Importing Matlab DLL into LabWindows/CVI

[mco]

I am new to the LabWindows/CVI & TestStand environment but trying to import
Matlab 2008a DLLs into LabWindows/CVI but when compiling the MatLab
generated H files I keep generting redefinitions. As an example, here are a
few

"wchar.h"(78,31) Redeclaration of '_ctype' previously declared at
ctype.h:33.
"wchar.h"(84,52) Redefinition of macro '_UPPER'.
"win.h"(2907,40) Redefinition of macro 'THREAD_PRIORITY_ABOVE_NORMAL'.
"win.h"(2908,43) Redefinition of macro 'THREAD_PRIORITY_BELOW_NORMAL'.

Has anyone been successful with importing a MatLab DLL into CVI? Any
suggestions would be appreciated or am I wasting my time???

Try changing the order of your include files (matlab first).

Hello Michel,

If the previous post does not work for you, you might also try using preprocessor directives such as #ifdef and/or #ifndef to avoid redefinition.

Thanks for the suggestion of changing the order of H files as it has fixed
most of the problems. I am trying to used the Options-Build Options to add
compiler defines but not able to get to work. Do I need something special to
have the compiler use the defines I have added or just add to my own H
files?

Michel,

You should be able to type the preprocessor directives directly into your header file without configuring any of the environment options.  I have the default options that were set with installation and it allows me to build a project with these directives.
