graph_parser.o libbgl-viz.a: $(OBJS) $(AR) -rc libbgl-viz.a $(OBJS) When I ran the 'ar -rc ..' command again prefixed with the 'truss' command, it crashed soon after loading the last .o file. Oddly enough, the archive command worked on a multi-processor Linux machine... Any diagnostics as to why the archive command doesn't work on the Solaris machines? Regards Rajesh

Hi, I wanted to use the Boost Random Library with the Borland C++ 6 Compiler, unfortunately random_test.cpp fails to compile with the message [C++ Error] linear_congruential.hpp(63): E2451 Undefined symbol 'mult_add' I think its an error concerning overload resolution, but i could'nt fix it. Can someone help me? Kind Regards, Andreas Profous

hey friends i am newbie, to this. i have a project to conduct as a part of my final year projec i m stack and i think boost is the way. I am supposed to implement The Clarke and wright savings algorithms using c++ and adjacency list or matrix as a data structure. i ma having problem in this. how can i use boost to asist me with this. i have a C++ compiler how can i incoporate the c++ library with those of boost?, I will be so glad if i find somebody to assist me with details on how to go about implementinng this i will appreciate a quick response as the dead line is approaching. thanks in advance Anael --------------------------------- Do You Yahoo!?

VDB
by Martijn W. van der Lee 15 Apr '02

15 Apr '02

Hi, I've created a small framework I dubbed Virtual DataBase (VDB) which is in actuality a set of three classes which handle tables of data. table<DataT> Manages a random number of records of type DataT, including all memory management. view<DataT> Manages a sorted and/or filtered view of the records in a table. The filter and sort algorithms are supplied through functions or functors and is quite fast (though there's still room for improvement). tracker<DataT> Tracks a single record in a table. If the record is deleted, the tracker becomes invalid. That's basically it. It's built to be generic, simple and reusable. What are the chances of such a framework finding a place in the large Boost library? Currently everything seems to be working based on simple testcases but I'm still working on creating detailed testcases (using my own "Testkit" framework). regards, Martijn van der Lee
