loadLibrary and .dll problem

[jseubert]

I am having a problem with the compiler and an outside .dll library. A program I wrote to simply open the library and then close it works fine in matlab but when I compile the program I get errors that lead to it force closing, specifically with the loadlibrary function call. The resulting explanation is:

??? Error using ==> loadlibrary at 474
There was an error loading the library "C:\Program Files\MATLAB\R2009a\DVImgAccess_110207\dv_img_io.dll" Undefined function or variable 'dv_img_io_proto'.

Error in ==> DVImgLibOpen at 12

Error in ==>DVLibTest at 3

Caused by:
Error using ==> feval
Undefined function or variable 'dv_img_io_proto'.
MATLAB: UndefinedFunction



DVLibTest is the program that opens and closes the library. DVImgLibOpen is the function call that opens the library. Its code looks like this:
function [] = DVImgLibOpen(ListFunctions)

LibPath = dvimgroot();
tf=ispc;
if tf ==1
SharedPath = fullfile(LibPath, [DVImgLibName '.dll']);
else
SharedPath = fullfile(LibPath, [DVImgLibName '.so']);
end
HeaderPath = fullfile(LibPath, [DVImgLibName '.h']);

loadlibrary(SharedPath,HeaderPath);

if ListFunctions ~= 0
libfunctions (DVImgLibName) -full
end

Any help?

Thanks!

May be a bit late but is dv_img_io_proto defined in DVImgLibOpen?

where is dv_img_io_proto defined? in DVLibTest?
Post DVLibTest if you haven't figured it out yet
