This is a problem with the standard library implementation. Although VC++ 6 has some support for template member functions, the library that comes with it was written for an earlier version that did not and was not updated to include template member functions. So it does not define the constructor template for std::deque that takes two iterators (though it does define a constructor that takes two const T * pointers, where T is the element type). I think the example will work if you install STLPort or Dinkumware's newer library as a (partial) replacement for VC++ 6's standard library.

Problem Building boost for cygwin g++ with stlport on WinXP
by Markus Ruettimann 06 Jan '04

06 Jan '04

Hi all I'm an enthusiastic user of boost since quite a long time. I used MSVC6.0 so far. How ever, I changed to cygwin g++ 3.3.1 for project reasons. I have succesfuly built the latest STLPort version (4.6) and I also use it successfully. How ever, I am not able to build the toolset gcc-stlport. There are errors in the threadding lib and elsewhere, and such ugly things as "to long path names" errors in the console. Does anybody know how to build this toolset and link them together as one static lib? I use boost-1.30.2 with cygwin g++ 3.3.1 on winXP professional. PS: When I build the bjam stuff, what builds without any errors, it uses the MSVC compiler (the output it creates looks like this). Is this a problem? Thanks for your help Markus. -- Using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/

Spirit Example does not build
by John 06 Jan '04

Hi, I have been trying to get one of the spirit examples, regex_convert to build using VC6, service pack 5. I am using boost 1-30.2 for this exercise. I get the following error message. error C2664: '__thiscall std::deque<char,class std::allocator<char> >::std::deque<char,class std::allocator<char> >(unsigned int,const char &,const class std::allocator<char> &)' : cannot convert parameter 1 from 'class std::istreambuf_iterator<char,struct std::char_traits<char> >' to 'unsigned int' No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called I was wondering if this was a known issue, or if there was something else that I needed to do. cheers John

Longest path in a DAG using BGL
by Ramprasad Natrajan 03 Jan '04

03 Jan '04

Hi, I am trying to find the longest path in a DAG using the BGL Dijkstra function. The call I used is: dijkstra_shortest_paths(hcg, s, &p[0], &d[0], weightmap, indexmap, std::greater<int>(), closed_plus<int>(), 0,MAXINT,dijkstra_visitor<null_visitor>()); where MAXINT is set high enough to be greater than the maximum path length. This doesn't seem to do the trick. Any suggestions? Thanks a real lot, Ram _________________________________________________________________ Feeling like a vacation?

how to get started? (not in documentation)
by Tom Weber 01 Jan '04

01 Jan '04

Hello, I downloaded boost today so regard me as a newbie. Boost seems great, but the documentation doesn't mention how I should install boost on my system (redhat 9), and how to link against the built libraries. Sure I can include it in every project (though it's huge!), and make the makefiles link into strange locations such as libs/test/build/bin/libboost_unit_test_framework.a/gcc/debug/runtime-link-static/threading-single/libboost_unit_test_framework.a Is there an easier way? Why aren't packages like boost-[devel-]VERSION.PLATFORM.rpm made? Why aren't all built libraries put in the same directory, with a simple path name? Why isn't the thread library built statically? Is putting a "lib" section with BOOST_THREAD_BUILD_STATIC=1 in the Jamfile a legal fix? (seems to work) Also... I think boost should have a network library. Can anyone recommend a platform-independent network library? I'm thankful for any answer... -- Cheers, Tom Weber http://www.dd.chalmers.se/~np98towe/
