ublas: conversion looses qualifiers

A newbie question: I have: void foo(matrix<double>& Y, const matrix<double>& X) { ... Y[0] = X[0]; // the compiler chokes on this ... } What is wrong with this? Please tell me. Thank you. Roland

RE: [Boost-Users] Intel 7.0 Compiler problems

Hmm, I'm not a very good evaluator I guess, I just went about my business using 7.0 without seeing if it worked correctly :) Rather than hacking ICL, you can modify boost/compiler/intel.hpp changing 600's to 700's. I have my own dsp's for building regex, so the Compiler Selection feature worked for me (Though I've renamed cl.exe to make sure its never called because it was getting called sometimes) This is not to say I haven't had any troubles, but none with boost until the subject of my post a few minutes ago. > -----Original Message----- > From: klapshin <klapshin(a)yahoo.com> [mailto:klapshin@yahoo.com] > Sent: Wednesday, February 05, 2003 5:06 PM > To: Boost-Users(a)yahoogroups.com > Subject: [Boost-Users] Intel 7.0 Compiler problems > > > Hello, > > > > > Tired of MSVC deficiencies, and hoping to get certain performance > increase I got evaluation version of Intel C++ compiler.

BGL: BFSVisitor::cycle_edge() ?
by Tarjei Knapstad 06 Feb '03

06 Feb '03

This probably is an error in the documentation (and the book), but I thought I'd just check to make sure: The documentation for the EventVisitor concept states: <quote> For example, the BFSVisitor of breadth_first_search() has a cycle_edge() member function. The corresponding tag is on_cycle_edge. </quote> As far as I can see BFSVisitor has no cycle_edge() function, and there is no on_cycle_edge tag in the code. The same function is also mentioned in chapter 12.3.1 of the book in the documentation of gray_target(e,g) and black_target(e,g) where it says that "A call to this function is always preceded by a call to the cycle_edge() function.". Kind of strange as the cycle_edge() function is not documented in the same chapter :) Regards, Tarjei

Under Linux Red Hat 8.1 Beta the lastest ICC/IA32 0.78 works without problems with boost regex 1.29. I just copiend over the libs/regex/build/ gcc.mak and gcc-shared.mak files to icc*.mak and changed the compiler name within to icc. Under RH8.0 I had some problems because the compiler chooked about the header containing the declarations for some tcp/ip data conversion functions htons() etc.. I've never used the bjam stuff up to now. Perhaps you can do the same with the regex vc7.mak file as a starting point. with best regards, Bruno -- bruno(a)ic3s.de [Non-text portions of this message have been removed]

Intel 7.0 Compiler problems
by klapshin <klapshin＠yahoo.com> 06 Feb '03

06 Feb '03

Hello, Tired of MSVC deficiencies, and hoping to get certain performance increase I got evaluation version of Intel C++ compiler. I've heard lots of good things about this compiler, and was under impression that transition from MSVC to ICL should be very smooth. Huh, I had all kinds of troubles. First of all boost 1.29 gave up saying that it is an unknown compiler. Looking into config I figured that last known ICL was 6.0, so I just hacked it badly by redefining ICL as 600 prior to including any boost headers. I understand that it is not a good way, but hey, I am just evaluating it. Ok now everything compiled, but code using regex failed to link. No wonder, I have not build regex library with new compiler. It turns out that there is no makefile for any intel compiler, so I tried to do it with bjam, but seems that bjam did not set CC variable; it invoked compilation with just line of flags. At this point I gave up and decided to focus on parts of my project which do not depend on regex. Next surprise was when I tried to run tests, in debug mode everything was fine, but release mode failed miserably. It appears that date_time library does not work at all with optimization. Even setting /O1 did not help, only /Od worked. Failures were in very basic date operations, for instance boost::gregorian::date(2002,12,27) == boost::gregorian::date(2002,12,27) is not true! If I first construct a date, then ask for year, it throws, saying year is out of range. I searched through Boost Users and Dev mailing lists, found few posts discussing turning on strict ansi checks on intel, and also that in this case it is better to use STLport, since STL coming with MSVC could not be compiled in ansi mode. I tried to do that but can't compile STLport in strict mode either. Using STLport in regular mode did not have any effect on problems I am having. Here is version the compiler reports: Intel(R) C++ Compiler for 32-bit applications, Version 7.0 Build 20021018Z Copyright (C) 1985-2002 Intel Corporation. All rights reserved. Now, my question is: are these problems well known? If they are, is there any plans to fix them in next release? And while we at it, when should we expect new release? I know there were some discussions about mid-February, is there any update? Regards, Kirill.

HP, aCC and the standards
by dlux42 <dlux＠spam.sch.bme.hu> 05 Feb '03

05 Feb '03

Hello Guys! I am now fighting with HP to recognize that their compiler is buggy. I am one of their customer and would like to get help with this fight. I want to use the boost.org format and regex libraries on HP-UX 11.00 with aCC, and I got contacted the local HP office about that. I told that I want to use modern libraries like the "boost.org" library. They answered that the HP aCC is the implementation of the ISO/IEC 14882 standard of the C++ language. They provided two links about the compiler: http://www.software.hp.com/DTDC_products_list.html (follow the aC++ link). http://docs.hp.com/hpux/onlinedocs/2213/libs.htm#slIntro (introductionary concepts). Do you have any evidence that the HP implementation of C++ language breaks the standard and that's why the regex library and format library does not compile on those platform? (if you need sample error message, then I can send it to the list). I am using stlport 4.5-119, aCC A.03.33. Please Cc: the replies to my private email-address also. Thanks for your help in advance, dLux
