loadlibrary issue with dll

Hello,

I'm trying to load a vendor dll and header file and call from Matlab. I've been able to successfully call this dll from Python, but I'm having mixed results in Matlab.

The library loads without out errors and it appears that I'm able to connect to the device (Total Phase Aardvark). However, a simple function call to turn on the target power does not work (it doesn't throw errors though).

The dll and header file are attached. Any thoughts on why this isn't completely working? Here is the code that I've been using.

%load dll shared library
[warnings, notfound] = loadlibrary('aardvark','aardvark.h');

This line returns several warnings:

the return variable notfound shows that some of the data types have errors which I feel may be the source of why it isn't completely working.

Despite the notfounds and warnings I'm able to successfully connect to the device using:

aa_handle = calllib('aardvark','c_aa_open',0);

aa_handle returns a 1 which based on the dll documentation indicates it's a valid handle.

At this point I should be able to issue lib calls to functions such as turning on the target power. However, the device does not appear to respond to this function call (although it does using Python):

%turn on adapter power 0x03
calllib('aardvark','c_aa_target_power',aa_handle,3);

[Philip Borghesani]

These lines of code :

 typedef unsigned __int8   u08;

Are making use of a Microsoft extension to the c language ( __int8 ) and are not supported by loadlibrary. There may be no easy solution to the problem. I would probably make a copy of aardvark.h and edit it as need to make loadlibrary work. Your other option is to give up on loadlibrary and create your own mex file.

To make a modified version of aardvark.h work the typedefs secion might need to look like:

 typedef unsigned char   u08;
 typedef unsigned short  u16;
 ...
 typedef char   s08;
 typedef short s16;
 ...

To get the include of aardvark to work correctly you might need to change it to

#include "aardvark.h"

That is standard c syntax if the header is in the same directory and not on the include path.

[tmd]

Philip,

Once I changed #include aardvark.h to #include "aardvark.h" Matlab was able to run loadlibrary without throwing errors, but the datatype issues still existed.

However, changing the type definitions directly in aardvark.h has resolved the problem! Thanks for all the help!

For others, here is what I changed in aardvark.h:

/* Microsoft compilers (Visual C++)*/

typedef unsigned char u08;
typedef unsigned short u16;
typedef unsigned long u32;
typedef unsigned long long u64;
typedef signed char s08;
typedef signed short s16;
typedef signed long s32;
typedef signed long long s64;

[justin]

On a very similar issue, I am trying to load a .h file with

typedef struct _D128STATE {
  unsigned int CONTROL;
  int DEMAND;
  int WIDTH;
  int RECOVERY;
  int DWELL;
  unsigned int CPULSE;
  unsigned int COOC;
  unsigned int CTOOFAST;
  unsigned int FSTATE;

} D128STATE;

typedef struct _D128DEVICESTATE {
  int D128_DeviceID;
  int D128_VersionID;
  int D128_Error;
  D128STATE D128_State;
} D128DEVICESTATE;

typedef struct _DEVHDR {
  int DeviceCount;
} DEVHDR;

typedef struct _D128 {
  DEVHDR Header;
  D128DEVICESTATE State[];
} D128, *PD128;

and more typedef structs similar. that returns

Warning: The data type 's_D128DEVICESTATE#' used by structure s_D128 does not exist.
The structure may not be usable.

I have gotten loadlibrary to work with other headers and dlls, but they never attempted to typedef a struct. Is there a similar fix to the int/short/long one??

[Niravkumar Ambaliya]

Hi Justin,

Were you able to solve the problem? I am getting similar errors when using structs having struct array.

Thanks,

[Walter Roberson]

You may need to use a later compiler, or you might need to set your compiler to c99 mode. See also http://stackoverflow.com/questions/734802/fixed-width-integers-in-c

[tmd]

I'm not sure I understand what your're saying. I'm not compiling anything, outside of Matlab that is. Are you saying I need to change Mex to c99 mode?

I've found other people have similar issues, albeit with different data types, which have been resolved by adding include statements in the headers file (windows.h, stint.h, etc.) but these have not worked for me.

[Walter Roberson]

Yes I think you will need to change mex to c99 mode. Also earlier versions of the microsoft compilers did not define __int* variables, which are microsoft specific anyhow. If using a later microsoft compiler with c99 mode does not solve the problem with the __int* types then the link I gave talks about where to find appropriate header files to account for these microsoft built-in types.

Answer 3

[Philip Borghesani]

I do believe the problem is a missing header. The addheader loadlibrary option is NOT the solution by itself. Start with a c example that calls the function and look at all header #included before aardvark.h one or more of these is likely the problem. The simplest solution is to create a new header file (myheader.h) and add all includ statments from the example up to and including the include for aardvark then call

 loadlibrary('aardvark','myheader.h','addheader','aardvark')

If you still have no progress post the header code for a few of the functions and the matching lines with comments from a prototype file created with the mfilename option to loadlibrary.

[tmd]

Philip - thanks for the suggestion. Unfortunately it didn't solve my issue. I looked through several of the C examples and they all seemed to have stdio.h, stdlib.h and string.h includes before the aardvark.h.

So I created a simple header file (myheader.h) which just contains:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

The 3 files (aardvark.dll,aardvark.h, and myheader.h) are all located in my Matlab working directory.I then issued the loadlibrary line that you posted but the library won't load now:

>> [warnings, notfound] = loadlibrary('aardvark','myheader.h','addheader','aardvark')
Warning: No functions found in library. 
> In C:\Program Files\MATLAB\R2014b\toolbox\matlab\general\loadlibrary.p>loadlibrary at 431 

warnings = 

     Empty cell array: 1-by-0

notfound =

myheader.h

Type 'longdouble' was not found.  Defaulting to type error.

Found on line 9719 of input from line 139 of file C:\\Program Files (x86)\\Microsoft Visual Studio 10.0\\VC\\INCLUDE\\stdlib.h
Warning no reference to header 'aardvark' added with addheader was found in source.
aardvark_thunk_pcwin64.c

>> libfunctions aardvark

No methods for class lib.aardvark.

Using this command I generated the matlab function prototype file:

[warnings, notfound] = loadlibrary('aardvark','aardvark.h','mfilename','aardvarkprototypefile.m')

I've attached 'aardvarkprototypefile.m' (formatting makes it unreadable). Notice the 'error' and 'errorPtr' in the input arguments of the functions. I know that this is the problem, but I just don't know how to solve it.

[Philip Borghesani]

u16 and similar types are not standard types and the definition must be in some header file. It is possible that Walter is on the correct track and that the definitions are using c99 types that are not supported by loadlibrary and your combination of compilers.

Your header myheader.h is not correct it is missing #include <aardvark.h> you missed the "up to and including" in my instructions above.

What platform, MATLAB version and compiler are you using? This may need to be a support call or enhancement request.

What code is on line 79 of aardvark.h?

[tmd]

Hi Philip,

I added the '#include aardvark.h' into myheader.h but Matlab can't seem to load the header file now despite the file being in my workspace.

>> [warnings, notfound] = loadlibrary('aardvark','myheader.h','addheader','aardvark')
