by Ken zhang 02 Dec '08

02 Dec '08

Hi Dear I want use boost::filesystem::wpath for directory operation, It worked fine in VS2005, but I can't compile the same code by code::block + MinGW. The compiler report error below. D:\Development\Tools\boosttest\localization.cpp:14: error: `wpath' is not a member of `boost::filesystem' D:\Development\Tools\boosttest\localization.cpp:14: error: expected `;' before "path" D:\Development\Tools\boosttest\localization.cpp:15: error: `path' was not declared in this scope How can I resolve it ? Is it a bug in MinGW? Thanks -- Best Regards, Kennir

./configure: Permission denied (Mac)

Hi! I am trying to install boost 1.37 on Leopard 10.5.2. I have put boost_1_37_0 in my home directory and I have successfully compiled and executed a header only application. I am following the following instructions: http://www.boost.org/doc/libs/1_37_0/more/getting_started/unix-variants.html When I try to run ./configure --help I get a permission denied error. -bash: ./configure: Permission denied When I say sudo: ./configure sudo: ./configure: command not found The configure file is certainly there. I have even tried to make it readable and writable by everyone. Any ideas? Thanks. -- View this message in context: http://www.nabble.com/.-configure%3A-Permission-denied-%28Mac%29-tp20765691… Sent from the Boost - Users mailing list archive at Nabble.com.

date formatting problem
by Sergey Skorokhodov 01 Dec '08

01 Dec '08

Hi, I'm trying to read dates in "%d%m%Y" (DDMMYYYY). Unfortunately, it doesn't work. Here is the code: #include <string> #include <stdexcept> #include <iostream> #include "boost/date_time/gregorian/gregorian.hpp" using std::string; using namespace boost::gregorian; using boost::date_time::not_a_date_time; using std::cout; using std::cin; using std::endl; using std::locale; int main() { try { date dt( not_a_date_time ); date_facet* facet(new date_facet("%d%m%Y")); cout.imbue( locale( cout.getloc(), facet ) ); cin.imbue( locale( cin.getloc(), facet ) ); cout.exceptions( std::ios_base::failbit ); cin.exceptions( std::ios_base::failbit ); cin >> dt; cout << dt << endl; } catch ( const std::exception& e ) { cout << typeid(e).name() << " " << e.what(); } return 0; } Here program output: > 18111957 > struct boost::gregorian::bad_month Month number is out of range 1..12 If date is assigned programmaticaly, then cout does work as expected and the date output is in %d%m%Y format. I've tried boost 1.33.1 and 1.36 What's wrong with my code? TIA

About boost.mpi and boost 1.35
by Sofia Aparicio Secanellas 01 Dec '08

01 Dec '08

Hello! I want to install boost.mpi on my ubuntu. Using the synaptic I have installed boost 1.35, boost-build and bjam to follow the instructions of http://www.boost.org/doc/libs/1_37_0/doc/html/mpi/getting_started.html#mpi.… They say that I should run "bjam --with-mpi" in the top-level boost directory, but it is not clear for me where is this directory. I try to run this command in every directory where it was something about boost but it didnot work. /usr/include /usr/share/boost-build /usr/share/boost-build/tools The error message that I obtain is: error: no Jamfile in current directory found I have tried to do the same in another computer and in this case I have installed manually boost 1.37 and here it is working. Do you know what is the problem? boost 1.35 supports boost.mpi? Do I need to download boost manually? Thank you very much.

[PROTO] Custom functions, scalar terminal and make_expr vs details::as_expr_if
by Joel Falcou 30 Nov '08

30 Nov '08

I have a large number of custom unary and bin ary function that I map using unary_expr and binary_expr. The problem is the following : my grammar has integral or floating point scalar terminal. So, when I want to create a binary function that takes any elements of my domain, I'm boudn to do the following : template<class L,class R> typename result_of::make_expr<....>::type my_custom_binary_func( L const& l, R const& r ) { return make_expr( ... ); } Alas, as I already discussed with Eric, nothign prevent me to use my_custom_binary_func over types that aren't in my grammar. To do so, I was told to use SFINAE to prune unwanted element by matching the result type of make_expr on my grammar. However, this proves cumbersome and slow down compile time by *a large factor* when I have a large number of such function (and I have like 50 or 60). So i wandered into proto source code and looked at how proto solves this problem for its binary operator. This solution seems more elegant but as it live sin proto::detail, I don't think I'm intended to use it. So, how can I have a simple and fast creation of custom expression ? Am I missing something blatant ? -- ___________________________________________ Joel Falcou - Assistant Professor PARALL Team - LRI - Universite Paris Sud XI Tel : (+33)1 69 15 66 35
