You need only to reference one library depending on your Settings->C/C++->Code Generation:Use run-time library value. The extension should tell you right away which version it is you need.

Hi, It seems that you simply have not linked to the regex library. BTW, I believe the name is "regex" and that "Regex++" was the name before John Maddock ported his library to boost. Regex is one of boost library that does not consist only of headers. It needs an actual binary to link to. Which means you have to build it yourself. Have you gone through this stage ? If not I suggest you do not go through Bjam for this one and instead go to boost/libs/regex/build and run the VC7 make file there (vc7) inside the VC7 command console. If memory serves, it produces the complete set of static and dynamic libraries you need whereas Bjam does only part of it (or maybe I could not make it work properly). Then in your settings in the link tab put the path to the library you want to use (I believe a pragma lib takes care of choosing the one compatible with the version of the C library you compile with). Kind regards, Cyril Godart.

Is threads CodeWarrior project broken?
by Steve Folly 04 Nov '03

04 Nov '03

Hi, I'm trying to build the threads library on Codewarrior with the .mcp project supplied in libs/thread/build/ (using CW9, OS X 10.2.8), but Codewarrior says the file is not a project file. Is it broken? I could probably recreate it, but I'm not sure about about what source files to include for the Mac - there's all the extra stuff under src/mac/ and then what about the src/mac/msl_replacements/ stuff? Any help gratefully received. I'd like to do a multi-target project for Mac and Win32; tips for source files for Win32 would be helpful too. Thanks. Steve.

This is a documented limitation of the lambda library - there is no way to defer lookup of member names (overloading -> just changes the type and value of the pointer used) so member access can't be done on a placeholder. > I know I could use a functor object but this is just an example for a > more general need. Sorry, you'll have to define functors. These template functor classes might be useful: template<typename C, typename V, const V C::* P> struct lookup_member_const { const V & operator()(const C & c) const { return c.*P; } }; template<typename C, typename V, V C::* P> struct lookup_member { V & operator()(C & c) const { return c.*P; } }; Mind you, there might be similar things in Boost already.

Build+Install+/Zc:wchar_t in Visual studio builds
by John Maddock 01 Nov '03

01 Nov '03

Guys, Rene's new Install code is working very well for me now, but I have a question about how we're building with Visual Studio .NET. Currently the vc7 and vc7.1 toolsets turn on /Zc:wchar_t unconditionally when building, however this is not the default option in current versions of the IDE, and of course the two options produce binary-incompatible libraries (at least as far as regex is concerned). How should we handle this? At the very least I would like to see a bjam option to turn off /Zc:wchar_t, but how should we be building the libraries by default: turning native wchar_t support on is the standards conforming way, but not currently the default Visual Studio way, or the way many third party libraries (like ICU for example) are built. Does anyone know how this option interacts with MFC/ATL/VisualForms etc? We could of course create a new build variant to handle this, but with 8 regex lib/dll variants already I'm not keen to add another 8 (apart from anything else testing already takes too long). I'm cross posting this to the Boost.users group as well, since whatever resolution we take will affect them the most :-) Thanks, John.

[newbie] creating a (complex?) C++ wrapper around a C function call...
by Jason House 31 Oct '03

31 Oct '03

I want to create a wrapper function template <class foo> op_pk_fd_set_class(packet *packet, int index, foo &value, int simulated_bits); around the following function... (in OPNET) op_pk_fd_set( packet* pkptr, // same as in wrapper int index, // same as in wrapper int some_constant, //OPC_TYPE_STRUCT void* value, int simulated_bits, // same as in wrapper void* (*copy_proc)(void* obj_to_copy,int alloc_size), void (dealloc_proc*)(void *obj), int alloc_size); I believe dealloc_proc can just be a function pointer to the destructor. I could very well be mistaken, but I believe that a normal constructor takes only one parameter. I also think alloc_size should be sizeof(foo). I do not know how to obtain function pointers for constructor and deconstructor member functions. Any assistance I could get would be appreciated.

That appears to be a documentation bug. I checked this in VC++ 7.1 and _NATIVE_WCHAR_T_DEFINED is not defined by <cstddef>. There is no sign of a #define _NATIVE_WCHAR_T_DEFINED in the headers for version 7.0 or 7.1. > So Boost needs to use a macro which the end-programmer must define > which tells whether or not /Zc:wchar_t is being used or not, and > create another set of libraries accordingly. Even in the absence of a macro, this test works: #include <cstddef> #include <iostream> #include <ostream> #include "boost/type_traits.hpp" int main() { std::cout << "/Zc:wchar_t was "; if (!boost::is_same<wchar_t, __wchar_t>::value) std::cout << "not "; std::cout << "used\n"; }
