Success! I added the "_bi::" at lines 206 & 208 of boost/bind.hpp & the compile was successful.

serialization library - reloading objects
by Sergey Skorniakov 07 Dec '04

07 Dec '04

Hello, All! Are there any way to load existing objects by base class pointer without creating new? Examination of input archives source code does not give me any idea how I can achieve it. I think I need some mechanism for runtime switching archive object tracking behaviour in that way so all objects will interpreted as already created (or per-object tracking registration without actual object loading to pre-register pointer to object as already created before object loading). With best regards, Sergey.

Boost Python installation Windows XP+Visual C++ 7.1
by Nguyen Xuan Son 07 Dec '04

Hi, My problem is the following 1/ I install Python 2.4 at D:\Programs\Python24 using the binary file from www.python.org 2/ following the document from the boost.org I type the command >bjam "-sTOOLS=vc-7_1 --with-python-root=D:\Programs\Python24" stage But I receive the following error > --with-python-root=D:\Programs\Python24-tools.jam: Invalid argument I think I do something wrong here. If I use the simple command >bjam "-sTOOLS=vc-7_1 " stage I get the message: >skipping Boost.Python ..... Can someone show me how can I install Boost.Python correctly? Thanks Xuan Son

------------------------------ Toon Knapen wrote: This is again the old include-policy problem. Previously the headers of ublas were not self-contained. This has been fixed but only on a branch (and thus not in the 1.32 release). I plan to merge this branch also to the HEAD. For now, you just need to include storage.hpp before you include lu.hpp. In that case, on line 24 of lu.hpp will it recognise unbounded_array (which is defined in storage.hpp) ------------------------------ Toon, Thank you for the response! I was unaware of this include-policy problem. Will you be merging this code soon? I will try to look for your email about this merge. I tried fixing this within lu.hpp and it appeared as if errors were being added recursively so I gave up and posted the question. Since adding #include<storage.hpp> to lu.hpp didn't fix the problem, should I expect to have to include additional files to my code to fix errors in files such as storage.hpp? Thanks again for your time and effort, - dan elliott

It's a constrained unsigned short with a min of 1400 & a max of 10000. The as_number function was added to greg_month and greg_day to ease math operations. Since greg_year is a constrained value math simply "works", as does operator<<. Is there a specific reason why you'd like one added to greg_year? Thx, Bart

Depnding on how you're compiling your code, this may explain the linker error. I rebuilt (and downloaded 1.32 along the way) and now libboost_regex-gcc.so is a hard link to libboost_regex-gcc-1_32.so.1.32.0. I don't believe it was before (could be wrong) Anyway, compiling with the generic name now works great, thanx.
