Re: [boost] [modularization] Dependency to Boost.Exceptionunavoidable?

I wonder how useful supporting exceptions disabled is in recent years? Most recent C++ code assumes throwing exceptions works, and even games consoles which traditionally were very anti exceptions are beginning to weaken on this [1]. I also note that the C++ 11 standard library does a lot more exception throwing than the C++ 03 standard library, so it would surely be harder use C++ 11 with exceptions disabled. All this said, LLVM used to not use exceptions nor RTTI, and could be compiled with both disabled. No idea if this is still the case. Either way it was/is an interesting choice by a large, modern, non-embedded C++ use case. [1]: http://www.gamedev.net/topic/639123-portable-use-and-disabling-of-exceptions Niall

Concatenating int value to string ..??
by Rahul Mathur 02 Nov '13

02 Nov '13

All, I wish to have string (combination of string value and int value) which increments until 100. The code is as below - --- #include <iostream> #include <cstdlib> #include <string> #include <boost/lexical_cast.hpp> using namespace std; int main() { std::string TID = "Apple"; int TagID = 01, Value = 000 /* 100 IDs*/; std::string TagName, TagInitial, TagUId; TagName = TID + boost::lexical_cast<std::string>(TagID); // Should be as -> Apple01 TagInitial = TagName + boost::lexical_cast<std::string>(Value); // Should be as -> Apple01000 int i = boost::lexical_cast<int>(TagInitial) + 1; // Should be as -> Apple01001 TagUId = boost::lexical_cast<std::string>(i); std::cout << "Tag ID .." << TagUId << endl; } I get below error message - -- terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::bad_lexical_cast> >' what(): bad lexical cast: source type value could not be interpreted as target Aborted (core dumped) -- Any clue? ~ Thanks!!

[Trac] Catch-22: Captcha Errors on legitimate submissions
by Jim Bell 01 Nov '13

01 Nov '13

I had a ticket attachment and comment both rejected from a "captcha error," so I decided to open a Trac ticket on the captcha mechanism itself. But guess what? THAT ticket was also rejected by the captcha error. Catch-22! So I'm posting it here. I get: -------------------------------- Captcha Error Submission rejected as potential spam (StopForumSpam says this is spam (username)) Trac thinks your submission might be Spam. To prove otherwise please provide a response to the following. -------------------------------- But there's nothing following to which to provide a response. Is it mis-configured?

[modularization] Dependency to Boost.Exception unavoidable?
by Daniel Pfeifer 01 Nov '13

01 Nov '13

2013/11/1 Peter Dimov <lists(a)pdimov.com>: > > ->exception is unavoidable because of throw_exception. I think `throw_exception.hpp` belongs to Boost.Utility for two reasons: 1. That file is older than Boost.Exception. 2. It introduces a *conditional* dependency to Boost.Exception. When I provide an implementation for `throw_exception` and/or define BOOST_NO_EXCEPTIONS/BOOST_EXCEPTION_DISABLE accordingly, I would expect *not* having a dependency to Boost.Exception. -- Daniel

[config] including typeinfo in dinkumware.hpp when RTTI is disabled
by Edward Diener 01 Nov '13

01 Nov '13

Evidently the only way to currently compile clang on Windows using the VC++ RTL is to compile without RTTI and exception handling in its VC++ emulation ( options -D_HAS_EXCEPTIONS=0 /GR- ). This may be totally unrealistic for Boost. Nonetheless with these compiler options, when the dinkumware.hpp is being used by Boost config, it is including typeinfo and this is causing a problem: c:\Program Files\Microsoft Visual Studio 10.0\VC\INCLUDE\typeinfo(156,10) : error: unknown class name 'exception'; did you mean '_exception'? : public exception Is it realistic in dinkumware.hpp to not include typeinfo if RTTI is not enabled ? Or is it just more realistic to say that compiling Boost libraries with RTTI disabled is not going to work ?
