certain headers missing
by Dragos Sbarlea 21 Aug '07

21 Aug '07

Hello! I am a new Boost user and my question might seem dumb, but please try to help me. I installed boost and I can run the example posted on the boost getting started page successfully, but when I try to use Boost.Process i get an error that the header fiel does not exist. Looking in the boost include files, i see there is no such file as process.hpp and no folder called process ... Where do I do something wrong? (working on Linux with boost from ubuntu 7.04 repos) Thank you for your time! ____________________________________________________________________________________ Be a better Heartthrob.

heres the code. template <class T> class next { public: next(const int& k) : k_(k), count(0) {} std::complex<T> operator()() { return std::complex<T>(((2.0*PI*k_/Random::randint(k_, 2*k_))*(++count)), 0); } private: static const double PI = 3.141592654; int k_; int count; }; when i tried to do boost::assign::list_of<std::complex<T> >.repeat_func(num_elems, next<T>(num_elems)); I get an error about insuffiecnet contextual information to determine type.

[boost.iostream & Boost Windows Installer 1.34.1] Trouble during linking
by Marc Viala 20 Aug '07

20 Aug '07

Hi, I've recently downloaded the new Boost 1.34.1 Windows Installer and tried to use it but I've met some linking troubles in conjunction with Boost.Iostream & Zlib compression scheme. To explain that, I've just tried to compile w/ VC++7.1 this code snippet: #include <boost/iostreams/filtering_streambuf.hpp> #include <boost/iostreams/copy.hpp> #include <boost/iostreams/filter/gzip.hpp> #include <iostream> #include <sstream> namespace io = boost::iostreams ; // Zlib compression void compress(std::istream& is, std::ostream& os) { io::filtering_streambuf<io::output> out ; out.push(io::gzip_compressor()) ; out.push(os) ; io::copy(is, out) ; } void main() { } The VC++ linker complains that "boost_zlib-vc71-mt-gd-1_34_1.lib" library can't be opened from the Boost installation library path. I've checked it and didn't find any "boost_zlib*" library in the distribution. I've read the "Getting started documentation" and I've found "no specific configuration" for Boost.Iostream with Zlib. I've surely missed something but... I've also went through the boost user-list archive unsuccessfully. Any help or suggestion will be welcomed Marc Viala

boost bind beginner throw problem
by Taglioretti Roberto 20 Aug '07

Hi, I have a problem with boot bind, in a my class there is this member: void test(int i) throw(Error); If I use bind(&test,obj,_1); I have a compilation error, instead if I change the member in void test(int i); all it works. Could someone help me to use bind with my original member ? I do not understand where is the problem. Thanks SO: windows XP SP2 compiler: VC 7.1 boot version: 1.34.1 -- Roberto *sono affetto da discromatopsia, per favore evitate l'invio di mail o allegati colorati* *I have dyschromatopsia, please do not send coloured text or email and attach*

ICU and Boost Regex
by Sudarshan Gaikaiwari 20 Aug '07

20 Aug '07

Hello Boost Experts I am trying to use Boost Regex to replace the java.util.regex package. I want to use the Unicode Regular Expressions and need to link with the ICU libraries. However I want to keep the size of my program as small as possible. What components of ICU are essential for Boost regex? What is the ICU configuration that would lead to the smallest ICU binaries that can still be usable by Boost regex? Thanks regards Sudarshan -- Sudarshan Gaikaiwari www.sudarshan.org sudarshan(a)acm.org

serialization - portability
by Stefaan 20 Aug '07

20 Aug '07

Hi! I'm having an issue with archive portability. As I'm quite new to the internals of boost, I hope my attempt at pinpointing the problem is sensible: #include <iostream> #include <boost/serialization/vector.hpp> int main() { std::cerr << boost::serialization::implementation_level <std::vector <long long> >::value << std::endl; return 0; } built on a x86_64 platform prints out "3", on a i386 platform it prints out "2". I tested this both with boost 1.33.1 and 1.34.1. It is my guess that it causes the serialization of the used type to result in a larger archive on x86_64 than on i386. (Which is the original problem that led me to discover this) So my question is: is this the result of a bug in boost? If not, then what is the explanation of this difference? Using linux-2.6 with gcc. Thanks, Stefaan

Still cannot cross-build boost libs
by Bruce Reid 20 Aug '07

20 Aug '07

I am trying to use linux-x86 platform to cross-build for linux-ppc. I have followed Vladimir’s suggestion to specify my cross-compiler/archiver by updating user-config.jam with: using gcc : : /path/to/my/linux-ppc-g++ : <archiver>/path/to/my/linux-ppc-ar ; I have confirmed this works IF I build one of the [header-only] example programs. This proves that user-config.jam (located in my home directory) is being found, and the compiler/archiver are specified correctly, since the resulting executable runs on the correct target (ppc) platform. However, when attempting to apply the same user-config.jam file to build boost/serialization, it appears my cross-compiler/archiver directives are ignored, and the resulting libraries are in the native x86 format, since attempting to build a program with one of them using my ppc-g++ compiler produces a spew of link errors. Modifying my makefile to use the native g++ compiler permits a successful linkage with the boost/serialization library, and the resulting executable runs fine on the x86 platform. The command I used to build boost/serialization is: bjam --toolset=gcc --with-serialization --prefix=/my/prefix/path --exec-prefix=/my/exec-prefix/path/linux_ppc --libdir=/my/exec-prefix/path/linux_ppc/lib install I also saved the output from the build, but can’t see any clues to explain where things went wrong. Any ideas why I seem to be so close, but still cannot produce boost library binaries for the desired target platform?
