Thread Subject: loadlibrary addheader

Hello,

I have created abc.dll where i use va_list in abc.h file and have included abc.h, stdarg.h and stdio.h in its abc.cpp file.Now i want to load this abc.dll in matlab.
I used the following command
[n,w] = loadlibrary('abc.dll','abc.h','addheader','stdio.h','addheader',stdarg.h')

But I get the error message:
w = Type 'va_list' was not found. Defaulting to type error.

How can this be solved?

Regards,
Varun.

You missed this line in the loadlibrary documentation:
addheader Loads the functions defined in the additional header file,
hfileN. Note that each file specified by addheader must be referenced by
a corresponding #include statement in the base header file.

So you must add #include statements to 'abc.h' for stdio.h and stdarg.h.

Any function using a va_list will not be callable from MATLAB so the
warning can probably be ignored with no harm done.

Once you add the headers to abc.h you will find that you probably did
not want to use the addheader option.
