problem compile between Lapack++ & MSVC Visual.net

Frédéric Degraeve

Hello,

My compiler is visual 7.1 ( Microsoft Visual C++ .NET ). I work on a
c++ library for a big company which do many scientific computes. I want
to integrate lapack++ inside the library by replacing a Matrix-like
type by LaGenMatDouble and an Array-like type by LaVectorDouble. May be
later, i will integrate also the complex types.

On the c++ library, there is a strange event where a pointer seems to
be changed and i really dont get why after a few hours of debugging.
I'm really surprised because Array and Matrix types arent involved
where the error comes.

I've made a small project with the project lapack and my interface
matrix and array. All is normal in release even with tricky checks.
Then i've activated the compilation with error detection from
DevPartner. It's a profiler for this visual c++. Its version is 8.1.
And then the surprise came. On output, everything is printed weird...

I've tried a lot of things without results... Do someone have an idea?
Do someone has realized some iterators for lapack++ LaGenMatDouble and
LaVectorDouble? I suspect my errors coming from there...

Thank you in advance for every ideas!

Fred

Before someone replies to you rudely (which seems pretty common in this
group), I'm going to do it politely. As a general rule this group is for
discussing Standard C++; that means that it's not for discussing specific
compilers ("visual 7.1"), libraries ("lapack++") or proprietary technologies
("Microsoft Visual C++ .NET", "DevPartner "). Some people get remarkably upset
about this.

It also means we're unlikely to know much about such a very specific problem
as yours, since it concerns so many things we don't discuss. I, for instance,
don't use Visual C++, much less DevPartner or Lapack++, and know nothing
about them. I recommend you try to find a newsgroup or mailing list devoted
to Lapack++ or DevPartner, and ask there: not only will you get more responses,
but they'll be from people who know much more about the technologies involved.

Hope that helps,
Tom
