Good morning!

I am trying to compile a very simple Matlab function, just to test functionality using Matlab files for VB classes. It's shown below. I am using the Apps => Library Compiler function to compile the function.

function [ z ] = vbLibraryFunction( x, y ) z = x+y; end

I get the following error when trying to compile.

mcc -W 'dotnet:matlabSumTest,vbSum,0.0,private' -T link:lib -d \\path\for_testing -v class{vbSum:\\path\vbLibraryFunction.m} Compiler version: 6.0 (R2015a) Dependency analysis by REQUIREMENTS. {Error using matlab.depfun.internal.SearchPath (line 852) Database file "path\Software\Matlab\toolbox\matlab\depfun\+matlab\+depfun\+internal\requirements_win64_dfdb" does not exist. Please check that the path is specified correctly.

Error in matlab.depfun.internal.requirements (line 138) s = matlab.depfun.internal.SearchPath(target, varargin{2:end}); } Unexpected error while determining required deployable files. Compilation terminated.

I've checked the path given (path\Software\Matlab\toolbox\matlab\depfun\+matlab\+depfun\+internal\) for the requirements_win64_dfdb file, and I see it there, it's around 95 Mb.

Any help would be appreciated!

The error might be caused by file read/write permission issues. You can try the following workarounds.

Workaround 1:

Run MATLAB or the mcc or deploytool commands as administrator.

Workaround 2

Install MATLAB in a location where you can write to without administrator privileges.

Workaround 3

Give full read/write permissions to the the dependency analysis database files located at:

matlabroot\toolbox\matlab\depfun\+matlab\+depfun\+internal\requirements_arch_dfdb matlabroot\toolbox\matlab\depfun\+matlab\+depfun\+internal\pcm_arch_db
