64-bit support for integer_traits on MSVC
by John Harris (TT) 17 Oct '02

17 Oct '02

It seems that there should be a way to get 64-bit integer support into integer_traits.hpp on MSVC. It looks like the only real problem is the missing feature of class constants, and the fact that integer_traits is using enums (which can't hold const_max and const_min values). But if there were specializations on the detail::integer_traits_base for MS 64-bit types, the constants could be declared in-class as __int64 but defined out-of-class (still in the header), safely. It's not as pretty as BOOST_STATIC_CONSTANT, but wouldn't it work? john harris trading technologies

min & max #undef'd by config.hpp?
by Chris Russell 17 Oct '02

17 Oct '02

I'm confused. Using MS Visual Studio 6.0 w/the Intel 6.0 compiler (or the native VC compiler for that matter) the min and max macros are defined in the MS header WINDEF.H. It seems that config.hpp #undef's these (although I haven't figured out where or why yet). My environment seems to be perfectly happy using std::min/std::max. But what of all these MS-defined macros that use the undecorated min/max? I really don't want to go chasing these down in the MS + third-party headers if I can avoid it. Will someone please explain to me what's going on with config.hpp? - Thanks & regards Chris Russell --- simple example --- #include <windows.h> #include <boost/config.hpp> #if defined(min) #pragma message "min is defined" #else #pragma message "min not defined" #endif #if defined(max) #pragma message "max is defined" #else #pragma message "max not defined" #endif int main(int argc, char* argv[]) { int a = 10, b = 20; int c = min(a,b); int d = max(a,b); return 0; } Deleting intermediate files and output files for project 'test - Win32 Debug'. --------------------Configuration: test - Win32 Debug-------------------- Compiling...

integrating shared_ptr and building with gcc 2.7.2
by Nik Kolev 16 Oct '02

16 Oct '02

Hi everybody: I would like to make some of my classes reference counted, and I like what shared_ptr offers. The problem is (or is it really?) that I am building (have to) with gcc 2.7.2. The gcc.h header file which is part of the shared_ptr library does not like versions of gcc prior to 2.9.0. I would greatly appreciate it if somebody could point out a way to use the boost's shared_ptr technique and build with gcc prior to 2.9 Thanks, Nik

newbie here. can't get anywhere with the regex search example
by suzanne 16 Oct '02

16 Oct '02

hi all. i'm brand new with this and just trying to figure everything out. i build the regex search example using VC++ 5, but i can't seem to make it 'go'. in debug mode, my argv (the name of a .cpp file) is blank! argc is incremented properly, so it's seeing something. but no value at all for the argv i'm feeding it - just a good old "". i've got to take this thing apart & learn it so i can implement it in a tool i'm building - can anyone help me get started? i want to step through the various examples to learn it. thanks, suzanne

RE: boost vs. The Lawyers (non-technical)
by Brian Neal 16 Oct '02

16 Oct '02

Thanks for the input so far. I too would like to call for some blanket license that all boost developers agree to (if possible). It looks like I'll be contacting developers individually and trying to get them to sign something for us. Not fun for either side I guess. Thanks, Brian Neal

[random] Known problems compiling random lib with Dinkumware STL?
by Chris Russell 16 Oct '02

16 Oct '02

I'm using the Intel 6.0 compiler under MS Visual Studio 6.0 SP6 and just attempted to plug the Dinkumware STL distribution into the mix. I ran into a slew of compile-time errors in the random library and am wondering if anyone has seen this before I ride into battle. Thanks - Chris

Yes. "Compiler support" can be seen as a courtesy by library experts, so they aren't trying to tell core language experts exactly how to do something. --Beman
