linker errors

Hi Experts,
I'm converting an MFC project written in VS2008 to VS2010 - I'm getting loads of linker errors:

3>cppunitd.lib(TextTestRunner.obj) : error LNK2019: unresolved external symbol "__declspec(dllimport) public: int __thiscall std::ios_base::width(int)" (__imp_?width@ios_base@std@@QAEHH@Z) referenced in function "class std::basic_ostream<char,struct std::char_traits<char> > & __cdecl std::operator<<<struct std::char_traits<char> >(class std::basic_ostream<char,struct std::char_traits<char> > &,charconst *)" (??$?6U?$char_traits@D@std@@@std@@YAAAV?$basic_ostream@DU?$char_traits@D@std@@@0@AAV10@PBD@Z)

They are all problems with linking to the std library... Not sure why they are not being found...

It's a solution with 45 projects in it... Not sure where to start ;-)

But it's compiling fine - it's just the linker.... It can't be a #include or a using clause if it's at the link stage right?

But those are not my projects - not even sure where they come from or what they're for...

Aha! It was my test project - it uses unit testing... Builds when I unload the test project......

Cool. Nice shirt, by the way. I like the color.

If you look at the times on the threads it is clear that http:a#34158397 gave the asker the information which lead to the solution. It pointed out the source of the errors and was therefore part of the solution.
That one and http:a#34158436 (the asker's post) provide the complete solution to this post.

Apologies for not giving points sooner.
