Compiling BOOST_1_30_0 UNDER HPUX B.11.11

Hi, I am trying to Install BOOST_1_30_0 on HPUX B.11.11 using aCC Version HP ANSI C++ B3910B A.03.33. Fisrtly i tried to build the thread libaray under <BOOST_ROOT>/lib/thread/build using statement bjam -sTOOLS="acc" -sBuild="debug release" I tried thread first because the regex compilation was also giving problems.

Problem building Boost 1.31.0 for VC6
by Estese 02 May '04

02 May '04

Hi, I'm trying to build the Boost 1.31.0 libraries for VC6 (on WinXP). My installation of MSVC is "C:\Program Files\Microsoft Visual Studio\VC98". All my user environment variables point to this location, as they should. I created the bjam executable, placed it in my Boost root (C:/boost_1_31_0), and then ran bjam with the following command: bjam "-sTools=msvc" However, it attempts to run the following command for every library: "CALL D:\Program Files\Microsoft Visual Studio .NET 2003\VC7\bin\cl" I don't even have .NET installed on my PC! Why would it be doing this? I tried explicitly telling bjam where vc6 is with the -sMSVC_ROOT argument, but it always outputs the same result. I've verified all my user environment variables, and they all point to C: and to VC6, as they should. I don't know why bjam insists on trying to build the boost libraries for Visual Studio .NET. Any thoughts? Sean Estey __________________________________ Do you Yahoo!? Win a $20,000 Career Makeover at Yahoo! HotJobs http://hotjobs.sweepstakes.yahoo.com/careermakeover

serialization library
by Russell Balest 01 May '04

01 May '04

Robert, Thank you for writing the serialization library. I'm in awe that someone finally did this so well. I've been using it for 2 days and think it's fantastic. I've been mucking with serialization frameworks myself for 8 years; now this will trump all my efforts and I'll give up and switch. Many Thanks, Russell Balest

lexical_cast<string> of type char
by DY, JERRY U (SBCSI) 01 May '04

01 May '04

I'm converting our code to use lexical_cast for converting between our numeric types to string. It worked mostly but was surprised to see what looked like graphic characters on my screen. It turns out that when we wanted to display the ascii value of a character, lexical_cast<string> doesn't work -- it doesn't treat the char as a numeric, which when we really think about it, makes a lot of sense. Casting the char to int solves the problem. But I was just wondering how the experts would handle this. char c = 65; string s1 = lexical_cast<string>(c) // s1 = "A" string s2 = lexical_cast<string>((int)c) // s2 = "65" Thanks! -Jerry

string/wstring conversion using lexical_cast
by Tony Djordjevski 30 Apr '04

30 Apr '04

Hi, I'm using Boost 1.31.0 with VC++ 7.1 and I'm having some problems converting std::string to std::wstring and back. Here's the code that I'm trying to get to compile: std::wstring x = boost::lexical_cast<std::wstring>( std::string("this doesn't work")); std::string y = boost::lexical_cast<std::string>( std::wstring(L"neither does this")); The error I get for string to wstring: lexical_cast.hpp(150): error C2679: binary '>>' : no operator found which takes a right-hand operand of type 'std::wstring' (or there is no acceptable conversion) And the errors I get for wstring to string: lexical_cast.hpp(144): error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'const std::basic_string<_Elem,_Traits,_Ax>' (or there is no acceptable conversion) with [ _Elem=wchar_t, _Traits=std::char_traits<wchar_t>, _Ax=std::allocator<wchar_t> ] lexical_cast.hpp(144): error C2228: left of '.fail' must have class/struct/union type Any ideas of what I'm doing wrong?

This is not brain-dead. It is useful to be able to control the order in which symbols are looked for since they may be defined in more than one library. It is a bit weird that -l is not placed before the file names as is the Unix convention for options, but it *isn't* an option - it is a shortcut for specifying a file in the library search path that follows the usual library name convention (lib<name>.a) and is exactly equivalent to specifying the full file name (AFAIK). Secondly, there is no g++ linker. g++ can use various Unix linkers though it is most commonly used together with the linker from GNU binutils. However, all Unix linkers should behave this way. Ben.

Config question: BOOST_NO_INTRINSIC_WCHAR_T (Intel 7.1)
by Christopher D. Russell 30 Apr '04

30 Apr '04

Hello folks, I'm just getting around to upgrade to Boost 1_31_0 from Boost 1_30_0. I'm attempting to use 1_31_0 out-of-the-box (w/no bjam) but am confused about how to resolve problems related to native wchar_t support (or lack thereof). Some details: I'm using MSV6 with the Intel 7.1 compiler. Specifically I'm using: Intel(R) C++ Compiler for 32-bit applications, Version 7.1 Build 20030609Z I added a few #pragma messages to the config headers and have verified that config indeed seems to making the right decisions - at least at a high level: [Boost Configure: Selected Intel Compiler] [Boost Configure: Selected STLport Standard Library] [Boost Configure: Selected Win32 Platform] The specific error I encounter: d:\ENCAPSULE-EXTLIB\boost\boost_1_31_0\boost_1_31_0\boost/type_traits/is_inte gral.hpp(38): error: class "boost::is_integral<unsigned short>" has already been defined BOOST_TT_AUX_BOOL_TRAIT_CV_SPEC1(is_integral,wchar_t,true) ^ d:\ENCAPSULE-EXTLIB\boost\boost_1_31_0\boost_1_31_0\boost/type_traits/is_inte gral.hpp(38): error: class "boost::is_integral<const unsigned short>" has already been defined BOOST_TT_AUX_BOOL_TRAIT_CV_SPEC1(is_integral,wchar_t,true) ^ d:\ENCAPSULE-EXTLIB\boost\boost_1_31_0\boost_1_31_0\boost/type_traits/is_inte gral.hpp(38): error: class "boost::is_integral<volatile unsigned short>" has already been defined BOOST_TT_AUX_BOOL_TRAIT_CV_SPEC1(is_integral,wchar_t,true) ^ d:\ENCAPSULE-EXTLIB\boost\boost_1_31_0\boost_1_31_0\boost/type_traits/is_inte gral.hpp(38): error: class "boost::is_integral<const volatile unsigned short>" has already been defined BOOST_TT_AUX_BOOL_TRAIT_CV_SPEC1(is_integral,wchar_t,true) ^ ... tracked back into .../1_31_0/boost/type_traits/is_integral.hpp #ifndef BOOST_NO_INTRINSIC_WCHAR_T BOOST_TT_AUX_BOOL_TRAIT_CV_SPEC1(is_integral,wchar_t,true) #endif ... where BOOST_NO_INTRINSIC_WCHAR_T is defined in ../1_31_0/boost/config/compiler/intel.hpp // See http://aspn.activestate.com/ASPN/Mail/Message/boost/1614864 #if BOOST_INTEL_CXX_VERSION < 700 # define BOOST_NO_INTRINSIC_WCHAR_T #else // _WCHAR_T_DEFINED is the Win32 spelling // _WCHAR_T is the Linux spelling # if !defined(_WCHAR_T_DEFINED) && !defined(_WCHAR_T) # define BOOST_NO_INTRINSIC_WCHAR_T # endif #endif I read the post on ActiveState but I'm still confused. With the frequency of Intel compiler updates is it possible this particular release is not setting the expected macros correctly? If someone could give me a kick in the right direction I would appreciate it. I really want to try some of these nifty Spirit v1.8 facilities (wow Joel). - Thanks Chris
