boost.function with CW 8.2 on W2k
by Bertolt Mildner 12 Sep '02

12 Sep '02

I get the following warnings when I use boost::function with CW 8.2 on W2k: Warning : variable / argument 'deprecated' is not used in function (included from: function10.hpp:28 function.hpp:37 Test.cpp:8) function_template.hpp line 388 BOOST_FUNCTION_DEPRECATED_INNER Warning : variable / argument 'deprecated' is not used in function function.hpp line 874 BOOST_FUNCTION_DEPRECATED_INNER Warning : variable / argument 'deprecated' is not used in function function.hpp line 867 BOOST_FUNCTION_DEPRECATED_INNER I'm using a relatively new CVS snapshot (<2 days old). -- Free Crypto Token - FCT www.FreeCryptoToken.org

bjam on hpux
by Glen Knowles 11 Sep '02

11 Sep '02

I'm trying to build boost on hp/ux 11.11 with the aCC 3.35 compiler but can't seem to get a working jam. My tools tell me that the bjam.gz binary for hp/ux is not a valid gzip file and my attempts to compile jam result in a large number of errors which I can get into if needed. Could someone verify that the hp/ux bjam.gz is good? Any help is appreciated, Glen

My problem was that the bjam.gz wasn't a .gz after all. We'll see how much futher I get. Thanks, Glen [Non-text portions of this message have been removed]

BOOST_MSVC6_MEMBER_TEMPLATES
by jacob_bondski 10 Sep '02

10 Sep '02

Hi, The VC++ compiler (6.0 with SP 5) has problems with member function templates. We have encountered a couple of situations where a shared_ptr was created and an attempt was later made to assign a raw pointer to it. However, 1) The compiler fails to recognise that you can't assign a raw pointer to an existing shared pointer object 2) The compiler fails to generate any code whatsoever for the assignment 3) The compiler remains silent about its problems We realise that one way to help the compiler to recognise invalid statements is to undefine BOOST_MSVC6_MEMBER_TEMPLATES. We are now considering to enforce this undefine across our project. Does anyone know which boost features would become inaccessible? Regards, Jacob

function docs

Hi... I downloaded Boost 1.28.0. I looked at the function library folder but I didn't see any documentation on how to use this library. Where's it? If there isn't, who would volunteer and explain how to use this library? I am using gcc 3.2 on Win2000 and sometimes on Win98. Mo

Re: msvc-stlport build problems
by David Resnick 09 Sep '02

09 Sep '02

OK, here is the real fix to the problem. Rehash: Compiling for tool "msvc-stlport" fails with these errors repeated for many files: C:\PROGRA~1\MICROS~3\VC98\include\winbase.h(1011) : error C2733: second C linkage of overloaded function 'InterlockedIncremen t' not allowed C:\PROGRA~1\MICROS~3\VC98\include\winbase.h(1009) : see declaration of 'InterlockedIncrement' C:\PROGRA~1\MICROS~3\VC98\include\winbase.h(1018) : error C2733: second C linkage of overloaded function 'InterlockedDecremen t' not allowed C:\PROGRA~1\MICROS~3\VC98\include\winbase.h(1016) : see declaration of 'InterlockedDecrement' C:\PROGRA~1\MICROS~3\VC98\include\winbase.h(1026) : error C2733: second C linkage of overloaded function 'InterlockedExchange ' not allowed C:\PROGRA~1\MICROS~3\VC98\include\winbase.h(1023) : see declaration of 'InterlockedExchange' This problem occurs when the Platform SDK is installed. The PSDK include path must be searched before the standard MSVC includes. The bjam tool adds -I"C:\PROGRA~1\MICROS~3\VC98\include" to the cl command line, so that is searched before the PSDK include path which is specified in the environment. An immediate solution is to have the PSDK include path searched first, using this bjam command line: bjam -sTOOLS=msvc-stlport -sBUILD="debug release <stlport-iostream>on <sysinclude>C:\Progra~1\MIFD68~1\Include\." -sSTLPORT_PATH=c:\etc NOTE: "C:\Progra~1\MIFD68~1\Include\." is the short form of "C:\Program Files\Microsoft SDK\Include" on my machine. YMMV. This should probably be fixed in msvc-tools.jam which would somehow check if the PSDK is installed (by checking the environment?) and added to the header search path as needed.

boost:shared_ptr<> exception in checked_delete(..)
by Julia Donawald 09 Sep '02

09 Sep '02

Hi, I have written the following code to simulate my problem: #include <vector> #include <shared_ptr.hpp> class Foo { public: Foo() { }; virtual ~Foo() { }; }; class Vector_Foo { public: Vector_Foo() { }; virtual ~Vector_Foo() { }; void AddFooObject(Foo* pFoo) { FooDataPtr ptrFoo(pFoo); m_vecChildren.push_back(ptrFoo); }; protected: typedef boost::shared_ptr<Foo> FooDataPtr; typedef std::vector<FooDataPtr> FooVector; FooVector m_vecChildren; }; int main( ) { Vector_Foo vec; Foo* pFoo = new Foo(); vec.AddFooObject(pFoo); vec.AddFooObject(pFoo); return 0; } When I now leave the function main, and the vec-Object is deleted I got an exception in the function: template< typename T > inline void checked_delete(T * x) { typedef char type_must_be_complete[sizeof(T)]; delete x; } in checked_delete.hpp What have I done wrong? Why doesnt my code work? Should I use another class then shared_ptr to do that what I want, namely to insert 2 pointers to the same Object in a vector? Thanks in advance Julia

BUG in Regex++ 3.31
by Yaroslav Govorunov 09 Sep '02

09 Sep '02

Hello, All! Call to the regex_match(chkString,Match,Expression,match_not_dot_newline) causes program go into an infinite loop when chkString="http://localhost/ideas/exchange/June98/test/test.cfm" and Expression="^/(.*)*.cfm" Both Regex++ and test program are compiled with VC7.0 on WindowsXP. I have tried to play with optimisation settings, but this bug appears even in debug configuration. I understand that syntax of regular expression is incorrect, but library should rise error in this case. I hope that I'm doing something wrong and there is a workaround to this problem. With best regards, Yaroslav Govorunov, E-mail: slov(a)rsdn.ru http://www.rsdn.ru http://www.isapirewrite.com

Hi, the folllowing works not too: #include <vector> #include <shared_ptr.hpp> class Foo { public: Foo() { }; virtual ~Foo() { }; }; class Double_Foo { public: Double_Foo() { }; Double_Foo(Foo* pFoo1, Foo* pFoo2) : m_Foo1(pFoo1), m_Foo2(pFoo2) { }; virtual ~Double_Foo() { }; protected: typedef boost::shared_ptr<Foo> FooDataPtr; FooDataPtr m_Foo1; FooDataPtr m_Foo2; }; int main() { Foo* pFoo = new Foo(); Double_Foo DoubFoo(pFoo, pFoo); return 0; } I got the same error as in my former post. I read a bit about shared_ptr. Maybe it has something to do with a cyclic, but I thought in anohter case of cyclic data, namely if I have an object A which points to B and B holds a member which points back to A.... that's in my case not? If it has something to do with cyclic data then how can I solve it with weak_ptr? Thanks in advance Julia
