MATLAB: Error with compiled program using Instrument Control Toolbox and NI-SCOPE

Instrument Control ToolboxMATLAB Compilerni-scope

My program communicates with National Instrument digitizer NI PCI 5922 using Instrument Control Toolbox and NI-SCOPE. I complied it with Matlab Compiler. The compiled program returned an error:

Error using icdevice (line 233)

Undefined function 'privateIviCLoadlibrary' for input arguments of type 'cell'.

system: Matlab 2014a 32 bit on windows 7 64 bit

MATLAB: Do I get “Failed to load shared library.” error when using NI-DCPower support package (or IVI-C driver) with ICDEVICE in Instrument Control Toolbox (64-bit MATLAB)

There might be multiple causes that can cause this since the error is very generic.

Make sure that the latest version of NI-VISA (5.1 or later) is installed. Older versions of NI-VISA (5.0) are missing some required header files.
Using IVI-C drivers (such as NI-DCPower) with 64-bit MATLAB (R2014a and earlier) installations require a properly installed and configured C++ compiler (as opposed to 32-bit MATLAB installations, which include a compiler)

Run mex -setup to check whether a valid compiler has been configured.

>> mex -setup

If there is no compiler configured, then the expected error would be:

>> ictObj = icdevice('nidcpower.mdd', 'DAQ::PXI1Slot1', 'optionstring','simulate=true');

Error using icdevice (line 233)

A 'Selected' compiler was not found.

You may need to run mex -setup.

However, in case of a failed Windows SDK 7.1 installation, the error might be:

>> ictObj = icdevice('nidcpower.mdd', 'DAQ::PXI1Slot1', 'optionstring','simulate=true');

Error using icdevice (line 233)

Failed to load shared library.

MATLAB: Am I unable to use NI-SCOPE, NI-DMM, and NI-DCPOWER in combination with Instrument Control Toolbox R2014a

Note that this is a generic error message and this discussion refers only to a particular issue in MATLAB R2014a with some NI driver packages installing NI VISA 5.0, which had an issue with a missing header file (vpptypes.h).

The NI-SCOPE package 3.9.7 includes NI-VISA 5.0 which is missing a number of required header files.

Other packages which include NI-VISA 5.0 and may thus run into similar issues are:

NI-DMM
NI-DCPOWER

To resolve this issue please manually install the latest NI-VISA version (<http://www.ni.com/visa/>) after having installed NI-SCOPE, NI-DMM, or NI-DCPOWER.

If you see this error in a more recent MATLAB release it's probably caused by a different issue.

Note than NI VISA can be installed by a support package since R2015a (<https://www.mathworks.com/hardware-support/ni-visa-keysight-visa-tekvisa.html Instrument Control Toolbox Support Package for National Instruments VISA and ICP Interfaces>)
