I just looked into the one for P4 and it does export zdrot_ and works
for me. Is your one from CRAN master?

I encountered the following problem in R-2.4.0 for Windows binary downloaded

from CRAN (data from R-help post by Ethan Johnsons).  I was also using the
contributed binary Rblas.dll for Intel P4 chip.  The problem doesn't occur with the
default Rblas.dll.

I got the following popup window error message

   The procedure entry point zdrot_ could not be found in the dynamic link library

Rblas.dll

After closing the popup, the following was printed in the console:

Error in chol2inv(Qr$qr[p1, p1, drop = FALSE]) :
        lapack routines cannot be loaded
In addition: Warning message:
unable to load shared library 'C:\R\R-2.4.1beta/modules//lapack.dll':
  LoadLibrary failure:  The specified procedure could not be found.

I subsequently downloaded R-2.4.1beta from CRAN and had the same problem with

the contributed binary Rblas.dll

OS:  WinXP Pro service pack 2

I haven't had any problems with the contributed binary up thru R-2.3.1.  I checked

the changes file and saw that for R-2.4.0 the Rblas.dll would have to be recompiled,
but also that the contributed binaries on CRAN had been updated.  However, I
couldn?t find any Rblas binaries with a date after 2005.  Any suggestions on where to
find an Rblas binary for WinXP and P4 chip, or do I need to try to compile one on my
own?

Thanks for any assistance,

Dan
