building boost under mingw: bjam invokes VC7??
by Brewer, Christopher 13 Jul '04

13 Jul '04

Hello, all- I recently attempted to build and install boost 1.31.0 using msys (i.e., mingw). I enter the boost directory and start bjam with: bjam -sTOOL=mingw install ...and then I see bjam invoking vc7 instead of gcc. For example: "C:\Program Files\Microsoft Visual Studio .NET 2003\VC7\bin\cl" ... followed by many, many errors, as VC7 is not installed on my system. I don't understand why bjam thinks it should be using VC7. Can anyone offer any advice or a workaround? I'm using the latest version of both msys and mingw under Windows 2000, and mingw is installed *under* msys, if that makes a difference.

Limitation of boost::protect of Boost.Bind
by Sigg＠inf.ethz.ch 13 Jul '04

13 Jul '04

Hi, I would like to bind a function which takes a boost::function<void> as parameter, let's say void caller(boost::function<void (void)>& f) { f(); } void foo() {} boost::function<void (void)> foo_fun = &foo; boost::bind(caller, foo_fun)(); But what if the function has a parameter, for example void bar(int i) {} How can I create the folling a function object? boost::function<void (int)> The function object should take an int, bind it to bar and then call caller with the resulting nullary function. boost::function<void (int)> bar_fun = &bar; // doesn't work because caller and bar are being composed. boost:bind(caller, boost::bind(bar_fun, _1)) // doesn't work because caller doesn't accept a unary function. boost:bind(caller, boost::protect(boost::bind(bar_fun, _1))) Does anyone have a clean solution for that? boost::protect doesn't provide the option to evaluate the arguments (_1) but _not_ perform a composition. Regards, Christian

Fw: Parser error from semantic actions
by Hermann Oliveira Rodrigues 12 Jul '04

12 Jul '04

Hi, How can I inform an error from a semantic action? Consider the following code: rule = IDENTIFIER[ callback_a( m_varBinder, &VarBinder::bind ) ]; callback_a is an actor allowing member calls in semantic actions. VarBinder::bind receives an identifier and try to locate it in an external symbol table. If bind fails, I like to inform a parser error back to Spirit. How can I do that? Pointers to the relevant parts in the documentation are welcome. Hermann [My apologies for sending a Spirit specific question to boost-users lists. However, I getting an administrative error from the sourceforge mail server]

Help with tuples - repeated members
by John.Wismar＠autozone.com 12 Jul '04

12 Jul '04

I've been playing with Boost's tuples library, but I'm having some trouble working through a wrinkle: I have some routines that use tuple<int>, tuple<int, int>, etc., up to tuple<int, int, int, int, int>. I'd like to be able to declare these objects using an alternative notation, along the lines of: tuple_clone<int, 1>, tuple_clone<int, 2>, tuple_clone<int, 3>, etc. The objective would be to allow me to write a function template that looked something like this: template <int N> tuple_clone<int, N> fn(tuple_clone<int, N-1> t) { tuple_clone<int, N> ret; ret.get_head() = getValue(); ret.get_tail() = t; return ret; } Each time I try to write tuple_clone, though, I end up stumped. Is it possible to write something like this, while leveraging the tuples library? Or is there a different approach I ought to look into?

FW: "memory access violation" in boost::serialization
by Dirk Griffioen 12 Jul '04

12 Jul '04

Hi, I encountered the following little problem: I would like to use the following datastructures with boost::serialize: struct Match {}; typedef std::string Key; typedef tst< Match, Key > TernarySearchTree; //this one has a shared_ptr typedef std::vector< TernarySearchTree > Trees; typedef std::map< std::string, Trees > Symbols; I have defined some serialize overloads so saving goes fine, but when loading I get a "memory acces violation" inside the following code: { boost::archive::text_iarchive ia(ifs); ia >> symbols_; } More specific, inside <boost/serializiton/shared_count.hpp> void add_ref_copy() { #if defined(BOOST_HAS_THREADS) mutex_type::scoped_lock lock(mtx_); #endif ++use_count_; } Which constructs a scoped_lock, and there, the "explicit scoped_lock(lightweight_mutex & m): m_(m)" seems to go wrong. What could be the reason? The more since all worked fine (saving and loading) when I used a simple vector of tst's. Is it not possible to use a map of string/vector (the error seems to suggest the library failing when copying vector to map - eg ++use_count of the shared_ptr inside the TST). Thanks in advance, Dirk

Re: Sun Solaris Forte 8 and boost_1_31_0
by Yaron Hirsch 12 Jul '04

12 Jul '04

Hi, I've also tried to compile RegEx with Forte 8. Did you try that? I think I managed to get things to compile, but unfortunately, when I try to compile it in 64-bit mode, we still get problems. Is there any chance you've tried compiling it in 64-bits? Thanks.

Problem about build regex under win32 using stlpot5.0
by huangliang 12 Jul '04

12 Jul '04

Recently I begin to use stlport in my programs, and I want to build boost regex under win32 using vc6 and stlport 5.0. But when I build them,the following errors occurs: C:\lib\boost-1.30.2\libs\regex\build>set MSVCDIR= D:\Program Files\Microsoft Visual Studio\VC98\Bin C:\lib\boost-1.30.2\libs\regex\build>set STLPORT_PATH=E:/HuangLiang/c++stl/STLport-5.0-1031 C:\lib\boost-1.30.2\libs\regex\build>nmake -fvc6-stlport.mak cl /nologo /MT /W3 /GX /O2 /GB /GF /Gy /IE:/HuangLiang/c++stl/STLport-5.0-1031\stlport /I..\..\..\ /D_MT /DWIN32 /DNDEBUG /D_MBCS /D_LIB /YX /FD /c -Fpvc6-stlport/boost_regex_vc6-stlport_mss/boost_regex_vc6-stlport_mss.pch -Fo./vc6-stlport/boost_regex_vc6-stlport_mss/ -Fdvc6-stlport/boost_regex_vc6-stlport_mss.pdb ../src/cpp_regex_traits.cpp cpp_regex_traits.cpp ../src/cpp_regex_traits.cpp(662) : error C2660: 'isspace' : function does not take 2 parameters ../src/cpp_regex_traits.cpp(662) : fatal error C1903: unable to recover from previous error(s); stopping compilation After I searched msdn, I found that isspace have been defined at 2 places: isspace template<class E> bool isspace(E c, const locale& loc) const; The template function returns use_facet< ctype<E> >(loc). is(ctype<E>:: space, c). and in ctype.h. I remember when I compile regex using vc6 without stlport, no same errors occured. I need some help about what has happened with me. Thank you !

RE: [Boost-users] Generic Class Factory
by Mark Loew 09 Jul '04

09 Jul '04

I have been looking at Andre Alexandrescu's book Modern C++ Design. He has the Loki library in there. That has all of the pieces that are needed. Does anyone know of any issue with mixing Boost, ATL and Loki? A side question is has anyone looked at merging the Loki library into the Boost library. It seems like a really great fit as the Loki library deals with a different set of problems.

Failed build using vc7.1
by Owen Jacobson 09 Jul '04

Salve. I'm trying to use boost.threads in my project, as they look like the cleanest cross-platform threading interface I've seen in a while, and I'm running into a wee problem convincing the libraries to build. My setup: Windows 2000 SP 4 Microsoft Visual C++ 7.1 (C:\Program Files\Microsoft Visual Studio .NET 2003\VC7\) MS SDK (U:\Program Files\Microsoft SDK) Boost 1.31.0 (C:\boost_1_31_0, installing to C:\boost) Cygwin is installed, but not present in PATH; I am not using cygwin to build this project, only to run PostgreSQL. Python is not installed, as I have no need for it. Visual C++ 6.0 is also installed (for legacy projects), but not present in PATH. bjam is present in PATH, as downloaded from Sourceforge. C:\boost_1_31_0> bjam -v Boost.Jam Version 3.1.9. OS=NT.

Any suggestions? Owen
