Re: [Boost-users] Running boost::thread compiled on w2k on XP

Hi > Is it impossible to compile the boost libraries on > windows 2000 and then expect the created dll:s to work on windows XP? No. It is not impossible. We have done exactly that without any problem at all. We didn't have to do anything special either. We used VC7.1 on Windows 2000, just as you are. I know that's not much practiacl help, but at least you now know it can be done.

Running boost::thread compiled on w2k on XP
by Ragnar Ouchterlony 29 Jul '04

29 Jul '04

I have tried compiled boost::thread for windows using visual c++ from the visual studio .net 2003 suite. It compiles fine and I can compile things with the created libraries. However, when I move my program and the boost::thread dll:s from windows 2000 to another machine running windows XP, the program just prints out a blank line and exits without any other message. Attached is a program I have used to test out that it is this that is wrong. What have I done wrong? Is it impossible to compile the boost libraries on windows 2000 and then expect the created dll:s to work on windows XP? If this is the case, where can I get hold of the boost::thread libraries for vc71 compiled specifically for windows XP? If not, what could be wrong? /Ragnar Ouchterlony

uBLAS syntax issues
by Nicholas Andrews 29 Jul '04

29 Jul '04

Here's the formula I want to reproduce in uBLAS: K=P*Mt*(M*P*Mt+R)^-1 Where K, P, M, and R are matrices, and Mt is the transpose of M. I have written the following function: void multi_state_kf::compute_gain(const matrix<double>& dev) { matrix<double> temp=prod(M,newP); matrix<double> transM=trans(M); matrix<double> A=(prod(temp,transM)+dev); permutation_matrix<size_t> pm(A.size2()); lu_factorize(A, pm); matrix<double> el = prod(newP,transM); lu_substitute(A, pm, el); K=el; } This function was completely hacked together as I'm new to uBLAS (and rusty with linear algebra), but it got rid of most of my compile errors. Now only a few remain but I'm not sure what I'm doing wrong. I'm hoping that it will be obvious to someone here. Thanks for your help, Nick

Assign and MultiArray conflict with precompiled headers
by Bruno Martínez Aguerre 28 Jul '04

28 Jul '04

Hi. I'm trying out the recently accepted Assign library, and also the MultiArray library, which is new to me. I'm in VC7.1, and using the post review version of Assign. Depending on the order I include the libraries in my precompiled header, the linker complains about double definition of MultiArray's extents object. Here are the files that reproduce the problem. //stdafx.h #pragma once #include "boost/multi_array.hpp" #include "boost/assign.hpp" //main.cpp #include "stdafx.h" int main() { boost::multi_array<int, 2> t(boost::extents[3][4]); } I couldn't find relation between the two libraries. Thanks in advance, Bruno Martínez

Date Time lib and time_t
by Matt Schuckmann 28 Jul '04

28 Jul '04

Has anybody ever implimented a to_time_t function/method for the ptime class to create a time_t from a ptime. I tried doing it similar to the way from_time_t does it but I'm not getting the right answer. It's nice that you can convert from a time_t for use with legacy code but sometimes you need to go back the other way. Herer is my to_time_t function that does not appear to be working inline std::time_t to_time_t(ptime t) { if( t == neg_infin ) return 0; else if( t == pos_infin ) return LONG_MAX; ptime start(gregorian::date(1970,1,1),time_duration(0,0,0)); return (t-start).total_seconds(); } Thanks,

This also isn't exactly what you are looking for, but I took built your test.cpp on vc7.1 running on windows XP using boost 1.31 (also built with vc7.1 running on windows XP). Both the debug (using boost_thread-vc71-mt-gd-1_31.dll) and the release (using boost_thread-vc71-mt-1_31.dll) builds of test.cpp worked fine. My boost dlls were built with all default settings (except I used the alternate namespace hack for boost::signals since we also use Qt). I don't have a boost 1.31 built on win2k to try. > >Perhaps I should add that I am using version 1.31 of boost.

[boost.build] Patch for python.jam
by Markus Schöpflin 28 Jul '04

28 Jul '04

Hello, attached is a patch for pyhton.jam which allows to use python installation on Unix which have been configured with different prefix and exec-prefix. Currently this is not supported by boost.build. The patch simply adds the missing include directory to the compiler command line as recommended in http://www.python.org/doc/2.3.4/api/includes.html . After applying the patch you can either use bjam -sPYTHON_ROOT=<prefix> or bjam -sPYTHON_ROOT=<prefix> -sPYTHON_EXEC_ROOT=<exec prefix> Markus --- net/src/orig/boost_1_31_0/tools/build/v1/python.jam 2004-01-28 23:52:25.000000000 +0100 +++ local/src/boost_1_31_0/tools/build/v1/python.jam 2004-07-28 16:15:37.000000000 +0200 @@ -118,7 +118,7 @@ { PYTHON_ROOT ?= /usr/local ; PYTHON_ROOT = $(PYTHON_ROOT:J=" ") ; - PYTHON_INCLUDES ?= $(PYTHON_ROOT)/include/python$(PYTHON_VERSION) ; + PYTHON_INCLUDES ?= $(PYTHON_ROOT)/include/python$(PYTHON_VERSION) $(PYTHON_EXEC_ROOT)/include/python$(PYTHON_VERSION) ; PYTHON_LIB_PATH ?= $(PYTHON_ROOT)/lib/python$(PYTHON_VERSION)/config ; PYTHON_PROPERTIES ?=

I would also like to use the bjam tool as our standard build tool, but I FIRST need to figure out how to build projects with it (grin). Thanks to anyone for thoughts or things to try.
