Building 32-bit on linux x86-64?
by Nicholas Bastin 18 May '07

18 May '07

I have a linux machine on x86-64 that I'm trying to use to build Boost in 32-bit. I can build other source in 32-bit, so I figure my environment is set up correctly unless Boost needs something I'm not thinking of. I executed bjam as: bjam --toolset=gcc address-model=32 --with-signals stage Everything builds fine, but the libs aren't 32-bit, file says: libboost_signals-gcc34.so: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), stripped Any ideas? -- Nick

Hi, When using precompiled headers, BOOST_TYPEOF_REGISTER_TYPE() macro throw some erros. stdafx.h: --- #pragma once #ifndef _WIN32_WINNT // Allow use of features specific to Windows XP or later. #define _WIN32_WINNT 0x0501 // Change this to the appropriate value to target other versions of Windows. #endif #include <boost/typeof/typeof.hpp> --- test_boost_auto.cpp : --- #include "stdafx.h" // 1 //#include <boost/typeof/typeof.hpp> // 2 #include BOOST_TYPEOF_INCREMENT_REGISTRATION_GROUP() class A { }; BOOST_TYPEOF_REGISTER_TYPE(A) int main() { return 0; } --- When "USE precompiled headers" is turned on, the above code return this error when compiled: --- ------ Build started: Project: test_boost_auto, Configuration: Debug Win32 ------ Compiling... test_boost_auto.cpp d:\temp\delete\test_boost_auto\test_boost_auto.cpp(9) : error C2143: syntax error : missing ';' before '<' d:\temp\delete\test_boost_auto\test_boost_auto.cpp(9) : error C2059: syntax error : '<' d:\temp\delete\test_boost_auto\test_boost_auto.cpp(9) : error C2653: 'a' : is not a class or namespace name d:\temp\delete\test_boost_auto\test_boost_auto.cpp(9) : error C2065: 'V' : undeclared identifier d:\temp\delete\test_boost_auto\test_boost_auto.cpp(9) : error C2143: syntax error : missing ';' before '{' d:\temp\delete\test_boost_auto\test_boost_auto.cpp(9) : error C2447: '{' : missing function header (old-style formal list?) d:\temp\delete\test_boost_auto\test_boost_auto.cpp(9) : error C2143: syntax error : missing ';' before '<' d:\temp\delete\test_boost_auto\test_boost_auto.cpp(9) : error C2059: syntax error : '<' d:\temp\delete\test_boost_auto\test_boost_auto.cpp(9) : error C2143: syntax error : missing ';' before '{' d:\temp\delete\test_boost_auto\test_boost_auto.cpp(9) : error C2447: '{' : missing function header (old-style formal list?)

[boost::filesystem] Directory iteration and doc inconsistencies...
by Ovanes Markarian 18 May '07

18 May '07

Hello! Using boost 1.34 with VC 8 Express Edition and the documentation pointing to: http://www.boost.org/libs/filesystem/doc/tr2_proposal.html#basic_path-itera… I would like to ask following: the doc states: 1. For any other iterator value a const basic_directory_entry<Path>& is returned. [...] For any other iterator value a const basic_directory_entry<Path>* is returned. In my case a string_type is returned. 2. "Directory iteration shall not yield directory entries for the current (dot) and parent (dot dot) directories." In my case begin() points to the current (dot) directory. Are these features not implemented in the current 1.34 release? Debugger shows the following type returned by begin().operator->():  FUNCTION CALL: boost::iterator_facade<boost::filesystem::basic_path<std::basic_string<char,std::char_traits<char>,std::allocator<char> >,boost::filesystem::path_traits>::iterator,std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,boost::bidirectional_traversal_tag,std::basic_string<char,std::char_traits<char>,std::allocator<char> > const &,int>::operator-> returned VALUE: "." TYPE: const std::basic_string<char,std::char_traits<char>,std::allocator<char> > * operator* returns the reference to std::basic_string<char,std::char_traits<char>,std::allocator<char> > With Kind Regards, Ovanes

[boost::program_options] Modification of values after the parsing process
by Ovanes Markarian 18 May '07

18 May '07

Hello! I would like to transform (add) some options after the parsing process has finished. Unfortunately variables_map has no non const members which could acomplish this task. Doing const_cast or using std::map interface, which is not explicitly described as parent class of variables_map is not my first choice. Is there any other way of adding some options programmatically? Many thanks, Ovanes Markarian

> I've tried your code and it gives me this internal compiler error: > [...] > But this code gives me another compiler error (the one I have posted in my > threads) and compiler crash: > [...] I think the bottom line is -- sizeof() is broken with regards to default parameters (possibly in more then one way). As I might have mentioned before any ICE is just a fancy way of saying "compiler bug", let alone compiler crash. As I said, Boost.Typeof is implemented through sizeof(), so all the sizeof() problems unfortunately show up in typeof, and it seems to be no way around it inside the library. We've seen some of those in different compilers and in different contexts. You just discovered one more place where it's broken. The only workaround I can see for you is to pass the default parameter explicitely. Annoying, but I don't see any other way :( > Should I also open the bug for VS 8? Yes, absolutely, unless it's already a known issue. Regards, Arkadiy

[1.34.0] MSVC - How to build Boost without native wchar_t support
by Jochen Hammann 18 May '07

18 May '07

Hello, I'm using the Microsoft Visual C++ 7.1 and 8.0 compilers and I want to build Boost 1.34.0 without native wchar_t support. With Boost 1.32.0 I used the feature <native-wchar_t> to turn off the native wchar_t support of the Microsoft compilers. It seams that this feature isn't supported by the MSVC toolset any more. Is it possible to turn off the native wchar_t support within the command line of bjam? Many thanks, Jochen.
