Library naming conventions
by bkash 15 Nov '07

Hi, Can anyone explain why some libraries created and installed by the build process do not have the boost version number in their names as mentioned in the getting started document? This causes a problem when I build 1_34_1 and install it to the default C:\Boost directory. I have 1_33_1 installed there for projects that will not be updated soon. The 1_34_1 build/install copies files such as boost_date_time-vc71-mt.lib. These files already exist as created by the 1_33_1 build. The file is identical to boost_date_time-vc71-mt-1_34_1.lib, so would imagine I could simply ignore it as long as the automatic linking feature would never use it. The same occurs on linux. For instance libboost_date_time-gcc32-1_34_1.a is identical to libboost_date_time-gcc32.a Thanks, bkash

Strange (wrong?) behavior of boost::regex_replace()
by Peter Klotz 15 Nov '07

15 Nov '07

The program below gives different output in Boost 1.32.0 compared to 1.33.1 and 1.34.1. In my opinion "R_Test" would be the correct result and therefore Boost 1.33.1 and 1.34.1 would be wrong. Can anyone clarify this issue? Best regards, Peter. #include <iostream> #include <boost/regex.hpp> int main() { // Boost 1.32.0: "R_Test" // Boost 1.33.1 and 1.34.1: "R_TestR_" std::cout << boost::regex_replace(std::string("Test"),boost::regex("(.*)"),"R_$1") << std::endl; return 0; }

[gil] Cannot read jpeg file
by Christian Henning 14 Nov '07

14 Nov '07

Hi there, this is most likely off-topic. But I'm a little desperate, though please excuse me. I try to load a jpeg file using gil's io extension. But it always fails. Every time when I try to execute jpeg_read_header my app crashes due to some memory exception. At this point the file is already open and yes, it's jpeg file. I'm using Visual Studio 2005 with plenty of memory. Does anyone has any idea? It must be something really simple but I can't see right now. Thanks, Christian

Olivier, I did my tests with boost 1.34.1 and VC Express 2005. Can you try at least with the version 1.34.1 of boost and your current compiler?

[iterator] readable and writable transform_iterator
by Chris Weed 14 Nov '07

14 Nov '07

I can't figure out how to make a writable transform_iterator work. Here is what I have: #include <boost/iterator/transform_iterator.hpp> #include <boost/tuple/tuple.hpp> #include <vector> template< int N > struct Get { template<typename T> struct result; template<int M,typename T> struct result<Get<M>(T&)> { typedef typename boost::reference_wrapper<typename boost::tuples::element<M,T>::type>::type type; }; template<typename Tup> typename result<Get<N>(Tup&)>::type operator()(Tup& t) { return boost::tuples::get<N>(t); } }; int main() { std::vector<boost::tuple<int,float> > v1; v1.push_back(boost::make_tuple(1,2.2f)); v1.push_back(boost::make_tuple(2,3.2f)); std::vector<boost::tuple<int,float> > v2(2); std::copy(boost::make_transform_iterator(v1.begin(),Get<0>()), boost::make_transform_iterator(v1.end(),Get<0>()), boost::make_transform_iterator(v2.begin(),Get<0>())); } g++ seems to get hung up on figuring out the result type of Get<0>. Any help would be greatly appreciated. Chris

"Getting Started" document : missing documentation of the stdlib flag (fwd)
by Vincent Torri 14 Nov '07

14 Nov '07

Hello, no news about that request ? thank you Vincent Torri ---------- Forwarded message ---------- Date: Sat, 3 Nov 2007 11:15:13 +0100 (CET) From: Vincent Torri <vtorri(a)univ-evry.fr> To: boost-users(a)lists.boost.org Subject: "Getting Started" document : missing documentation of the stdlib flag Hello, If I'm not mistaken, to compile boost with STLport, one must pass -stdlib=stlport (or something like that) to bjam. But it's not mentionned in the "Getiing Started" documentation (Unix or Windows), while STLport itself is mentioned. Also, stdlib is mentioned when I launch bjam with --help, --help-options or --help-internal. Can someone add the documentation of the stdlib flag in "Getting Started", please ? (and maybe also in the boost build, to get doc with bjam --help) Thank you Vincent Torri

Fwd: bind, template member function and thread

On 11/13/07, Olivier Tournaire <olitour(a)gmail.com> wrote: > > Yep, that what I tried, but it does not work. The compiler error is > described below. This is really strange. This code compiles fine: typedef bool (Profile::*mem_fcn)(boost::shared_ptr< TTImage <unsigned char> >, eInterpolatorType); mem_fcn f = &Profile::template ComputeRadiometries<unsigned char>; and the doc example states for member functions: boost::function<int (X*, int)> f; f = &X::foo; X x; f(&x, 5); But I also got errors.

Is Anyone going to tell me the way to Build BOOST?
by question boost 14 Nov '07

Hi, at boost root directory i do: C:\Program Files\boost> bjam ^More? --build-dir=C:\Program Files\boost \directory_1 ^More? --toolset=gcc stage the error message is the following :could not find main target assuming it's a name of a file to create could not find main target C:\Program Files\boost \directory_1 assuming it's a name of a file to create... note:C:\Program Files\boost is my boost root directory, stage a subdirectory of directory_1 Be very clear THANK YOU, David _________________________________________________________________ Découvrez le blog Messenger Le Meilleur du Web : toutes les vidéos qui buzzent le plus sur Internet ! http://meilleurduweb.spaces.live.com/
