DLL calling another DLL (error -127)?

["Buttrey, Samuel" <sebuttre@nps.navy.mil>]

Hi. I'm trying to incorporate calls to CLAPACK into some existing C code,
which I then want to link into S-Plus. (I'm using S-Plus 2000 Professional,
Release 3 on NT 4.0.)  So I create my DLL (using Microsoft Visual C++ 6.0)
and point it to the CLAPACK DLLs, and it links successfully. Now I want to
dll.load() that DLL so I can call my function. However dll.load() returns
error -127, which is not documented. Can anyone tell me what I'm missing? Do
I somehow need to let S-Plus which symbols I'll need from those other DLL's?

Thanks for any input,
