I am building with VS 2008 and the compiler (cl) and the standard
libraries that goesÂ withÂ
it, including the windows thread library. I have noted that ompi_info
requiresÂ eitherÂ PosixÂ
or Solaris threads to report that open-mpi has thread support.Â Do I
Â need to changeÂ theÂ
thread libraryÂ and/or do I need another compiler?

Not all Windows compilers work well enough with all threading models
that you could expect satisfactory results; in particular, the
and thread libraries you use on linux may not be adequate for Windows
